Arabidopsis cold shock domain proteins: relationships to floral and silique development.

ABSTRACT: Cold shock domain proteins (CSPs) are highly conserved from bacteria to higher plants and animals. Bacterial cold shock proteins function as RNA chaperones by destabilizing RNA secondary structures and promoting translation as an adaptative mechanism to low temperature stress. In animals, cold shock domain proteins exhibit broad functions related to growth and development. In order to understand better the function of CSPs in planta, detailed analyses were performed for Arabidopsis thaliana CSPs (AtCSPs) on the transcript and protein levels using an extensive series of tissue harvested throughout developmental stages within the entire life cycle of Arabidopsis. On both the transcript and protein levels, AtCSPs were enriched in shoot apical meristems and siliques. Although all AtCSPs exhibi
