Light stress-regulated two-helix proteins in Arabidopsis thaliana related to the chlorophyll a/b-binding gene family.

ABSTRACT: The chlorophyll a/b, chlorophyll a/c, and chlorophyll a/a light-harvesting proteins are part of an extended gene family that also includes the transiently expressed stress proteins, the Elips (early light-induced proteins). Four Elip homologue proteins, encoded by single-copy nuclear genes, have been identified in the Arabidopsis thaliana database. These proteins were divided into two groups according to the expression pattern under light-stress conditions and the predicted secondary structure. Group one included two members of the Elip family with three predicted transmembrane helices and a gene expression strictly related to light stress. Group two included two proteins, the Seps (stress-enhanced proteins), which possessed two predicted transmembrane segments. The transcripts of Sep1 and
