Development of doubled haploid inducer lines facilitates selection of superior haploid inducers in maize

Frontiers in Plant Science
Haploid inducers are key components of doubled haploid (DH) technology in maize. Robust agronomic performance and better haploid induction ability of inducers are persistently sought through genetic improvement. We herein developed C1-I inducers enabling

A Robust Framework for Maize Elite Line Genome Editing Through Enhanced HI‐Edit via LbCas12a Activity Optimization

Plant Biotechnology Journal, EarlyView.
ABSTRACT Haploid induction coupled with genome editing (HI‐Edit) enables direct modification of commercial crop varieties, bypassing the need for trait introgression or direct transformation of elite lines with CRISPR machinery. However, its widespread application has been constrained by low haploid editing rates (HER), the proportion of haploids ...

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 ...

Maternal Haploid Induction Through Egg Cell‐Specific Endopeptidases in Brassica napus: A Step Forward Towards Hybrid Fixation

Food and Energy Security
Hybrid fixation is an emerging breeding tool that eliminates the need to purchase costly hybrid seeds on an annual basis. However, this technique is limited to Arabidopsis, rice, and soybean with a severe issue of seed setting.

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.

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 ...

POSIBILITĂŢI DE AMELIORARE A LINIILOR DE INDUCERE A HAPLOIZILOR LA PORUMB

Studia Universitatis Moldaviae: Stiinte reale si ale naturii, 2009
Recently, rather high effective maternal-haploid inducers have been created. However, there is a need for their further improvement. New inducers should possess a higher frequency of haploid induction, improved agronomic traits and good expression of ...

Improvements of doubled haploid production protocol for white cabbage (Brassica oleracea var. capitata L.)

Folia Horticulturae, 2018
Protocols leading to the development of doubled haploid (DH) lines by microspore culture are widely used in white cabbage (Brassica oleracea var. capitata L.), but efficiency varies according to the cultivar and induction procedure.

Critical Windows of Air Pollution Exposure During Spermatogenesis and Intrauterine Insemination Outcomes

Paediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Male preconception health remains a critically under‐addressed area of family planning. While research suggests air pollution may harm semen quality, downstream impacts on pregnancy, particularly for more vulnerable infertility treatment populations, are understudied.

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 ...
