Specific Transcriptional Regulation Controls Plant Organ-Specific Infection by the Oomycete Pathogen Phytophthora sojae.

The organs of a plant species vary in cell structure, metabolism and defence responses. However, the mechanisms that enable a single pathogen to colonise different plant organs remain unclear. Here we compared the transcriptome of the oomycete pathogen Phytophthora sojae during infection of roots versus leaves of soybeans.

Effects of Tactile Massage in Improving Older Residents' Psychological Health in Long-Term Care Facilities: A Randomised Controlled Trial.

Background: Loneliness, anxiety and depressive symptoms are common among older residents in long-term care facilities (LTCFs), which can negatively impact their quality of life and increase mortality rates. Addressing these psychological health issues is an important task for nursing staff. There is a need for easy and accessible interventions to improve older residents' negative emotions.

Functional Characterization of the Histone Acetyltransferase in Lotus Rhizome Rot-Causing Fungus .

is the main pathogen of lotus rhizome rot, which causes the wilt of many plants. Histone acetyltransferase plays a critical part in the growth and virulence of fungi. In the present study, we identified an FcElp3 in homologous to histone acetyltransferase Elp3.

Multi-omics analysis revealed that the protein kinase MoKin1 affected the cellular response to endoplasmic reticulum stress in the rice blast fungus, Magnaporthe oryzae.

Background: Previous studies have shown that protein kinase MoKin1 played an important role in the growth, conidiation, germination and pathogenicity in rice blast fungus, Magnaporthe oryzae. ΔMokin1 mutant showed significant phenotypic defects and significantly reduced pathogenicity. However, the internal mechanism of how MoKin1 affected the development of physiology and biochemistry remained unclear in M.

Interaction of negative regulator OsWD40-193 with OseEF1A1 inhibits Oryza sativa resistance to Hirschmanniella mucronata infection.

Rice is a crucial food crop worldwide, but it is highly susceptible to Hirschmanniella mucronata, a migratory parasitic nematode. No rice variety has been identified that could resist H. mucronata infection.

Integrated transcriptome and metabolome analysis revealed that flavonoids enhanced the resistance of against .

Rice is a crucial food crop worldwide, but its yield and quality are significantly affected by is a root knot nematode. No rice variety is entirely immune to this nematode disease in agricultural production. Thus, the fundamental strategy to combat this disease is to utilize rice resistance genes.

The Phytophthora sojae nuclear effector PsAvh110 targets a host transcriptional complex to modulate plant immunity.

Plants have evolved sophisticated immune networks to restrict pathogen colonization. In response, pathogens deploy numerous virulent effectors to circumvent plant immune responses. However, the molecular mechanisms by which pathogen-derived effectors suppress plant defenses remain elusive.

First report of spotting disease caused by Fusarium proliferatum infection of Alisma orientale in China.

Alisma orientale (Alismatidae) is highly valued for both its pharmaceutical and nutritional properties. The tubers are in Chinese herbal medicine and the leaves and stems for several Chinese delicacies. Intercropping A.

Genome and Transcriptome Sequencing Analysis of Fusarium Provides Insights into the Pathogenic Mechanisms of the Lotus Rhizome Rot.

Fusarium wilt, a vascular wilt caused by , has been a serious problem for the lotus. Although some isolate genomes have been sequenced, little is known about the genomic information of the strain that causes Fusarium wilt of aquatic plants. In this study, the genome of FCN23 isolated from lotuses in China was sequenced using Illumina and PacBio sequencing platforms.

Identification and characterization of L-type lectin receptor-like kinases involved in Glycine max-Phytophthora sojae interaction.

Soybean contains a group of 64 L-type lectin receptor-like kinases. Three LecRKs were involved in the interactions with Phytophthora sojae and Bradyrhizobium diazoefficiens. L-type lectin receptor-like kinases (LecRKs) comprise an important class of membrane-localized receptor-like kinases that are involved in plant adaptation.

effector Avr1d functions as an E2 competitor and inhibits ubiquitination activity of GmPUB13 to facilitate infection.

Oomycete pathogens such as secrete a repertoire of effectors into host cells to manipulate host immunity and benefit infection. In this study, we found that an RxLR effector, Avr1d, promoted infection in soybean hairy roots. Using a yeast two-hybrid screen, we identified the soybean E3 ubiquitin ligase GmPUB13 as a host target for Avr1d.

Nglycosylation shields apoplastic effector PsXEG1 from a specific host aspartic protease.

Hosts and pathogens are engaged in a continuous evolutionary struggle for physiological dominance. A major site of this struggle is the apoplast. In -soybean interactions, PsXEG1, a pathogen-secreted apoplastic endoglucanase, is a key focal point of this struggle, and the subject of two layers of host defense and pathogen counterdefense.

Survey of nil per os duration of patients admitted to the emergency department due to vomiting.

During the acute phase of vomiting, even a small amount of water may not be tolerated by mouth. Early refeeding may cause re-vomiting in patients, whereas late refeeding may result in dehydration and hypoglycemia. Nil per os (NPO) may be generally recommended by primary physicians, but the appropriate NPO duration for these patients is still unclear.

A effector recruits a host cytoplasmic transacetylase into nuclear speckles to enhance plant susceptibility.

Oomycete pathogens secrete host cell-entering effector proteins to manipulate host immunity during infection. We previously showed that PsAvh52, an early-induced RxLR effector secreted from the soybean root rot pathogen, , could suppress plant immunity. Here, we found that PsAvh52 is required for full virulence on soybean and binds to a novel soybean transacetylase, GmTAP1, in vivo and in vitro.

Leucine-rich repeat receptor-like gene screen reveals that Nicotiana RXEG1 regulates glycoside hydrolase 12 MAMP detection.

Activation of innate immunity by membrane-localized receptors is conserved across eukaryotes. Plant genomes contain hundreds of such receptor-like genes and those encoding proteins with an extracellular leucine-rich repeat (LRR) domain represent the largest family. Here, we develop a high-throughput approach to study LRR receptor-like genes on a genome-wide scale.

A paralogous decoy protects apoplastic effector PsXEG1 from a host inhibitor.

The extracellular space (apoplast) of plant tissue represents a critical battleground between plants and attacking microbes. Here we show that a pathogen-secreted apoplastic xyloglucan-specific endoglucanase, PsXEG1, is a focus of this struggle in the -soybean interaction. We show that soybean produces an apoplastic glucanase inhibitor protein, GmGIP1, that binds to PsXEG1 to block its contribution to virulence.

The Phytophthora sojae Avr1d gene encodes an RxLR-dEER effector with presence and absence polymorphisms among pathogen strains.

Soybean root and stem rot is caused by the oomycete pathogen Phytophthora sojae. The interaction between P. sojae and soybean fits the "gene-for-gene" hypothesis.
