Evolution of molecular communication in the permanent Azolla symbiosis
New Phytologist, Volume 249, Issue 4, Page 1666-1674, February 2026.Summary Heritable symbioses exist across eukaryotes with different degrees of intimacy. In most cases, the symbionts are obligate and require inheritance for their survival. On the host side, symbiont retention can facilitate fitness benefits. Only rarely are these symbioses interwoven to the point that host survival relies on the symbiont.

Loss of E3 ligase HvST1 function substantially increases distal crossover frequency
New Phytologist, Volume 249, Issue 3, Page 1325-1341, February 2026.Summary This study characterizes the function of a grass‐specific E3 ubiquitin ligase, HvST1, in regulating synapsis and crossover (CO) formation during meiosis in barley (Hordeum vulgare). In large‐genome cereals, COs are predominantly restricted to distal chromosomal regions, limiting genetic recombination and breeding flexibility.

New Phytologist, Volume 249, Issue 1, Page 448-459, January 2026.Summary Mycorrhizal associations between fungi and plants are a fundamental aspect of terrestrial ecosystems. Mycorrhizas occur in c. 85% of extant plants, yet their geological record remains sparse. Rare fossil evidence from early terrestrial environments offers crucial insights into these ancient symbioses, but visualizing fossil fungi at the ...

New Phytologist, Volume 248, Issue 6, Page 3191-3207, December 2025.Summary Plant cell walls constitute a major defence barrier against pathogens, although it is unclear how specific cell wall components impact pathogen colonisation. Pathogens secrete cell wall‐degrading enzymes (CWDEs) to facilitate plant colonisation, but damaged or infected cells are often a source of cell wall‐derived oligosaccharides that trigger ...
