FIGL1 prevents aberrant chromosome associations and fragmentation and limits crossovers in polyploid wheat meiosis

open access: yesNew Phytologist, Volume 244, Issue 2, Page 528-541, October 2024.
Summary Meiotic crossovers (COs) generate genetic diversity and are crucial for viable gamete production. Plant COs are typically limited to 1–3 per chromosome pair, constraining the development of improved varieties, which in wheat is exacerbated by an extreme distal localisation bias.

The transcription factor LBD10 sustains pollen tube growth and integrity by modulating reactive oxygen species homeostasis via the regulation of flavonol biosynthesis in Arabidopsis

open access: yesNew Phytologist, Volume 244, Issue 1, Page 131-146, October 2024.
Summary Reproduction in angiosperms relies on the precise growth of pollen tubes, facilitating the delivery of sperm cells to the ovule for double fertilization. LATERAL ORGAN BOUNDARIES DOMAIN10 (LBD10), a plant‐specific transcription factor, plays a pivotal role in Arabidopsis pollen development.

Unravelling the unusual: chromosome elimination, nondisjunction and extra pollen mitosis characterize the B chromosome in wild sorghum

open access: yesNew Phytologist, Volume 243, Issue 5, Page 1840-1854, September 2024.
Summary The B chromosomes exhibit diverse behaviour compared with conventional genetic models. The capacity of the B chromosome either to accumulate or to be eliminated in a tissue‐specific manner is dependent on biological processes related to aberrant cell division(s), but here yet remains compatible with normal development.
