Abstract

Abiotic stress leads to a change in the water content of plants. Salinity and osmotic stress affect both the morphology and physiology of plants. Plants have therefore responded to these environmental changes by adapting and tolerating them. The SABP2-interacting proteins (SIP) 428-silenced RNAi transgenic tobacco lines were subjected to various abiotic stresses (salinity, osmotic, and drought). The effect of SIP428-silencing on the tobacco plants subjected to these abiotic stresses was monitored. The results from the root growth data show that the sip428-silenced lines exhibit enhanced tolerance to the stressors compared to the wild-type plants. Interestingly, results of the relative chlorophyll content show no significant difference between the wild-type plants and sip428-silenced transgenic plants. In summary, based on the results presented in this study it could be concluded that SIP428 is a negative regulator of salinity, osmotic and drought stresses. Further studies are required to understand the mechanism.
