Steroid hormones alter dendritic architecture in many animals, but the exact relationship between dendritic anatomy, synaptic strength, and behavioral expression is typically unknown. In larvae of the moth Manduca sexta, the tip of each abdominal proleg (locomotory appendage) bears an array of mechanosensory hairs, each innervated by a planta hair sensory neuron (PH-SN). In the CNS, PH-SN axons...

Non-cellulosic cell wall polysaccharides constitute approximately one quarter of usable biomass for human exploitation. In contrast to cellulose, these components are usually substituted by O-acetyl groups, which affect their properties and interactions with other polymers, thus affecting their solubility and extractability. However, details of these interactions are still largely obscure. More...

HopQ1 (for Hrp outer protein Q), a type III effector secreted by Pseudomonas syringae pv phaseolicola, is widely conserved among diverse genera of plant bacteria. It promotes the development of halo blight in common bean (Phaseolus vulgaris). However, when this same effector is injected into Nicotiana benthamiana cells, it is recognized by the immune system and prevents infection. Although the ...

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...
