High‐Contiguity Haplotype‐Resolved Genome Assembly of the Hexaploid Actinidia valvata Rootstock Sheds Light on Waterlogging Resistance Gene

Plant Biotechnology Journal, EarlyView.
ABSTRACT Polyploidisation, creating redundant or diverged copies of the genome, is a major driving force in plant evolution, diversification and environmental adaptation, including for the kiwifruit genus (Actinidia Lindl.). We present a high‐contiguity, haplotype‐resolved genome assembly of the hexaploid Actinidia valvata rootstock cultivar ...

Converging GWAS and Genome Editing Decrypts MsCBF8‐MsGolS2 Regulatory Module for Drought Tolerance Without Yield Penalty in Medicago sativa

Plant Biotechnology Journal, EarlyView.
ABSTRACT Drought constitutes a major abiotic stress limiting alfalfa productivity. To elucidate the genetic basis of drought tolerance, a genome‐wide association study (GWAS) was conducted in alfalfa, which identified a CBF/DREB1 family transcription factor designated MsCBF8.

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Effects of the aurora kinase inhibitors AZD1152-HQPA and ZM447439 on growth arrest and polyploidy in acute myeloid leukemia cell lines and primary blasts

Haematologica, 2008
Background Aurora kinases play an essential role in the orchestration of chromosome separation and cytokinesis during mitosis. Small-molecule inhibition of the aurora kinases has been shown to result in inhibition of cell division, phosphorylation of ...

A Century of Understanding and Harnessing Heterosis

Plant Breeding, EarlyView.
ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Effects of Antimitotic Agents, Temperature and Immersion Time on Chromosome Doubling Efficiency in Supersweet Corn (Zea mays L. var. saccharata)

Plant Breeding, EarlyView.
ABSTRACT Doubled haploid technology accelerates the development of fully homozygous maize lines compared with conventional selfing. However, specific protocols for supersweet corn (Zea mays L. var. saccharata), particularly regarding immersion time in antimitotic solutions and temperature during chromosome doubling, remain poorly defined.

Improved Autotetraploid Induction Methods in Four Diploid Wild Peanut Species: Arachis duranensis, A. stenosperma, A. magna, and A. batizocoi

Plant Breeding, EarlyView.
ABSTRACT Peanut (Arachis hypogaea L., 2n = 4x = 40, AABB) is an important legume crop worldwide. Wild peanuts (Arachis spp.) represent a valuable secondary gene pool with diverse disease resistances. However, most wild peanut species are diploid (2n = 2x = 20) and this ploidy barrier is a major obstacle to hybridization and gene introgression.

Cultivar‐Specific Production of Unreduced Pollen in the Ornamental Bigleaf Hydrangea (Hydrangea macrophylla ssp. macrophylla)

Plant Breeding, EarlyView.
ABSTRACT Unreduced gametes naturally promote polyploidization and are valuable in breeding polyploid offspring. Bigleaf hydrangea (Hydrangea macrophylla ssp. macrophylla), a major ornamental crop, has shown spontaneous polyploidization rates ranging from 0% to 94% in previous crosses.

Stress‐specific metabolic and physiological responses to drought and waterlogging in Allium cepa L. and Allium × cornutum Clementi ex Vis.

Plant Biology, EarlyView.
Drought and waterlogging induce distinct species‐specific metabolic, physiological and transcriptional responses in Allium cepa and Allium × cornutum. Abstract Increasing variability in water availability, caused by changing climatic conditions, is a major constraint for onion production.
