“…This reduction in seed yield in OTC plants was due to fewer grains per panicle, which was compensated by the presence of more panicles to an extent. Similar studies were carried out by Jena et al. (2018) in rice and Prasad et al.…”

Impact of biofertilisers on iron homeostasis and grain quality in the rice variety Uma under Elevated CO2

The diminishing nutritional quality of rice with increasing concentrations of atmospheric CO2 is currently a major global concern. The present study was designed with the objective of assessing the impact of biofertilisers on grain quality and iron homeostasis in rice under elevated CO2. A completely randomised design with four treatments ([KAU, POP (control), POP+Azolla, POP+PGPR, and POP+AMF]), each replicated three times under ambient and elevated CO2 conditions, was followed. The analysed data revealed that yield, grain quality, and iron uptake and translocation were modified in an unfavourable manner under elevated CO2, which was reflected in the lower quality and iron content of the grains. The response of iron homeostasis in the experimental plants to the application of biofertilisers, especially plant-growth-promoting rhizobacteria (PGPR), under elevated CO2 strongly suggests the possibility of utilising them for designing iron management strategies for achieving higher quality in rice.

“…Rice grains grown at elevated CO 2 have 5.2% lower iron content than those grown at ambient CO 2 (Myers et al, 2014). Under elevated CO 2 , iron content in rice grains was reduced by nine percent in a study by Jena et al (2018). Rice grain Fe concentration was lowered by 10.9 percent during polishing (Ujiie et al, 2019).…”

“…However, there is uncertainty about how plants adapt to eCO 2 . Experiments using free‐air carbon dioxide enrichment (FACE), in which plants are grown at eCO 2 concentrations under field conditions have confirmed that eCO 2 brings about an increase in photosynthetic rates as well as crop yield (Ainsworth & Long, 2005; Jena et al., 2018; Pan et al., 2018). But increased productivity is reported to bring about a reduction in the nutritional quality of food crops (Broberg et al., 2017; Loladze, 2014; Pilbeam, 2015).…”

Atmospheric CO2 levels on Earth have risen steeply over the last 60 years and will continue to do so in future. CO2 traps heat from earth's surface, which causes an increase in temperature and leads to other climatic changes. Crop plants are currently challenged by climate change. In general, elevated CO2 increases photosynthetic rates, plant growth and the ability of plants to counteract stress. However, the effect of eCO2 on respiration is not apparent. Plants growing at eCO2 probably do not have sufficient respiratory ATP to drive cellular processes like nutrient uptake and transport, which impairs their nutritional quality. Here, we review how eCO2 modulates growth and nutritional value of crop plants, emphasizing the contribution of photosynthesis and respiration. We highlight the mechanisms that modulate acclimation and adaptive responses of plants to eCO2 and also discuss the ecological consequences. Finally, we project sorghum as a model for an eCO2 ready crop.

“…K is involved in translocation, stomatal regulation, and carbon fixation (Cakmak et al 1994;Hawkesford et al 2012). An increase in leaf K may indicate an imbalance of these mechanisms in the plants exposed to eCO 2 , since eCO 2 can also promote K uptake, for example, in rice (Jena et al 2018). However, variations in K are not always consistent since they seem to decrease in soybean leaves (Singh et al 2017), and in bamboo plants, it is speciesdependent (Zhuang et al 2018).…”

Aims Elevated atmospheric CO2 (eCO2) and restricted iron (Fe) supply are known to impact plant growth and nutritional quality of food crops. However, studies aimed at understanding how eCO2 will interact with Fe deficiency are scarce. Changes in the nutritional status of the common bean (Phaseolus vulgaris L.) may significantly impact the nutritional status of populations that rely heavily on this crop. Methods To understand the combined effects of eCO2 and Fe deficiency on mechanisms relevant to plant nutrient uptake and accumulation, common bean plants were grown under Fe sufficiency (Fe+, 20 mM Fe-EDDHA) and Fe deficiency (Fe-, 0 mM Fe-EDDHA) combined with eCO2 (800 ppm) or ambient CO2 (aCO2, 400 ppm) in hydroponics until maturity. Results Elevated CO2, besides stimulating photosynthesis and stomatal closure, highly affected plant Fe metabolism: stimulated root ferric chelate reductase (FCR) activity by 6-fold and downregulated the expression of root FRO1 and IRT1 expressions by about 4-fold. In leaves, citrate and oxalate increased, but ferritin expression decreased by 9-fold. Such changes may have determined the differences on mineral accumulation patterns particularly the lower levels of Fe in roots (62%), leaves (38%) and seeds (50%). The combination of Fe deficiency and eCO2 doubled the effect of a single factor on FCR up-regulation, balanced the internal pH of Fe deficient plants, and resulted in the lowest Fe accumulation in all plant parts. Conclusions These results suggest that eCO2 directly affects the Fe uptake mechanism of common bean plants, decreasing plant Fe content.
