<p>Leaves detached from WS and PLDδ-KO plants were treated with sterile water or 50 µM ABA for 5 days. Retardation of ABA-promoted senescence was compared between PLDδ-KO and WS leaves. <b>A.</b> Yellow coloration (top panel) or low Fv/Fm values for variable fluorescence (bottom panel) indicated the degree of senescence. The color bar at the bottom indicates Fv/Fm values. <b>B.</b> Effects of exogenous ABA on the chlorophyll content of leaves from WS and PLDδ-KO plants. FW, fresh weight. Values are means ± SDs (<i>n</i> = 5). <b>C.</b> Effects of exogenous ABA on cell death in leaves from WS and PLDδ-KO plants. Cell death was determined spectrophotometrically using Evan’s blue staining. Values are means ± SDs (<i>n = </i>5). Values with different letters are significantly different (<i>p</i><0.05). “*” indicates that the value is significantly different from that for WS under the same condition (<i>p</i><0.05).</p>
