miR390 family of Cymbidium goeringii is involved in the development of reproductive organs in transgenic Arabidopsis.

Background: miR390s is an ancient family with a high level of conservation among plant miRNAs. Through the auxin signal transduction pathway, miR390 participates in diverse biological processes of plant growth and development. As an important Chinese traditional orchid, Cymbidium goeringii has unique flower shape and elegant fragrance.

Functional analysis of from in IAA response during leaf development.

Background: is an economically important genus of flowering orchids cultivated in China because of showing graceful leaf shapes and elegant flower coloration. However, the deterioration of the ecological environment and the difficulty of conservation management have become increasing challenges for maintaining its germplasm resources. ARFs are critical transcription factors in the auxin signaling pathway and have been found to play pivotal roles in leaf growth and development in previous studies.

[Advances in the research of microRNA in Orchidaceae].

As a class of small non-coding RNAs, microRNA (miRNA) is widely present and plays important regulatory roles in plant growth, development and stress response. Based on the mechanism of miRNAs in plants, we review the identification of miRNAs in some genera of Orchidaceae, the specific functions of several miRNAs and other relevant studies on miRNAs in the last decade, in order to provide a reference for better understanding function and regulatory network of small RNAs in orchids.

The bayberry database: a multiomic database for Myrica rubra, an important fruit tree with medicinal value.

Background: Chinese bayberry (Myrica rubra Sieb. & Zucc.) is an important fruit tree in China, and has high medicinal value.

Functional analysis of from in ABA response.

Background: The orchid is one of the top ten Chinese flowers and has high ornamental value and elegant color. However, orchids are vulnerable to abiotic stresses during their growth and development, and the molecular mechanism of the abiotic stress response in orchids is unclear. WRKY proteins belong to a transcription factor family that plays important roles in biotic stress, abiotic stress, growth and development in plants, but little is known about the WRKY family in .

The identification of key candidate genes mediating yellow seedling lethality in a Lilium regale mutant.

Leaf color mutants are ideal materials for exploring plant photosynthesis mechanisms, chlorophyll biosynthetic pathways and chloroplast development. The yellow seedling lethal mutant lrysl1 was discovered from self-bred progenies of Lilium regale; however, the mechanism of leaf color mutation remains unclear. In this study, the ultrastructural and physiological features and de novo RNA-Seq data of a L.

Selection of reference genes for quantitative real-time PCR analysis of photosynthesis-related genes expression in .

Photosynthesis is closely related to the growth of plants. A stable reference gene is fundamental for studies of the molecular mechanism of photosynthesis in . Therefore, it is very important to select a suitable reference gene for qRT-PCR analysis on genes of photosynthetic system, chlorophyll biosynthetic pathway and chloroplast development in .

Elucidation of the mechanism of reflowering in tree peony (Paeonia suffruticosa) 'Zi Luo Lan' by defoliation and gibberellic acid application.

In this study, the reflowering mechanism of tree peony (Paeonia suffruticosa 'Zi Luo Lan') after defoliation and gibberellic acid (GA) application (autumn-flowering treatment) was investigated by monitoring the morphological changes, measuring the endogenous GA and abscisic acid (ABA) contents, and determining the expression patterns of six GA- and two ABA-related genes. The results show that autumn-flowering treatment induced tree peony reflowering in autumn, which was accompanied by nutrient absorption in buds. The application of exogenous GA induced a simultaneous increase in GA and decrease in ABA levels, suggesting that the high ratios of GA/ABA may play a key role in inducing tree peony reflowering.

Prevalence of Budd-Chiari Syndrome during Pregnancy or Puerperium: A Systematic Review and Meta-Analysis.

Women during pregnancy or puerperium are likely to develop Budd-Chiari syndrome (BCS). However, the reported prevalence of pregnancy-related BCS varied considerably among studies. Our study aims to systematically review this issue.

Novel insights into the development of portal vein thrombosis in cirrhosis patients.

The prognostic impact of portal vein thrombosis (PVT) in liver cirrhosis remains controversial among studies, primarily because the risk stratification of PVT is often lacking. A definition of clinically significant PVT should be proposed and actively improved. Moreover, the risk factors for the development of PVT in liver cirrhosis should be fully recognized to screen and identify high-risk patients.

SOX2, a predictor of survival in gastric cancer, inhibits cell proliferation and metastasis by regulating PTEN.

Inconsistent results of SOX2 expression have been reported in gastric cancer (GC). Here, we demonstrated that SOX2 was progressively downregulated during GC development via immunochemistry in 755 human gastric specimens. Low SOX2 levels were associated with pathological stage and clinical outcome.

MicroRNA let-7f inhibits tumor invasion and metastasis by targeting MYH9 in human gastric cancer.

Background: MicroRNAs (miRNAs) are important regulators that play key roles in tumorigenesis and tumor progression. A previous report has shown that let-7 family members can act as tumor suppressors in many cancers. Through miRNA array, we found that let-7f was downregulated in the highly metastatic potential gastric cancer cell lines GC9811-P and SGC7901-M, when compared with their parental cell lines, GC9811 and SGC7901-NM; however, the mechanism was not clear.
