Project description:To identify key genes in the regulation of salt tolerance in the mangrove plant Bruguiera gymnorhiza, the transcriptome profiling under salt stress was carried out. Main roots and lateral roots were collected from the mangrove plants at 0, 1, 3, 6, 12 and 24 h, 3 6 and 12 days after NaCl-treatment. Keywords: time course, stress response, root type comparison

Project description:Flowering of Arabidopsis thaliana is accelerated by several environmental cues, including exposure to long days. The photoperiod-dependent promotion of flowering involves the transcriptional induction of FLOWERING LOCUS T (FT) in the phloem of the leaf. FT encodes a mobile protein that is transported from the leaves to the shoot apical meristem, where it forms part of a regulatory complex that induces flowering. Whether FT also has biological functions in leaves of wild-type plants remains unclear. In order to address this issue, we first studied the leaf transcriptomic changes associated with its over expression in the companion cells of the phloem. To this end, transgenic A. thaliana plants that misexpress FT from the pGAS1 promoter in a ft-10 tsf-1 double mutant background were employed (pGAS1:FT ft-10 tsf-1). In these transgenic plants, the use of the pGAS1 promoter ensures that the FT transgene is expressed in phloem companion cells of the minor veins, recreating the spatial pattern of expression described for the native gene. In this studuy, the transcriptome of leaves of pGAS1:FT ft-10 tsf-1 transgenic plants was compared to that of ft-10 tsf-1 and Col-0 plants using Tiling Arrays.

Project description:Despite its significance to reproduction, fertility, sexually transmitted infections and various pathologies, the fallopian tube (FT) is relatively understudied. Strong evidence points to the FT as the tissue-of-origin of high grade serous ovarian cancer (HGSOC), the most fatal gynaecological malignancy. HGSOC precursor lesions arise specifically in the distal FT (fimbria) which is reported to be enriched in stem-like cells. Investigation of the role of FT stem cells in health and disease has been hampered by a lack of characterization of FT stem cells and lack of models that recapitulate stem cell renewal and differentiation in vitro. Using optimized organoid culture conditions to address these limitations, we found that FT stem cell renewal is highly dependent on WNT/β-catenin signaling and engineered endogenous WNT/β-catenin signaling reporter organoids to biomark, isolate and characterize putative FT stem cells. Using functional approaches as well as bulk and single cell transcriptomic analyses, we show that an endogenous hormonally-regulated WNT7A-FZD5 signaling axis is critical for self-renewal of human FT stem cells, and that WNT/β-catenin pathway-activated cells form a distinct transcriptomic cluster of FT cells enriched in ECM remodelling and integrin signaling pathways. In addition, we find that the WNT7A-FZD5 signaling axis is dispensable for mouse oviduct regeneration. Overall, we provide a deep characterization of FT stem cells and their molecular requirements for self-renewal, paving the way for mechanistic work investigating the role of stem cells in FT health and disease.

Main roots and lateral roots were collected from the mangrove plants at 0, 1, 3, 6, 12 and 24 h, 3 6 and 12 days after NaCl-treatment. Samples were collected from each set of three trees at 0, 1, 3, 6, 12 and 24 h, 3 6 and 12 days after NaCl-treatment, that is 27 trees were used in total. RNA was extracted from mixture of the samples from 3 trees to average genotypes of 3 trees.
