“…Selecting suitable quantitative trait loci (QTLs) linked with higher Zn uptake can also be an essential approach for producing genetically modified crops with higher Zn contents (Dong et al, 2006). The combination of QTL analysis and molecular genetics can help breed improved crop varieties with better efficiency in nutrient use (Verma et al, 2021). Recently, a genome-wide association study (GWAS) has emerged as an essential tool involved in sequencing methods.…”

“…Bioinformatic tools identify the QTLs and natural variations to characterize the genetic loci controlling the diverse agronomic traits (Huang et al, 2010). Likewise, GWAS is also an effective strategy for identifying QTLs that possess the Zn nutrition trait and is also an efficient way to improve Zn uptake and Zn efficiency in crops (Verma et al, 2021). The transgenic approaches also identified many Zn transporters linked with cations, such as ZRT-IRT-like proteins (ZIP) and cation diffusion facilitator (CDF) families.…”

“…The transgenic approaches also identified many Zn transporters linked with cations, such as ZRT-IRT-like proteins (ZIP) and cation diffusion facilitator (CDF) families. These play an essential role in the uptake and translocation of Zn in plants (Verma et al, 2021). For example, over-expression of AtZIP1 and HvZIP7 in barley plants has increased the grain Zn contents (Tiong et al, 2014).…”

Heavy metal (HM) contamination is a serious concern across the globe, and in recent times, HMs’ intensity has significantly increased, posing a serious threat to crop growth and productivity. Heavy metals pose serious health issues in humans by entering the human food chains. Therefore, it is direly needed to reduce the effects of HMs on plants and humans by adapting appropriate practices. In this context, application of micronutrients can be an essential practice to mitigate the toxic effects of HMs. Zinc (Zn) is a crucial nutrient needed for plant growth, and Zn application reduced the HM-induced toxicity in plants. This review highlights Zn’s role in mitigating the HMs toxicity in plants. We have systematically described the potential mechanisms mediated by Zn to mitigate HMs in plants. Zinc application reduced the HMs uptake and translocation plants, which is considered an essential mechanism of HM stress tolerance. Zn application also improves membrane stability, plant water relationship, nutrient uptake, photosynthetic performance, osmolytes accumulation, anti-oxidant activities, and gene expression. In addition to this, the Zn application substantially improves photosynthesis by enhancing the synthesis of photosynthetic pigments, photosystem activities, enzymatic activities, and maintaining photosynthetic apparatus structure, ensuring better growth under HM stress. Therefore, Zn nutrition could improve the plant performance under HM stress by modulating the plant’s physiological and biochemical functioning, anti-oxidant activities, osmolytes accumulation, and gene expression.

“…Global annual increases in rice production are decreasing at a time of an increasing global population dependent on this crop as a staple food (Bin Rahman and Zhang 2022 ). This has led to an array of efforts to increase rice yield, both by breeding and implementing new agronomic approaches (Saito et al 2021 ; Verma et al 2021 ). Increased yields must be achieved in an environmentally and economically sustainable fashion—inputs to the agronomic system must be maintained at as low a level as feasible, and there must be economic incentives for rice farmers.…”

Tillering and yield are linked in rice, with significant efforts being invested to understand the genetic basis of this phenomenon. However, in addition to genetic factors, tillering is also influenced by the environment. Exploiting experiments in which seedlings were first grown in elevated CO2 (eCO2) before transfer and further growth under ambient CO2 (aCO2) levels, we found that even moderate exposure times to eCO2 were sufficient to induce tillering in seedlings, which was maintained in plants grown to maturity plants in controlled environment chambers. We then explored whether brief exposure to eCO2 (eCO2 priming) could be implemented to regulate tiller number and yield in the field. We designed a cost-effective growth system, using yeast to increase the CO2 level for the first 24 days of growth, and grew these seedlings to maturity in semi-field conditions in Malaysia. The increased growth caused by eCO2 priming translated into larger mature plants with increased tillering, panicle number, and improved grain filling and 1000 grain weight. In order to make the process more appealing to conventional rice farmers, we then developed a system in which fungal mycelium was used to generate the eCO2 via respiration of sugars derived by growing the fungus on lignocellulosic waste. Not only does this provide a sustainable source of CO2, it also has the added financial benefit to farmers of generating economically valuable oyster mushrooms as an end-product of mycelium growth. Our experiments show that the system is capable of generating sufficient CO2 to induce increased tillering in rice seedlings, leading eventually to 18% more tillers and panicles in mature paddy-grown crop. We discuss the potential of eCO2 priming as a rapidly implementable, broadly applicable and sustainable system to increase tillering, and thus yield potential in rice.
