What's a GeneRIF?

Data indicate that the transcript levels of sucrose transporters AtSUC2, AtSWEET11, AtSWEET12 and AtSWEET15 were significantly higher in stressed roots.
Title: Water Deficit Enhances C Export to the Roots in Arabidopsis thaliana Plants with Contribution of Sucrose Transporters in Both Shoot and Roots.
SWEET11, 12, and 15 exhibit specific spatiotemporal expression patterns in developing seeds. During later developmental stages, sucrose is mainly exported from the outer integument by SWEET15 and likely by SWEET11 from the inner integument. [SWEET15]
Title: A cascade of sequentially expressed sucrose transporters in the seed coat and endosperm provides nutrition for the Arabidopsis embryo.
The SAG29 protein may serve as a molecular link that integrates environmental stress responses into senescing process.
Title: An Arabidopsis senescence-associated protein SAG29 regulates cell viability under high salinity.
