Vascular transcription factors guide plant epidermal responses to limiting phosphate conditions

WRKY transcription factors in plant responses to stresses.

The WRKY gene family is among the largest families of transcription factors (TFs) in higher plants. By regulating the plant hormone signal transduction pathway, these TFs play critical roles in some plant processes in response to biotic and abiotic stress. Various bodies of research have demonstrated the important biological functions of WRKY TFs in plant response to different kinds of biotic a...

Ethylene and plant responses to phosphate deficiency

Phosphorus is an essential macronutrient for plant growth and development. Phosphate (Pi), the major form of phosphorus that plants take up through roots, however, is limited in most soils. To cope with Pi deficiency, plants activate an array of adaptive responses to reprioritize internal Pi use and enhance external Pi acquisition. These responses are modulated by sophisticated regulatory netwo...

Plant responses to nodulation factors.

The focus of research on signalling in Rhizobium-legume interactions has moved from understanding the structure and synthesis of rhizobially made Nod factors, towards an analysis of how they function in plants. Nod-factor-induced changes in ion fluxes across membranes, followed by establishment of an oscillation of intracellular Ca(2+) concentration, point to the involvement of a receptor-media...
