From: Characterization of ZmPMP3g function in drought tolerance of maize
Leaf wilting index (a), leaf RWC (b), and LWP (c) of pot-grown maize. Analyses were conducted on the second day after the pot mix moisture was at the upper threshold of 50% for moderate drought and 40% for severe drought, respectively. Transgenic plants analyzed were from T4-generation lines. The leaf wilting index for each line under each treatment was calculated based on all leaves of 5 individual plants selected at random. The RWC and LWP were analzyed by using the second fully-expanded leaves down from the top of 3 individual plants selected at random under moderate drought and presented as the mean ± SD. The single asterisk (*) and double asterisk (**) indicated significant differences at p < 0.05 and p < 0.01, respectively. C7-2, Maize inbred line Chang7-2; C-7-2, C7-2 overexpressing ZmPMP3g; HZ4, Maize inbred line Huangzao4; H2-3, HZ4 overexpressing ZmPMP3g; LWP, Leaf water potential; RWC, Relative water content; SD, Standard deviation; T4, Transgenic generation 4; Y478, Maize inbred line Ye478; Y7-1, Y478 overexpressing ZmPMP3g; Z58, Maize inbred line Z58; Z3-1, Z58 overexpressing ZmPMP3g.
