Soft rot is a destructive disease that inflicts significant losses on agricultural production and the economy post-harvest. Biocontrol strategies based on antagonistic microorganisms have a broad application prospect to fight against plant pathogens. This study utilized fluorescence-activated droplet sorting （FADS） technology as an alternative to traditional plate culture methods to isolate microorganisms with antagonistic activity against the soft rot pathogen Erwinia carotovora Ecc15. Initially， the culture performance of the FADS platform was evaluated by analyzing bacterial diversity in droplet culture samples and agar plate culture samples， our data showed that droplet culture exhibited higher species richness and diversity than plate culture， and more than 95% of the OTUs in the droplet samples belonged to the rare biosphere. Additionally， we developed a GFP-Ecc15-based FADS screening system， which achieved an enrichment ratio of up to 148. Using this system， we successfully screened 32.antagonistic bacteria from rhizosphere soil sample of healthy konjac plants， and some may be novel microbial resources， including the genera Lelliottia， Buttiauxella and Leclercia. Notably， strain D-62.exhibited the strongest antibacterial ability against Ecc15， with an inhibition zone diameter of （2..86 ± 1.56） mm. In vivo experiments conducted on the corms of Amorphophallus konjac demonstrated that strain D-62.could effectively reduce the infection ability of Ecc15 to the corms， indicating that strain D-62.has the potential to be developed as a biocontrol agent. Our findings suggested that the FADS screening system showed a screening efficiency approximately 3 × 103times higher than plate screening system， while significantly reducing costs of infrastructure， labor and consumables， it provides theoretical guidance for the screening of other plant pathogen biocontrol bacteria.

Global efforts to address malnutrition and hidden hunger, particularly prevalent in low- and middle-income countries, have intensified, with a focus on enhancing the nutritional content of staple crops like rice. Despite serving as a staple for over half of the world's population, rice falls short in meeting daily nutritional requirements, especially for iron(Fe) and zinc(Zn). Genetic resources, such as wild rice species and specific rice varieties, offer promising avenues for enhancing Fe and Zn content. Additionally, molecular breeding approaches have identified key genes and loci associated with Fe and Zn accumulation in rice grains. This review explores the genetic resources and molecular mechanisms underlying Fe and Zn accumulation in rice grains. The functional genomics involved in Fe uptake, transport, and distribution in rice plants have revealed key genes such as OsFRO1, OsIRT1, and OsNAS3. Similarly, genes associated with Zn uptake and translocation, including OsZIP11 and OsNRAMP1, have been identified. Transgenic approaches, leveraging transporter gene families and genome editing technologies, offer promising avenues for enhancing Fe and Zn content in rice grains. Moreover, strategies for reducing phytic acid(PA) content, a known inhibitor of mineral bioavailability, have been explored, including the identification of low-PA mutants and natural variants. The integration of genomic information, including whole-genome resequencing and pan-genome analyses, provides valuable insights into the genetic basis of micronutrient traits and facilitates targeted breeding efforts. Functional genomics studies have elucidated the molecular mechanisms underlying Fe uptake and translocation in rice. Furthermore, transgenic and genome editing techniques have shown promise in enhancing Fe and Zn content in rice grains through the manipulation of key transporter genes. Overall, the integration of multi-omics approaches holds significant promise for addressing global malnutri
