- Os02g0640500 <=> SIT1,OsSIT1
Function
- The rice (Oryza sativa) Salt Intolerance 1 (SIT1), a lectin receptor-like kinase expressed mainly in root epidermal cells, mediates salt sensitivity.
- NaCl rapidly activates SIT1, and in the presence of salt, as SIT1 kinase activity increased, plant survival decreased.
- Rice MPK3 and MPK6 function as the downstream effectors of SIT1.
- SIT1 phosphorylates MPK3 and 6, and their activation by salt requires SIT1. SIT1 mediates ethylene production and salt-induced ethylene signaling. SIT1 promotes accumulation of reactive oxygen species (ROS), leading to growth inhibition and plant death under salt stress, which occurred in an MPK3/6- and ethylene signaling-dependent manner in Arabidopsis thaliana.
- SIT1 and SIT2 each contribute to salt sensitivity and that their functions are not overlapping.
Expression
- SIT1 and SIT2 RNA expression was analyzed by quantitative RT-PCR in various tissues; the highest level of SIT1 and a relatively high level of SIT2 were detected in roots. SIT1 and SIT2 transcripts were mainly concentrated in the maturation zone, the region that produces lateral roots and root hairs.
- In RNAi plants, the transcript level of SIT1 was reduced more dramatically than that of SIT2. These results suggest that SIT1 is a major contributor to root function and is responsible for the RNAi phenotype.
