Abstract

In this experiment, physiological responses such as electrolyte leakage index (ELI) and relative expression of receptor-like kinase (RLK), ethylene response transcription factor (ERF) and vacuolar sorting receptor 6 (VSR-6) genes by Real-time PCR were studied in two genotypes of Chickpea (Cicer arietimun L. ) which are different in cold sensitivity (tolerant, Sel96Th11439 and sensitive, ILC533) during Cold stress (4° C) and TiO2 nanoparticles (NPs) (5 mg/l). The results showed that ELI content increased under Cold stress conditions in sensitive genotype compared to tolerant one, which indicated their genetic capacity to Cold stress. During Cold stress, TiO2 NPs caused a significant decrease in ELI, so that tolerant plants had lower ELI than sensitive ones. Therefore, the applied nanoparticles not only did not disturb the cell membrane under Cold stress but also are caused to decline of damages. During Cold stress, tolerant plants compared to sensitive ones, as well as in plants treated with TiO2 NPs compared to control plants showed significant increase in transcription levels of RLK, ERF and VSR-6 genes. An increase in expression of these genes is probably effective in the survival or recovery of plant because along with their increase, cell damages (ELI) resulted from reactive oxygen species (ROS) are decreased. Therefore, rapid and transient up-regulation of these genes particularly may be considered as functional markers in acclimation process in Chickpea against Cold stress. This finding that Chickpea plants treated with TiO2 show less damage and more relative expression of genes involving in cold tolerance may be establish new usage for nanoparticles and lead to the stable yield under stress in these plants.
