“…The decrease in chlorophyll content, porphyrins, and its precursors indicated that higher salt levels inhibited the de novo synthesis of chlorophyll and its precursors (Siddiqui et al, 2021 ). PsGPD expressing transgenic rice showed extremely low porphyrin precursors at 48 h, depicting the maximum conversion of precursors into porphyrin to generate chlorophyll molecules.…”

GPD encodes glyceraldehyde-3-phosphate dehydrogenase enzyme involved in sugar mobilization, particularly glycolysis and gluconeogenesis. The objective of this study was to determine physiological aspects of germination and early seedling establishment of PsGPD (Pleurotus sajor-caju glyceraldehyde-3-phosphate dehydrogenase) expressing transgenic rice (T5) against different salt concentrations. The T5 line that carried 2 copies of T-DNA and had the highest level of PsGPD expression was used in the investigation. Final germination percentage, amylase activity, reducing sugar accumulation, and chlorophyll biosynthesis were comparatively higher in PsGPD expressing transgenic rice against elevating saline conditions. A slow-paced conversion of porphyrin's precursors was seen through the matrix model and further elaborated by a graphical model. A sustained level of porphyrin was observed in PsGPD expressing transgenic rice. These data were concurrent with the relative gene expression and thermal imaging (thermography) of PsGPD expressing transgenic rice against salt stress. Morphological attributes also favored the salt tolerance exhibited by PsGPD-transformed rice.

“…In the last few decades, due attention has been paid to evaluating the effect of the pathogen on the overall rate of photosynthesis. Still, light harvesting efficiency has been neglected so far (Siddiqui et al, 2021). Photosynthesis is the specific physiological activity of green plants.…”

Microbial inoculants for controlling soil pathogens are an environmentally sustainable approach for attaining agricultural intensification. Charcoal root rot pathogens might threaten global food security and degrade prime agricultural lands. Microbial antagonists to control charcoal root disease were not properly studied with reference to physiological and photochemical basis. This research was aimed to examine the impact of newly isolated microbial biocontrol agents (MBCAs) on growth and photosynthetic efficiency (photosystem II) in pathogen (Macrophomina phaseolina)‐infected plants. The MBCAs (Purpureocillium lilacinum and Aspergillus terreus) were isolated and seeds were coated to improve soil fertility and resilience of agricultural lands. Both MBCAs inhibited the colonization of pathogenic fungus around the roots of host plants. Decline in growth traits was observed due to the detrimental impacts of root rot disease on growth parameters compared with plants treated with M. phaseolina. However, the growth of corn plants in both soils with and without M. phaseolina infestations was substantially improved by treating corn seeds with P. lilacinum and A. terreus. The pathogen drastically reduced the distinct parameters of photosystem II of photosynthesis. However, applying P. lilacinum and A. terreus significantly improved the total performance index (PItot), size, and the number of active reaction centers of photosystem II (Fv/Fo), electron transport rate, electron trapping per absorption (TRO/ABS), electron transport per absorption (ETO/ABS), electron transport per trapping (ETO/TRO), and the efficiency of light reaction (φEo) but downregulates nonphotochemical quenching (NPQ). Our study demonstrates that microbial antagonists offer a more effective, ecofriendly alternative to improve the land to sustainable agriculture.
