Caesalpinioideae is the second largest subfamily of legumes (Leguminosae) with ca. 4680 species and 163 genera. It an ecologically economically important group formed mostly woody perennials that range from large canopy emergent trees to functionally herbaceous geoxyles, lianas shrubs, which has a global distribution, occurring on every continent except Antarctica. Following recent re-circumscription 15 genera as presented in Advances Legume Systematics 14, Part 1, using basis phylogenomic analysis 997 nuclear gene sequences for 420 all but five currently recognised subfamily, we present new higher-level classification subfamily. The comprises eleven tribes, are either new, reinstated or re-circumscribed at this rank: Caesalpinieae Rchb. (27 / 223 species), Campsiandreae LPWG (2 5–22), Cassieae Bronn (7 695), Ceratonieae (4 6), Dimorphandreae Benth. 35), Erythrophleeae /13), Gleditsieae Nakai (3 20), Mimoseae (100 3510), Pterogyneae (1 1), Schizolobieae (8 42–43), Sclerolobieae & Hook. f. (5 113). Although many these lineages have been named past, tribes informal generic groups, their circumscriptions varied widely changed over past decades, such described here differ membership those previously recognised. Importantly, approximately 3500 100 former Mimosoideae now placed reinstated, newly circumscribed, tribe Mimoseae. Because size ecological importance tribe, also provide clade-based system includes 17 lower-level clades. Fourteen remain unplaced clades: eight resolved two grades six phylogenetically isolated monogeneric lineages. In addition classification, key genera, morphological descriptions notes diversity growth forms, foliage, flowers fruits illustrated each genus distribution map, based quality-controlled herbarium specimen localities. A glossary specialised terms used legume morphology provided. This provides solid communication framework downstream analyses biogeography, trait evolution diversification, well taxonomic revision still understudied

Abstract Legumes establish symbiosis with rhizobia by forming a symbiotic interface that enables cross‐kingdom exchanges of signaling molecules and nutrients. However, how host organelles interact symbiosomes at the remains elusive during endosymbiosis. Here, cells are reconstructed using 3D scanning electron microscopy (SEM) uncover endoplasmic reticulum (ER) undergoes dynamic expansion to gradually enwrap symbiosomes, facilitating their compartmentalization Consistently, altering ER lamellar overexpressing MtRTNLBs , reticulons responsible for tubulation, impairs accommodation symbiosome development. Intriguingly, unfolded protein response (UPR)‐marker genes, bZIP60 IRE1A/B show continuously activated expression nodule development, two UPR‐deficient mutants, ire1b bzip60 exhibit compromised biogenesis defective Collectively, findings underpin UPR activation as key events in reveal an intrinsic coupling morphology proper root symbiosis.

Legumes establish mutualistic interactions with pollinators and nitrogen (N)-fixing bacteria that are critical for plant reproduction ecosystem functioning. However, we know little about how N-fixing soil nutrient availability affect attractiveness to pollinators.
