The use of deidentified organ donor testes for research

Andrology, Volume 14, Issue 8, Page 2359-2372, November 2026.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

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,

Cultural techniques to increase survivability and vigor in Zea mays l. doubled haploids

, 2010
The embryo rescue technique in combination with doubled haploids can be a valuable tool to hasten inbred creation and thus reduce the generational time.

Chromosome doubling of barley haploids by nitrous oxide and colchicine treatments

, 1975
Hybridization of Hordeum vulgare L. (2n = 14) with H. bulbosum L. (2n = 14) results in a high frequency of haploids of H. vulgare through selective elimination of H. bulbosum chromosomes.

Comparative genomics reveals lineage‐associated structural variation and diversification in a barley fungal pathogen

New Phytologist, Volume 252, Issue 4, Page 1565-1583, November 2026.
Genome‐wide copy‐number variation landscape highlights structural divergence across Puccinia hordei isolates and potentially links Cyp51 amplification to fungicide insensitivity. Summary Leaf rust, caused by Puccinia hordei, is a major barley disease worldwide.

The male gamete as a tool in the genetic improvement of cereals

, 1989
This review surveys recent developments in the use of male gametes for the genetic improvement of cereals. It focuses mainly on the production of doubled haploids and their use in breeding programmes but also discusses gametoclonal variaton, in vitro ...

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

Journal of Phycology, Volume 62, Issue 5, Page 1536-1563, October 2026.
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 ...

Linking variation in genome size to cyst size in chrysophytes

Journal of Phycology, Volume 62, Issue 5, Page 1671-1682, October 2026.
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, Volume 252, Issue 2, Page 575-587, October 2026.
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.

The cold case of state transition 7 (stt7) mutants of Chlamydomonas reinhardtii, solved by whole‐genome sequencing

New Phytologist, Volume 252, Issue 1, Page 145-162, October 2026.
Long‐read whole‐genome sequencing revealed extensive chromosomal rearrangements and aneuploidy in a widely used Chlamydomonas reinhardtii stt7‐1 mutant. The STT7 gene (shown in red) was found to be split between two rearranged chromosomes, providing a molecular explanation for the long‐standing failure of this mutant in genetic crosses.
