Abstract Background Alternative splicing (AS) is a widespread regulatory mechanism in multicellular organisms. Numerous transcriptomic and single-gene studies plants have investigated AS response to specific conditions, especially environmental stress, unveiling substantial amounts of intron retention that modulate gene expression. However, comprehensive study contrasting stress-response tissue-specific patterns directly comparing them with those animal models still missing. Results We generate massive resource for Arabidopsis thaliana , PastDB comprising expression quantifications across tissues, development including abiotic biotic stresses. Harmonized analysis these datasets reveals A. shows high levels AS, similar fruitflies, that, compared animals, disproportionately uses stress responses. identify core sets genes regulated specifically by either or transcription upon stresses among specialization tightly mirrored the genomic features genes. Unexpectedly, non-intron events, exon skipping, are overrepresented being also largely involved modulating through NMD uORF inclusion. Conclusions Non-intron events likely been functionally underrated plants. constitutes distinct layer controlling internal external stimuli whose target master regulators hardwired at level undergo post-transcriptional regulation. Given higher relevance different when this molecular hardwiring required proper .

Abstract Extreme weather conditions associated with climate change affect many aspects of plant and animal life, including the response to infectious diseases. Production salicylic acid (SA), a central defence hormone 1–3 , is particularly vulnerable suppression by short periods hot above normal growth temperature range via an unknown mechanism 4–7 . Here we show that SA production in Arabidopsis thaliana at 28 °C independent PHYTOCHROME B 8,9 (phyB) EARLY FLOWERING 3 10 (ELF3), which regulate thermo-responsive development.

Plant pathogens are one of the main factors hindering breeding cash crops. Pathogens, including oomycetes, fungus, and bacteria, secrete effectors as invasion weapons to successfully invade propagate in host plants. Here, we review recent advances made field plant-pathogen interaction models action mechanisms phytopathogenic effectors. The illustrates how from different species use similar distinct strategies infect We classify interactions according infestation process: targeting physical barriers for disruption, creating conditions conducive infestation, protecting or masking themselves, interfering with cell physiological activity, manipulating plant downstream immune responses. investigation functioning pathogen contributes improved understanding molecular interactions. This has important theoretical value is practical significance pathology disease resistance genetics breeding.

Understanding the plant-microbe interactions in environments exposed to abiotic stresses: An overview

Microbiological Research, Год журнала: 2023, Номер 271, С. 127368 - 127368

Опубликована: Март 22, 2023

Abiotic stress poses a severe danger to agriculture since it negatively impacts cellular homeostasis and eventually stunts plant growth development. stressors like drought excessive heat are expected occur more frequently in the future due climate change, which would reduce yields of important crops maize, wheat, rice may jeopardize food security human populations. The microbiomes varied taxonomically organized microbial community that is connected plants. By supplying nutrients water plants, regulating their physiology metabolism, microbiota helps plants develop tolerate abiotic stresses, can boost crop yield under stresses. In this present study, with emphasis on temperature, salt, stress, we describe current findings how stresses impact microbiomes, microbe-microbe interactions, plant-microbe interactions as way microorganisms affect metabolism plant. We also explore crucial measures must be taken applying practices faced

Understanding AP2/ERF Transcription Factor Responses and Tolerance to Various Abiotic Stresses in Plants: A Comprehensive Review

International Journal of Molecular Sciences, Год журнала: 2024, Номер 25(2), С. 893 - 893

Опубликована: Янв. 11, 2024

Abiotic stress is an adverse environmental factor that severely affects plant growth and development, plants have developed complex regulatory mechanisms to adapt these unfavourable conditions through long-term evolution. In recent years, many transcription families of genes been identified regulate the ability respond abiotic stresses. Among them, AP2/ERF (APETALA2/ethylene responsive factor) family a large class plant-specific proteins response stresses can also play role in regulating development. This paper reviews structural features classification factors are involved transcriptional regulation, reciprocal proteins, downstream genes, hormone-dependent signalling hormone-independent pathways stress.

The complexity of environmental conditions encountered by plants in the field, or nature, is gradually increasing due to anthropogenic activities that promote global warming, climate change, and increased levels pollutants. While past it seemed sufficient study how acclimate one even two different stresses affecting them simultaneously, complex developing on our planet necessitate a new approach studying stress plants: Acclimation multiple occurring concurrently consecutively (termed, multifactorial combination [MFSC]). In an initial plant response MFSC, conducted with Arabidopsis thaliana seedlings subjected MFSC six abiotic stresses, was found increase number simultaneously impacting plant, growth survival declined, if effects each involved such minimal insignificant. three recent studies, crop plants, have similar commercial rice cultivar, maize hybrid, tomato, soybean, causing significant reductions growth, biomass, physiological parameters, and/or yield traits. As are worsening, as well becoming more complex, addressing its agriculture ecosystems worldwide becomes high priority. this review, we address crops, agriculture, worldwide, highlight potential avenues enhance resilience crops MFSC.
