Abstract
It is proven that retrograde tetrapyrrole-induced plastid signals, light signals, and signals induced by hormones and carbohydrates influence expression of nuclear genes of plastid stress proteins ELIP in Arabidopsis thaliana L. Plastid signals differently regulated expression of genes from multigene family of photosynthesis proteins (ELIP and Lhcb2) and were modulated by light. The influence of a regulator of plant growth--abscisic acid--led to activation of expression of ELIP genes in the light. Carbohydrates suppressed transcription of ELIP genes. Thus, signals of exogenous (light) and endogenous (retrograde signals, hormones, carbohydrates) origin influence the expression of ELIP genes. These types of signals probably interact with each other and favor the increase of resistance of plants to the action of stress factors of the environment.
