PSKR1 balances the plant growth–defence trade-off in the rhizosphere microbiome

Plants are colonized by numerous beneficial microorganisms in the rhizosphere, including Pseudomonas fluorescens, that provide benefits including nutrient acquisition and pathogen protection. Host plants must tune their immune systems to restrict microbial overgrowth, while avoiding overstimulation of…

Volatile methyl jasmonate from roots triggers host-beneficial soil microbiome biofilms

Volatile molecules released from plant roots (root VOCs, rVOCs) can diffuse over long distances, thereby increasing the sphere of plant influence. However, their influence on complex soil microbial communities (or microbiomes) and ecological implications are poorly understood, mainly due to technical…

Review: The exocyst complex is targeted by pathogen effectors

The exocyst complex is a conserved octameric protein complex in eukaryotic cells. Its primary function is to tether secretory vesicles to the plasma membrane during the exocytosis process, and it is also involved in autophagy and host-pathogen interactions. Intriguingly, EXO70, one of the subunits of…

Review: CLAVATA signaling in plant-environment interactions

CLAVATA 3/EMBRYO SURROUNDING REGION-related (CLE) peptides and CLAVATA type receptors have been well charecterized for their role in root and shoot apical meristem maintenance in Arabidopsis. CLE peptides are also referred to as “peptide hormones” for their role in contolling physiological and developmental…

Ferns unleashed: Novel insecticidal proteins IPD113 challenge Bt resistance

Insect pests pose a significant threat to global crop production, with lepidopteran species like corn earworm and armyworms causing substantial losses. The widespread use of insecticidal proteins from Bacillus thuringiensis (Bt) in crops has been a key strategy to combat these pests. However, the emergence…

Review: Till death do us pair: Co-evolution of plant–necrotroph interactions

This interesting and well-written review by Derbyshire and Raffaele takes a step back from the molecular interactions between plant and pathogen and discusses them in light of co-evolutionary processes. The review starts with a useful introduction and definition of concepts about “robustness” in…

Review: Challenges to improving plant growth through introduced microbes

Plants are closely associated with large numbers of microbes that live in, on, and around them; these are collectively called the plant microbiota. Microbes can be pathogenic, neutral, or beneficial. Beneficial microbes might enhance nutrient uptake by the plant or suppress pathogenic microbes. There…

Listening to the whispers in the air: Plant eavesdropping in action

Plants release a variety of volatile organic compounds (VOCs), including green leaf volatiles (GLVs), terpenoids, and amino acid derivatives, in response to herbivore damage and injury. Healthy neighboring plants detect these VOCs as warning signals, prompting them to activate defense mechanisms. This…

Many modes of Striga resistance in sorghum

Witchweeds (Striga spp.) are parasitic plants. Like other weeds, they compete with food crops, but they do so very efficiently by penetrating host tissues and forming vascular connections. Through this effective extraction of nutrients and photosynthate from their hosts, Striga can literally wipe out…
