Proline, as an osmolyte , plays a crucial role in plants during adaption to various types of environmental stresses. Eremochloa ophiuroides is a main warm-seasonal turf-forming turfgrass due to its strong drought resistance. The paper mainly studied the probably pathway of proline accumulation in five-leaf-stage seedlings of Eremochloa ophiuroides under water stress (20% PEG6000 treatment and natural water loss), explored the effect of exogenous ABA and CaCl2 on proline accumulation , aiming to ...
