Water-limiting conditions can severely affect rice yield. Therefore, increasing plant tolerance to water stress is a priority for many breeding programs. However, improving this abiotic comes with several complications related the seeding practices, adopted management system and growth stage where occurs. For reason, it challenging outline single ideotypes showing traits suitable overcoming drought at different times during life cycle of in diverse cropping ecosystems. The current knowledge genomics biochemicals contribute drawing flexible towards availability conditions. Traits identified accessions wild ancestor cultivated rice, as well other species, Oryza glaberrima weedy were demonstrated confer enhanced stress, while screenings germplasms genes/loci resistance. New frontiers are represented by dissection epigenetic control implementation contribution favorable microbiota. Innovative technologies, whose feasibility advancements genomic analyses, contributing enhancing knowledge-based development stress-tolerant varieties.

Dynamics of Humic Acid, Silicon, and Biochar under Heavy Metal, Drought, and Salinity with Special Reference to Phytohormones, Antioxidants, and Melatonin Synthesis in Rice

International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(24), С. 17369 - 17369

This study aimed to develop a biostimulant formulation using humic acid (HA), silicon, and biochar alone or in combination alleviate the lethality induced by combined heavy metals (HM-C; As, Cd, Pb), drought stress (DS; 30-40% soil moisture), salt (SS; 150 mM NaCl) rice. The results showed that HA, Si, application improved plant growth under normal, DS, SS conditions significantly. However, HA increased of rice increasing Pb uptake significantly, thereby elevating lipid peroxidation. Co-application reduced abscisic acid, elevated salicylic optimized Ca2+ Si uptake. subsequently K+/Na+ influx efflux regulating metal ion regulators (Si: Lsi1 Lsi2; K+/Na+: OsNHX1) expressions stress-response genes OsMTP1 OsNramp shoots. Melatonin synthesis was significantly HM-C (130%), which 50% with + treatment. SS- DS-induced crops, melatonin content only minor differences. These findings suggest could be used mitigate precautions should taken when for detoxification.

Abstract Rice output has grown globally, yet abiotic factors are still a key cause for worry. Salinity stress seems to have the more impact on crop production out of all stresses. Currently one most significant challenges in paddy breeding salinity tolerance with help QTLs, is determine QTLs having best chance improving least amount background noise from tolerant parent. Minimizing size QTL confidence interval (CI) essential order primarily include genes responsible tolerance. By considering that, genome-wide meta-QTL analysis 768 35 rice populations published 2001 2022 was conducted identify consensus regions and candidate underlying those tolerance, as it reduces many folds initial studies. In present investigation, total 65 MQTLs were extracted an average CI reduced 17.35 1.66 cM including smallest 0.01 cM. Identification individual traits then classifying target into correlated morphological, physiological biochemical aspects, resulted efficient interpretation identifying understand mechanism whole. The results this study huge potential improve genotypes MAS MABC.

Rice–wheat comparative genomics: Gains and gaps

The Crop Journal, Год журнала: 2023, Номер 12(3), С. 656 - 669

Опубликована: Ноя. 11, 2023

Rice and wheat provide nearly 40% of human calorie protein requirements. They share a common ancestor belong to the Poaceae (grass) family. Characterizing their genetic homology is crucial for developing new cultivars with enhanced traits. Several genes gene families have been characterized based on rice orthologs. Rice–wheat orthology can identify regions that regulate similar traits in both crops. comparative genomics candidate genomic region identified by association or QTL mapping, deduce putative functions biochemical pathways, develop molecular markers marker-assisted breeding. A knowledge facilitates transfer between crops associated desirable engineering, editing, wide crossing.

Raising crops for dry and saline lands: Challenges and the way forward

Plants are continuously exposed to various environmental stresses. Of these, soil salinity and drought considered be the most important stresses globally because they have a negative impact on plant growth crop productivity. Drought thus threaten global food nutritional security. The estimated annual loss in production due saline soils irrigated areas is approximately US$27.3 billion (Qadir et al., 2014). caused direct losses developing world's agriculture order of US$ 29 between 2005 2015 (FAO, 2018). Conversely, there an increasing pressure enhance agricultural by 70% feed predicted increase world population 9.7 2050. Hence, systems must become extremely productive less wasteful throughout world. Achieving this goal will challenging under prevailing conditions coupled with reductions arable land freshwater availability, together climate change-induced uncertainties. Over past six decades, classical breeding technologies played major role performance However, consensus scientific opinion that crops reached their maximum yield potential. challenge for science develop improved varieties can achieve sustainable higher yields limited water availability soils. Recent developments gene editing innovative crucial nature-based roadmap intensification resilience. Salinity disturb ionic osmotic homeostasis cells. plants possess network molecular physiological mechanisms cope these (Karan 2009). Ionic stress triggers burst Ca2+ ions cytoplasm root cells, which activates Salt Overly Sensitive (SOS) signaling pathway comprised three proteins: SOS1, SOS2, SOS3.
