Hybridization potential and genetic influence of parental varieties on fruit size and set rate in Gleditsia sinensis

open access: yesScientific Reports
Gleditsia sinensis is a dioecious perennial tree, with its fruit size directly impacting its economic value. Investigating the feasibility of hybridization between different Gleditsia varieties and the influence of parentage on fruit size is crucial.

Genetic structure and evolution of the Leishmania genus in Africa and Eurasia: what does MLSA tell us [PDF]

open access: yes, 2013
Leishmaniasis is a complex parasitic disease from a taxonomic, clinical and epidemiological point of view. The role of genetic exchanges has been questioned for over twenty years and their recent experimental demonstration along with the identification ...

Phylogenomics and Biogeography of the Eastern Asian–Eastern North American Disjunct Genus Hylodesmum (Fabaceae)

open access: yesBiological Diversity, EarlyView.
Integrating data from plastid genomes, nrDNA, and 353 low‐copy nuclear genes, this study establishes a robust phylogenetic framework for Hylodesmum. This framework supports a taxonomic revision recognizing 18 species and reveals a complex pattern of bidirectional EA–ENA dispersal, with mammals as a plausible dispersal agent. ABSTRACT Phylogenomics with

Effects of outbreeding depression on meristics and bilateral asymmetry in hybrids of spatially separated populations of pink salmon (Oncorhynchus gorbuscha) [PDF]

open access: yes, 2005
Thesis (M.S.) University of Alaska Fairbanks, 2005Different populations of a species distributed over diverse conditions adapt to their local environments to improve their ability to survive or reproduce. Intraspecific hybridization can alter the locally

Unsuccessful Cassava Brown Streak Disease (CBSD) evaluation attempts in western Democratic Republic of Congo and implications with cassava root necrosis disease (CRND) etiology [PDF]

open access: yes, 2020
Open Access ArticleCassava brown streak disease (CBSD) is the second most important virus disease after Cassava mosaic disease (CMD), infecting cassava (ManihotesculetaCrantz) in Africa. The disease is caused by two distinct viruses, Cassava brown streak

The spread of non‐native species

open access: yesBiological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

INTERSPECIFIC HYBRIDIZATION IN BEGONIA [PDF]

open access: yesHortScience, 1992
An interspecific hybridization program involving ancestral species of the Begonia Semperflorens Cultorum Group was initiated to expand the genetic base of this group. Viable seeds were recovered from four reciprocal crosses. F, progenies were sterile and phenotypically intermediate between parental types.

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Backcrosses in interspecific hybridization in sunflower [PDF]

open access: yes, 2003
When incorporating desirable traits (resistance to causal agents of various diseases) from the wild relatives into the cultivated sunflower, some undesirable ones are introduced too (branching, small head diameter, low oil content, etc). To overcome this

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
