Since their discovery as cell-division factors in plant tissue culture about five decades ago, cytokinins have been hypothesized to play a central role in the regulation of cell division and differentiation in plants. To test this hypothesis in planta, we isolated Arabidopsis plants lacking one, two, or three of the genes encoding a subfamily of histidine kinases (CRE1, AHK2, and AHK3) that fun...

Los abonos orgánicos aportan importantes beneficios al suelo y por consiguiente a las plantas lo que es importante evaluar sus efectos en los diferentes cultivos. En el presente estudio se evaluó efecto de siete dos niveles fertilización orgánica para variables altura planta, materia seca, extracción total nitrógeno, fósforo potasio maíz variedad Agroceres como planta indicadora condiciones inv...

Buscando compreender os efeitos do aumento da carga de gemas na demanda mão obra para o manejo videira, tem-se, com este trabalho, objetivo avaliar a eficiência práticas — como poda invernal, condução ramos, desfolha e colheita videira em função tempo despendido execução dessas práticas. O estudo foi realizado durante safra 2016/2017, um vinhedo comercial localizado no munícipio São Joaquim (SC...

Isoprene is the most abundant biogenic volatile hydrocarbon compound naturally emitted by plants and plays a major role in atmospheric chemistry. It has been proposed that isoprene synthases (IspS) may readily evolve from other terpene synthases, but this hypothesis has not been experimentally investigated. We isolated and functionally validated in Arabidopsis the first isoprene synthase gene, ...
