Physiological and transcriptome analysis of He-Ne laser pretreated wheat seedlings in response to drought stress

Abstract Drought stress is a serious problem worldwide that reduces crop productivity. The laser has been shown to play a positive physiological role in enhancing plant seedlings tolerance to various abiotic stresses. However, little information is available about the molecular mechanism of He-Ne la...
