Comparative proteomic analysis identifies proteins associated with arbuscular mycorrhizal symbiosis in .

Citrus, one of the most widely cultivated fruit crops in the world, relies on arbuscular mycorrhizal fungi (AMF) to absorb nutrients and water from soil. However, the molecular mechanism of AM symbiosis (AMS) in citrus in general have largely been understudied. Here, using a TMT labeling proteomic approach, we identified 365 differentially expressed proteins (DEPs) in roots of (a common citrus rootstock) upon colonization as compared with uninoculated roots, of which 287 were up-regulated and 78 were down-regulated.

Plant lysin motif extracellular proteins are required for arbuscular mycorrhizal symbiosis.

Arbuscular mycorrhizal fungi (AMF) can form a mutually beneficial symbiotic relationship with most land plants. They are known to secrete lysin motif (LysM) effectors into host root cells for successful colonization. Intriguingly, plants secrete similar types of LysM proteins; however, their role in plant-microbe interactions is unknown.

Integrated miRNA-mRNA analysis reveals candidate miRNA family regulating arbuscular mycorrhizal symbiosis of Poncirus trifoliata.

Over 70% land plants live in mutualistic symbiosis with arbuscular mycorrhizal (AM) fungi, and maintenance of symbiosis requires transcriptional and post-transcriptional regulation. The former has been widely studied, whereas the latter mediated by symbiotic microRNAs (miRNAs) remains obscure, especially in woody plants. Here, we performed high-throughput sequencing of the perennial woody citrus plant Poncirus trifoliata and identified 3750 differentially expressed genes (DEGs) and 42 miRNAs (DEmiRs) upon AM fungal colonization.

Cytological Observation of the Infectious Process of on Peach Leaves.

Peach scab caused by is one of the most destructive fungal diseases of peach worldwide, and it seriously affects peach production. Until now,the infectious process and pathogenesis of on peach have remained unclear. Here we present the infection behavior of at the ultrastructural and cytological levels in peach leaves with combined microscopic investigations (i.

A Medicago truncatula SWEET transporter implicated in arbuscule maintenance during arbuscular mycorrhizal symbiosis.

Plants form a mutualistic symbiosis with arbuscular mycorrhizal (AM) fungi, which facilitates the acquisition of scarce minerals from the soil. In return, the host plants provide sugars and lipids to its fungal partner. However, the mechanism by which the AM fungi obtain sugars from the plant has remained elusive.

Comparative transcriptome analysis of Poncirus trifoliata identifies a core set of genes involved in arbuscular mycorrhizal symbiosis.

The perennial woody plants of citrus are one of the most important fruit crops in the world and largely depends on arbuscular mycorrhizal symbiosis (AMS) to obtain essential nutrients from soil. However, the molecular aspects of AMS in citrus and perennial woody plants in general have largely been understudied. We used RNA-sequencing to identify differentially expressed genes in roots of Poncirus trifoliata upon mycorrhization by the AM fungus Glomus versiforme and evaluated their conservation by comparative transcriptome analyses with four herbaceous model plants.
