Powdery mildew (PM), which is mainly caused by , is a serious biotrophic pathogen disease affecting field-grown and greenhouse-grown cucurbit crops worldwide. Because fungicides poorly control PM, the development and cultivation of PM-resistant varieties is critical. A homolog of (), which encodes a key component of the plant disease-associated signal transduction pathway, was previously identified through a transcriptomic analysis of a PM-resistant pumpkin () inbred line infected with PM.

Cucurbit powdery mildew (PM) is one of the most severe fungal diseases, but the molecular mechanisms underlying PM resistance remain largely unknown, especially in pumpkin (Cucurbita moschata Duch.). The goal of this study was to identify gene expression differences in PM-treated plants (harvested at 24 h and 48 h after inoculation) and untreated (control) plants of inbred line "112-2" using RNA sequencing (RNA-Seq).

Article Synopsis
  • The study identifies a new NAC transcription factor called CaNAC2 from Capsicum annuum, which is similar to a protein from Petunia and plays a role in plant development and stress regulation.
  • CaNAC2 has a conserved NAC domain at its N-terminus and is mainly expressed in seeds and roots, with its expression increasing in response to cold, salt, and ABA treatments.
  • Silencing CaNAC2 makes pepper seedlings more susceptible to cold stress and hampers leaf chlorophyll degradation under salt stress, suggesting its crucial role in abiotic stress tolerance in peppers.

Although guidelines and formulas have been developed through clinical practice to define infusion rate and volume, over- and under-resuscitation are still common, followed by increasing morbidity and mortality. In order to establish an effective management for early fluid resuscitation, the clinical decision support system (CDSS) has been established. The CDSS, by utilizing information systems coupled with decision support technology, could provide recommendations for the amount of fluid to be infused based on measured biological response.

A study was carried out on the characteristic of lead absorption in pumpkin via atomic absorption spectrophotometer. The results showed that lead absorption amount in pumpkin increased with time, but the absorption rate decreased with time; And the lead absorption amount reached the peak in pH 7. Lead and cadmium have similar characteristic of absorption in pumpkin.

Objective: To investigate the different expressions of cytoskeletal organizer ezrin and cytoskeleton protein beta- and gamma-actin in hepatocellular carcinoma (HCC) cell lines with different metastatic potentials and to explore the role of ezrin in cell growth and metastasis in HCC cell lines SF7721 and MHCC97-H.

Methods: Immunofluorescence, RT-PCR and Western blot were used to detect the gene and protein expressions of ezrin and actin in hepatocellular carcinoma cell lines with different metastatic potentials. RNA interference (RNAi) was applied to down-regulate the ezrin expression in SF7721 and MHCC97-H.

Objective: To investigate the effect of membrane-cytoskeleton linker ezrin on the growth and metastasis of human hepatocellular carcinoma cell (HCC) lines.

Methods: Human HCC cells of the lines SF/SMMC7721, MHCC97-H, MHCC-1, and HepG2 were cultured. Four pairs of small interfering RNA (siRNA) targeting erzin were designed and transfected into the HCC cells.

Objectives: To explore the influence of c-Met inhibitor by synthetic c-Met antisense oligonucleotide, constructive c-Met antisense plasmid and the complex plasmid of U1SnRNA/ ribozyme/anti-Met on the growth and metastasis of hepatocellular carcinoma cells.

Methods: Gene transfection was operated by Lipofectin on SF7721 cells. The difference of the cells before and after transfection was compared by MTT, growth curves and transwell test in vitro.
