Cultivated peanut (A. hypogaea L. is a very important tropical oilseed, valued both for subsistence and as a cash crop. It is an allotetraploid of recent origin with an AB type genome (2n = 4x = 40) and has very low DNA polymorphism, a characteristic that has ha...

South America includes some mega-diverse countries, but genetic resources locally used for food and agriculture are mostly of exotic origin. Exclusively exotic crops, with no local germplasm, sometimes are key elements behind successful agribusiness. The local importance of coffee, soybeans, suga...

Brazilian forage breeding programs are below the needs for a country of continental dimensions. They target too few species, and grass cultivars are mostly exotic. The main forage cultivars resulted of phenotypic selection based on agronomic merit, and, just a short time ago, this&...

The objective of this study was to obtain cowpea plants carrying an expression cassette seed-specific to a gene of a protein rich in methionine residues. To achieve this, we constructed an expression vector bearing a methionine-rich delta-zein gene from maize under the control alph...

Gliricidia sepium is a tree species native to the Americas that has been disseminated throughout various regions of the world due to its drought adaptability. In response to the productive sector's demand for the development of cultivars, Empresa Brasileira de Pesquisa Agropecuária ...

In this study proteomics provides a broad view of cassava varieties at the level of proteins. It is intended to give an understanding of the technologies behind proteomics and its application to address biological questions regarding source-flux-sink interactions, high starch accumulation, n...

A research program at EMBRAPA Genetic Resources and Biotechnology exploits natural genetic variation to overcome genetic bottlenecks during domestication and to improve yield and quality of cassava storage root. Here, we integrate results genetic diversity, metabolite profiles (carotenoid synthesis), ...

Advances in computational design have greatly accelerated antimicrobial peptide engineering. In this study, three Plasmodium chabaudi-derived peptides (PcDBS1R1, PcDBS1R5, and PcDBS1R9), generated using the Joker computational design algorithm, were synthesized and characterized for their structural and functional&#...

Accurate estrus detection in grazing crossbred dairy cows (Zebu × Taurine) remains challenging in Brazil, and automated activity monitoring (AAM) systems may be a viable alternative. This study evaluated the effects of management and environmental factors on AAM performance for estrus detection i...
