< Back Advances in Research from UFRJ and Embrapa on Coffee Gene that Increases Drought Resistance in Soybeans and Cotton Drought is one of the biggest challenges facing agriculture worldwide, causing significant losses, particularly in key crops such as coffee, soybeans, and cotton. Despite coffee's substantial economic importance, our understanding of how the plant responds to water scarcity at the molecular level is still limited. Research conducted by the Molecular Genetics and Plant Biotechnology Laboratory at UFRJ, led by Professor Márcio Alves-Ferreira, in collaboration with the team from Embrapa Cenargen, coordinated by researcher M. Fatima Grossi de Sa, studied all the "homeobox" (HB) gene family members present in the genome of Coffea arabica . They discovered that three of these genes are activated when the plant experiences osmotic stress (such as drought). Among these, the gene CaHB12 stood out as it is significantly activated in the leaves and roots of coffee plants under moderate and severe drought conditions. To better understand the role of CaHB12 , the scientists introduced this gene into transgenic Arabidopsis plants (a model plant) and observed that these plants exhibited increased tolerance to drought and salt during germination. During the analyses, they noted that while some classic drought response genes showed decreased activity, other pathways, such as those related to heat shock proteins, were activated, which may explain the enhanced resistance of the plants. This study was supported by the INCT PlantStress Biotech and also involved collaborations with the Universidad Nacional del Litoral (Argentina) and Universität Bonn (Germany). Furthermore, the researchers tested the expression of CaHB12 in transgenic soybean and cotton plants, with results indicating increased drought tolerance. The findings of this study, recently published in the journal Environmental and Experimental Botany , suggest that CaHB12 is a positive regulator of the stress response in coffee plants and a promising candidate for biotechnological applications.

< Back Agricultural Technology Revolutionizes Sustainable Production Young scientists associated with the INCT PlantStress Biotech bring Embrapa's innovations to the university. In recent times, Biotechnology has accelerated the genetic advancement of plants. The techniques employed in biotechnology have enabled the development of crops through gene incorporation. These genes not only enhance productivity but also provide resistance to drought, pests, diseases, and herbicides. Until the early 2000s, over 8,000 improved varieties were created for the 11 main globally cultivated plants. The adoption of these genetically enhanced plants resulted in a 21% increase in production in all developing countries between 1961 and 1980. In the period from 1981 to 2000, this growth reached an astonishing 50%. Genetic editing and the challenge of climate change Genetic editing allows for the creation of crops resistant to pests and diseases, reducing dependence on environmentally harmful pesticides. Additionally, it is feasible to develop plants that thrive in adverse conditions, such as acidic soils or water scarcity, making agriculture more adaptable to climate changes. In this way, for each plant species, there is a wide variety of cultivars, each with characteristics that favor their productivity in specific regions. This is why we can cultivate grapes, for example, in different regions of Brazil, such as the South, Southeast, and Northeast. Genetic editing is already generating new varieties better adapted to current climate conditions and will continue to enhance agriculture's productivity and climate resilience in the coming decades. The benefits of this approach go beyond adapting to climate change. New cultivars developed with CRISPR technology, for example, also play a fundamental role in reducing greenhouse gas emissions, decreasing the use of agricultural inputs, and preventing food waste, factors that support environmentally friendly agriculture. Sharing ideas and disseminating knowledge The integration of advanced technologies into agricultural sciences has become a topic of increasing relevance, offering significant opportunities to improve the production of natural resources, such as food, fibers, and renewable energy, while striving to protect and preserve these crucial resources for present and future generations. To promote the discussion of these topics and disseminate knowledge among students and future agribusiness professionals, the XVIII Agricultural Sciences Week, IX Research and Graduate Studies Conference in Plant Production, and VII Plant Genetics and Cytogenetics Conference had the theme "The Challenges of Incorporating Technological Tools: Production and Preservation of Natural Resources." The event, held at the South Campus of the State University of Goiás (UEG) from October 2nd to 6th, 2023, brought together professors, students, and technicians from the Ipameri Unit and other UEG units, as well as representatives from local and regional commercial institutions. During the event, Dr. Thuanne Pires Ribeiro, MSc. Luanna Pinheiro de Albuquerque Freitas Bezerra, and MSc. Valdeir Junio Vaz Moreira conducted the course "Genome Editing for Bioproduct Production," in which they taught university students the most advanced techniques for genetic transformation and editing in cultivated plants. Covering everything from fundamental principles of biology to the development of protocols for obtaining transgenic plants, these young researchers shared their knowledge and inspired students in the fields of Agronomy and Forestry Engineering at the institution.

