The Saururus chinensis genome provides insights into the evolution of pollination strategies and herbaceousness in magnoliids. [PDF]

open access: yesPlant J, 2023
SUMMARY Saururus chinensis, an herbaceous magnoliid without perianth, represents a clade of early‐diverging angiosperms that have gone through woodiness–herbaceousness transition and pollination obstacles: the characteristic white leaves underneath inflorescence during flowering time are considered a substitute for perianth to attract insect ...

Historical contingency via priority effects counteracts environmental change on metacommunity dynamics across decades [PDF]

open access: yesLimnology and Oceanography, Volume 67, Issue S1, Page S38-S53, February 2022., 2022
Community ecology has had a strong focus on single snapshots of species compositional variation in time. However, environmental change often occurs slowly at relatively broad spatio-temporal scales, which requires historically explicit assessments of ...

Is there silicon in flowers and what does it tell us? [PDF]

open access: yesEcol Evol, 2023
Whether flowers accumulate Si and what the implications may be was largely unknown. We analysed the flowers separated into their different anatomical parts, and leaves of different taxa. We conclude that flowers contain Si, in large amounts for some species, and hence the function of this element warrants more attention.

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration. [PDF]

open access: yesPlant Environ Interact
Exponential 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‐

Angiosperm flowers reached their highest morphological diversity early in their evolutionary history. [PDF]

open access: yesNew Phytol
Summary Flowers are the complex and highly diverse reproductive structures of angiosperms. Because of their role in sexual reproduction, the evolution of flowers is tightly linked to angiosperm speciation and diversification. Accordingly, the quantification of floral morphological diversity (disparity) among angiosperm subgroups and through time may ...

Direct and indirect effects of fenoxycarb on freshwater systems dominated by Neocaridina palmata (Decapoda: Atyidae) and macrophyte Ceratophyllum demersum

open access: yesEcotoxicology and Environmental Safety, 2021
Few studies have been conducted with regard to the effects of insecticides on population dynamics of shrimps and associated groups such as macrophytes, phytoplankton, microorganisms etc. In the present study, effects of a single application of fenoxycarb

Is There a Key Primer for Amplification of Core Land Plant DNA Barcode Regions (rbcL and matK)? [PDF]

open access: yesEcol Evol
We use in silico PCR to select and measure the amplification capability of primer. We tested 366 and 489 published primers for the rbcL and matK regions, respectively, using sequences from 8463 different land plant species. Our results indicate a set of primers that effectively cover all land plant sequences, particularly for the rbcL region.

Impact of hydrotechnical construction on aquatic ecosystems of the Kiliia branch of the Danube Delta [PDF]

open access: yes, 2022
Resumption of shipping in the Bystryi branch in the Ukrainian part of the Danube Delta, one of the largest aquatic-wetland areas of Europe and the world, has made it necessary to control the anthropogenic impact on the neighboring water areas of the ...

A Group 6 LEA Protein Plays Key Roles in Tolerance to Water Deficit, and in Maintaining the Glassy State and Longevity of Seeds. [PDF]

open access: yesPlant Cell Environ
ABSTRACT Plants have a wide range of adaptive and protective mechanisms to cope with dehydration. Central in these processes are the Late Embryogenesis Abundant (LEA) proteins, whose levels notably increase in response to dehydration during seed development and vegetative tissues.
