Comparative transcriptome analysis in Chinese cabbage ( Brassica rapa ssp. pekinesis) for DEGs of Ogura-, Polima-CMS and their shared maintainer. PHYSIOLOGY AND MOLECULAR BIOLOGY OF PLANTS : AN INTERNATIONAL JOURNAL OF FUNCTIONAL PLANT BIOLOGY 2020; 26:719-731.

Abstract
Cytoplasmic male sterility (CMS) is maternally inherited trait, which hinders the ability to produce viable pollen in plants. It serves as a useful tool for hybrid seed production via exploiting heterosis in crops. The molecular mechanism of CMS and fertility restoration has been investigated in different crops. However, limited number of reports is available on comparison of Ogura- and Polima-CMS with their shared maintainer in Chinese cabbage. We performed transcript profiling of sterile Ogura CMS (Tyms), Polima CMS (22m2) and their shared maintainer line (231-330) with an aim to identify genes associated with male sterility. In this work, we identified 912, 7199 and 6381 DEGs (Differentially Expressed Genes) in 22m2 Vs Tyms, 231-330 VS 22m2 and 231-330 Vs Tyms, respectively. The GO (Gene Ontology) annotation and KEGG pathway analysis suggested that most of the DEGs were involved in pollen development, carbon metabolism, lipase activity, lipid binding, penta-tricopeptide repeat (PPR), citrate cycle and oxidative phosphorylation, which were down-regulated in both CMS lines. This result will provide an important resource for further understanding of functional pollen development, the CMS mechanism and to improve molecular breeding in Chinese cabbage.

Abstract
Dipeptidyl peptidase-4 (DPP-4) inhibitors are a well-known and novel class of oral antihyperglycaemic drugs. DPP-4 inhibition facilitates ulcer healing in patients with diabetes. However, the actual mechanisms, which are independent of lower blood glucose levels, are still unknown. Therefore, the aim of this study was to analyse the effect of the DPP-4 inhibitor sitagliptin on wound healing through a glucose-independent pathway. In this study, DPP-4 inhibitors facilitate keratinocyte differentiation and the proliferation, increase blood flow in the cutaneous of wounds in healthy C57BL/6 mice. Additionally, the administration of the DPP-4 inhibitor ameliorates wound healing and enhances adiponectin expression in healthy C57BL/6 mice. Taken together, our results reveal a protective role for the DPP-4 inhibitor sitagliptin in wound healing by regulating adiponectin and phospho-eNOS levels in keratinocytes. Based on these results, the DPP-4 inhibitor may have therapeutic potential for healing wounds through a diabetes-independent mechanism.

Abstract
Tissue-specific miRNAs (TS miRNA) specifically expressed in particular tissues play an important role in tissue identity, differentiation and function. However, transcription factor (TF) and TS miRNA regulatory networks across multiple tissues have not been systematically studied. Here, we manually extracted 116 TS miRNAs and systematically investigated the regulatory network of TF-TS miRNA in 12 human tissues. We identified 2,347 TF-TS miRNA regulatory relations and revealed that most TF binding sites tend to enrich close to the transcription start site of TS miRNAs. Furthermore, we found TS miRNAs were regulated widely by non-tissue specific TFs and the tissue-specific expression level of TF have a close relationship with TF-genes regulation. Finally, we describe TSmiR (http://bioeng.swjtu.edu.cn/TSmiR), a novel and web-searchable database that houses interaction maps of TF-TS miRNA in 12 tissues. Taken together, these observations provide a new suggestion to better understand the regulatory network and mechanisms of TF-TS miRNAs underlying different tissues.

Abstract
Hydrophobic storage neutral lipids are stably preserved in specialized organelles termed oil bodies in the aqueous cytosolic compartment of plant cells via encapsulation with surfactant molecules including phospholipids and integral proteins. To date, three classes of integral proteins, termed oleosin, caleosin, and steroleosin, have been identified in oil bodies of angiosperm seeds. Proposed structures, targeting traffic routes, and biological functions of these three integral oil-body proteins were summarized and discussed. In the viewpoint of evolution, isoforms of oleosin and caleosin are found in oil bodies of pollens as well as those of more primitive species; moreover, caleosin- and steroleosin-like proteins are also present in other subcellular locations besides oil bodies. Technically, artificial oil bodies of structural stability similar to native ones were successfully constituted and seemed to serve as a useful tool for both basic research studies and biotechnological applications.

