Total lipids in leaves of WS and PLDδ-KO plants during detachment-induced and ABA-promoted senescence.

The relative change (RC) in the levels of lipids from 0 to 5 days is the percentage value for the significant difference between the values at day 0 and 5 days over the value at day 0. Values in the same row with different letters are significantly different (P<0.05). “*” indicates that the value is significantly different from that of the WS under the same condition (p<0.05). Values are means ± SDs (n = 5).
