A relative of cultivated rice (Oryza sativa L.), weedy or red rice (Oryza spp.) is currently recognized as the dominant weed, leading to a drastic loss of yield of cultivated rice due to its highly competitive abilities like producing more tillers, panicles, and biomass with better nutrient uptake. Due to its high nutritional value, antioxidant properties (anthocyanin and proanthocyanin), and nutrient absorption ability, weedy rice is gaining immense research attentions to understand its genetic constitution to augment future breeding strategies and to develop nutrition-rich functional foods. Consequently, this review focuses on the unique gene source of weedy rice to enhance the cultivated rice for its crucial features like water use efficiency, abiotic and biotic stress tolerance, early flowering, and the red pericarp of the seed. It explores the debating issues on the origin and evolution of weedy rice, including its high diversity, signalling aspects, quantitative trait loci (QTL) mapping under stress conditions, the intricacy of the mechanism in the expression of the gene flow, and ecological challenges of nutrient removal by weedy rice. This review may create a foundation for future researchers to understand the gene flow between cultivated crops and weedy traits and support an improved approach for the applicability of several models in predicting multiomics variables. © 2024 John Wiley & Sons Ltd.

Arbuscular mycorrhizal fungi (AMF) are symbiotic organisms that form intimate relationships with host plants by developing intracellular structures called arbuscules within root cortical cells. They are vital to natural ecosystems, offering a range of ecological benefits. They enhance the uptake and transfer of essential nutrients, influence the composition of fungal and bacterial communities in the soil, and improve soil texture and structure. They also strengthen plant resilience by mitigating the effects of salinity, drought, extreme temperatures, pathogens, pests, and weeds. They support plant defense mechanisms through the production of antimicrobial compounds, induction of defense-related biomolecules, and activation of resistance genes. This article provides a thorough review of recent research on the interactions between plant nutrients and AMF. It explores key mechanisms in nutrient uptake, and examines the morphological, biochemical, and molecular changes in plants colonized by AMF. Additionally, the article discusses AMF's crucial role in alleviating biotic stress. By shedding light on these aspects, the review identifies research gaps and suggests future directions. Harnessing AMF's potential can reduce dependence on agrochemicals and promote a more sustainable agricultural system. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.
