Project description:Water lily is an important ornamental flower plant which is capable of viviparous plantlet development. But no study has been reported on the molecular basis of viviparity in water lily. Hence, we performed a comparative transcriptome study between viviparous water lily Nymphaea micrantha and a nonviviparous species Nymphaea colorata at four developmental stages. The higher expression of highly conserved AUX/IAA, ARF, GH3, and SAUR gene families in N. micrantha compared to N. colorata is predicted to have a major impact on the development and evolution of viviparity in water lily. Likewise, differential regulation of hormone signaling, brassinosteroid, photosynthesis, and energy-related pathways in the two species provide clues of their involvement in viviparity phenomenon. This study revealed the complex mechanism of viviparity trait in water lily. The transcriptomic signatures identified are important basis for future breeding and research of viviparity in water lily and other plant species.

Project description:Characterizing a common cellular stress response (CSR) to high water temperature across species and populations is necessary for identifying the capacity of Pacific salmon (Oncorhynchus spp.) to persist in current and future climate warming scenarios, especially for populations at the southern periphery of their species' distributions. In this study, populations of wild adult pink (O. gorbuscha) and sockeye (O. nerka) salmon from the Fraser River, British Columbia, Canada, were experimentally treated to an ecologically relevant 'cool' or 'warm' water temperature to uncover common transcriptomic responses to elevated water temperature.

Ninety-eight samples from three separate temperature exposure studies were analyzed on ninety-eight microarrays, using a common reference design, with multiple biological replicates for each temperature condition for each year of the experiment.

Project description:Drought has become an increasingly important constraint on grapevine sustainability due to global climate change. Vitis riparia, the only grapevine native to the upper Midwest region of the United States, is widely used in scion and rootstock breeding; however, it is not considered drought tolerant. In this study, RNA-Seq data were generated from grapevine root/shoot under WD and well-watered (control (C)) conditions to compare root signaling and shoot responses to water deficit.

Project description:Alhagi sparsifolia Shap. is a perennial subshrub belonging to genus Alhagi, family Leguminosae. As a typical desert phreatophyte, this plant species has highly developed deep roots and displays a great capacity to withstand poor soil as well as extreme dry, cold and hot weather. A. sparsifolia is naturally distributed in the arid and salinized regions of northernwestern China and adjacent countries in Central Asia, and plays a fundamental role in maintaining the local ecosystem. In addition, this plant is usually used as a fodder for local animals due to its high protein content, and is important in the development of local livestock husbandry. Considering its great tolerance to harsh environments, A. sparsifolia represents an ideal species for deciphering the mechanism of plant adaption to abiotic stress, such as water deficit. However, understanding the stress adaption in this plant is limited. While a few studies were conducted on physiological responses of A. sparsifolia to water stress, research has never been done to explore the genomic basis for its drought-tolerance to date. In particular, as a non-model plant species, the genomic resource of A. sparsifolia is rather scarce, only one expressed sequence tag (EST) and one protein have been deposited in Genbank prior to Sept., 2014. In aim to explore the genetic basis underlying drought tolerance in this species, recently we took advantage of transcriptome sequencing to survey the water stress responsive genes in A. sparsifolia primary roots. Using Illumina HiSeq™ 2000 platform, we sequenced the primary root samples individually collected at four different time points (0, 6h, 24 and 30h) from A. sparsifolia seedlings during 24h of water stress following 6h of rehydration. The resulting 38,763,230, 67,511,150, 49,259,804 and 54,744,906 high quality reads were pooled and assembled into 33,255 unigenes with an average length of 1,057 bp. All-unigenes were subjected to functional annotation by searching against the public databases including NR, NT, Swiss-Prot, Pfamm, GO, KOG and KEGG. On the basis of the established transcriptome database, we evaluated the gene expression profiles in A. sparsifolia primary roots at 0, 6, 24 and 30h in the course of water stress and subsequent rehydration. An extensive repertoire of the differently expressed genes (DEGs) reflecting the early response to water stress (6h), the late response to water stress (24h) and the response to post stress rehydration (30h) were identified. In addition, to unravel the dynamic changes of gene expression during water stress and subsequent rehydration, we further captured the DEGs commonly or specifically regulated at 6, 24 and 30h. Functional categorization of the DEGs disclosed the activation of oxidoreductase system in A. sparsifolia primary roots upon water stress, and particularly emphasized the significance of the ‘Glutathione metabolism pathway’. To our knowledge, this is the first description of the genetic makeup of A. sparsifolia, thus providing a substantial contribution to the sequence resources for this species. The DEGs identified herein offers a deep insight into the molecular mechanism of A. sparsifolia in response to water stress, and merits further investigation.
