Interspecific Crosses Yield Sterile Triploid Porterweed: A Sustainable Alternative to Invasive Nettleleaf Porterweed

HortScience
Porterweed plants (Stachytarpheta sp.), notably the nettleleaf porterweed (Stachytarpheta cayennensis), present both ecological benefits and challenges.

Evidence of Chromosomal Instability in Prostate Cancer Determined by Spectral Karyotyping (SKY) and Interphase FISH Analysis

Neoplasia: An International Journal for Oncology Research, 2001
The way in which cytogenetic aberrations develop in prostate cancer (Cap) is poorly understood. Spectral karyotype (SKY) analysis of Cap cell lines has shown that they have unstable karyotypes and also have features associated with chromosomal ...

The Effect of Assisted Reproductive Technologies on Human Sex Ratios

Australian and New Zealand Journal of Obstetrics and Gynaecology, EarlyView.
ABSTRACT Background Modern assisted reproductive technology (ART), including pre‐implantation genetic testing for aneuploidy (PGT‐A), has opened new avenues in understanding early embryonic events and has simultaneously raised questions about the impact of ART itself on sex ratios.

When sexual meets apomict: genome size, ploidy level and reproductive mode variation of Sorbus aria s.l. and S. austriaca (Rosaceae) in Bosnia and Herzegovina.

Annals of Botany, 2015
BACKGROUND AND AIMS Allopolyploidy and intraspecific heteroploid crosses are associated, in certain groups, with changes in the mating system. The genus Sorbus represents an appropriate model to study the relationships between ploidy and reproductive ...

TRAPPC2l Participates in Male Germ Cell Development by Regulating Cell Division

Cell Proliferation, EarlyView.
Trappc2l is crucial for maintaining the quiescent state of male gonocytes. In the absence of Trappc2l, the quiescent state of gonocytes is disrupted, leading to premature and abnormal initiation of meiosis, which consequently results in subsequent abnormalities in sperm development. ABSTRACT TRAPPC2L is a core subunit of the Transport Protein Particle (

Are tetraploids more successful? Floral signals, reproductive success and floral isolation in mixed-ploidy populations of a terrestrial orchid.

Annals of Botany, 2015
BACKGROUND AND AIMS Polyploidization, the doubling of chromosome sets, is common in angiosperms and has a range of evolutionary consequences. Newly formed polyploid lineages are reproductively isolated from their diploid progenitors due to triploid ...

Climate‐Mediated Hybridisation and the Future of Andean Forests

Journal of Biogeography, EarlyView.
ABSTRACT The tropical Andes face unprecedented warming and shifting precipitation patterns due to climate change and land‐use alteration, challenging the future of Andean forests. During the Quaternary, many Andean trees responded to climate change through upslope migrations but, while there is evidence of such ongoing migrations in many species, they ...

Reproductive biology of invasive grass carp (Ctenopharyngodon idella) in two North American systems

Journal of Fish Biology, EarlyView.
Abstract Grass carp (Ctenopharyngodon idella) are nonnative, herbivorous freshwater fish that represent an ecological threat in North American waters. However, data are limited on reproductive biology specific to wild populations in midwestern North America, despite recent concern for grass carp establishment within the Great Lakes.
