Membranous Interacting Partners of Phage-Type Plastid RNA Polymerase Have Limited Impact on Plastid Gene Expression During Chloroplast Development. [PDF]

open access: yesPlant Direct
ABSTRACT In vascular plants, genes in the plastid genome are transcribed by two types of RNA polymerases, namely, phage‐type nuclear‐encoded and bacterial‐type plastid‐encoded plastid RNA polymerases (NEP and PEP, respectively). Eudicots, including Arabidopsis, carry two isoforms of NEP, RPOTp and RPOTmp.

Plant traits and environment: floating leaf blade production and turnover of waterlilies [PDF]

open access: yesPeerJ, 2017
Floating leaf blades of waterlilies fulfill several functions in wetland ecosystems by production, decomposition and turnover as well as exchange processes. Production and turnover rates of floating leaf blades of three waterlily species, Nuphar lutea (L.

Phylogenetic Relatedness Determines Heterospecific Pollen-Pistil Compatibility and Reproductive Outcome in the Apocarpous Species <i>Sagittaria trifolia</i> (Alismataceae). [PDF]

open access: yesEcol Evol
This study investigates heterospecific pollen (HP) effects in Sagittaria trifolia, an apocarpous plant with an extragynoecial compitum. HP–pistil compatibility and resulting seed set reduction were greatest from phylogenetically close donors, not influenced by origin or pollen traits.

Synthesis and Sulfur Electrophilicity of the Nuphar Thiaspirane Pharmacophore

open access: yesACS Central Science, 2016
We describe a general method to synthesize the iminium tetrahydrothiophene embedded in the dimeric Nuphar alkaloids. In contrast to prior studies, the sulfur atom of the thiaspirane pharmacophore is shown to be electrophilic. This α-thioether reacts with thiophenol or glutathione at ambient temperature to cleave the C-S bond and form a disulfide. Rates

Initial decomposition of floating leaf blades of waterlilies: causes, damage types and impacts [PDF]

open access: yesPeerJ, 2019
The initial decomposition of large floating-leaved macrophytes, such as waterlilies, can be studied by following changes in leaf damage and area loss of leaf blades tagged in their natural environment.
