RT   "A desiccation-related Elip-like gene from the resurrection plant
RT   Craterostigma plantagineum is regulated by light and ABA.";
RL   EMBO J. 11:2771-2778(1992).
CC   -!- FUNCTION: Possibly exerts a protective role during water loss.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane; Multi-
CC       pass membrane protein.
CC   -!- TISSUE SPECIFICITY: Preferentially localized in the chloroplast-rich
CC       palisade parenchyma cells, in extracts of desiccated leaves, in seeds,
CC       but not in roots or untreated leaves.
CC   -!- INDUCTION: By light, ABA and desiccation.
CC   -!- SIMILARITY: Belongs to the ELIP/psbS family. {ECO:0000305}.
