From: Characterization of ZmPMP3g function in drought tolerance of maize

The total root length of pot-grown maize. Analyses were conducted on the third day after the pot mix moisture was at the upper threshold of 40% for severe drought. Transgenic plants analyzed were from T4-generation lines. The data of transgenic line Z3-1 and wild type Z58 were not available. Each datum was the mean ± SD from root systems of 5 individual plants selected at random. The single asterisk (*) indicated a significant difference at p < 0.05. C7-2, Maize inbred line Chang7-2; C-7-2, C7-2 overexpressing ZmPMP3g; HZ4, Maize inbred line Huangzao4; H2-3, HZ4 overexpressing ZmPMP3g; SD, Standard deviation; T4, Transgenic generation 4; Y478, Maize inbred line Ye478; Y7-1, Y478 overexpressing ZmPMP3g; Z58, Maize inbred line Zheng58; Z3-1, Z58 overexpressing ZmPMP3g.
