“…Carbon metabolism is an important process re ecting the physiological status and metabolism of plants 30 , and exploring the in uence of parents on carbon metabolism of offspring is one of the important ways to achieve high yield of sorghum 31,32 .RuBP carboxylase, sucrose synthase, sucrose phosphate synthase, and PEP carboxylase, as key enzymes of the photosynthetic pathway of the plant, in uence the uptake and utilization of carbon by the plant, and at the same time, RuBP carboxylase is a bifunctional enzyme that regulates the xation of CO 2 and is also involved in the regulation of the photorespiratory pathway 33,34,35 . Yuan et al 36 found that in wheat, the activity of RuBP carboxylase in the F1 generation of hybrids was higher than that of the maintained lines but lower than that of the sterile lines at the seedling and owering stages, whereas at the nodulation stage, RuBP carboxylase activity did not show any difference among the materials.…”

Heterosis plays an important role in improving crop yield. Understanding the expression of heterosis for photosynthetic physiological traits in sorghum is important for breeding sorghum varieties with strong hybrid dominance. In this study, six sorghum restorer lines and six sorghum sterile lines and their thirty-six hybrid combinations formulated according to the NCII incomplete double-row hybridization method were used as materials, and the performance of hybrids in the F1 generation of hybrids in terms of hybridization in leaf photosynthesis-related parameters and carbon metabolism-related enzymes and their correlation with yield traits were analyzed at the flowering stage. The results showed that net photosynthetic rate (Pn), transpiration rate (Tr), stomatal conductance (Gs), apparent leaf meat conductance (AMC), ribulose-1,5-bisphosphate (RuBP) carboxylase, phosphoenolpyruvate (PEP) carboxylase, and sucrose phosphate synthase (SPS) of hybrid sorghum showed significant high-parent heterosis, while inter-cellular carbon dioxide concentration (Ci), water use efficiency (WUE), and sucrose synthase (SuSy) mainly showed negative heterosis, a few showed high-parent heterosis. Thousand grain weight (TGW), grain weight per spike (GWPS) and dry matter content (DMC) all showed high high-parent heterosis, with the highest value of 82.54% for thousand grain weight (TGW). Meanwhile, Pn was positively correlated with Tr, Ci, Gs, RuBP carboxylase, PEP carboxylase, GWPS, TGW, and DMC, which indicated that Tr, Ci, and Gs could assist in the screening of high-photosynthesis sorghum varieties and that Pn could assist in the screening of carbon-efficient sorghum varieties, and that Pn was closely related to yield. In summary, the F1 generation of sorghum hybrids has shown significant heterosis at anthesis. Combined with the field performance, the Pn at anthesis can be used as a reference for early prediction of the yield potential of the F1 generation of sorghum hybrids and screening of carbon-efficient sorghum varieties.

“…SA regulate plant development; it protects plants from environmental stress like salt stress [ 19 ]. High agricultural yields can be achieved by applying SA, which improves plant growth and germination rates in both salt- and stress-free conditions [ 20 ]. It has been determined that applying salicylic acid can have an impact on seed production, stomatal regulation, chlorophyll content, and photosynthesis [ 21 ].…”

Barley (Hordeum vulgare L.) is a significant cereal crop belonging to Poaceae that is essential for human food and animal feeding. The production of barley grains was around 142.37 million tons in 2017/2018. However, the growth of barley was influenced by salinity which was enhanced by applying a foliar spray of salicylic acid. The current study investigated to evaluated the potential effect of SA on the barley (Hordeum vulgare L.) plants under salinity stress and its possible effects on physiological, biochemical, and growth responses. The experiment was conducted at Postgraduate Research Station (PARS), University of Agriculture; Faisalabad to assess the influence of salicylic acid on barley (Hordeum vulgare L.) under highly saline conditions. The experiment was conducted in a Completely Randomized Design (CRD) with 3 replicates. In plastic pots containing 8 kg of properly cleaned sand, two different types of barley (Sultan and Jau-17) were planted. The plants were then watered with a half-strength solution of Hoagland’s nutritional solution. After the establishment of seedlings, two salt treatments (0 mM and 120 mM NaCl) were applied in combining three levels of exogenously applied salicylic acid (SA) (0, 0.5, and 1 mg L-1). Data about morphological, physiological, and biochemical attributes was recorded using standard procedure after three weeks of treatment. The morpho-physiological fresh weight of the shoot and root (48%), the dry mass of the shoot and root (66%), the plant height (18%), the chlorophyll a (30%), the chlorophyll b (22%), and the carotenoids (22%), all showed significant decreases. Salinity also decreased yield parameters and the chl. ratio (both at 29% and 26% of the total chl. leaf area index). Compared to the control parameters, the following data was recorded under salt stress: spike length, number of spikes, number of spikelets, number of tillers, biological yield, and harvest index. Salicylic acid was used as a foliar spray to lessen the effects of salinity stress, and 1 mg L-1 of salicylic acid proved more effective than 0.5 mg L-1. Both varieties show better growth by applying salicylic acid (0 mg L-1) as a control, showing normal growth. By increasing its level to (0.5 mg L-1), it shows better growth but maximized growth occurred at a higher level (1 mg L-1). Barley sultan (Hordeum vulgare L.) is the best variety as compared to Jau-17 performs more growth to mitigate salt stress (0mM and 120mM NaCl) by improving morpho-physiological parameters by enhancing plan height, Root and shoot fresh and dry weights, as well as root and shoot lengths, photosynthetic pigments, area of the leaves and their index, and yield attributes and reduce sodium ions.

“…In hyssop ( Hyssopus officinalis ) plants, phenols and anthocyanins are significantly increased upon salt stress treatment [ 35 ]. SA- and MeJA-pretreated sorghum ( Sorghum bicolor ) plants show substantial decreases in ROS accumulation under salt stress [ 36 , 37 ]. Excess salt leads to an increase in the content of ABA in rice [ 38 ].…”

Caffeic acid O-methyltransferase (COMT) participates in various physiological activities in plants, such as positive responses to abiotic stresses and the signal transduction of phytohormones. In this study, 18 COMT genes were identified in the chromosome-level reference genome of mango, named MiCOMTs. A phylogenetic tree containing nine groups (I-IX) was constructed based on the amino acid sequences of the 71 COMT proteins from seven species. The phylogenetic tree indicated that the members of the MiCOMTs could be divided into four groups. Quantitative real-time PCR showed that all MiCOMT genes have particularly high expression levels during flowering. The expression levels of MiCOMTs were different under abiotic and biotic stresses, including salt and stimulated drought stresses, ABA and SA treatment, as well as Xanthomonas campestris pv. mangiferaeindicae and Colletotrichum gloeosporioides infection, respectively. Among them, the expression level of MiCOMT1 was significantly up-regulated at 6–72 h after salt and stimulated drought stresses. The results of gene function analysis via the transient overexpression of the MiCOMT1 gene in Nicotiana benthamiana showed that the MiCOMT1 gene can promote the accumulation of ABA and MeJA, and improve the salt tolerance of mango. These results are beneficial to future researchers aiming to understand the biological functions and molecular mechanisms of MiCOMT genes.
