Molecular and morphological phylogenetics of the digitate-tubered clade within subtribe Orchidinae s.s. (Orchidaceae: Orchideae) [PDF]

, 2018
The digitate-tubered clade (Dactylorhiza s.l. plus Gymnadenia s.l.) within subtribe Orchidinae is an important element of the North-temperate orchid flora and has become a model system for studying the genetic and epigenetic consequences of organism-wide

Homologous recombination mutants cause differing lethality between h− and h+ Schizosaccharomyces pombe strains due to mat1 heterochromatin

The FEBS Journal, EarlyView.
Homologous recombination (HR) in Schizosaccharomyces pombe is essential when mating‐type switching–induced double‐strand breaks (DSBs) form at the mat1 locus. In h90 and h− strains, efficient mat1 DSB formation renders HR indispensable unless suppressors block these breaks.

Polyploid races, genetic structure and morphological features of the earthworm Octodrіlus transpadanus (Rosa, 1884) (Oligohaeta: Lumbricidae) in the Ukraine [PDF]

, 2009
Kariological investigation of the earthworm Octodrilus transpada-nus (Rosa, 1884) in the Ukraine showed that this species is represented by at least three races of different ploidy with the basic chromosome number n=15. Strict geographic heterogeneity

Crossing Lilium Orientals of different ploidy creates Fusarium-resistant hybrid [PDF]

, 2010
Oriental hybrid lily is of great commercial value, but it is susceptible to Fusarium disease that causes a significant loss to the production. A diploid Oriental hybrid resistant to Fusarium, Cai-74, was diploidized from triploid obtained from the ...

The physiological response of juvenile diploid and triploid Arctic charr Salvelinus alpinus to exhaustive exercise

Journal of Fish Biology, EarlyView.
Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.

Unreduced megagametophyte production in lemon occurs via three meiotic mechanisms, predominantly second-division restitution [PDF]

, 2017
Unreduced (2n) gametes have played a pivotal role in polyploid plant evolution and are useful for sexual polyploid breeding in various species, particularly for developing new seedless citrus varieties.

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Application of Flow Cytometry to Determine Cell DNA Content in the Genetic Breeding of Fish

Fishes
In the field of fish genetic breeding, accurately determining the DNA content and ploidy of fish is of great significance. This article introduces the use of flow cytometry (FCM) to measure the DNA content and conduct ploidy analysis by sampling ...

High‐throughput multispecies quantitative polymerase chain reaction assays to study the effects of acute thermal stress in three species of Acipenser sturgeon

Journal of Fish Biology, EarlyView.
Abstract Fishes experience thermal stress in their natural environment that can be caused by natural or anthropogenic factors and can directly affect their physiology. In this study, we developed a multispecies OpenArray™ qPCR (quantitative polymerase chain reaction) ‘chip’ to measure the effects of acute thermal stress on the mRNA response of ...

Pangenome analysis reveals the genetic mechanism underlying high‐altitude adaptation in Qinghai–Xizang (Tibet) Plateau Rhododendron

Journal of Integrative Plant Biology, EarlyView.
Pan‐genome analysis reveals that high‐altitude Rhododendron species resist alpine cold stress by rapidly sensing and engaging the chilling response pathway and genes that directly and indirectly protect the plant from UV radiation. Heritable genomic features such as long terminal repeats contribute to the adaptive diversification of Rhododendron ...
