| 英文摘要 | Small heat shock proteins (sHSPs) are a class of molecular chaperones that bind to and prevent aggregation of proteins. To assess the potential role of sHSPs in protection against abiotic stresses, we conducted a screening of sHSP genes from the desiccation-tolerant resurrection plant Boea hygrometrica, which is widespread in East Asia in alkaline, calcium-rich limestone crevices. In total, 25 sHSP genes, belonging to six subgroups, were identified from the desiccated leaves of B. hygrometrica. Ten of these genes were cloned and named according to the nomenclature proposed for sHSPs. Transcripts of all these BhsHSPs were detectable in fresh leaves, but only 6 genes were induced after desiccation, and remained high during rehydration. Four of the cytosol-targeted BhsHSP genes were up-regulated under treatments, such as heat, cold, alkaline conditions, high calcium, oxidation, or application of the phytohormone abscisic acid. Together, these results demonstrate that CI and CII sHSPs, especially Bh17.9CI and Bh17.4BCII, are associated with abiotic stresses, and may function in the maintenance of protein stability, aiding in the adaptations to extreme environmental conditions in which B. hygrometrica can survive. |
