A dinâmica da comunidade bacteriana na rizosfera de genótipos de trigo, resistentes e suscetíveis ao fungo que causa a podridão das raízes (Bipolaris sorokiniana), foi avaliada ao longo de ciclos sucessivos de cultivo para identificar grupos bacterianos associados à supressão da doença em uma tese de doutorado. Conforme a doutoranda Mírian Rabelo de Faria, da Faculdade de Ciências Agronômicas da Unesp de Botucatu [...]

You might have observed plants competing for sunlight — the way they stretch upwards and outwards to block each other’s access to the sun’s rays — but out of sight, another type of competition is happening underground. In the same way that you might change the way you forage for free snacks in the break room when your colleagues are present, plants change their use of underground resources when they’re planted alongside other plants. In a paper published today in [...]

A study showing how pollen tubes grow into flowers to reach the ovule paves the way for the improvement of food crop varieties as well as a deeper understanding of the growth of fungi and neurons  A group of researchers from four countries, including Brazil, have worked out exactly how a pollen tube, the plant cell that emerges from a grain of pollen, grows up to a thousand-fold to reach an ovule deep inside the flower. The key to this growth is an inflow and outflow of protons that [...]

A Brazilian scientist has produced an inventory of 219 pathogens that infect plants in Brazil, including many agriculturally important species. The annotated list, published in Biota Neotropica, is the largest compilation of information on plant viruses ever produced in Brazil. It presents descriptions of the microorganisms, data on the diseases they cause, and information on their occurrence in native, cultivated and ornamental plants as well as weeds. “Since the start of my career, [...]

The largest database of plant viruses in Brazil serves as a tool for researchers, growers and policymakers A Brazilian scientist has produced an inventory of 219 pathogens that infect plants in Brazil, including many agriculturally important species. The annotated list, published in Biota Neotropica, is the largest compilation of information on plant viruses ever produced in Brazil. It presents descriptions of the microorganisms, data on the diseases they cause, and information on their [...]

Researchers affiliated with the Genomics for Climate Change Research Center (GCCRC), hosted by the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, have discovered a protein involved in corn's resistance to dry weather, high temperatures, and fungal invasion. This finding paves the way for the development of more drought-resistant plants and products that reduce losses in production at a time when global climate change threatens crop yields around the world. An [...]

Tornar a agricultura cada vez mais conectada é um dos principais desafios da pesquisa agropecuária. As tecnologias digitais são a grande aposta para a transformação da agricultura brasileira. Com base em conteúdo digital, tecnologia de ponta e conectividade, características da era digital, em breve as fazendas inteligentes integradas farão parte do dia a dia do produtor brasileiro. Pesquisas em inteligência artificial, aprendizado [...]

Available online for free, polyploid mapping system developed in Brazil helps breeders of sugarcane, kiwi, blueberry, sweet potato and forages, among other crops An innovative genetic mapping system for polyploid species promises to facilitate the work of scientists and plant breeders, who use genomics to develop varieties that are more productive and resistant to disease or drought. Polyploids are organisms with more than two sets of chromosomes. Many plant species of great economic value, [...]
