Use of MfERF026 gene regulation in growth, development, and stress tolerance of Medicago sativa

Abstract

Provided is use of MfERF026 regulation in growth, development, and stress tolerance of Medicago sativa, which belongs to the technical field of plant genetic engineering. Provided is use of a regulatory agent for MfERF026, which is an ethylene responsive factor (ERF) in Medicago falcata, in promoting growth and development and improving drought tolerance and cold tolerance of M. sativa. The inhibited expression of MfERF026, the ERF in M. falcata may enhance the drought tolerance and cold tolerance of the M. sativa. Moreover, the inhibited expression of MfERF026, the ERF in M. falcata, may regulate the growth and development of M. sativa, thereby accelerating the growth rate of M. sativa to increase the number of leaves. The inhibited expression of MfERF026 provides a novel theoretical basis and a candidate gene for cultivating novel leguminous forage varieties with high resistance, yield, and protein content.
