Genetic diversity, mating system and reproductive phenology of Mimosa scabrella Benth: Implications for seed collection

Both populations of Mimosa scabrella are confirmed as valuable seed sources for restoration, with specific recommendations to maximize genetic representativeness and adaptive potential.

Effects of crossing distance on components of fitness in two rare rock plants.

To alleviate negative effects of genetic drift on rare plants, it has been suggested to artificially increase gene flow between isolated populations and create new populations by mixing different provenances to maximize genetic variation. However, there is also a risk of outbreeding depression. We studied the effects o...

Intra-population genetic diversity modeling of date palm (Phoenix dactylifera L.) population in Niger

Genetic variability can provide important information on how populations behave internally and can also serve as a valuable guide for conservation. In the case of cultivated plants, the conservation of genetic variability contributes significantly to the stabilization of agricultural production. Then, this study aims t...

Genetic Diversity of the 4th-Cycle Breeding Population of Cunninghamia lanceolata (Lamb.) Hook. Using SSR Markers

: Cunninghamia lanceolata (Lamb.) Hook., a fast-growing timber species endemic to China, has been constrained in genetic improvement and marker-assisted breeding programs by the paucity of molecular-level genetic diversity information. In this study, 22 pairs of highly polymorphic SSR molecular markers were designed an...

Population Genomics of Chinese Melia azedarach Germplasm: Latitudinal Genetic Structure, Spatial–Climatic Associations, and Climate-Associated Candidate Genes

To understand how geography shapes the genetic variation of Melia azedarach, we sequenced the whole genomes of 91 accessions from 91 maternal half-sib families across 15 provenances maintained in the National Germplasm Bank of China, an ex situ collection representing conserved germplasm. Genetic diversity increased fr...

Panmixia in a Widespread Butterfly: High Dispersal and Ecological Generalism Buffer Against Landscape Fragmentation

ABSTRACT Habitat fragmentation is widely expected to reduce population connectivity and increase genetic differentiation, although the strength of these effects depends on species‐specific traits such as dispersal ability. Here, we investigated the population genetic structure of the cosmopolitan butterfly, Pieris rapa...
