Focus Issue Guest Editors: Tarek Hewezi, Hari Krishnan, Kevin Garcia, and Mina Ohtsu Submission Deadline: September 1, 2025 The rhizosphere is a dynamic environment for microbial activity, where plants engage in a wide array of interactions with surrounding microorganisms. These interactions can be mutually beneficial, as in the case of symbiotic partnerships that enhance nutrient acquisition and stress resilience, or detrimental, involving pathogens that compromise plant health and productivity. This focus issue aims to highlight cutting-edge advances in our understanding of the dynamic relationships between plants and microbes within the rhizosphere, encompassing both beneficial symbioses and pathogenic interactions. We encourage submissions that investigate both beneficial symbiotic associations, such as mycorrhizal and rhizobial interactions, and detrimental pathogenic processes caused by bacteria, fungi, oomycetes, and parasitic nematodes. Studies incorporating molecular, genetic, biochemical, ecological, and systems biology approaches are particularly welcome. We welcome original research articles, short communications, and reviews that explore molecular mechanisms, ecological significance, and potential agricultural applications. |

|  Sharing your work in MPMI, the IS-MPMI society journal, builds and strengthens our international community. Because MPMI is a gold open access journal, publishing in it means your work can be read by anyone with an Internet connection, anywhere, for free. Publishing in MPMI also contributes to the IS-MPMI mission of investing in early-career scientists and members of groups historically underrepresented in science. MPMI articles can be found by anyone using PubMed, Scopus, Web of Science, or Google Scholar. On average, authors submitting to MPMI receive a decision less than one month from the date of submission. What's New in MPMI Virtual Seminars offer authors of trending papers the opportunity to engage live with readers, and the IS-MPMI quarterly newsletter, Interactions, regularly publishes MPMI first-author interviews to provide visibility to early-career scientists from diverse backgrounds. The list of benefits goes on! Back in the day, we used to flip open our favorite journals and scan the table of contents for papers that interested us. Now, we use content alerts and social media to find what's new and exciting. I still scan the MPMI table of contents of every issue, however, and there is always something in which I'm interested. I hope you find your next paper in an MPMI table of contents soon! Adam Bogdanove

Phytophthora infestans RxLR Effector PITG06478 Hijacks 14-3-3 to Suppress PMA Activity Leading to Necrotrophic Cell Death Pathogens often induce cell death to successfully proliferate in the host plant. Plasma membrane H+-ATPases (PMAs) are targeted by either pathogens or plant immune receptors in immune response regulation. Although PMAs play pivotal roles in host cell death, the molecular mechanism of effector-mediated regulation of PMA activity has not been described. In this year's MPMI Best Student Paper Award-winning article, Ye-Eun Seo et al. report that the Phytophthora infestans RxLR effector PITG06478 can induce cell death in Nicotiana benthamiana, but the induced cell death is inhibited by fusicoccin (FC), an irreversible PMA activator.
Honorable Mentions
 Grapevine Fanleaf Virus RNA1-Encoded Proteins 1A and 1BHel Suppress RNA Silencing
Grapevine fanleaf virus (GFLV) (genus Nepovirus, family Secoviridae) causes fanleaf degeneration, one of the most damaging viral diseases of grapevines. Despite the substantial advances made in deciphering GFLV-host interactions, how this virus overcomes the host antiviral pathways of RNA silencing is still poorly understood. In this study, Jiyeong Choi et al. identified viral suppressors of RNA silencing (VSRs) encoded by GFLV, using fluorescence assays, and tested their capacity to modify host gene expression in transgenic Nicotiana benthamiana expressing the enhanced green fluorescent protein gene (EGFP).
 A Coculture of Enterobacter and Comamonas Species Reduces Cadmium Accumulation in Rice
The accumulation of cadmium (Cd) in plants is strongly impacted by soil microbes, but its mechanism remains poorly understood. In this study, Xing Wang et al. report the mechanism of reduced Cd accumulation in rice by coculture of Enterobacter and Comamonas species. In pot experiments, inoculation with the coculture decreased Cd content in rice grain, immobilized Cd in soils, and enhanced soil nutrients and enzyme activities. The coculture also colonized the rice rhizosphere, activated defense responses, and regulated Cd uptake and efflux in rice, suggesting it protects rice against Cd stress.
