Haploid Bio-Induction in Plant through Mock Sexual Reproduction

iScience, 2020
Summary: Haploidization is invaluable for basic genetic research and crop breeding. The haploid bio-induction principle is an important topic that remains largely unexplored.

Generation and characterization of rice OsCENH3 mutants for haploid induction. [PDF]

Plant Cell Rep
CRISPR/Cas9-mediated modification of OsCENH3 induces aneuploidy but fails to trigger haploid formation in rice, underscoring limited efficiency and the need for strategy refinement. The centromeric histone H3 variant (CENH3) is essential for kinetochore assembly and accurate chromosome segregation during cell division.

THE DEVELOPMENT OF HOMOZYGOUS MAIZE LINES USING AN IN VIVO HAPLOID INDUCTION IN THE CROATIAN GERMPLASM

Poljoprivreda, 2019
The in vivo haploid induction has been widely applied to the maize breeding in recent decades, but it has not been used in the breeding programs in the Republic of Croatia by now. This study's objectives were to examine the haploid induction rates in the

Selection Gain of Maize Haploid Inducers for the Tropical Savanna Environments

Plants, 2021
Lacking elite haploid inducers performing high haploid induction rate (HIR) and agronomic performance is one of fundamental factors hindering the rapid adoption of doubled haploid technology in maize hybrid breeding, especially under tropical savanna ...

Morphological, cellular and molecular evidences of chromosome random elimination in vivo upon haploid induction in maize

Current Plant Biology, 2014
The mechanism of maternal in vivo haploid induction is not fully understood. In this study, the young embryos were identified by morphology, cytology and simple sequence repeat (SSR) markers at different developmental stages in the cross HZ514 (sweet ...

History and Current Status of Haploidization in Carrot (Daucus carota L.)

Agronomy, 2023
The induction of haploid cell development into normal plants enables the production of doubled haploid lines, which are homozygous and can be used in breeding programs as an alternative to conventionally derived inbred lines.

DNA-free genome editing for ZmPLA1 gene via targeting immature embryos in tropical maize

GM Crops & Food, 2023
Doubled haploid (DH) production accelerates the development of homozygous lines in a single generation. In maize, haploids are widely produced by the use of haploid inducer Stock 6, earlier reported in 1959.

Accelerated Breeding for Helianthus annuus (Sunflower) through Doubled Haploidy: An Insight on Past and Future Prospects in the Era of Genome Editing

Plants, 2023
The aim of any breeding process is to fully express the targeted, superior/desirable parent characteristic in the progeny. Hybrids are often used in this dynamic, and complex process for which homozygous parents—which may require up to eight generations ...

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

Molecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility

Advanced Science, EarlyView.
PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.
