Drastic mycorrhizal community shifts in Sceptridium ferns during the generation transition from fully mycoheterotrophic gametophytes to photosynthetic sporophytes

New Phytologist, Volume 245, Issue 4, Page 1705-1717, February 2025.
Summary Many plant species experience a prolonged subterranean phase during which they rely entirely on mycorrhizal fungi for carbon. While this mycoheterotrophic strategy spans liverworts, lycophytes, and ferns, most empirical research has centered on angiosperms.

Nahezu unendlich lange Polymere mit Ge=Ge‐Doppelbindungen

Angewandte Chemie, Volume 136, Issue 51, December 16, 2024.
Polymere mit Ge=Ge‐Doppelbindungen im σ,π‐Konjugationspfad werden über die Metathese schwererer acyclischer Diene (HADMET) aus Bis(digermenen) erhalten. Hohe Löslichkeit und Dispersionswechselwirkungen zwischen den Ketten ermöglichen nahezu unendliche Ketten und die Abscheidung als dünne Schichten mit geordneten lamellaren Bündeln.

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

New 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.
