The present day's ongoing global warming and climate change adversely affect plants through imposing environmental (abiotic) stresses disease pressure. major abiotic factors such as drought, heat, cold, salinity, etc., hamper a plant's innate growth development, resulting in reduced yield quality, with the possibility of undesired traits. In 21st century, advent high-throughput sequencing tools, state-of-the-art biotechnological techniques bioinformatic analyzing pipelines led to easy characterization plant traits for stress response tolerance mechanisms by applying 'omics' toolbox. Panomics pipeline including genomics, transcriptomics, proteomics, metabolomics, epigenomics, proteogenomics, interactomics, ionomics, phenomics, have become very handy nowadays. This is important produce climate-smart future crops proper understanding molecular responses genes, transcripts, proteins, epigenome, cellular metabolic circuits resultant phenotype.

Soil acidification and salinity: the importance of biochar application to agricultural soils

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 14

Published: Sept. 14, 2023

Soil acidity is a serious problem in agricultural lands as it directly affects the soil, crop production, and human health. acidification occurs due to release of protons (H + ) from transforming reactions various carbon, nitrogen, sulfur-containing compounds. The use biochar (BC) has emerged an excellent tool manage soil owing its alkaline nature appreciable ability improve soil’s physical, chemical, biological properties. application BC acidic soils improves pH, organic matter (SOM), cation exchange capacity (CEC), nutrient uptake, microbial activity diversity, enzyme activities which mitigate adverse impacts on plants. Further, also reduce concentration H Al 3+ ions other toxic metals supports plant growth. Similarly, salinity (SS) concern across globe direct impact global production food security. Due liming potential important amendment SS. addition saline homeostasis, SOM, CEC, activity, enzymatic water uptake reduces accumulation sodium (Na chloride (Cl - ). All these BC-mediated changes support growth by improving antioxidant photosynthesis efficiency, stomata working, decrease oxidative damage Thus, present review, we discussed mechanisms through properties counter problems. review will increase existing knowledge about role This provide new suggestions readers how this can be used ameliorate soils.

Time-Course Transcriptomics Analysis Reveals Molecular Mechanisms of Salt-Tolerant and Salt-Sensitive Cotton Cultivars in Response to Salt Stress

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(1), P. 329 - 329

Published: Jan. 2, 2025

Salt stress is an environmental factor that limits plant seed germination, growth, and survival. We performed a comparative RNA sequencing transcriptome analysis during germination of the seeds from two cultivars with contrasting salt tolerance responses. A transcriptomic comparison between salt-tolerant cotton cv Jin-mian 25 salt-sensitive Su-mian 3 revealed both similar differential expression patterns genotypes stress. The genes related to aquaporins, kinases, reactive oxygen species (ROS) scavenging, trehalose biosynthesis, phytohormone biosynthesis signaling include ethylene (ET), gibberellin (GA), abscisic acid (ABA), jasmonic (JA), brassinosteroid (BR) were systematically investigated cultivars. Despite involvement these in cotton’s response positive or negative ways, their levels mostly genotypes. Interestingly, PXC2 gene (Ghir_D08G025150) was identified, which encodes leucine-rich repeat receptor-like protein kinase (LRR-RLK). This showed induced pattern after treatment but not 3. Our multifaceted approach illustrated cotton.
