“…The known intracellular systems responsible for disulfide reduction mainly include the thioredoxin (TRX) system and glutaredoxin (GRX) system, which were expressed as overdominance in the immature ears of hybrids in our study. The TRXs and GRXs are involved in multiple processes, such as protection of biomolecules from gamma irradiation (Yoon et al., 2013), modulation of redox‐dependent signalling cascades (J, 2003), CO 2 assimilation (Cheng et al., 2014), cell differentiation (Zheng et al., 2020), correct folding of proteins (Yuen et al., 2013), and carbon and nitrogen metabolism (Baumann & Juttner, 2002). Maintaining cell redox homeostasis is beneficial to cell division and growth (Aziz et al., 2017; Castellano & Sablowski, 2008).…”

Important traits related to maize (Zea mays L.) grain yield, such as kernel row number, ear length, kernel number per row, are determined during the development of female inflorescence. There is a significant positive correlation between yield component and the activity of inflorescence meristem (IM). To find the key stage of heterosis in the development of the ear, immature ears (from the IM stage until the end of the floral meristem [FM] stage) of Yudan888 and its parent lines were sampled to assay phenotype and for comparative transcriptomics analysis. The immature ear length of Yudan888 at the IM stage fitted an additive (mid-parental) model, but it showed high parental dominance at the spikelet-pair meristem (SPM) stage. Comparative analysis of transcriptomes suggested significant differences between additive and nonadditive expression patterns for different developmental stages. The number of distinct maternal or paternal genes (DMP) (genes expressed only in one parental line and their hybrid but silenced in another line) was greater than ABF1 (genes expressed in both parental lines but silenced in hybrid) at each stage. Gene Ontology (GO) enrichment suggested that the cell redox homeostasis genes with overdominance expression patterns in hybrids have an important contribution to heterosis. According to our research, an ear length heterosis network was established. The discovery of the inflection point for ear length heterosis allows us for inferring that the

“…Although algae play an important ecological role and are considered strong indicators of environmental changes, few studies have investigated their responses to ionizing radiation (De Micco et al 2011;Singh et al 2013;Yoon et al, 2013aYoon et al, , 2013bChoi et al, 2014;Mavi et al 2014). To our knowledge, there is no previous report on the response of an Arctic alga to ionizing radiation.…”

In this study, the effect of ionizing radiation on an Arctic alga was examined by assessing photosynthetic efficiency, antioxidant capacity, and proteomic changes. Arctic Zygnema sp. was gamma-irradiated at doses of 1, 3, and 5 kGy and showed serious cell damage after irradiation with the 5 kGy dose. The photosynthetic efficiency markedly decreased in gamma-irradiated Zygnema sp.; whereas, antioxidant capacity significantly increased. To investigate changes in protein expression levels, two-dimensional electrophoresis was performed. Thirty-nine protein spots were differently expressed. Several proteins, both upregulated and downregulated, were identified as photosynthesis-related proteins, confirming an important effect of gamma irradiation on the photosynthetic process. On the one hand, proteins similar to those involved in energy metabolism, isoprene biosynthesis, and protein biosynthesis were significantly downregulated. On the other hand, proteins related to DNA repair, quinone oxireductase, regulation of microtubules, and cell wall biogenesis were upregulated in gamma-irradiated Zygnema sp. These results provide insights on the effects of gamma irradiation on Zygnema sp. that can aid the interpretation of response mechanisms of Arctic algae to ionizing radiation.

“…Likewise, thioredoxin, found in almost every microorganism, has a key role in response to reactive oxygen species (ROS). For instance, its role in resistance of alga Spirogyra varians to gamma radiation has been reported ( 10 ).…”
