“…When there is high production of ROS the catalase (CAT) catalyse the dismutation of H 2 O 2 and convert it into H 2 O and O 2 in the cell mainly in peroxisomes and mitochondria and finishes the detoxification started by other enzymes (Kalisz et al, 2019).…”

Oxidative stress occurs in plant due to various environmental stressors like drought, high temperature, pathogen invasion, heavy metals, pesticides etc. when plant faces these conditions, reactive oxygen species (ROS) are produced in the chloroplast, mitochondria, plasma membrane, peroxisomes, ER and cell wall due to the leakage of electrons. Depending upon its concentration the role of ROS is decided if less then it will act as a signaling molecule but if in excess it will damage the cellular machinery of plants as the production of species like free radicals would take place. Though to combat these stress plants have antioxidant defense machinery which include enzymatic and non- enzymatic which lower down the level of ROS. Through genetic engineering more tolerant plants are produced which include modification of key genes like transcription factors. In this review article the molecular physiology of plants is discussed where in the factors contributing to stress including biotic and abiotic factors and various mitigation strategies.

“…Photosynthetic electron transport chains preferentially undergo cyclic and pseudocyclic electron transport and transfer electrons to O 2 to form O 2 − [ 18 ]. In addition, a high ROS content negatively affects plant growth, leading to oxidative damage of proteins and nucleic acids, as well as membrane lipid peroxidation [ 19 ]. Plants employ a series of antioxidant enzymes, such as superoxide dismutase (SOD, EC: 1.15.1.1) and peroxidase (POD), to eliminate excess ROS [ 20 ].…”

Chloroplasts are essential sites for plant photosynthesis, and the biogenesis of the photosynthetic complexes involves the interaction of nuclear genes and chloroplast genes. In this study, we identified a rice pale green leaf mutant, crs2. The crs2 mutant showed different degrees of low chlorophyll phenotypes at different growth stages, especially at the seedling stage. Fine mapping and DNA sequencing of crs2 revealed a single nucleotide substitution (G4120A) in the eighth exons of CRS2, causing a G-to-R mutation of the 229th amino acid of CRS2 (G229R). The results of complementation experiments confirmed that this single-base mutation in crs2 is responsible for the phenotype of the crs2 mutant. CRS2 encodes a chloroplast RNA splicing 2 protein localized in the chloroplast. Western blot results revealed an abnormality in the abundance of the photosynthesis-related protein in crs2. However, the mutation of CRS2 leads to the enhancement of antioxidant enzyme activity, which could reduce ROS levels. Meanwhile, with the release of Rubisco activity, the photosynthetic performance of crs2 was improved. In summary, the G229R mutation in CRS2 causes chloroplast protein abnormalities and affects photosystem performance in rice; the above findings facilitate the elucidation of the physiological mechanism of chloroplast proteins affecting photosynthesis.

“…Corn (Maize), a major food crop in many parts of the world [1], is the third most important food crop in China after wheat and rice [2]. Since corn is a warm-climate plant, chilling is one of the abiotic stimuli that influences its growth and development [3]. Therefore, effective measures to mitigate the damage caused by cold stress are crucial in corn production.…”

Breeding chilling-resistant corn coupled with the use of exogenous hormones to mitigate the damage caused by stress is important in successful corn farming. Here, we evaluated the germination rate of 45 corn varieties and profiled their chilling resistance level. Besides, to determine the effect of salicylic acid (SA) treatment on plants under cold stress, we treated the corn with SA and then selected chilling-resistant and chilling-sensitive varieties. Our data demonstrated that the germination energy (GE), germination percentage (GP), and germination index (GI) for most of the cold treated corn varieties were lower than those of the control group. The membership function (MF) and D-value results showed that HengYu709 was a chilling resistant corn variety while DongDan213 was sensitive to the chilling stimuli. Furthermore, treatment with SA enhanced the chilling resistance in both HengYu709 and DongDan213. In addition, the data showed that 0.5 or 1.0 mmol/l SA treatment significantly increased photosynthesis and oxidase activity in corn under cold stress. However, a high concentration of SA could reduce the photosynthesis indexes. Taken together, our data demonstrate that SA treatment could alleviate the effect of cold stress in corn growth and development.
