El trabajo previo de nuestro laboratorio se caracterizó un programa genético activado en semillas por factores HSF, en el que juega un papel esencial el factor HaHSFA9, y que incluye la expresión de genes hsp. Este programa genético, al que denominamos ¿programa activado por HSFA9¿, está conservado en semillas de plantas como girasol (Almoguera...

HSFA9 is a seed-specific transcription factor that in sunflower (Helianthus annuus) is involved in desiccation tolerance and longevity. Here we show that the constitutive overexpression of HSFA9 in tobacco (Nicotiana tabacum) seedlings attenuated hypocotyl growth under darkness and accelerated the initial photosynthetic development. Plants...

Calcineurin B-like interacting protein kinases (CIPKs) decode calcium signals upon interaction with the calcium sensors calcineurin B like proteins into phosphorylation events that result into adaptation to environmental stresses. Few phosphorylation targets of CIPKs are known and therefore the molecular mechanisms underlying their downstream...
