An Angiosperm species dataset reveals relationships between seed size and two-dimensional shape [PDF]

, 2019
Datasets containing information on seed size have been published and are currently available. Nevertheless, there is a lack in the literature of a dataset dedicated to seed shape. We present a preliminary version for a dataset on seed morphology based on

Insecticidal effect of the ethanol extract of Baccharis dracunculifolia (Asterales: Asteraceae)

Revista de Biología Tropical, 2017
Insecticides from plants have been studied as an alternative in agricultural production and in vector control of human diseases. The use of botanical insecticides may cause mortality in different stages, slow growth, infertile adults and decrease in viability of insect eggs.

Interstitial Arabidopsis-Type Telomeric Repeats in Asteraceae

Plants, 2021
Tandem repeats of telomeric-like motifs at intra-chromosomal regions, known as interstitial telomeric repeats (ITR), have drawn attention as potential markers of structural changes, which might convey information about evolutionary relationships if ...

INDEPENDENT ORIGINATION OF FLORAL ZYGOMORPHY, A PREDICTED ADAPTIVE RESPONSE TO POLLINATORS: DEVELOPMENTAL AND GENETIC MECHANISMS [PDF]

, 2016
Observations of floral development indicate that floral organ initiation in pentapetalous flowers more commonly results in a medially positioned abaxial petal (MAB) than in a medially positioned adaxial petal (MAD), where the medial plane is defined by ...

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

PLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

Genome duplications, genomic conflict, and rapid phenotypic evolution characterize the Cretaceous radiation of Fagales

Journal of Integrative Plant Biology, EarlyView.
Fagales show “early burst” model of phenotypic disparification, with morphospace being filled during the early radiation of the Fagales crown and its major families. The elevated levels of phenotypic evolution often correspond to hotspots of gene duplication, whereas species diversification is decoupled from both phenotypic and genomic evolution ...
