Meiotic observation on ‘Bartzella’, an intersectional hybrid of Paeonia
Xibei zhiwu xuebao[Objective] Most intersectional hybrids in Paeonia are triploids and generally sterile, producing a small number of hybrid offspring. Observing the meiotic chromosome behaviors of ‘Bartzella’, an intersectional hybrid with high ornamental value and ...

High temperature-induced production of unreduced pollen and its cytological effects in Populus
Scientific Reports, 2017 Temperature change is of potential to trigger the formation of unreduced gametes. In this study, we showed that short periods of high temperature treatment can induce the production of 2n pollen in Populus pseudo-simonii Kitag.

Veterinary and Comparative Oncology, EarlyView.ABSTRACT Equine melanocytic neoplasms (EMN) are aggressive tumours characterised by high metastatic potential and limited therapeutic options available. However, the molecular mechanisms underlying their progression remain poorly understood. This study therefore presents the integrative phosphoproteomic analysis of EMN tissue, with the aim of ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

The Journal of Physiology, EarlyView.Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes
The Journal of Physiology, EarlyView.Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Crop Breeding and Applied Biotechnology, 2016 This study evaluated the mode of reproduction, the meiotic behavior and the pollen viability of three tetraploid plants (2n=4x=40) originated from somatic chromosome duplication of Paspalum notatum plants. The plant WKS 3 changed the mode of reproduction
