Molecular mechanism of mulberry response to drought stress revealed by complementary transcriptomic and iTRAQ analyses.

Background: The use of mulberry leaves has long been limited to raising silkworms, but with the continuous improvement of mulberry (Morus alba) resource development and utilization, various mulberry leaf extension products have emerged. However, the fresh leaves of mulberry trees have a specific window of time for picking and are susceptible to adverse factors, such as drought stress. Therefore, exploring the molecular mechanism by which mulberry trees resist drought stress and clarifying the regulatory network of the mulberry drought response is the focus of the current work.

Whole genome bisulfite sequencing methylome analysis of mulberry (Morus alba) reveals epigenome modifications in response to drought stress.

DNA methylation plays a significant role in many biological processes. Although some studies of DNA methylation have been performed in woody plant, none is known about the methylation patterns of mulberry (Morus alba). In this study, we performed whole genome bisulfite sequencing under drought stress to generate a methylated cytosines map and assessed the effects of the changes on gene expression combined with transcriptomics.

Application of mass spectrometry in silkworm research-Review.

In this first mass spectrometry-focused review paper, we will review current applications of mass spectrometry in the area of silkworm research. We will focus our review on the following two most important areas as they are currently being researched by scientists. Firstly, the proteomics of proteins in the process of silkworm lifecycle has generated knowledge about previous undetected proteins, some of which might possess therapeutic effects.

Mulberry (Morus alba) MmSK gene enhances tolerance to drought stress in transgenic mulberry.

Shaggy-like protein kinase (SK) plays important roles in the plant growth development, signal transduction, abiotic stress and biotic stress and substance metabolism regulation. However, the exact function of the response to drought stress in mulberry with SK remains unclear. In this study, a new SK gene that was designated as MmSK (GenBank accession NO: KY348867) was isolated and cloned from mulberry (Morus alba).

Selenite Reduction and the Biogenesis of Selenium Nanoparticles by Se03 Isolated from the Gut of (Coleoptera: Cerambycidae).

In this study, a bacterial strain exhibiting high selenite (Na₂SeO₃) tolerance and reduction capacity was isolated from the gut of larvae and identified as Se03. The isolate exhibited extreme tolerance to selenite (up to 120 mM) when grown aerobically. In the liquid culture medium, it was capable of reducing nearly 100% of 1.

Aluminum toxicity related to SOD and expression of presenilin and CREB in Bombyx mori.

Aluminum (Al) is an important environmental metal factor that can be potentially associated with pathological changes leading to neurotoxicity. The silkworm, Bombyx mori, is an important economic insect and has also been used as a model organism in various research areas. However, the toxicity of Al on silkworm physiology has not been reported.

A palmitoyltransferase Approximated gene Bm-app regulates wing development in Bombyx mori.

The silkworm Bombyx mori is an important lepidopteran model insect in which many kinds of natural mutants have been identified. However, molecular mechanisms of most of these mutants remain to be explored. Here we report the identification of a gene Bm-app is responsible for the silkworm minute wing (mw) mutation which exhibits exceedingly small wings during pupal and adult stages.

High throughput deep degradome sequencing reveals microRNAs and their targets in response to drought stress in mulberry (Morus alba).

MicroRNAs (miRNAs) play important regulatory roles by targeting mRNAs for cleavage or translational repression. Identification of miRNA targets is essential to better understanding the roles of miRNAs. miRNA targets have not been well characterized in mulberry (Morus alba).
