“…Throughout their maturation process, the enzymatic systems for antioxidant defense are rearranged so that seeds can tolerate intense attacks of reactive oxygen species during desiccation. The same does not happen to recalcitrant seeds, as in ingá, and to the immature orthodox ones (Bailly, 2004 and references within;Chen et al, 2018;Dussert et al, 2018). Therefore, the difference between the metabolic state of ingá seeds in an incomplete maturation process (still without a fully developed antioxidant system) and that of bean seeds (with complete and operant systems) was once again evidenced (Barbedo et al, 2013;.…”

Inga vera ssp. affinis embryos at different maturity stages and with various water contents had their CO2 production and O2 consumption analyzed, and then compared to those of Phaseolus vulgaris L. seeds. The results showed that the lower the temperature, the lower the respiratory rates and the more intense the other oxidative processes of I. vera embryos. On the other hand, the same did not happen in P. vulgaris seeds. Oxidative reactions, including respiration, reduced the germinative capacity and compromised the preservation of the embryos and seeds. Oxidative reactions depended on the embryo maturity stage, its moisture level, and the surrounding temperature. Interestingly, the responses obtained for viability loss and changes in O2 consumption rates of I. vera embryos did not correspond to the expected for plant tissues, as verified in P. vulgaris seeds with similar water content.

“…Ma et al (2014) found that the contents of HSP101 and HSP17.2 were increased from 7 to 28 DAP in wheat seeds. Chen et al (2018) showed that the abundance of two HSPs increased from 20 to 38 DAP in wheat seeds. Consistent with this, we found that eight HSPs were more abundant during the PDP cp .…”

The enrichment of Em6, PM18, PM25, EMB564 and other proteins belonging to the LEA protein family and several HSPs has been detected during cereal seed dehydration (Chatelain et al, 2012;Huang, Møller, & Song, 2012).…”

“…Proteomic analyses are useful for studying the proteins participating in biological processes in plants (Kamal & Komatsu, 2016;Staudinger et al, 2016), and many defense-related proteins have been identified as differentially expressed during the grain dehydration process. Chen et al (2018) found that the proteins involved in starch and sucrose metabolic and defense/stress responses showed the greatest differences in abundance during wheat seed development. Previous results also showed that the expression of proteins related to dehydration tolerance and seed development was significantly altered during kernel maturation (Goldberg, Barker, & Perez-Grau, 1989;Hughes & Galau, 1989;Rosenberg & Rinne, 1986;Skriver & Mundy, 1990).…”

Enhanced defense ability facilitates the water loss of maize kernels during physiological dehydration

et al. 2020

The kernel water concentration (KWC) varies more intensely during the physiological dehydration phase, and the dehydration process during this phase has been demonstrated to be closely associated with internal physiological processes in maize kernels. To better illustrate the physiological dehydration process (PDP) of maize kernels, moisture characteristic parameters were consecutively recorded after pollination, and the timing of the occurrence of net water loss was confirmed. Additionally, a tandem mass tag (TMT) based proteomic analysis was performed to identify the significantly differentially expressed proteins during the critical period of the PDP (PDP cp). The results showed that maize varieties presented significant variance in the KWC, kernel water content, dry-down rate (DR) and absolute DR; nevertheless, the KWC was similar (below 65%) when net water loss occurred. In addition, 20-28 days after pollination was indicated to be the PDP cp in this study. Based on proteome analysis, Yuyu 30 and Suyu 41 showed 163 and 132 differentially expressed proteins (DEPs), respectively during the PDP cp and 99 DEPs overlapped between the varieties. During the PDP cp , the desiccation tolerance, antioxidation capability, detoxification and other stress response abilities of maize kernels were significantly increased. The increased defense abilities enabled the maize kernels to establish coordinated, diverse, stable defense mechanisms that accelerated water loss from maize kernels during the PDP cp .
