Plants are constantly exposed to abiotic and biotic stresses that seriously affect crop yield quality. A coordinated regulation of plant responses combined abiotic/biotic requires crosstalk between signaling pathways initiated by each stressor. Interconnected further finetune stress allow the respond such effectively. The nutritional status might influence disease resistance strengthening or weakening immune responses, as well through modulation pathogenicity program in pathogen. Here, we discuss advances our understanding interactions nutrient stress, deficiency excess, context current agricultural practices. introduction chemical fertilizers pesticides was a major component Green Revolution 1960s greatly boosted production. However, massive application agrochemicals also has adverse consequences on environment animal/human health. Therefore, an in-depth connections caused overfertilization (or low bioavailability nutrients) is timely novel field research with important implications for control species. Optimizing management practices tailored specific environmental conditions will be crucial maximizing production using environmentally friendly systems.

Tomato mitogen-activated protein kinase: mechanisms of adaptation in response to biotic and abiotic stresses

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: Feb. 3, 2025

Plants live under various biotic and abiotic stress conditions, to cope with the adversity severity of these they have developed well-established resistance mechanisms. These mechanisms begin perception stimuli, followed by molecular, biochemical, physiological adaptive measures. Tomato ( Solanum lycopersicum ) is a globally significant vegetable crop that experiences several events can adversely impact its quality production. Mitogen-activated protein kinases (MAPKs) in tomato plants crucial functions mediating responses environmental cues, internal signals, defense mechanisms, cellular processes, plant development growth. MAPK cascades respond factors modulating associated gene expression, influencing hormone synthesis, facilitating interactions other stressors. Here, we review evolutionary relationships 16 SlMAPK family members emphasize on recent studies describing regulatory SlMAPKs both conditions. This could enhance our comprehension network conditions provide theoretical support for breeding tomatoes agronomic traits excellent resistance.

An Integrative Computational Approach for Identifying Cotton Host Plant MicroRNAs with Potential to Abate CLCuKoV-Bur Infection

Viruses, Journal Year: 2025, Volume and Issue: 17(3), P. 399 - 399

Published: March 12, 2025

Cotton leaf curl Kokhran virus-Burewala (CLCuKoV-Bur) has a circular single-stranded ssDNA genome of 2759 nucleotides in length and belongs to the genus Begomovirus (family, Geminiviridae). CLCuKoV-Bur causes cotton disease (CLCuD) is transmitted by whitefly Bemisis tabaci cryptic species. Monopartite begomoviruses encode five open reading frames (ORFs). replicates through dsDNA intermediate. Five (ORFs) are organized small circular, (ss)-DNA (2759 bases). RNA interference (RNAi) naturally occurring process that revolutionized targeting gene regulation eukaryotic organisms combat virus infection. The aim this study was elucidate potential binding attractions cotton-genome-encoded microRNAs (Gossypium hirsutum-microRNAs, ghr-miRNAs) on ssDNA-encoded mRNAs using online bioinformatics target prediction tools, RNA22, psRNATarget, RNAhybrid, TAPIR. Using suite robust algorithms, predicted repertoire microRNA-binding landscape determined for consensus sequence. Previously experimentally validated hirsutum L.) miRNAs (n = 80) were selected from public repository miRNA registry miRBase (v22) hybridized silico into (AM421522) coding non-coding sequences. Of 80 ghr-miRNAs interrogated, 18 identified two four algorithms evaluated. Among them, ghr-miR399d (accession no. MIMAT0014350), located at coordinate 1747 genome, or “union” all represents an optimal designing artificial microRNA (amiRNA) silencing construct planta expression. Based predictions, ghr-miRNA-regulatory network developed ORFs Circos software version 0.6. These results represent first predictions with therapeutic developing CLCuD resistance upland plants.
