Signal Transduction in Cereal Plants Struggling with Environmental Stresses: From Perception to Response

Plants, Journal Year: 2022, Volume and Issue: 11(8), P. 1009 - 1009

Published: April 7, 2022

Cereal plants under abiotic or biotic stressors to survive unfavourable conditions and continue growth development, rapidly precisely identify external stimuli activate complex molecular, biochemical, physiological responses. To elicit a response the stress factors, interactions between reactive oxygen nitrogen species, calcium ions, mitogen-activated protein kinases, calcium-dependent calcineurin B-like interacting kinase, phytohormones transcription factors occur. The integration of all these elements enables change gene expression, release antioxidant defence repair systems. There are still numerous gaps in knowledge on subjects literature caused by multitude signalling cascade components, simultaneous activation multiple pathways intersection their individual both single stresses. Here, signal transduction cereal drought, salinity, heavy metal stress, pathogen, pest attack, as well crosstalk reactions during double responses discussed. This article is summary latest discoveries it integrates available information better outline whole research problem for future challenges creative breeding stress-tolerant cultivars cereals.

Hormonal and epigenetic regulation of root responses to salinity stress

The Crop Journal, Journal Year: 2024, Volume and Issue: 12(5), P. 1309 - 1320

Published: March 13, 2024

Salinity stress is a major environmental affecting crop productivity, and its negative impact on global food security only going to increase, due current climate trends. tolerance was present in wild relatives but significantly weakened during domestication. Regaining it back requires good understanding of molecular mechanisms traits involved control plant ionic ROS homeostasis. This review summarizes our knowledge the role hormones (auxin, cytokinins, abscisic acid, salicylic jasmonate) plants adaptation soil salinity. We firstly discuss controlling root tropisms, growth architecture (primary elongation, meristematic activity, lateral development, hairs formation). Hormone-mediated uptake sequestration key inorganic ions (sodium, potassium, calcium) then discussed followed by regulation cell redox balance signaling salt-stressed roots. Finally, epigenetic alterations such as DNA methylation histone modifications ion homeostasis discussed. data may help develop novel strategies for breeding cultivating salt-tolerant crops improving agricultural productivity saline regions.

Sweet sorghum is a C4 crop that can be grown for silage forage, fiber, syrup and fuel production. It generally considered salt-tolerant plant. However, the salt tolerance ability varies among genotypes, mechanism not well known. To further uncover mechanism, we performed comparative transcriptome analysis with RNA samples in two sweet genotypes showing different abilities (salt-tolerant line RIO salt-sensitive SN005) upon treatment. These response processes mainly focused on secondary metabolism, hormone signaling stress response. The expression pattern cluster showed RIO-specific genes were significantly enriched categories related to metabolic pathways. GO enrichment indicated responded earlier than SN005 2 h after In addition, identified more transcription factors (TFs) specifically expressed differently first of treatment, TF change was obviously different. results indicate an early metabolism might essential sorghum. conclusion, found response, especially signaling,
