Resumen:
Early in the plant defense response against pathogens, transcription of specific genes is activated. We
studied the genes up-regulated in the early resistance reaction of Phaseolus vulgaris against Colletotrichum
lindemuthianum. The effect of the light–dark transition, ultraviolet-(A–B) light, and temperature
stress on these genes was also evaluated. A calcium-binding protein and previously identified SUMO
genes were over-expressed in the plant reaction to pathogen and under environmental stress. These
genes appear to act as integrative signals and convergence points in early plant responses to pathogens
and several forms of environmental stress. The calcium-binding protein gene was present in both plant
and fungi genomes.