< Back Underwater 'breathing' plants could be key to stress-resistant crops Wetland plants have a high tolerance against flooding due to the formation of "lysigenous aerenchyma," air channels that help transfer gases to the submerged roots. These channels also help the plant withstand drought and nutrient deficiency. Now, scientists from Japan investigate the underlying mechanism of aerenchyma formation to understand the phenomenon better, opening doors to the development of crops that are resilient against extreme weather changes. Floods and droughts are the main environmental disasters responsible for most crop failures. Aerenchyma formation can help crops cope with these environmental stresses. However, it is not commonly observed in non-wetland species like wheat and maize, which are staple food crops in certain areas of the world. Researchers Takaki Yamauchi and Mikio Nakazono from Nagoya University, Japan, have surveyed literature on the topic to get a concrete overview of the various factors involved in aerenchyma formation. "If we can genetically control the timing and amount of lysigenous aerenchyma formation in roots of all agronomically important crops, such as maize, wheat and soybean, the global crop production loss could be dramatically reduced," says Dr. Nakazono. Dr. Yamauchi and Dr. Nakazono suggest imagining the lysigenous aerenchyma to a snorkel used to breathe underwater. During flooding, the roots get cut off from oxygen and other vital gases needed for survival. In response, the plant creates air pathways connecting the submerged regions of the plant to the parts above water. Similar to a snorkel, these pathways help the plant "breathe" by transporting gases to the submerged roots. Moreover, the air channels reduce the energy requirement for the breathing process and can help the plant conserve energy during extreme conditions of drought or nutrient deficit. The researchers found that a phytohormone called "auxin" is required for the formation of aerenchyma during normal root growth, and identified two factors leading to the induction of aerenchyma formation in response to flooding. The phenomenon begins when the roots are submerged underwater in aerobic conditions. The restrictions to gas exchange cause ethylene to accumulate in the roots, which encourage the production of respiratory burst oxidase homolog (RBOH) -- an enzyme responsible for reactive oxygen species (ROS) production. As it turns out, the released ROS triggers cell death in the tissues, forming cavities for the passage of gases. The RBOH can also be activated by the presence of calcium (Ca2+) ions that are transported from the apoplast (water pathways). Certain plants have calcium-dependent protein kinases that use Ca2+ to add phosphates to the RBOH, stimulating it to produce ROS. This effect occurs at later stages as the plants gradually experience oxygen-deficient conditions after prolonged underwater submersion. While aerenchyma is mostly associated with plants that have adapted to soils with high water content, it can also develop in upland plants under drought and nutrient deficiency. Low concentrations of nitrogen and phosphorus, essential nutrients required for plant growth, was found to increase the ethylene sensitivity, stimulating the formation of aerenchyma. Moreover, ethylene was also a common factor in triggering aerenchyma in maize, offering a way to improve the crop's resilience. "The increase in ethylene sensitivity could be an effective strategy to stimulate aerenchyma formation in the absence of restricted gas diffusion," speculates Dr. Yamauchi. While the mechanism behind aerenchyma formation remains uncertain, suggesting the need for further research, the findings of this study open up the possibility of improving crop resilience and paving the way for better food security in the wake of climate change.

