Abiotic Stress in Crop Production

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(7), P. 6603 - 6603

Published: April 1, 2023

The vast majority of agricultural land undergoes abiotic stress that can significantly reduce yields. Understanding the mechanisms plant defenses against stresses and putting this knowledge into practice is, therefore, an integral part sustainable agriculture. In review, we focus on current findings in resistance to four cardinal stressors-drought, heat, salinity, low temperatures. Apart from description newly discovered signaling stress, review also focuses importance primary secondary metabolites, including carbohydrates, amino acids, phenolics, phytohormones. A meta-analysis transcriptomic studies concerning model Arabidopsis demonstrates long-observed phenomenon stressors induce different signals effects at level gene expression, but genes whose regulation is similar under most still be traced. analysis further reveals transcriptional modulation Golgi-targeted proteins response heat stress. Our highlights several are similarly regulated all conditions. These support central role phytohormones response, some these has not yet been studied. Finally, provides information about major European crop plants-wheat, sugar beet, maize, potatoes, barley, sunflowers, grapes, rapeseed, tomatoes, apples.

Crop root system plasticity for improved yields in saline soils

Crop yields must increase to meet the demands of a growing world population. Soil salinization is increasing due impacts climate change, reducing area arable land for crop production. Plant root systems are plastic, and their architecture can be modulated (1) acquire nutrients water growth, (2) respond hostile soil environments. Saline soils inhibit primary growth alter system (RSA) plants. In this review, we explore how adapt salinity, focusing predominately on staple cereal crops wheat, maize, rice, barley, that all play major role in global food security. Cereal classified as glycophytes (salt-sensitive) however salt-tolerance differ both between species within species. past, inherent difficulties associated with visualising measuring traits, breeding strategies have tended focus optimising shoot traits. High-resolution phenotyping techniques now make it possible visualise measure traits systems. A steep, deep cheap ideotype has been proposed nitrogen capture. Changes RSA an adaptive strategy avoid saline whilst nutrient acquisition. review propose new model designing salt-tolerant ideotype.

Abstract Cicer arietinum , Cajanus cajan Vigna radiata and Phaseolus vulgaris are economically important legume crops with high nutritional value. They negatively impacted globally by different biotic abiotic stresses. Hyperosmolality-gated calcium-permeable channels (OSCA) have been characterized as osmosensors in Arabidopsis thaliana but not previously reported legumes. This study provides a genome-wide identification, characterization, comparative analysis of OSCA genes Our identified 13 C. V. P. vulgaris, 12 classified into four distinct clades. We found evidence to suggest that the OSCAs might be involved interaction between hormone signalling pathways stress pathways. Furthermore, they play major role plant growth development.

Due to their immobility and possession of underground parts, plants have evolved various mechanisms endure adapt abiotic stresses such as extreme temperatures, drought, salinity. However, the contribution long noncoding RNAs (lncRNAs) different distinct rice seedling parts remains largely uncharacterized beyond protein-coding gene (PCG) layer.

Alfalfa is an excellent leguminous forage crop that widely cultivated worldwide, but its yield and quality are often affected by drought soil salinization. Hyperosmolality-gated calcium-permeable channel (OSCA) proteins hyperosmotic calcium ion (Ca2+) receptors play essential role in regulating plant growth, development, abiotic stress responses. However, no systematic analysis of the OSCA gene family has been conducted alfalfa. In this study, a total 14 genes were identified from alfalfa genome classified into three groups based on their sequence composition phylogenetic relationships. Gene structure, conserved motifs functional domain prediction showed all MsOSCA had same DUF221. Cis-acting element many cis-regulatory elements response to or biotic stresses hormones. Tissue expression pattern demonstrated tissue-specific expression; for example, MsOSCA12 was only expressed roots leaves not stem petiole tissues. Furthermore, RT-qPCR results indicated induced (drought salt) hormones (JA, SA, ABA). particular, levels MsOSCA3, MsOSCA5, MsOSCA13 significantly increased under salt stress, MsOSCA7, MsOSCA10, exhibited significant upregulation hormone treatments, indicating these positive drought, Subcellular localization MsOSCA3 protein localized plasma membrane.
