Generating new strategies to improve plant performance and yield in crop plants becomes increasingly relevant with ongoing and predicted global climate changes. E3 ligases that function as key regulators within the ubiquitin proteasome pathway often are involved in abiotic stress responses, development, and metabolism in plants. The aim of this research was to transiently downregulate an E3 ligase that uses BTB/POZ-MATH proteins as substrate adaptors in a tissue-specific manner. Interfering with the E3 ligase at the seedling stage and in developing seeds results in increased salt-stress tolerance and elevated fatty acid levels, respectively. This novel approach can help to improve specific traits in crop plants to maintain sustainable agriculture.
随着当前和预测的全球气候变化，制定新策略以提高作物的性能和产量变得越来越重要。作为泛素蛋白酶体途径关键调节因子的E3连接酶，通常参与植物的非生物胁迫反应、发育和代谢。本研究的目的是以组织特异性方式瞬时下调一种以BTB/POZ-MATH蛋白为底物衔接子的E3连接酶。在幼苗期和发育中的种子中干扰该E3连接酶，分别导致盐胁迫耐受性增加和脂肪酸水平升高。这种新方法有助于改善作物的特定性状，以维持可持续农业。
