Tonoplast proton pumps regulate nuclear spacing of female gametophytes mediating polar auxin transport in .

The vacuole is an important organelle with multiple functions in plants, and the tonoplast that wraps the vacuole also plays essential roles in intracellular trafficking and ion homeostasis. Previous studies found that tonoplast proton pumps regulate embryo development and morphogenesis through their effects on vacuole biogenesis and distribution, as well as polar auxin transport and concomitant auxin gradient. However, the precise roles of the tonoplast proton pumps in gametophyte development remain unclear.

PIN3 positively regulates the late initiation of ovule primordia in Arabidopsis thaliana.

Ovule initiation determines the maximum ovule number and has great impact on seed number and yield. However, the regulation of ovule initiation remains largely elusive. We previously reported that most of the ovule primordia initiate asynchronously at floral stage 9 and PINFORMED1 (PIN1) polarization and auxin distribution contributed to this process.

[Effects of miR-203a targeting and its target gene on lymph node metastasis of breast cancer].

To study the expression and correlation of mir-203a and its target gene ATM in breast cancer tissues, so as to provide theoretical basis for the pathogenesis of breast cancer, especially lymph node metastasis. Thirty paired breast cancer and paracancer normal tissues were collected, and RT-qPCR was used to detect the relative expression levels of mir-203a and ATM in the samples of the two groups. Correlation analysis was conducted for mir-203a and ATM, and correlation analysis was conducted for the pathological characteristics, so as to compare whether there were statistical differences between mir-203a and ATM in lymph node metastasis and non-metastasis.

FRS: A simple knowledge graph embedding model for entity prediction.

Entity prediction is the task of predicting a missing entity that has a specific relation-ship with another given entity. Researchers usually use knowledge graphs embedding(KGE) methods to embed triples into continuous vectors for computation and perform the tasks of entity prediction. However, KGE models tend to use simple operations to refactor entities and relationships, resulting in insufficient interaction of components of knowledge graphs (KGs), thus limiting the performance of the entity prediction model.

Effects of Agitation, Aeration and Temperature on Production of a Novel Glycoprotein GP-1 by Streptomyces kanasenisi ZX01 and Scale-Up Based on Volumetric Oxygen Transfer Coefficient.

The effects of temperature, agitation and aeration on glycoprotein GP-1 production by ZX01 in bench-scale fermentors were systematically investigated. The maximum final GP-1 production was achieved at an agitation speed of 200 rpm, aeration rate of 2.0 vvm and temperature of 30 °C.

Optimization of Fermentation Conditions and Bench-Scale for Improvement of a Novel Glycoprotein GP-1 Production by Streptomyces kanasenisi ZX01.

GP-1 is a novel glycoprotein produced by ZX01 that was isolated from soil near Kanas Lake with significant bioactivity against tobacco mosaic virus. However, extremely low fermentation production has largely hindered further research and market applications on glycoprotein GP-1. In this study, response surface methodology was used to optimize fermentation conditions in a shake flask for higher glycoprotein GP-1 production.

Antifungal Activity and Action Mode of Cuminic Acid from the Seeds of Cuminum cyminum L. against Fusarium oxysporum f. sp. Niveum (FON) Causing Fusarium Wilt on Watermelon.

In order to develop a novel biofungicide, the antifungal activity and action mode of cuminic acid from the seed of L. against f. sp.

Two new Anti-TMV active chalconoid analogues from the root of Phyllanthus emblica.

Two new chalconoid analogues, emblirol A (1) and B (2), along with three known ones (3-5), were isolated from the root of the Phyllanthus emblica L. Their structures were elucidated on the basis of spectral data. Compound 1 and 2 showed moderate anti-TMV activity with inhibition rates 79.

Potential use of cuminic acid as a botanical fungicide against Valsa mali.

Valsa canker caused by Valsa mali is commonly present in eastern Asia and cause large economic losses. Because of limited agricultural measures and chemical residues of commonly used fungicides there is an urgent need of alternative plant protecting agents. On this background the activity of cuminic acid, a plant extract from the seed of Cuminum cyminum L, was assessed.

Optimization of medium compositions to improve a novel glycoprotein production by Streptomyces kanasenisi ZX01.

Streptomyces kanasenisi ZX01 was found to produce a novel glycoprotein GP-1 previously, which was secreted into medium and had significant activity against tobacco mosaic virus. However, the low production of GP-1 by strain ZX01 limited its further studies. In order to improve the yield of GP-1, a series of statistical experimental design methods were applied to optimize medium of strain ZX01 in this work.

Immunomodulatory activity of macromolecular polysaccharide isolated from Grifola frondosa.

The present study was designed to evaluate the immune-modulating effects of the polysaccharide from Grifola frondosa (GFP) by using mouse peritoneal macrophage and cytoxan (CTX) induced immunosuppression models. Our results from the phagocytotic and mononuclear phagocytic system function assays showed that GFP-A (one component from GFP) stimulated the phagocytosis of the phagocytes. The splenocyte proliferation assay showed that GFP-A acted the effect combing ConA or LPS in splenocyte proliferation.

Effects of plant stress signal molecules on the production of wilforgine in an endophytic actinomycete isolated from Tripterygium wilfordii Hook.f.

The endophytic actinomycete F4-20 was isolated from Tripterygium wilfordii Hook.f. and was confirmed to produce wilforgine, a secondary metabolite discovered in its host.

Biological Control of Apple Ring Rot on Fruit by Bacillus amyloliquefaciens 9001.

Synthesis, characterization, and antibacterial activity of cross-linked chitosan-glutaraldehyde.

This present study deals with synthesis, characterization and antibacterial activity of cross-linked chitosan-glutaraldehyde. Results from this study indicated that cross-linked chitosan-glutaraldehyde markedly inhibited the growth of antibiotic-resistant Burkholderia cepacia complex regardless of bacterial species and incubation time while bacterial growth was unaffected by solid chitosan. Furthermore, high temperature treated cross-linked chitosan-glutaraldehyde showed strong antibacterial activity against the selected strain 0901 although the inhibitory effects varied with different temperatures.

Statistical optimization of process variables for antibiotic activity of Xenorhabdus bovienii.

The production of secondary metabolites with antibiotic properties is a common characteristic to entomopathogenic bacteria Xenorhabdus spp. These metabolites not only have diverse chemical structures but also have a wide range of bioactivities of medicinal and agricultural interests. Culture variables are critical to the production of secondary metabolites of microorganisms.
