Proteins differentially-accumulated and identified by MALDI-TOF-TOF MS in <i>Populus</i> × <i>canadensis</i> Moench seeds under controlled aging treatment at 30°C and 75% relative humidity for 0, 45 and 90 d.

<p>Only protein spots that changed in abundance at least 1.5-fold (<i>P</i> < 0.05) of three replicates are included. Some fold changes are between –1.5 and +1.5, because there is a change of at least 1.5-fold in one of the other treatments. The positions of the spots are shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0132509#pone.0132509.g002" target="_blank">Fig 2</a>. Exp. protein mass, experimental protein mass; Theo. protein mass, theoretical protein mass. 0, 45 and 90 d, seeds controlled deteriorated at 30°C and 75% relative humidity for 0, 45 and 90 d, respectively; A, appeared; D, disappeared; NA, undetected in both treatments. +, increased;–, decreased. * Blasted from other species.
