Inhibiting pathogen chemotaxis is a promising strategy for reducing disease pressure. However, this strategy is currently in the proof-of-concept stage. Here, was used as a model, as its biflagellated zoospores could sense genistein, a soybean root exudate, to navigate host and initiate infection.

In flowering plants, pollen grain must undergo a series of critical processes, including adhesion, hydration, and germination, which are dependent on the stigma, to develop a pollen tube. This pollen tube then penetrates the stigma to reach the internal tissues of pistil, facilitating the transport of non-motile sperm cells to the embryo sac for fertilization. However, the dry stigma, characterized by the absence of an exudate that typically envelops the wet stigma, functions as a multi-layered filter in adhesion, hydration, germination and penetration that permits the acceptance of compatible pollen or tubes while rejecting incompatible ones, thereby protecting the embryo sac from ineffective fertilization and maintaining species specificity.

In multiple neurodegenerative diseases, including age-related macular degeneration, retinitis pigmentosa, and macular telangiectasia type 2 (MacTel), retinal pigment epithelial (RPE)-cells proliferate and migrate into the neuroretina, forming intraretinal pigment plaques. Though these pigmentary changes are hallmarks of disease progression, it is unknown if their presence is protective or detrimental.Here, we first evaluated the impact of pigment plaques on vascular changes and disease progression in MacTel.

The rhizosphere is a key interface between plants, microbes and the soil which influences plant health and nutrition and modulates terrestrial biogeochemical cycling. Recent research has shown that the rhizosphere environment is far more dynamic than previously recognised, with evidence emerging for diurnal rhythmicity in rhizosphere chemistry and microbial community composition. This rhythmicity is in part linked to the host plant's circadian rhythm, although some heterotrophic rhizosphere bacteria and fungi may also possess intrinsic rhythmicity.

Wetlands are hotspots for carbon and nutrient cycling. The important role of plant-microbe interactions in driving wetland biogeochemistry is widely acknowledged, prompting research into their molecular biological basis for a deeper understanding of these processes. We analyzed transcriptomic responses of soil microbes to root exudates in coastal wetland soils using CO pulse labeling.
