Diverse ecological functions and the convergent evolution of grass awns
American Journal of Botany, Volume 109, Issue 9, Page 1331-1345, September 2022., 2022 Abstract The awn of grasses is a long, conspicuous outgrowth of the floral bracts in a grass spikelet. It is known to impact agricultural yield, but we know little about its broader ecological function, nor the selective forces that lead to its evolution. Grass awns are phenotypically diverse across the extant ~12,000 species of Poaceae. Awns have been

Lateral transfers lead to the birth of momilactone biosynthetic gene clusters in grass
The Plant Journal, Volume 111, Issue 5, Page 1354-1367, September 2022., 2022 SUMMARY Momilactone A, an important plant labdane‐related diterpenoid, functions as a phytoalexin against pathogens and an allelochemical against neighboring plants. The genes involved in the biosynthesis of momilactone A are found in clusters, i.e., momilactone A biosynthetic gene clusters (MABGCs), in the rice and barnyardgrass genomes.

Fire‐released seed dormancy ‐ a global synthesis
Biological Reviews, Volume 97, Issue 4, Page 1612-1639, August 2022., 2022 ABSTRACT Seed dormancy varies greatly between species, clades, communities, and regions. We propose that fireprone ecosystems create ideal conditions for the selection of seed dormancy as fire provides a mechanism for dormancy release and postfire conditions are optimal for germination.

Fate of Microplastic Captured in the Marine Demosponge Halichondria Panicea [PDF]
Marine Pollution Bulletin, 2023 Microplastic particles are widespread pollutants in the sea and filter-feeding sponges have recently been suggested as useful monitoring organisms. However, the fate of microplastic particles in sponges is poorly understood, yet crucial for interpreting monitoring data.
