“…The flow cytometry measurements of 24 Lathyrus plant species showed that the 2C DNA content varied more than two-fold within the genus, ranging from 10.2 pg to 24.2 pg [36]. Certain species can promote evolution through chromosome structural rearrangement and polyploidization, as seen in the presence of 2, 4, 8, and 10 ploidy levels in the Calliandra genus [37]. The genome size of Gleditsia was determined using maize B73 as an internal standard; it ranged from 686.08 M to 1034.24 M (Figure 1).…”

The Gleditsia genus has various uses, including those for medicinal, edible, chemical, timber, and ornamental purposes, and the genus is widely distributed in China. However, there is still a lack of understanding about the phenotypic and growth differences seen among species within the Gleditsia genus. In this study, we compared and analyzed the various species of Gleditsia seedlings in terms of their genotypes, chromosome numbers, physiological growth, photosynthesis, hormone content, and gene expression. The results showed that the genome size of the Gleditsia genus ranges from 686.08 M to 1034.24 M and that all Gleditsia species are diploid. Among the species studied, G. fera can be divided into fast-growing genotype, exhibited several advantages in terms of leaf type and photosynthetic capacity, high levels of GA3, and fast stem growth, making it a species with the potential for promotion and application. G. delavayi exhibited high levels of auxin and cytokinin and strong photosynthetic capacity, with rapid growth in terms of plant height. G. microphylla had the lowest levels of IAA, IBA, and NAA in the apical, and showed slow growth in terms of plant height. Weighted correlation network analysis (WGCNA) identified the hub genes associated with traits. This study lays a material and theoretical foundation for the development of new resources for Gleditsia breeding and rootstock selection and provides a basis for the mechanism of rootstock–scion interaction.

“…A citogenética é considerada uma ferramenta fundamental na caracterização dos recursos genéticos vegetais (MARTINS et al, 2021;ALMEIDA et al, 2022) e tem grande importância nos estudos onde se avalia as relações evolutivas entre as espécies (PAULA et al, 2020;IBIAPINO et al, 2022a;2022b;COSTA et al, 2023). As abordagens citogenéticas envolvendo o número, morfologia, tamanho dos cromossomos, bem como presença de constrição secundária e quantidade de heterocromatina no cariótipo são dados importantes para a compreensão do processo de evolução nas plantas (RITO et al, 2021;GUERRA, 2000;MATA-SUCRE et al, 2020;CORDEIRO et al, 2022) As lâminas foram feitas de acordo com o protocolo de Carvalho & Saraiva (1993), com algumas modificações.…”

Phylogenetic relationships for the genusCalliandrasectionAndrocallis(Fabaceae) were reconstructed, including previously sequenced species from Central and South America and unexamined species from Colombia, one ofCalliandramain diversity centers. Here, we generated novel DNA sequences ofCalliandraspecies from Colombia for the nuclear Internal Transcribed Spacer (ITS)and the chloroplasttrnLandtrnL-Fintergenic spacer. By incorporating a broader taxonomic sampling, the relationships among main clades inAndrocalliswere clarified, providing a systematics framework in which to test evolutionary hypotheses. Phylogenetic analysis recovered five well-supported clades withinAndrocallis. Most species within each clade had similar geographical distributions and relationships between the five major clades are strongly supported for the first time. However, coreAndrocallisrelationships, including most species from Colombia sequenced here, remain unclear. A second goal of this study was to determine the taxonomic status ofCalliandra medellinensis. This enigmatic taxon emblematic of Medellín, Colombia, is found in limited numbers within the Aburrá Valley and has been proposed to be a hybrid taxon. Here,C. medellinensis,C. magdalenaeandC. haematocephalawere not monophyletic within the coreAndrocallisclade. This suggests thatC. medellinensiscould potentially be an interspecific hybrid betweenC. magdalenaeandC. haematocephala, thus challenging the taxonomic status of this species; however, more informative molecular markers should be used in future studies. Specifically, genomic studies should assess interspecific hybridization demographic models. Such insights can illuminate theC. medellinensisorigin, guiding conservation strategies and providing valuable evolutionary overviews.
