“…It plays a significant role in global food consumption by people around the world ( Xu et al, 2021 ). Due to changes in climatic conditions and geographical location, the crop is challenged by various biotic and abiotic stresses ( Vaishnav et al, 2014 ; Hussain and Mahmood, 2020 ). Among which, one of the main concern is the rice false smut disease caused by U. virens, posing a major threat to rice production.…”

Rice false smut, which is caused by the soil-borne fungal pathogen Ustilaginoidea virens (U. virens), is one of the most threatening diseases in most of the rice-growing countries including India that causes 0.5–75% yield loss, low seed germination, and a reduction in seed quality. The assessment of yield loss helps to understand the relevance of disease severity and facilitates the implementation of appropriate management strategies. This study aimed to mitigate biotic stress in rice by employing a rhizobacterial-based bioformulation, which possesses diverse capabilities as both a plant growth promoter and a biocontrol agent against U. virens. Rhizobacteria were isolated from the soil of the rice rhizospheres from the healthy plant of the false smut affected zone. Furthermore, they were identified as Bacillus strains: B. subtilis (BR_4), B. licheniformis (BU_7), B. licheniformis (BU_8), and B. vallismortis (KU_7) via sequencing. Isolates were screened for their biocontrol potential against U. virens under in vitro conditions. The antagonistic study revealed that B. vallismortis (KU_7) inhibited U. virens the most (44.6%), followed by B. subtilis BR_4 (41.4%), B. licheniformis BU_7 (39.8%), and B. licheniformis BU_8 (43.5%). Various biochemical and plant growth promoting attributes, such as phosphate and Zn solubilization, IAA, ammonium, siderophore, and chitinase production, were also investigated for all the selected isolates. Furthermore, the potential of the isolates was tested in both in vitro and field conditions by employing talc-based bioformulation through bio-priming and root treatment. The application of bioformulation revealed a 20% decrease in disease incidence in plants treated with B. vallismortis (KU_7), a 60.5% increase in the biological yield, and a 45% increase in the grain yield. This eco-friendly approach not only controlled the disease but also improved the grain quality and reduced the chaffiness.

“…According to molecular research, allopolyploid Gossypium originated about 1.5 million years ago, during the mid Pleis tocene [2,[11][12][13]. Allopolyploid cotton is believed to have originated via the transoceanic dispersion of Agenome species to the New World by hybridization with indigenous diploid D genome species.…”

Over the past two decades, biotechnology has yielded Bt cotton, a huge success in the field of agriculture. In a number of countries, commercial Bt crop production has proven successful. The global food scarcity crisis has been alleviated by transgenic Bt crops, which have improved agricultural productivity. The Bt cotton crop displays variable levels of insect resistance to several environmental abiotic circumstances, including high temperatures, salt in the soil, water logging and scarcity, inadequate nitrogen supply, and humidity. It has been demonstrated that these components lessen the transgenic crop's endotoxin protein level, which in turn reduces the insecticidal efficacy of the crop. In unfavourable climatic conditions, plants have altered nitrogen metabolism and pain in their physiological systems. This article has discussed some of the primary stresses that Bt cotton encounters as well as the underlying mechanisms that explain its variable insecticidal efficacy under both single and combination pressures. While several important elements are covered in this study, such as gene silencing, post transcriptional changes, and protein breakdown, the most important aspect of this field that still need investigation is nitrogen metabolism. A thorough meta-analysis table provides an overview of the several significant research that have been carried out to examine the impacts of stress. A comprehensive study technique is needed to clarify the metabolic and physiological changes that transpire in transgenic cotton crops under high stress. In order to increase the production and performance of the cotton crop worldwide, more research is needed to address the unpredictable insect resistance of Bt crops.

“…It is important that herbicides just kill the weeds and not the crop plants. Traditionally, DNA recombinant technology or a transgenic approach has been utilized extensively to improve herbicide resistance in corn, cotton, and soybean [69,70]. Due to rigorous biosafety checks for genetically modified organisms (GMO) or transgenic plants, CRISPR/Cas9-mediated herbicide resistance has become more popular in recent years [18,48,71,72].…”

Food crop production and quality are two major attributes that ensure food security. Rice is one of the major sources of food that feeds half of the world’s population. Therefore, to feed about 10 billion people by 2050, there is a need to develop high-yielding grain quality of rice varieties, with greater pace. Although conventional and mutation breeding techniques have played a significant role in the development of desired varieties in the past, due to certain limitations, these techniques cannot fulfill the high demands for food in the present era. However, rice production and grain quality can be improved by employing new breeding techniques, such as genome editing tools (GETs), with high efficiency. These tools, including clustered, regularly interspaced short palindromic repeats (CRISPR) systems, have revolutionized rice breeding. The protocol of CRISPR/Cas9 systems technology, and its variants, are the most reliable and efficient, and have been established in rice crops. New GETs, such as CRISPR/Cas12, and base editors, have also been applied to rice to improve it. Recombinases and prime editing tools have the potential to make edits more precisely and efficiently. Briefly, in this review, we discuss advancements made in CRISPR systems, base and prime editors, and their applications, to improve rice grain yield, abiotic stress tolerance, grain quality, disease and herbicide resistance, in addition to the regulatory aspects and risks associated with genetically modified rice plants. We also focus on the limitations and future prospects of GETs to improve rice grain quality.
