Floral structure and systematics in four orders of rosids, including a broad survey of floral mucilage cells [PDF]
, 2018 Phylogenetic studies have greatly impacted upon the circumscription of taxa within the rosid clade, resulting in novel relationships at all systematic levels. In many cases the floral structure of these taxa has never been compared, and in some families,

Molecular Ecology, Volume 33, Issue 16, August 2024.Abstract Generalist plant‐feeding insects are characterised by a broad host repertoire that can comprise several families or even different orders of plants. The genetic and physiological mechanisms underlying the use of such a wide host range are still not fully understood.

Variation of terpene alkaloids in Daphniphyllum macropodum across plants and tissues
New Phytologist, Volume 243, Issue 1, Page 299-313, July 2024.Summary Daphniphyllum macropodum produces alkaloids that are structurally complex with polycyclic, stereochemically rich carbon skeletons. Understanding how these compounds are formed by the plant may enable exploration of their biological function and bioactivities.

Plant Direct, Volume 8, Issue 5, May 2024.Abstract Plants use chemistry to overcome diverse challenges. A particularly striking chemical trait that some plants possess is the ability to synthesize massive amounts of epicuticular wax that accumulates on the plant's surfaces as a white coating visible to the naked eye.

Molecular Phylogenetics of Phyllanthaceae: Evidence from Plastid MatK and Nuclear PHYC Sequences [PDF]
, 2005 Plastid matK and a fragment of the low-copy nuclear gene PHYC were sequenced for 30 genera of Phyllanthaceae to evaluate tribal and generic delimitation.

The legacy of terrestrial plant evolution on cell wall fine structure
Plant, Cell &Environment, Volume 47, Issue 4, Page 1238-1254, April 2024.Abstract The evolution of land flora was an epochal event in the history of planet Earth. The success of plants, and especially flowering plants, in colonizing all but the most hostile environments required multiple mechanisms of adaptation. The mainly polysaccharide‐based cell walls of flowering plants, which are indispensable for water transport and ...
