Haploid identification in maize

Frontiers in Plant Science
Doubled haploid (DH) line production through in vivo maternal haploid induction is widely adopted in maize breeding programs. The established protocol for DH production includes four steps namely in vivo maternal haploid induction, haploid identification,

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.

Accelerating haploid induction rate and haploid validation through marker-assisted selection for qhir1 and qhir8 in maize

Frontiers in Plant Science
Doubled haploid (DH) technology becomes more routinely applied in maize hybrid breeding. However, some issues in haploid induction and identification persist, requiring resolution to optimize DH production.

Recent advances in the genomics of sugarcane (Saccharum)

Journal of Integrative Plant Biology, EarlyView.
This review systematically summarizes advances in sugarcane genomics, evolution, classification, and breeding practices. It identifies key research bottlenecks and proposes an integrated research framework to facilitate predictive sugarcane breeding, which provides valuable references for genetic improvement of other complex polyploid crops.

Haploids can be induced in knockout mutants of OsPLA1, but not OsDMP3 or OsDMP6, in rice

Crop Journal
Doubled haploid (DH) technology is an important tool in crop breeding because it can significantly accelerate the breeding process. ZmPLA1/MATL/NLD and ZmDMP are two key genes controlling haploid induction (HI) in maize, exhibiting a synergistic effect ...

In vitro androgenesis in triticale

The EuroBiotech Journal, 2017
The technology for in vitro anther culturing was optimized in hexaploid triticale using combination of external factors that allowed to obtain more than 100 doubled haploid lines.

The consequences of partial clonality on the spatiotemporal genetic structure of the red alga Chondria tumulosa (Ceramiales, Rhodophyta)

Journal of Phycology, EarlyView.
Abstract The relative rates of sexual versus clonal reproduction partition genetic diversity, but the quantification of these rates remains limited in natural populations. This knowledge gap is particularly acute among tropical macroalgae. Chondria tumulosa is a red macroalga that has been documented at high abundance in the three northernmost atolls ...

Improvement of haploid and doubled haploid plants using wheat anther culture

Revue Marocaine des Sciences Agronomiques et Vétérinaires, 2018
The production of haploids and double haploids, are widely used techniques in advanced breeding programs to speed-up the production of homozygote lines. Anther culture is one of the processes of induction and regeneration of haploids and double haploids ...

Linking variation in genome size to cyst size in chrysophytes

Journal of Phycology, EarlyView.
Abstract Genome size varies tremendously across eukaryotes, which often contain far more DNA than expected from their biological complexity. To explain this paradox, selection‐based hypotheses propose that genome size evolves through selection acting on life‐history traits correlated with the phenotypic effects, independent of its genic content.

Cell‐based crop phenotyping for future climates

New Phytologist, EarlyView.
Flow‐chart diagram illustrating the proposed pathway for improving the throughput of fluorescence imaging‐based phenotyping by using robotics and machine learning (ML) approaches. Summary Abiotic stress tolerance has been significantly weakened in modern crops during the domestication process.