< Back INCT PlantStress results are presented in Symposium Between the 23th and 27th of July 2023, the Siconbiol - 17th Symposium on Biological Control and 2nd Latin American Symposium on Biological Control promoted by the Entomological Society of Brazil (SEB) took place in the cities of Juazeiro-BA and Petrolina - PE. Considered the largest event on biological control in Latin America, it brought together researchers, students, and professionals from the productive sector. The event addressed the latest advances in different areas of biological control, such as the use of bacteria, fungi, viruses, nematodes, parasitoids, predators and much more in the control of pests and diseases. Although the agricultural area is still the largest audience, the event also covers the health area, mainly with the increased use of biological control of medically important insects. Presentation of INCT PlantStress Biotech results During the event, one of the lectures was given by Dr. Carolina Morgante, who presented the results obtained by the research group of the Plant-Pest Interaction Laboratory (LIMPP) of Embrapa/Cenargen and which is linked to the INCT PlantStress. Dr Carolina showed important results that can be used in Integrated Pest Management (IPM) as cutting-edge tools for insect control. The use of genetic engineering, with genetic transformation techniques and RNAi technology are among the strategies used by researchers. Together with the productive sector, INCT PlantStress is always developing technologies for more profitable and sustainable agricultural production.

< Back Genetic engineering can have a positive effect on the climate Agriculture accounts for around 25 percent of all greenhouse gas emissions worldwide. A large share of these emissions is due to livestock production and fertilizer use. However, more than one-third of agriculture's emissions is caused by land-use change, especially the conversion of forests and other nature reserves to agricultural land in order to satisfy the rising global demand for food and feed. "Using better technologies to increase crop yields on the land already cultivated could reduce this land-use change and the associated emissions," says study author Prof. Dr. Matin Qaim, Director of the Center for Development Research at the University of Bonn. Certain types of genetically modified crops -- such as GM maize and soybean -- are widely grown in other parts of the world, but hardly in Europe. "The main reasons are public acceptance issues and political hurdles," says Qaim. In the new study, he and his colleagues from the Breakthrough Institute used global agricultural data and estimates of the yield effects of GM crops to model how increased technology adoption in the EU would affect production, land use, and greenhouse gas emissions. The estimates suggest that more widespread use of genetically modified crops in the EU could prevent the release of 33 million tons of CO2 equivalents, which corresponds to 7.5 percent of the EU's total annual greenhouse gas emissions from agriculture. Higher yields in the EU would have a global effect "Most of these positive climate effects are attributable to reduced land-use change," says Dr. Emma Kovak from the Breakthrough Institute, the study's first author. The conclusion of the research team: "The EU imports a lot of maize and soybean from Brazil, where the expansion of agricultural land contributes to tropical deforestation. Higher yields in the EU could reduce some of these imports and thus help preserve the Amazon rainforest." The authors stress that in their analysis they only look at already-existing genetically modified crops. "New genomic breeding technologies are currently being used to develop a wide range of new crop applications that could lead to additional climate change mitigation and adaptation benefits in the future," says Matin Qaim.

Identify and select in silico candidate genes related to drought tolerance of native species (wild peanuts, pitangueira, Clúsia, and cashew). Identify InDels and SNPs in candidate genes of native species associated with the drought response (wild peanuts, pitangueira, and cashew). Validate in vitro the expression profile of candidate genes for drought tolerance obtained in native species of Brazil (wild peanuts, pitangueira, Clúsia, and cashew). Sequencing using the Illumina platform a fraction of small RNAs, and their target mRNAs, and circular RNAs of plants (Arachis, Musa, soybean, pitangueira, and cashew tree) submitted to biotic and/or abiotic stresses. Analyze the sequencing data to check the methylation status of gene promoters in the metabolic pathways of interest. Validate the function of plant genes potentially involved in drought tolerance mechanisms in Arabidopsis, rice or sepia plants through strategies of overexpression or silencing. Organize, maintain and share an in vivo bank of the innovation assets obtained in the project shared by INCT members. Laboratory Description Research efforts in our laboratory are focused on the prospecting and characterization of genes involved in the response of plants to biotic and abiotic stresses. Emphasis: Soybean (Glycine max ), Jackbean (Canavalia ensiformis ) and Solanum nigrum . Approaches: Analysis of gene expression; Gene silencing; Overexpression; Subcellular location of gene products. For genetic transformation, we mainly use particle bombardment, but we are gaining experience in Agrobacterium -mediated transformation. Embryogenic tissues are used as targets for transformation.
