AI Article Synopsis
- The study focuses on the phylogenetic relationships between two related genera within the Sapotaceae family, which includes economically important species like the miracle berry.
- The research utilizes nuclear and chloroplast DNA data, applying Bayesian analyses and Maximum likelihood methods to build phylogenetic trees that reveal six clades.
- Findings indicate that the two genera are closely related and question the validity of their current classification, as one genus appears to be polyphyletic, highlighting the need for a reevaluation of all species in these genera.
Article Abstract
and are two closely related genera of the sub-family Chrysophylloideae in the family Sapotaceae. It has been reported that the two genera are a monophyletic group, and their generic limitations are uncertain. is an economically important genus that includes the medicinally and culinarily important plant, -miracle berry, . The phylogenetic relationships among the species are poorly understood. This study has been conducted to refine the phylogenetic relationships between and within the two genera utilizing nuclear and chloroplast DNA data. Bayesian analyses and Maximum likelihood of nuclear internal transcribed spacer () and plastid () sequences were used to reconstruct the phylogeny of the two genera. Phylogenetic trees generated for both regions (nuclear and plastid) resulted in the resolution of six clades. Four of the clades correspond to species in the genus and two clades include species of . The two clades of are nested within suggesting that the two genera are closely related and may not merit their current circumscription as distinct genera. Also, is confirmed to constitute more than one lineage suggesting it is not monophyletic in its current definition. Overall, the study suggests the need for a comprehensive evaluation of all species currently recognized in the two genera.

The Hepatincolaceae (Alphaproteobacteria) are a group of bacteria that inhabit the gut of arthropods and other ecdysozoans, associating extracellularly with microvilli. Previous phylogenetic studies, primarily single-gene analyses, suggested their relationship to the Holosporales, which includes intracellular bacteria in protist hosts. However, the genomics of Hepatincolaceae is still in its early stages.

The Canadian province of Alberta contains substantial oilsands reservoirs, consisting of bitumen, clay and sand. Extracting oil involves separating bitumen from inorganic particles using hot water and chemical diluents, resulting in liquid tailings waste with ecotoxicologically significant compounds. Ongoing efforts aim to reclaim tailings-affected areas, with protist colonisation serving as one assessment method of reclamation progress.

SKP1 constitutes the Skp1-Cullin-F-box ubiquitin E3 ligase (SCF), which plays a role in plant growth and development and biotic and abiotic stress in ubiquitination. However, the response of the gene family to abiotic and biotic stresses in cotton has not been well characterized. In this study, a total of 72 genes with the conserved domain of SKP1 were identified in four Gossypium species.

The Really Interesting New Gene (RING) E3 ubiquitin ligases represent the largest class of E3 ubiquitin ligases involved in protein degradation and play a pivotal role in plant growth, development, and environmental responses. Despite extensive studies in numerous plant species, the functions of RING E3 ligases in cotton remain largely unknown. In this study, we performed systematic identification, characterization, and expression analysis of genes in cotton.
