Fig. 6From: The genome of a wild Medicago species provides insights into the tolerant mechanisms of legume forage to environmental stressProposed mechanisms behind tolerance of M. ruthenica to drought stress. The dotted lines represent the transfer and translation. Arrows denote positive effects, whereas lines ending with a short bar indicate negative effects. Photosynthetic rates were measured using the newly expanded leaves treated for 7 days by a gas exchange system (LI-COR 6800). Root samples at the seventh day of drought were used to determine H2O2 and proline. Asat photosynthetic rate, ROS reactive oxygen species, Mtr M. truncatula, XH Xinghe accession, and ZLQ Zhenglanqi accession. Data are means±SE (n=4). Different letters mean significant differences among treatments at P<0.05Back to article page