The tissue expression pattern of the AtGRP5 regulatory region is controlled by a combination of positive and negative elements. PLANT CELL REPORTS 2010; 29:461-71. [PMID: 20195610 DOI: 10.1007/s00299-010-0835-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/10/2009] [Revised: 02/03/2010] [Accepted: 02/09/2010] [Indexed: 05/20/2023]
Abstract
The AtGRP5 gene from Arabidopsis thaliana encodes a glycine-rich protein which has a major activity in protoderm-derived cells and is expressed in cells that undergo the first anatomical modifications leading to somatic embryo development. It has been previously demonstrated that its minimum promoter is 316 bp long including the 5'UTR and presents three putative TATA-boxes sequences and several regions that are homologous to previous characterized cis-acting elements. In order to better characterize the AtGRP5 expression and to identify the promoter regions involved in its preferential epidermal expression, in situ hybridization and 5' promoter deletions were employed. In situ hybridization and GUS expression assays indicate that, besides being present during somatic embryogenesis, AtGRP5 is also expressed during the zygotic embryo development. The sequential 5' deletions indicate that multiple negative and positive regulatory elements are present in the AtGRP5 promoter and operate in order to confer its distinct expression pattern. A 44-bp region was shown to be essential for the epidermal expression of this gene in leaves, stems, flowers and fruits, and is also responsible for high activity of the AtGRP5 promoter in zygotic embryos. An element responsible for the phloem expression was also identified in a 35-bp region.

Abstract
Stable oil bodies of smaller sizes and higher thermostability were isolated from mature cycad (Cycas revoluta) megagametophytes compared with those isolated from sesame seeds. Immunological cross-recognition revealed that cycad oil bodies contained a major protein of 27 kDa, tentatively identified as caleosin, while oleosin, the well-known structural protein, was apparently absent. Mass spectrometric analysis showed that the putative cycad caleosin possessed a tryptic fragment of 15 residues matching to that of a theoretical moss caleosin. A complete cDNA fragment encoding this putative caleosin was obtained by PCR cloning using a primer designed according to the tryptic peptide and another one designed according to a highly conservative region among diverse caleosins. The identification of this clone was subsequently confirmed by immunodetection and MALDI-MS analyses of its recombinant fusion protein over-expressed in Escherichia coli and the native form from cycad oil bodies. Stable artificial oil bodies were successfully constituted with triacylglycerol, phospholipid and the recombinant fusion protein containing the cycad caleosin. These results suggest that stable oil bodies in cycad megagametophytes are mainly sheltered by a unique structural protein caleosin.

Abstract
Stable oil bodies were purified from mature lily (Lilium longiflorum Thunb.) pollen. The integrity of pollen oil bodies was maintained via electronegative repulsion and steric hindrance possibly provided by their surface proteins. Immunodetection revealed that a major protein of 18 kDa was exclusively present in pollen oil bodies and massively accumulated in late stages of pollen maturation. According to mass spectrometric analyses, this oil body protein possessed a tryptic fragment of 13 residues matching that of a theoretical rice oleosin. A complete cDNA fragment encoding this putative oleosin was obtained by PCR cloning with primers derived from its known 13-residue sequence. Sequence analysis as well as immunological non-cross-reactivity suggests that this pollen oleosin represents a distinct class in comparison with oleosins found in seed oil bodies and tapetum. In pollen cells observed by electron microscopy, oil bodies were presumably surrounded by tubular membrane structures, and encapsulated in the vacuoles after germination. It seems that pollen oil bodies are mobilized via a different route from that of glyoxysomal mobilization of seed oil bodies after germination.

Abstract
I have used cellular and molecular genetic and bioinformatic approaches to characterise the components of the pollen coat in plants of the family Brassicaceae, including Arabidopsis thaliana and several brassicas including Brassica napus, B. oleracea, and B. rapa. The pollen coat in these species is mostly made up of a unique mixture of lipids that is highly enriched in acylated compounds, such as sterol esters and phospholipids. These acyl lipids are characterised by an unusually high degree of saturation. The fatty acids typically contain 70-90% saturated acyl residues such as myristate, palmitate, and stearate. The major sterol components of the pollen coat are saturated fatty acyl esters of stigmasterol, campesterol, and campestdienol. In addition to lipids, the second major component of the pollen coat is a specific group of proteins that is dominated by a family of proteins that we term pollenins. Although pollenins are by far the major protein components of the pollen coat of members of the Brassicaceae, proteomic analysis reveals that there are several additional protein components, including lipases, protein kinases, a pectin esterase, and a caleosin. The biosynthesis of these lipids and proteins and their significance for overall pollen function are reviewed and discussed.

Abstract
We identified the Arabidopsis MALE STERILITY1 (MS1) gene by transposon-mediated mutagenesis. In the transposon-inserted allele ms1-8, normal immature microspores separated from tetrads, but their subsequent maturation was abnormal: the outer layer of the microspore was absent, and both the microspore and the tapetal layer gradually became vacuolated. Empty locules resulted. The MS1 gene was expressed only in the tapetal layer during a very short period when the microspores were packed as tetrads. By the time the microspores had separated, the gene was no longer expressed. MS1 was not expressed in microspores. MS1 encodes a protein with a PHD-finger motif characteristic of some transcriptional regulators. A fusion protein consisting of the N-terminus of MS1 and green fluorescent protein was localized in the nucleus. These results suggest that MS1 protein is a nuclear signal molecule indispensable for pollen maturation.
