This study shows that HAR1 in Lotus japonicus enhances growth and nitrogen use under high nitrate conditions through organic acid metabolism, independent of symbiotic relationships.

The paper identifies chromid-like secondary replicons in Ktedonobacteria as key genomic regions harboring biosynthetic gene clusters, expanding understanding of soil microbial secondary metabolism.

The paper reports the discovery of non-tandemly repeated rDNAs and their intragenomic heterogeneity in Rhizophagus irregularis, suggesting a link to adaptation and environmental response.
