The rice RSS3 gene encoding a nucleoprotein. It with R/B homologous bHLH transcription factors regulating structure domain, for its root root elongation of the cell elongation and high salt regulation plays an important role.

Annotated Information

Function

This gene is called RICE SALT SENSITIVE3. It encodes a nucleoprotein, for its root root elongation of the cell elongation and high salt regulation plays an important role ^[1].

RSS3 to bHLH089 and bHLH094 interactions of transcription factors, also can and JAZ protein interactions, with bHLH094 JAZ9 ternary complex formation, and therefore, RSS3 - JAZ9 can inhibit bHLH094 mediated transcription activation.Rss3 mutant under exogenous JA missing, leading to cell elongation decreased, but does not affect the root of life.And known as JAs in addition to the common regulation of the root of the role of outside, also can regulate the expression of JA response genes, and maintained in the stress environment root cells play an important role in appropriate rate of elongation ^[1].

Mutant phenotype

Rss3 mutant root cell elongation is flawed, and the root of flexible variation.In the high salt environment, rss3 relatively wild type root growth severely damaged, in the high salt stress, root growth was moderate inhibition ^[1].

Expression

This gene is strongly expressed in the root, and especially the root tip ^[1].
