Annotated Information
Function
RSS1 ensures cell division activity under stress conditions[1].RSS1 affects SAM maintenance and abiotic stress responses[1].RSS1 contributes to maintenance of active cytokinin levels[1]. In the shoot, RSS1 contributes to the maintenance of the SAM size under stress conditions[1]. In agreement with the proposed function of RSS1, genes involved in the cell cycle and DNA replication were preferentially downregulated in rss1 under high-salt conditions. Conspicuously, more than 30% of the genes that were expressed specifically in the shoot apex were coordinately downregulated in rss1 under high-salt conditions , supporting the proposed function of RSS1 in maintaining proliferative tissue activity[1]. RSS1 functions preferentially in dividing cells, and its stability is regulated by cell cycle phase-dependent protein degradation through the aphase-promoting complex/cyclosome (APC/C)26S proteasome pathway. Moreover, RSS1 interacts with a type 1 protein phosphatase (PP1), which regulates many cellular processes, including the cell division cycle[2-6].
Expression
RSS1 mRNA is expressed abundantly in proliferating tissue, such as the basal region of the shoot, which contains apical and lateral shoot meristems and leaf primordia, and to a lesser extent, in the upper region of the shoot. RSS1 expression was upregulated by low temperatures, but not by high-salt conditions Supplementary[1].In the shoot apical meristem (SAM), RSS1 mRNA was detected only weakly in the central zone, where the cells are less active in terms of division and are completely undifferentiated[1].
Evolution
RSS1-related sequences are not only highly conserved among monocots, but can also be identified in basal angiosperms, including Amborella trichopoda, which belongs to the most ancient lineage of extant angiosperms (Fig. e)22. RSS1-related genes also exist in gymnosperms, ferns and mosses[1].
