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.

ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.

Compatibility and Stability Analysis of Haploid Inducers under Different Source Germplasm and Seasons in Maize Using GGE Biplot

Agronomy
Multiple factors can affect the R1-nj purple kernel expression and seed set, reducing its efficiency in identifying haploids in maize. The complex interaction among the haploid inducer (HI), source germplasm (SG), and season (S) is inevitable in in vivo ...

Embryo and callus induction by different factors in ovary culture of cucumber

Journal of Applied Botany and Food Quality, 2017
Haploid and doubled haploid lines can be obtained in a short time using in vitro methods. In this study, unfertilized ovaries of cucumber were harvested and placed on semi-solid MS media as explants in Petri dishes.

The 3D genome of Gigaspora margarita unveils stable chromatin and nucleolar organization and symbiont‐dependent genome dynamics

New Phytologist, EarlyView.
Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...

Cultivating Callus from Anthers and Regenerating Haploid Plants in Lilium longiflorum

Horticulturae
In vitro anther culture is a technique used to produce haploid plants when regenerating varieties with specific traits. To generate haploid plants with preferred characteristics, an anther culture technique was established for Lilium longiflorum “Show Up”

Effect of F1 and F2 generations on genetic variability and working steps of doubled haploid production in maize.

PLoS ONE, 2019
For doubled haploid (DH) production in maize, F1 generation has been the most frequently used for haploid induction due to facility in the process. However, using F2 generation would be a good alternative to increase genetic variability owing to the ...

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes

New Phytologist, EarlyView.
Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...

Use of kernel dorsal basal pigmentation in the absence of crown pigmentation for haploid classification in maize using R1-nj-based haploid inducers

, 2022
Doubled haploid (DH) technology is growingly becoming an integral component of maize breeding programmes worldwide. The currently popular method of DH production employs R1-nj-based haploid inducers lines (HILs) that enable segregation of induction cross

Spatial inference of ancestor locations suggests northern refugia for canopy‐forming kelps in the Pacific Northwest

New Phytologist, EarlyView.
Population genetic structure in the Pacific Northwest for (a–c) Nereocystis and (d–f) Macrocystis. Summary Pockets of the formerly glaciated Pacific coastline of North America likely remained ice‐free throughout the Last Glacial Maximum (LGM). These areas may have served as refugia for terrestrial species, but less is known about their role in the ...
