is a plant-pathogenic bacterium causing plant bacterial wilt, and can be strongly inhibited by methyl gallate (MG). Our previous transcriptome sequencing of MG-treated showed that the gene of Rs-T02 was up-regulated significantly under MG stress. In this study, a deletion mutant (named DM3545) and an over-expression strain (named OE3545) for were constructed to confirm this hypothesis.

In 2017, suspected bacterial wilt of was discovered in Qinzhou and Beihai, Guangxi, China. A variety of weeds are considered as reservoirs harboring bacterial wilt pathogens, but most do not show obvious symptoms in the field.

In this study, we set out to explore whether systemic inflammatory stress affects the development of retinal ganglion cells (RGCs). Neonatal inflammation was induced by single and systemic injection of lipopolysaccharide (LPS, 1 mg/kg) at postnatal day 4 (P4).

However, neuronal morphological changes under a depressive state have not been well understood yet. Here a depressive-like YFP-H transgenic mouse model was produced by light deprivation (LD), and morphological changes of retinal ganglion cells (RGCs) and primary visual and auditory cortical layer 5 pyramidal cells (L5PCs) were investigated.

It represents the most prevalent phylotype in Guangxi. Here, we present the draft genome sequence of this strain, which comprises 5,225 genes and 5,976,011 nucleotides with an average G+C content of 66.

Since the visual processing has shown abnormalities in these disorders, we explored whether neuropathologic changes can be caused in the primary visual cortex in offsprings due to the maternal inflammation induced by a single lipopolysaccharide (LPS) injection in pregnant mouse dams. The morphology and electrophysiological properties of layer II pyramidal cells (L2PC) in the primary visual cortex were investigated with whole-cell patch-clamping recording and 3D neuron reconstruction techniques.

Eight bacterial strains were isolated from affected banana leaves, and identified as an intraspecific taxon of Agrobacterium vitis based on their 16S rDNA sequence similarities with those of 37 randomly selected bacterial strains registered in GenBank database. The representative strain Ag-1 was virulent on banana leaves and shared similar growth and biochemical reactions with the reference strain IAM14140 of A.

One compound responsible for the antibacterial activity was isolated from the ethyl ether extract and identified as methyl gallate (MG) based on its H and C nuclear magnetic resonance data as well as mass spectroscopy. MG displayed broad-spectrum activity against plant-pathogenic bacteria, and strong inhibitory effects on the growth of plant-pathogenic oomycetes.
