Transcriptomic response to three osmotic stresses in gills of hybrid tilapia (Oreochromis mossambicus female × O. urolepis hornorum male)

tailieu.vn

In the present study and 3050 significantly different expression genes were identified in salinity stress, alkalinity stress and saline-alkaline stress, respect- ively. Numer- ous ion transport enzymes and ion transporters associ- ated with osmoregulation were identified in the three osmotic stress groups. Zhu et al found that the NKA α 1 mRNA expression levels in the gills of tilapia reached peak level at 24 h after transfer from freshwater to seawater [45].

Abiotic stress: A constraint in farming

tailieu.vn

Heat stress degrades meiosis, decreased pollen germination and growth of the pollen tube, reduced viability, stigmatic and style anomalies, reduced stigmatic pollen grains, disrupted fertilisation process, endosperm growth barriers and unfertilised embryos.. Osmotic pressure due to salinity increases the osmotic stress in. the plant cells, thereby limiting the plant ability to take water and minerals like K + and Ca 2.

Transcriptome sequencing and whole genome expression profiling of hexaploid sweetpotato under salt stress

tailieu.vn

In the current study, the response of leaf tissues was lower dur- ing the first hours of salt stress and there were only four TFs significantly up-regulated with one fold higher than control.

For example, the activation of the Arabidopsis stress-responsive gene AtDREB2A, whose expression increases plant tolerance to osmotic stress [23, 24], requires repression of at least one GRF. These resources provide the foundation for identifying the suite of GRF genes in Gossypium and their potential roles as salt stress-related genes. Here, we report our genome-wide analysis of the.

Under cold and osmotic stress, the expression of the AT1G21010 gene was significantly upregulated in aerial parts (Figs. The ex- pression of the AT1G29195 gene in aerial tissues was upreg- ulated under salt stress and osmotic stress, while its expression was significantly downregulated under cold stress (Figs. These findings indicate that At5G67620 may participate in the movement of the stomata via interacting with AT3G08530..

Understanding the early cold response mechanism in IR64 indica rice variety through comparative transcriptome analysis

tailieu.vn

The Dehydration Responsive Element (DRE) cis-acting elements are involved in both osmotic and cold stress induced gene expression. While osmotic stress response involves changes in DREB2 regulon gene expression, DREB1 genes are majorly responsible for mounting the cold stress response in plants [76]. In this study, sig- nificant upregulation of the DREB1 gene cassette prompted us to focus on the DREB regulon genes.

The Arabidopsis LOS5/ABA3 locus encodes a molybdenum cofactor sulfurase and modulates cold stress – and osmotic stress – responsive gene expression. Identification and expression analysis of the stress resistance gene JrGSTU23 from Juglans regia

Integrated analysis of co-expression, conserved genes and gene families reveal core regulatory network of heat stress response in Cleistogenes songorica, a xerophyte perennial desert plant

Furthermore, 12 conserved DEGs were involved in ‘heat acclimation’, and another 12 were involved in the ‘response to osmotic stress’ (Fig. for example, 16 and 13 con- served DEGs were enriched in the ‘chloroplast envelope’. The KEGG pathway analysis revealed that some con- served DEGs were involved in the biosynthesis of differ- ent metabolites, including lipids and sugars (Fig.

Coding and long non-coding RNAs provide evidence of distinct transcriptional reprogramming for two ecotypes of the extremophile plant Eutrema salsugineum undergoing water deficit stress

tailieu.vn

Despite this unusually high tolerance to osmotic stress, MacLeod et al. [17] reported that the Yukon and Shandong Eutrema salsugineum accessions respond differently to a drought treatment that includes two periods of water deficit sepa- rated by a brief recovery period. Plants of the Yukon acces- sion accumulate solutes in response to an initial water deficit and during a second drought treatment the plants retain water content longer and maintain leaf expansion..

Multiple Arabidopsis mTERF genes functions have been tested, for instance, Atm- TERF5, 9, 10 and 11 have functions on the resistance to salt and osmotic stress, and AtmTERF5, 9 and 10 also play roles in responding to ABA regulation [40]. Al- though the Arabidopsis mTERF genes can provide pre- dicted characterization for VvmTERF genes, the functional analysis of VvmTERF genes homologs still need more detailed experimental demonstration..

Whole-genome characterization of Rosa chinensis AP2/ERF transcription factors and analysis of negative regulator RcDREB2B in Arabidopsis

tailieu.vn

Analysis of the osmotic stress-responsive genes and ABA-related genes in VC and RcDREB2B transgenic lines was performed using RT-qPCR. Fifteen cis- acting regulatory elements were found in RcAP2/ERF roses, including ABRE, LTR, MYB, MYC, and DRE, and were designated to 1.5 kb upstream of the RcAP2/ERF ini- tiation codon. When the cis-regulatory elements were ex- amined they showed, that the promoter sequences of the RcAP2/ERF genes were not uniformly distributed.
