Alternative splicing regulation in plants by SP7-like effectors from symbiotic arbuscular mycorrhizal fungi.

Most plants in natural ecosystems associate with arbuscular mycorrhizal (AM) fungi to survive soil nutrient limitations. To engage in symbiosis, AM fungi secrete effector molecules that, similar to pathogenic effectors, reprogram plant cells. Here we show that the Glomeromycotina-specific SP7 effector family impacts on the alternative splicing program of their hosts.

Assessing Adherence to Adjuvant Hormone Therapy in Breast Cancer Patients in Routine Clinical Practice.

Background: Adjuvant hormone therapy (HT) in patients with hormone receptor-positive breast cancer (BC) increases overall survival (OS). A lack of adherence to adjuvant endocrine therapy is common, 31.0-73.

Exploring the synergistic effects of biochar and arbuscular mycorrhizal fungi on phosphorus acquisition in tomato plants by using gene expression analyses.

Arbuscular mycorrhizal (AM) fungi are symbiotic organisms that contribute significantly to plant mineral nutrition, mainly phosphate. However, their benefits are constricted by the availability of phosphate in the soil, and thus they are recalcitrant as amendment in highly fertilized soils. Biochars are by-products of the pyrolysis of biomass in the absence of oxygen.

Distinguishing friends from foes: Can smRNAs modulate plant interactions with beneficial and pathogenic organisms?

In their agro-ecological habitats, plants are constantly challenged by fungal interactions that might be pathogenic or beneficial in nature, and thus, plants need to exhibit appropriate responses to discriminate between them. Such interactions involve sophisticated molecular mechanism of signal exchange, signal transduction and regulation of gene expression. Small RNAs (smRNAs), including the microRNAs (miRNAs), form an essential layer of regulation in plant developmental processes as well as in plant adaptation to environmental stresses, being key for the outcome during plant-microbial interactions.

Overexpression of the Potato Monosaccharide Transporter Promotes Root Colonization by Symbiotic and Pathogenic Fungi by Increasing Root Sink Strength.

Root colonization by filamentous fungi modifies sugar partitioning in plants by increasing the sink strength. As a result, a transcriptional reprogramming of sugar transporters takes place. Here we have further advanced in the characterization of the potato SWEET sugar transporters and their regulation in response to the colonization by symbiotic and pathogenic fungi.
