Overexpression of

Herbicides are the major tool for controlling large populations of yield depleting weeds. However, over-reliance on herbicides has resulted in weed adaptation and herbicide resistance. In recent years, early flowering species related to resistance is emerging, which may cause seed loss before crop harvest, creating a new problem non-chemical management. this study, homologue gene AGAMOUS sub-family (referred as PfAG5) MADS-box family was cloned from plants an Polypogon fugax Nees ex Steud. population resistant ACCase inhibitor (clodinafop-propargyl). The PfAG5 functionally characterised Arabidopsis thaliana L. Overexpression flowering, abnormal flowers (e.g. small petals), short reduced set, compared with wild type. expression high leaves flowers, but low pods transgenic Arabidopsis. expressed earlier higher (R) than susceptible (S) P. plants. Furthermore, one protein (FRIGIDA-like) relevance time regulation interacts identified by yeast two-hybrid pull-down assays. These results suggest that involved modulating fugax.
