| Popis: | Within their natural habitat, plants are subjected to abiotic stresses that include heat stress. In the current study, the effect of 4 h, 24 h, and 48 h of heat stress on Tetraena propinqua ssp. migahidii seedling’s protein profile and proteomic analyses were investigated. Total soluble protein SDS-PAGE (Sodium dodecyl sulfate–polyacrylamide gel electrophoresis) profile showed 18-protein bands, the newly synthesized protein band (with molecular weights 86.5, 30.2 and 31.4 KD) at 24 h of heat stress and 48 of normal conditions. Proteomic analysis showed that 81 and 930 targets are involved in gene and protein expression respectively. At 4 h, 57 genes and 110 proteins in C4 reached 56 genes and 173 proteins in T4. At 24 h, 63 genes and 180 proteins in C24 decreased to 54 genes and 151 protein in T24. After 48 h, 56 genes and 136 proteins in C48 increased to 64 genes and 180 proteins in T48. The genes and proteins involved in transcription, translation, photosynthesis, transport, and other unknown metabolic processes, were differentially expressed under treatments of heat stress. These findings provide insights into the molecular mechanisms related to heat stress, in addition to its influence on the physiological traits of T. propinqua seedlings. Heat stress-mediated differential regulation genes indicate a role in the development and stress response of T. propinqua. The candidate dual-specificity genes and proteins identified in this study paves way for more molecular analysis of up-and-down-regulation. |
