By 2050, the world population will increase to 10 billion which urged global demand for food production double. Plant disease and land drought make situation more dire, safer environment-friendly materials are thus considered as a new countermeasure. The rice blast fungus, Magnaporthe oryzae, causes one of most destructive diseases cultivated worldwide that seriously threatens production. Unfortunately, traditional breeding nor chemical approaches along control it well. Nowadays, nanotechnology stands weapon against these mounting challenges silica nanoparticles (SiO2 NPs) have been potential agrochemicals recently but systematically studies remain limited, especially in rice.Salicylic acid (SA) is key plant hormone essential establishing resistance several pathogens its further affected special form induced resistance, systemic acquired (SAR), an important aspect innate immunity from locally whole plant. Here we showed SiO2 NPs could stimulate protect M. oryzae through foliar treatment significantly decreased severity by nearly 70% within appropriate concentration range. Excessive led disordered intake abnormal SA responsive genes expressions weaken even aggravated disease. Importantly, this SA-dependent fungal achieve better results with root SAR manner no phytotoxicity since orderly moderate absorption. What's more, also promote development was deal drought.Taken together, our findings not only revealed effective safe strategy biotic abiotic stresses, identify application method seems causing negative effects promotion on development.

Rice sheath blight (ShB) disease poses a major threat to rice yield throughout the world. However, defense mechanisms against ShB in remain largely unknown. resistance is typical quantitative trait controlled by multiple genes. With rapid development of molecular methods, many loci (QTLs) related agronomic traits, biotic and abiotic stresses, have been identified genome-wide association studies. The interactions between plants pathogens are various plant hormone signaling pathways, pathways synergistically or antagonistically interact with each other, regulating growth as well response. This review summarizes regulatory effects hormones including auxin, ethylene, salicylic acid, jasmonic brassinosteroids, gibberellin, abscisic strigolactone, cytokinin on crosstalk hormones. Furthermore, sugar nitrogen resistance, information genes their also discussed. In summary, this comprehensive description QTLs, hormones, nutrition, other defense-related rice. prospects targeting mechanism strategy for controlling

Lentil, an important cool season food legume, is a rich source of easily digestible protein, folic acid, bio-available iron, and zinc nutrients. Lentil grows mainly as sole crop in the winter after harvesting rice South Asia. However, annual productivity low due to its slow growth during early phase, competitive weed infestation, disease outbreaks period. Disease resistance breeding has been practiced for long time enhance various diseases. Often sources are available wild relatives. Thus, wide hybridization ovule rescue technique have helped introgress trait into cultivated lentils. Besides hybridization, induced mutagenesis contributed immensely creating variability tolerance, several disease-resistant mutant lines developed. overcome limitations traditional approaches, advancement molecular marker technologies, genomics develop climate-resilient lentil varieties with more precision efficiency.

Mycotoxin contamination in organic and conventional cereal grain and products: A systematic literature review and meta‐analysis

Comprehensive Reviews in Food Science and Food Safety, Journal Year: 2024, Volume and Issue: 23(3)

Published: May 1, 2024

Abstract There is still considerable controversy about the relative risk of mycotoxin exposure associated with consumption organic and conventional cereals. Using validated protocols, we carried out a systematic literature review meta‐analyses data on incidence concentrations mycotoxins produced by Fusarium, Claviceps, Penicillium , Aspergillus species in cereal grains/products. The standard weighted meta‐analysis concentration detected significant effect production system (organic vs. conventional) only for Fusarium deoxynivalenol, ∼50% higher than grains/products ( p < 0.0001). Weighted unweighted also small, but effects and/or T‐2/HT‐2 toxins, zearalenone, enniatin, beauvericin, ochratoxin A (OTA), aflatoxins. Multilevel identified climatic conditions, species, study type, analytical methods used as important confounding factors system. Overall, results from this suggest that (i) contamination decreased between 1990s 2020, (ii) levels are similar cereals human consumption, (iii) maintaining OTA below maximum (3.0 μg/kg) set EU remains major challenge.
