Abstract:
BACKGROUND: Acyl-CoA-Binding proteins (ACBPs) function as coenzyme A transporters and play important roles in regulating plant growth and development in response to abiotic stress and phytohormones, as well as in membrane repair. To date, the ACBP family has not been a comprehensively characterized in barley (Hordeum vulgare L.).
RESULTS: Eight ACBP genes were identified in the barley genome and named as HvACBP1-8. The analysis of the proteins structure and promoter elements of HvACBP suggested its potential functions in plant growth, development, and stress response. These HvACBPs are expressed in specific tissues and organs following induction by abiotic stressors such as drought, salinity, UV-B exposure, temperature extremes, and exposure to exogenous phytohormones. The HvACBP7 and HvACBP8 amino acid sequences were conserved during the domestication of Tibetan Qingke barley.
CONCLUSIONS: Acyl-CoA-binding proteins may play important roles in barley growth and environmental adaptation. This study provides foundation for further analyses of the biological functions of HvACBPs in the barley stress response.
摘要:
背景:酰基辅酶A结合蛋白(ACBP)作为辅酶A转运蛋白,在调节植物生长和发育以应对非生物胁迫和植物激素方面发挥重要作用,以及在膜修复。迄今为止,ACBP家族在大麦(大麦)中尚未得到全面表征。
结果:在大麦基因组中鉴定出8个ACBP基因,命名为HvACBP1-8。对HvACBP的蛋白质结构和启动子元件的分析表明其在植物生长中的潜在功能。发展,和应激反应。这些HvACBPs在非生物胁迫如干旱诱导后,在特定的组织和器官中表达。盐度,UV-B暴露,极端温度,和暴露于外源植物激素。HvACBP7和HvACBP8氨基酸序列在西藏青克大麦驯化过程中保守。
结论:酰基辅酶A结合蛋白可能在大麦生长和环境适应中起重要作用。本研究为进一步分析HvACBPs在大麦应激反应中的生物学功能奠定了基础。
