Cabernet Sauvignon grapevines were exposed to sudden chilling (5 degrees C), water deficit (PEG), and an iso-osmotic salinity (120 mM NaCl and 12 mM CaCl(2)) for 1, 4, 8, and 24 h. Stomatal conductance and stem water potentials were significantly reduced after stress application. Microarray analysis of transcript abundance in shoot tips detected no significant differences in transcript abundance between salinity and PEG before 24 h. Chilling stress relates to changes in membrane structure, and t ...[more]

Transcript profiling in Paoenia ostii during chilling induced endo-dormancy release

Project description:To better understanding the genetic and physiological changes behind the dormancy process in tree peony, we performed customized cDNA microarray to investigate gene expression profiling in tree peony ‘Feng Dan Bai’ buds during chilling induced dormancy release. Endo-dormant tree peony plants were exposed to 0-4°C from 5 November to 30 December 2009 in Qingdao, Shandong, China. Buds were collected after 0 d, 6 d, 12 d, 15 d, 18 d and 24 d chilling endured. DNA microarrays were customized using Agilent eArray 5.0 program, containing spots with 14,957 gene-specific 60-mer oligonucleotides representing 14,957 non abundant ESTs obtained from 454 sequencing normalized cDNA of tree peony buds during chilling duration (TSA, 65,217). Total 3,174 significantly differentially-expressed genes (P<0.05) were observed through endo-dormancy release, and the number of up-regulated (1,611) and that of down-regulated (1,563) was almost same. Expression of differentially-expressed genes associated with GA biosynthesis and signaling, cell growth and development was confirmed by quantitative RT-PCR, which displayed similar trends pattern in expression.

Tissue-level transcriptome response to local and distal chilling reveals potential chilling survival mechanisms in maize

Project description:Chilling is a major stress to plants of subtropical and tropical origins including maize. To reveal molecular mechanisms underlying chilling tolerance and chilling survival, we investigated maize transcriptome responses to chilling stress in differentiated leaves and roots as well as in crowns with meristem activity for survival. Chilling stress on maize shoots and roots is found to each contribute to seedling lethality in maize. Comparison of maize lines with different chilling tolerance capacity reveals that chilling survival in maize is highly associated with upregulation in leaves and crowns of abscisic acid response pathway, transcriptional regulators and cold response as well as downregulation of heat response in crowns. Comparison of chilling treatment on whole and part of the plants reveals that response to distal-chilling is very distinct from, and sometimes opposite to, response to local- or whole-plant chilling in both leaves and roots, suggesting a communication between shoots and roots in environmental perception. In sum, this study details chilling responses in leaves, roots and crowns and reveals potential chilling survival mechanism in maize, which lays ground for further understanding survival and tolerance mechanisms under low but non-freezing temperatures in tropical and subtropical plants.

Project description:To better understanding the genetic and physiological changes behind the dormancy process in tree peony, we performed customized cDNA microarray to investigate gene expression profiling in tree peony M-bM-^@M-^XFeng Dan BaiM-bM-^@M-^Y buds during chilling induced dormancy release. Endo-dormant tree peony plants were exposed to 0-4M-BM-0C from 5 November to 30 December 2009 in Qingdao, Shandong, China. Buds were collected after 0 d, 6 d, 12 d, 15 d, 18 d and 24 d chilling endured.

Expression of differentially-expressed genes associated with GA biosynthesis and signaling, cell growth and development was confirmed by quantitative RT-PCR, which displayed similar trends pattern in expression. Transcript profiling of tree peony was measured during chilling (0-4M-BM-0C) induced dormancy release. Mixed buds, three buds for each individual, were collected after 0, 6, 12, 15, 18 (endo-dormancy release), 24 days (eco-dormancy) chilling requirement fulfilling. Three replications (3 plants/ replication) were harvested between November and December.

Genome-wide comparative transcriptome profiling of two contrasting chilling tolerant rice genotypes in response to early chilling stress

Project description:To understand the molecular mechanisms underlying chilling tolerance in rice, transcriptomic deep sequencing was performed to reveal the differentially expressed genes between chilling tolerance chromosome substitution line (CSL), DC90 and its chilling-sensitive recurrent parent 9311 under early chilling stress events. Our results revealed a set of DEGs with higher basal expression in DC90 by comparison with 9311. They were functionally enriched in GO terms, such as, response to stress, response to stimulus, and response to abiotic stimulus, suggesting their positive role in intrinsic chilling tolerance. Common up-regulated and down-regulated DEGs were enriched in 26 and 34 GO terms, including response to stimulus, response to stress, and response to abiotic stimulus, respectively. Furthermore, comparative transcriptomic analysis between DC90 and 9311 in response to early chilling stress revealed 502 DEGs specifically identified in DC90. Most of gene loci were located beyond introgressed regions, implying that the introgression led to reprogramming of transcriptome in response to early chilling stress. CARMO platform analysis of these DEGs presented a complex regulatory network, including phytohormone signaling, photosynthesis pathway, that coordinately involved in chilling tolerance response of DC90. Here, the unveiled molecular regulatory network shed light on deep understanding the mechanisms of rice chilling tolerance. As well, chilling tolerant-QTLs and co-localized DEGs in introgressed fragments, will be focused for further functional investigation of the molecular mechanisms of early chilling stress response in rice.
