Three closely linked X‐chromosomal genes potentially control sex determination in Cannabis sativa

open access: yesNew Phytologist, Volume 251, Issue 1, Page 505-522, July 2026.
Summary Sex determination mechanisms in dioecious plants remain poorly understood yet offer an excellent model system to study genetic changes underlying morphological evolution. We investigated the genetic basis of sex determination in Cannabis sativa, combining quantitative trait locus mapping in a segregating population, comparative transcriptomics ...

Establishment of a Single‐Cell Minimal Medium: A Case Study for Microfluidic Cultivation of Corynebacterium glutamicum

open access: yesBiotechnology and Bioengineering, Volume 123, Issue 6, Page 1648-1660, June 2026.
Conventional bulk media are often unsuitable for single‐cell cultivation and analysis because they provide excess nutrients or lack essential components. Redesigning the medium allows for controlled, defined growth, enabling the development of a robust minimal medium that supports quantitative and reproducible single‐cell analysis across different ...
