A Review Of Plant–Microbe Interactions In The Rhizosphere And The Role Of Root Exudates In Microbiome Engineering, Anagha Wankhade, Emma Wilkinson, David W. Britt, Amita Kaundal

Biological Engineering Student Research

Microbial interactions within the rhizosphere are fundamental to plant health, influencing nutrient availability, stress tolerance, and pathogen resistance. Beneficial microbes, such as plant growth-promoting microbes (PGPMs), including bacteria and mycorrhizal fungi, enhance plant resilience through mechanisms like nutrient solubilization, phytohormone production, and pathogen suppression via antimicrobial compounds and siderophores. Root exudates, composed of sugars, organic acids, and secondary metabolites, act as chemoattractants that shape the rhizosphere microbiome by recruiting beneficial microbes. Microbial metabolites can, in turn, modulate plant physiology and exudate profiles, thereby reinforcing mutualistic interactions. Stress conditions alter exudate composition, enabling plants to attract specific microbes that aid in …

A critical step in cell morphogenesis is the extension of actin-dense pseudopods, controlled by actin-binding proteins (ABPs). While this process is well-understood on glass coverslips, it is less so in compliant three-dimensional environments. Here, we knocked out a series of ABPs in osteosarcoma cells and evaluated their effect on pseudopod extension on glass surfaces (2D) and in collagen gels (3D). Cells lacking the longest Arp3 gene variant, or with attenuated Arp2/3 activity, had the strongest reduction in pseudopod formation between 2D and 3D. This was largely due to reduced activity of the hybrid Arp2/3-vinculin complex, which was dispensable on glass. …
