内蒙古大学科研团队找到 紫花苜蓿抗旱增产“基因开关”

Core Insights - The research team led by Professor Niu Yiding from Inner Mongolia University has made significant breakthroughs in studying drought resistance and growth regulation mechanisms in alfalfa, identifying a key gene, ERF026, which acts as a "molecular switch" to address the dilemma of growth versus survival under drought conditions [1][2] Group 1: Research Findings - The ERF026 gene belongs to the AP2/ERF transcription factor family and is revealed to be a crucial link between jasmonic acid signaling pathways and plant growth and development [1] - Suppressing the expression of the ERF026 gene allows for increased biomass under normal conditions by reducing jasmonic acid synthesis, while also enabling plants to switch to a "defense mode" during drought, enhancing water use efficiency and antioxidant enzyme activity [2] Group 2: Application Prospects - The findings have significant application potential, as gene editing technology could be used to precisely regulate ERF026, leading to the development of high-yield, drought-resistant alfalfa varieties suitable for arid regions [2] - This advancement is expected to contribute to the safety of livestock feed in China and positively impact ecological restoration and soil conservation in drought-prone areas [2]
