Recent advances in understanding thermomorphogenesis signaling

Current Opinion in Plant Biology, Год журнала: 2022, Номер 68, С. 102231 - 102231

Plants show remarkable phenotypic plasticity and are able to adjust their morphology development diverse environmental stimuli. Morphological acclimation responses elevated ambient temperatures collectively termed thermomorphogenesis. In Arabidopsis thaliana, morphological changes coordinated a large extent by the transcription factor PHYTOCHROME-INTERACTING FACTOR 4 (PIF4), which in turn is regulated several thermosensing mechanisms modulators. Here, we review recent advances identification of factors that regulate thermomorphogenesis seedlings affecting PIF4 expression activity. We summarize newly identified highlight work on emerging topic organ- tissue-specificity regulation

Coordinated histone variant H2A.Z eviction and H3.3 deposition control plant thermomorphogenesis

New Phytologist, Год журнала: 2023, Номер 238(2), С. 750 - 764

Опубликована: Янв. 17, 2023

Summary Plants can sense temperature changes and adjust their development morphology accordingly in a process called thermomorphogenesis. This phenotypic plasticity implies complex mechanisms regulating gene expression reprogramming response to environmental alteration. Histone variants often associate with specific chromatin states; yet, how deposition/eviction modulates transcriptional induced by cues remains elusive. In Arabidopsis thaliana , elevation‐induced activation at thermo‐responsive genes entails the eviction of histone variant H2A.Z INO80, which is recruited these loci via interacting key thermomorphogenesis regulator PIF4. Here, we show that both INO80 deposition chaperones another H3.3 ELF7, critical component transcription elongator PAF1 complex. promotes high temperature‐enhanced RNA Pol II PIF4 targets, it broadly required for removal‐induced activation. Reciprocally, ELF7 regulate deposition, are necessary temperature‐induced enrichment targets. Our findings demonstrate close coordination between temperature, pinpoint importance dynamics regulation.

The complex transcriptional regulation of heat stress response in maize

Stress Biology, Год журнала: 2024, Номер 4(1)

Опубликована: Апрель 26, 2024

As one of the most important food and feed crops worldwide, maize suffers much more tremendous damages under heat stress compared to other plants, which seriously inhibits plant growth reduces productivity. To mitigate heat-induced adapt high temperature environment, plants have evolved a series molecular mechanisms sense, respond temperatures stress. In this review, we summarized recent advances in regulations underlying sensing, response memory maize, especially focusing on several pathways signals complex transcriptional regulation ZmHSFs (Heat Shock Factors) response. addition, highlighted interactions between epigenetic factors coordinately regulating memory. Finally, laid out strategies systematically elucidate regulatory network response, discussed approaches for breeding future heat-tolerance maize.

Abstract Heterotrimeric G-proteins, comprising Gα, Gβ, and Gγ subunits, act as crucial molecular switches for signaling transduction in all eukaryotic organisms. Through precise modulation of specific receptors or effectors coupled with heterotrimeric G-proteins cascades, plants have the capability to activate suppress unique pathways necessary plant growth, development, stress responses. This review provides an overview pathway obtained date, highlights novel areas future exploration agricultural application based on emerging significance potential G proteins regulating development responses abiotic stress.

Abstract Heat stress has a deleterious effect on male fertility in rice (Oryza sativa), but mechanisms to protect against heat gametophytes are poorly understood. Here, we have isolated and characterized heat-sensitive male-sterile mutant, shock protein60-3b (oshsp60-3b), that shows normal at optimal temperatures decreasing as increase. High interfered with pollen starch granule formation reactive oxygen species (ROS) scavenging oshsp60-3b anthers, leading cell death abortion. In line the mutant phenotypes, OsHSP60-3B was rapidly upregulated response its protein products were localized plastid. Critically, overexpression of enhanced tolerance transgenic plants. We demonstrated interacted FLOURY ENDOSPERM6(FLO6) plastids, key component involved pollen. Western blot results showed FLO6 level substantially decreased anthers high temperature, indicating is required stabilize when exceed conditions. suggest interacts regulate biogenesis attenuates ROS levels ensure gametophyte development rice.

Transcription factor CaHDZ15 promotes pepper basal thermotolerance by activating HEAT SHOCK FACTORA6a

PLANT PHYSIOLOGY, Год журнала: 2024, Номер 195(1), С. 812 - 831

Опубликована: Янв. 25, 2024

Abstract High temperature stress (HTS) is a serious threat to plant growth and development crop production in the context of global warming, response HTS largely regulated at transcriptional level by actions various transcription factors (TFs). However, whether how homeodomain-leucine zipper (HD-Zip) TFs are involved thermotolerance unclear. Herein, we functionally characterized pepper (Capsicum annuum) HD-Zip I TF CaHDZ15. CaHDZ15 expression was upregulated abscisic acid basal via loss- gain-of-function assays virus-induced gene silencing overexpression Nicotiana benthamiana plants. acted positively directly targeting activating HEAT SHOCK FACTORA6a (HSFA6a), which further activated CaHSFA2. In addition, interacted with PROTEIN 70-2 (CaHsp70-2) glyceraldehyde-3-phosphate dehydrogenase1 (CaGAPC1), both affected thermotolerance. CaHsp70-2 CaGAPC1 promoted binding promoter CaHSFA6a, thus enhancing its transcription. Furthermore, were protected from 26S proteasome-mediated degradation physical interaction. These results collectively indicate that CaHDZ15, modulated interacting partners CaHsp70-2, promotes transcript CaHSFA6a. Thus, molecular linkage established among CaGAPC1, transcriptionally modulate CaHSFA6a
