Three OsMYB36 members redundantly regulate Casparian strip formation at the root endodermis.

Plants have evolved a lignin-based Casparian strip (CS) in roots that restricts passive diffusion of mineral elements from the soil to the stele. However, the molecular mechanisms underlying CS formation in rice (Oryza sativa), which contains a CS at both the exodermis and endodermis, are poorly understood. Here, we demonstrate that CS formation at the rice endodermis is redundantly regulated by three MYELOBLASTOSIS (MYB) transcription factors, OsMYB36a, OsMYB36b, and OsMYB36c, that are highly expressed in root tips.

A NAC transcription factor OsNAC3 positively regulates ABA response and salt tolerance in rice.

Background: NAC (NAM, ATAF and CUC) transcription factors (TFs) play vital roles in plant development and abiotic stress tolerance. Salt stress is one of the most limiting factors for rice growth and production. However, the mechanism underlying salt tolerance in rice is still poorly understood.

Overexpression of Improves Calcium Tolerance in Rice.

The Casparian strip domain protein 1 () is necessary for the formation of the Casparian strip (CS) in the rice endodermis. It also controls Ca transport to the stele. Here, we demonstrated that overexpression enhanced Ca tolerance in rice.

Overexpression of Inhibits the Growth of Rice and Causes Spontaneous Cell Death.

The Mediator complex transduces information from the DNA-bound transcription factors to the RNA polymerase II transcriptional machinery. Research on plant Mediator subunits has primarily been performed in Arabidopsis, while very few of them have been functionally characterized in rice. In this study, the rice Mediator subunit 16, was examined.
