Male sterility (MS) plays a key role in the hybrid breed production of plants. Researchers have focused on the association between genetic male sterility (GMS) and cytoplasmic male sterility (CMS) in kenaf. In this study, P9BS (a natural GMS mutant of the kenaf line P9B) and male plants of P9B were used as parents in multiple backcross generations to produce P9SA, a CMS line with stable sterility, to explore the molecular mechanisms of the association between GMS and CMS. The anthers of the maintainer (P9B), GMS (P9BS), and CMS (P9SA) lines were compared through phenotypic, cell morphological, physiological, biochemical observations, and transcriptome analysis. Premature degradation of the tapetum was observed at the mononuclear stage in P9BS and P9SA, which also had lower activity of reactive oxygen species (ROS) scavenging enzymes compared with P9B. Many coexpressed differentially expressed genes were related to ROS balance, including ATP synthase, electron chain transfer, and ROS scavenging processes were upregulated in P9B. CMS plants had a higher ROS accumulation than GMS plants. The MDA content in P9SA was 3.2 times that of P9BS, and therefore, a higher degree of abortion occurred in P9SA, which may indicate that the conversion between CMS and GMS is related to intracellular ROS accumulation. Our study adds new insights into the natural transformation of GMS and CMS in plants in general and kenaf in particular.

Relationship Of

The phenomenon of oxidative stress, characterized as an imbalance in the production of reactive oxygen species and antioxidant responses, is a well-known inflammatory mechanism and constitutes an important cellular process. The relationship of viral infections, reactive species production, oxidative stress, and the antiviral response is relevant. Therefore, the aim of this review is to report studies showing how reactive oxygen species may positively or negatively affect the pathophysiology of viral infection. We focus on known respiratory viral infections, especially severe acute respiratory syndrome coronaviruses (SARS-CoVs), in an attempt to provide important information on the challenges posed by the current COVID-19 pandemic. Because antiviral therapies for severe acute respiratory syndrome coronaviruses (e.g., SARS-CoV-2) are rare, knowledge about relevant antioxidant compounds and oxidative pathways may be important for understanding viral pathogenesis and identifying possible therapeutic targets.

Ba, Q. S., Zhang, G. S., Wang, J. S., Che, H. X., Liu, H. Z., Niu, N., Ma, S. C. and Wang, J. W. 2013. Relationship between metabolism of reactive oxygen species and chemically induced male sterility in wheat (Triticum aestivum L.). Can. J. Plant Sci. 93: 675–681. Chemically induced male sterility (CIMS) systems in wheat are among the male sterility types used for hybrid wheat (Triticum aestivum L.) production in China. Some studies suggested that male sterile line Xi'nong 1376-CIMS induced by chemical hybridizing agents (CHA) may suffer from oxidative stress as its cyanide-resistant respiration is lower than that of Xi'nong1376. To elucidate the metabolic mechanism of reactive oxygen species (ROS) in the CIMS anthers, the metabolism changes in the production and scavenging of ROS and gene expression related to ROS-scavenging enzymes were investigated in the anther of Xi'nong 1376-CIMS and Xi'nong1376.Anthers of Xi'nong 1376-CIMS had higher contents of [Formula: see text] and H2O2 than those of 1376, which corresponds to expression level of the NADPH oxidase (NOX) gene, and has higher contents of malondialdehyde compared with 1376. Simultaneously, there were lower activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and ascrodate peroxidase (APX) in scavenging ROS in the anthers of the Xi'nong 1376-CIMS line than in Xi'nong1376. Meanwhile, the expressions of SOD, POD, CAT and APX genes in 1376 were always higher at different levels than those in the Xi'nong 1376-CIMS line except for POD in stage 1. Therefore, it is possible that the sterility in Xi'nong 1376-CIMS is related to the abortion of microspores induced by chronic oxidative stress caused by an abnormal increase in ROS.
