Heat shock response and transposon control in plant shoot stem cells [RNA-seq]

Project description:Post-embryonic plant development must be coordinated in response to and with environmental feedback. Development of above-ground organs is orchestrated from stem cells in the center of the shoot apical meristem (SAM). Heat can pose significant abiotic stress to plants and induce a rapid heat shock response, developmental alterations, chromatin decondensation, and activation of transposable elements (TEs). However, most plant heat-stress studies are conducted with seedlings, and we know very little about cell-type-specific responses. Here we use fluorescent-activated nuclear sorting to isolate and characterize stem cells of wild type and mutants defective in TE defense and chromatin compaction after heat shock and after a long recovery. Our results indicate that stem cells can suppress heat shock response pathways to maintain developmental programs. Furthermore, mutants defective in DNA methylation fail to recover efficiently from heat stress and persistently activate heat shock factors and heat-inducible TEs. Heat stress also induces DNA methylation epimutations, especially in the CHG context, and we find hundreds of DNA methylation changes three weeks after stress. Our results underline the importance of disentangling cell type-specific environmental responses for understanding plant development.

Immediate transcriptional responses to heat shock of plant leaf

Project description:Ambient temperature is one of the most important environment factors that direct all organisms for morphogenesis, metabolisms and growth. Plants have evolved efficient mechanisms adapting temperature fluctuation such as heat stress response (HSR). Although transcriptional regulatory network of plant HSR has been established, little is known on the genome-wide transcriptional changes within first several minutes upon heat shock (HS). To precisely measure the very first wave of transcriptional response to HS, we investigated the nascent RNA and mature mRNA from plant leaf tissue exposure to 5-min HS treatment using global run-on sequencing (GRO-seq) and RNA sequencing (RNA-seq) methods. We found that only a small group of genes were both up- or down-regulated at nascent RNA and mRNA levels. Primed plants that already exposed to a mild heat stress induced a more drastic transcriptomic alteration than naïve plants which had not experienced a heat stress. Group A1 HEAT SHOCK TRANSCRIPTION FACTORs (HsfA1s) are the major transcription factors in charge of the very early transcriptional HSR. Within 5-minute HS, we also observed that: 1) Engaged RNA polymerase II (Pol II) was accumulated downstream of transcription start sites; 2) 5' pause-release is a rate limiting step for induction of some heat shock protein genes; 3) A good number of genes switched transcription modes; 4) Pervasive read-through was induced at terminators. Plants' HSR is transcriptionally very quick. GRO-seq is sensitive and robust to detect quick response to HS. Heat stress memory takes place at multiple steps of transcription cycles such as Pol II recruitment, 5' pausing, elongation and termination.

Transcriptome analysis revealed that Arabidopsis model plant invokes the activation of heat shock proteins and ER stress response against cesium stress

Project description:We investigated the root growth of several knockout mutants of heat shock protein family genes and found that heat stress response was compromised in these mutants compared to wild type plants. It suggested that heat shock protein genes including heat shock protein genes including HSP17s, HSP23s, HSP101, and HSFA2 proteins are deployed upon exposure to Cs for plant stress tolerance. Our study provided novel insights into the molecular events occurring in Cs-stressed plants.

Differential regulation of HSFA1s and HSFA2 after heat shock in Arabidopsis

Project description:HSFA1s are a gene family of HSFA1 with four members, HSFA1a, HSFA1b, HSFA1d, and HSFA1e. HSFA1s are the master regulators of heat shock response. As a part of the heat shock response, HSFA2 can prolong the heat shock response and amplify the heat shock response in response to repeat heat shock. To identify the heat-shock-responsive genes differentially regulated by HSFA1s and HSFA2, we compared the transcriptomic differences of plants containing only constitutively expressed HSFA1s or HSFA2 after heat stress. hsfa2 (the KO mutant of HSFA2, Col-0 background) and A2QK-10 (CaMV 35S:HSFA2 in QK mutant; QK is HSFA1a/b/d/e quadruple KO mutant) were used to compare the difference of heat shock response when plants lack HSFA1s or HSFA2. The aim is to find the HSFA1s- and HSFA2-preferred regulating genes after heat stress. As the control samples, wild type is the plant with normal heat shock response, and QK (HSFA1s KO mutant, Col-0 and Ws mixed background) is the plant that lost the heat shock response controlled by HSFA1s.
