Selfing Shapes Fixation of a Mutant Allele Under Flux Equilibrium.

Sexual reproduction with alternative generations in a life cycle is an important feature in eukaryotic evolution. Partial selfing can regulate the efficacy of purging deleterious alleles in the gametophyte phase and the masking effect in heterozygotes in the sporophyte phase. Here, we develop a new theory to analyze how selfing shapes fixation of a mutant allele that is expressed in the gametophyte or the sporophyte phase only or in two phases.

Population Structure and Genetic Diversity of the (Meliaceae) Complex Assayed with Chloroplast DNA Markers.

is a deciduous or semi-deciduous tree species and belongs to the genus of the Meliaceae family. Owing to low natural regeneration and over-exploitation, the species is listed as an endangered species at level II in China and its conservation has received increasing concern. Here, we sampled 447 individuals from 29 populations across the range-wide distribution of the complex in China and assessed their genetic variation using two chloroplast DNA markers.

A Community-Based Framework Integrates Interspecific Interactions into Forest Genetic Conservation.

Forest genetic conservation is typically species-specific and does not integrate interspecific interaction and community structure. It mainly focuses on the theories of population and quantitative genetics. This approach depicts the intraspecific patterns of population genetic structure derived from genetic markers and the genetic differentiation of adaptive quantitative traits in provenance trials.

Assessing the phylogenetic relationship among varieties of (Meliaceae) in sympatry with chloroplast genomes.

is an endangered species due to over-cutting and low natural regeneration in China. Its genetic conservation is of an increasing concern. However, several varieties are recognized according to the leaf and flower traits, which complicates genetic conservation of .

Population Structure and Genetic Diversity in the Natural Distribution of in China.

(Roxb.) Bosser is a fast-growing deciduous tree species and belongs to the genus of the Rubiaceae family. This species has great economic and medical values in addition to being an important timber species for multiple industrial purposes.

Phylogeography of (Meliaceae) Complex in China Inferred from Cytonuclear Markers.

is an important timber species but is recognized as an endangered species at level II in China. Its genetic conservation is of increasing concern. Provenance trials and other breeding programs were conducted to develop seed transfer rules and multiplications.

One-Pot Facile Encapsulation of Dimethyloxallyl Glycine by Nanoscale Zeolitic Imidazolate Frameworks-8 for Enhancing Vascularized Bone Regeneration.

In the process of bone tissue regeneration, regulation of osteogenesis-angiogenesis coupling is of great importance. Therefore, dimethyloxallyl glycine (DMOG) is loaded by nanoscale zeolitic imidazolate frameworks-8 (ZIF-8) to obtain a drug-loading system that can promote osteogenesis-angiogenesis coupling. Characterization of the drug-loading nanoparticles (DMOG@ZIF-8) reveals that DMOG is successfully loaded into ZIF-8 by two different methods, and the DMOG@ZIF-8 is prepared using the one-pot method (OD@ZIF-8) achieves higher loading efficiency and longer release time than those prepared using the post-loading method (PD@ZIF-8).

Evolutionary Divergence between and Assayed with Their Whole Genome Sequences.

and belong to the genus of the Meliaceae family and are important timber species in China. is an endangered species at level II due to overcutting and a low rate of natural regeneration. was cultivated as an economic and nutritious tree for more than 2000 years.

A Chromosome-Level Genome Assembly of Toona ciliata (Meliaceae).

Toona ciliata Roem is an important timber species in the Toona genus of the Meliaceae family and an endangered species due to over-cutting and a low rate of natural regeneration in China. Although molecular markers have been applied to studying population genetic diversity, the absence of a reliable reference genome limits in-depth genetic conservation and evolutionary studies of this species. Here, we reported a high-quality assembly of the whole genome sequence of T.
