Plant Immunity Modulation in Arbuscular Mycorrhizal Symbiosis and Its Impact on Pathogens and Pests.
Annu Rev Phytopathol
September 2024
Arbuscular mycorrhizal (AM) symbiosis is the oldest and most widespread mutualistic association on Earth and involves plants and soil fungi belonging to Glomeromycotina. A complex molecular, cellular, and genetic developmental program enables partner recognition, fungal accommodation in plant tissues, and activation of symbiotic functions such as transfer of phosphorus in exchange for carbohydrates and lipids. AM fungi, as ancient obligate biotrophs, have evolved strategies to circumvent plant defense responses to guarantee an intimate and long-lasting mutualism.

Beneficial microbes induce resistance in plants (MIR), imposing both lethal and sublethal effects on herbivorous insects. We argue that herbivores surviving MIR carry metabolic and immunological imprints of MIR with cascading effects across food webs. We propose that incorporating such cascading effects will strongly enhance the current MIR research framework.

- - The study redefined fatigue in clinical populations by considering dimensions like perceived fatigue and fatigability, focusing on individuals with Spinal Cord Injury (SCI) and Multiple Sclerosis (MS) versus able-bodied controls.
- - A total of 67 participants (23 with SCI, 23 with MS, 21 able-bodied) were assessed through two walking tests and the Fatigue Severity Scale (FSS) to measure differences in trait and state fatigue.
- - Findings showed that individuals with MS experience the highest levels of trait fatigue, and although walking tasks induced similar state fatigue between groups, patients had longer-lasting fatigue effects compared to able-bodied individuals.
Article Synopsis
- Beneficial root microbes enhance plant growth and crop yield while providing protection against pests by activating plant defense mechanisms.
- The study tested how these microbes influence indirect resistance to herbivores by examining tomato plants inoculated with specific fungi in relation to insect predation.
- Results showed that while the microbes slightly affected volatile emissions after herbivory, they significantly influenced gene expression related to plant defense, highlighting their potential role in integrated pest management strategies.
Persons with disabilities have historically been subjected to discrimination and exclusion, placing them in dangerous situations of social vulnerability. The Convention on the Rights of Persons with Disabilities, passed on the 13th of December 2006, was an important legislative landmark for valuing the rights of this population group. This study involved a bibliometric analysis of 1024 research articles published in Scopus on the social, workplace, educational, and financial inclusion of persons with disabilities since the Convention.
