Programmable Domestication: CRISPR, Pan‐Genomics and System Level Engineering for Next‐Generation Crops

Plant Biotechnology Journal, EarlyView.
Conceptual overview of programmable de novo domestication from genetic diversity discovery to crop deployment. The framework connects diverse germplasm and genomic resources with three trajectory pathways. Adaptive Rescue, Agronomic Refinement and Novel Chassis defined by biological distance, engineering complexity and breeding objectives.

Induction of Quercus ilex L. haploid and doubled-haploid embryos from anther cultures by temperature-stress

, 2013
This paper describes a method to obtain haploid and doubled-haploid (DH) embryos using anther cultures of holm oak (Quercus ilex L.). The production of haploids and DH through gametic embryogenesis provides an attractive biotechnological tool for ...

Gap‐Free Cannabis sativa Assemblies Reveal Post‐Polyploid Genome Remodelling and Refine the Evolution of Cannabinoid Synthase Genes

Plant Biotechnology Journal, EarlyView.
ABSTRACT Despite the therapeutic importance of cannabinoids, the scarcity of gap‐free Cannabis genomes has limited the dissection of the genetic and genomic basis of cannabinoid biosynthesis and genome evolution. Here, we generated two haplotype‐phased, gap‐free, gold‐standard assemblies and used them to investigate post‐polyploid genome remodelling ...

In vivo HAPLOID INDUCTION AND EFFICIENCY OF TWO CHROMOSOME DUPLICATION PROTOCOLS IN TROPICAL MAIZE

Ciência e Agrotecnologia, 2015
Artificial chromosome duplication is one of the most important process in the attainment of doubled haploids in maize. This study aimed to evaluate the induction ability of the inducer line KEMS in a tropical climate and test the efficiency of the R1 ...

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.

Genomewide association study of haploid female fertility (HFF) and haploid male fertility (HMF) in BS39-derived doubled haploid maize lines [PDF]

Key messageRestoration of haploid female and haploid male fertility without colchicine is feasible. Three SNPs and eight gene models for HFF, and one SNP and a gene model for HMF were identified.

Genomic Selection for Haploid Induction Rate in Tropical Maize (Zea mays L.) Haploid Inducer Populations: Insights From Heterotic Pools and Recurrent Selection Cycles

Plant Breeding, EarlyView.
ABSTRACT Doubled‐haploid (DH) technology based on in vivo haploid induction has become an effective strategy for accelerating maize breeding. However, improving haploid inducer populations remains challenging because accurate estimation of haploid induction rate (HIR) requires labour‐intensive phenotypic validation, while putative HIR estimates are ...

Characterizing the genomic consequence of diploid-to-haploid induction in potato using large-scale whole-genome sequencing

Reinventing the tetraploid potato as an inbred-line-based diploid crop has become an increasingly attractive strategy to accelerate genetic gain in potato breeding.
