Spermatophyta Molecular Clock: Time Drift and Recent Acceleration. [PDF]
Plant Environ InteractExponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

An eDNA Survey of Plant Biodiversity in a Local Dam Within South Africa's Largest City. [PDF]
Ecol EvolEcological information is needed to establish, implement and monitor such biodiversity management plans. This study employs environmental DNA to provide a good overview of plant community structure in an urban dam in Johannesburg, South Africa. It further reveals a gap in the taxonomic coverage of South African plants on public DNA databases.

Ecological Isolation Maintains the Species Boundaries Between Two Sympatric <i>Cycas</i> From Southwest China. [PDF]
Ecol EvolThe study reveals that sympatric Cycas species (C. pectinata and C. simplicipinna) maintain strict species boundaries without hybridization, driven by reproductive isolation mechanisms (divergent coning times and pollinator specificity) and ecological niche differentiation (habitat preferences, soil pH differences).

Cryptic signals: substomatal architecture influences stomatal responses to red light and CO2 [PDF]
New Phytologist.Summary The mesophyll provides a critical signal for stomatal responses to red light (RL) and CO2 in angiosperms. By contrast, the stomatal response to blue light (BL) is largely guard cell‐specific. It is not known whether substomatal or mesophyll anatomy influences the effectiveness of the mesophyll signal driving stomatal responses to RL and CO2 ...

Eobowenia gen. nov. from the early Cretaceous of Patagonia: indication for an early divergence of Bowenia? [PDF]
, 2017 Background: Even if they are considered the quintessential "living fossils", the fossil record of the extant genera of the Cycadales is quite poor, and only extends as far back as the Cenozoic.
