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.
Occurrence, Distribution, Damage Potential, and Farmers’ Perception on Fall Armyworm, Spodoptera frugiperda (J.E. Smith): Evidence from the Eastern Himalayan Region

The fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), is a polyphagous non-native pest identified as a serious threat to crop production and food security globally, including in India. Its unintentional introduction and quick coverage in large areas is a serious concern to millions of farmers in the eastern Himalayan region. However, detailed understanding of farmers’ perceptions and the biological attributes associated with the meteorological factors for FAW is limited. The present investigation, which aimed to create baseline data on this pest, concurs with the idea that the FAW is widely dispersed throughout the maize ecosystems of Tripura, with an average infestation rate of 21.33 percent. The severity ranged from 0 to 1.40, with an average leaf damage score of 1 on a 0–4 categorical scale. The findings indicate that pheromone trap catch was significantly correlated with the evaporation rate as other meteorological factors influenced variably. The biological attributes imply that the life cycle was completed in 32.82 ± 0.08 days, with a high fecundity potential (1068.57 ± 4.35 numbers) in controlled conditions (25 ± 1 °C, 70 ± 5% RH). Indigenous natural enemies, such as entomopathogens, spiders, and wasps, were found to be the first defence against this invasive pest. A minority of the population (17.51%) was aware of the incidence of FAW. Furthermore, respondents’ socio-demographic variables were associated significantly with FAW status. This is the first scientific report from the eastern Himalayan region about farmers’ knowledge and awareness of the invasiveness of FAW. This finding enumerates a detailed understanding of FAW from diverse perspectives. Further, the concerted data provide an important baseline that could help the development of holistic management strategies for FAW. © 2023 by the authors.

Silicon (Si), an essential nutrient in the plant health system, are gaining momentum in facilitating defense mechanisms against biotic and abiotic stresses. Recently, Si has received increased attention for its role in alleviating arthropod pests. Albeit many studies focused on direct mechanisms such as physical /mechanical barrier and the biochemical and molecular mode in reinforcing defense activity, the deep insight into the tri-trophic level is obscured. Our study emphasizes the key role of Si in tri-trophic interaction (plant-herbivore-natural enemies), its accumulation in plant tissue, and its consequences on beneficial arthropods. Evidently, the accumulation of Si is greater in monocot tissues than in dicots. We summarize how soil and climatic factors influence Si upregulation in plants. Ironically, the herbivore-induced plant volatiles play a crucial role in defense action, resulting in cascading effects on the attraction of natural enemies, facilitating locating the prey, subsequently strengthening the natural biocontrol. This review explores the abundance of Si in up-regulating the defense activity in the plant by favouring natural enemies and suppressing harmful arthropods, subsequently supporting a green environment and sustainable production system. Further, the present study elucidates variable functions of stress signal hormones like jasmonic acid, salicylic acid, and ethylene in both monocots and dicots. The study also highlights the availability and mode of Si application in response to plant health and emphasizes the future research needs on the role of Si in safeguarding plant health against arthropod pests. © 2022, The Author(s), under exclusive licence to Springer Nature B.V.
Unlocking the Potential of Arbuscular Mycorrhizal Fungi: Exploring Role in Plant Growth Promotion, Nutrient Uptake Mechanisms, Biotic Stress Alleviation, and Sustaining Agricultural Production Systems

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.
