Background: Flower buds of Anthurium andraeanum frequently cease to grow and abort during the early flowering stage, resulting in prolonged planting times and increased commercialization costs. Nevertheless, limited knowledge exists of the mechanism of flower development after initiation in A. andraeanum.

Finding reliable diagnostic biomarkers and therapeutic targets for HCC is highly desired in the clinic. Currently, circulating exosomal lncRNA is a promising biomarker for the diagnosis of cancer and lncRNA is also a potential target in cancer therapy.
View Article and Find Full Text PDFAngiogenesis is necessary for carcinoma progression and is regulated by a variety of pro- and anti-angiogenesis factors. CircRNAs are RNA molecules that do not have a 5'-cap or a 3'-polyA tail and are involved in a variety of biological functions. While circRNA-mediated regulation of tumor angiogenesis has received much attention, the detailed biological regulatory mechanism remains unclear.

In this study, we identified 11 miR156- and 5 miR157-encoding loci from the genome of Petunia axillaris and Petunia inflata, designated as PaMIR0156/157s and PiMIR0156/157s, respectively. Real-time quantitative reverse transcription PCR (qRT-PCR) analysis indicated that PhmiR156/157 was expressed predominantly in cotyledons, germinating seeds, flower buds, young fruits and seedlings.
View Article and Find Full Text PDFThe mechanism that coordinates cell growth and cell cycle progression remains poorly understood; in particular, whether the cell cycle and cell wall biosynthesis are coordinated remains unclear. Recently, cell wall biosynthesis and cell cycle progression were reported to respond to wounding. Nonetheless, no genes are reported to synchronize the biosynthesis of the cell wall and the cell cycle.

MicroRNAs and transcription factors (TFs) cooperate to regulate the same target gene, thus affecting the progression of HCC.
Methods: Differentially expressed miRNAs and mRNAs were screened.
Small heat shock proteins (sHSPs) increase stress tolerance in a wide variety of organisms and enable them to endure changes in their environment. However, the molecular mechanism by which sHSPs protect plants against cold stress is unknown. Here, the sHSP of tomato named SlHSP17.
View Article and Find Full Text PDFFlavonoids play critical roles in plant responses to various stresses. Few studies have been reported on what the mechanism of activating flavonoid biosynthesis in plant responses to wounding and oxidation is. In this study, flavonoid metabolites and many MYB transcript factors from Rosa rugosa were verified to be induced by wounding and oxidation.
View Article and Find Full Text PDFFruit quality formation involves a series of physiological and biochemical changes during fruit ripening. Sucrose metabolism plays not only important roles in fruit ripening to establish energy status and nutritional quality but also a non-nutritive role in gene expression. In carbon metabolism and fruit ripening, cell wall invertases (CWINs) perform essential regulatory functions.

Methods: Six-leaf-stage tomato seedlings ("Liaoyuanduoli", n=160) were divided into four parts: Part 1, served as control under 25 °C, 500 µmol/(m·s); Part 2, spayed with distilled water (HO) under 35 °C, 1000 µmol/(m·s) (HH); Part 3, spayed with 100 µmol/L diuron (DCMU, CEF inhibitor) under HH; Part 4, spayed with 60 µmol/L methyl viologen (MV, LEF inhibitor) under HH. Energy conversion, photosystem I (PSI), and PSII activity, and trans-thylakoid membrane proton motive force were monitored during the treatment of 5 d and of the recovering 10 d.
