Quantitative chemobiology: a guide into the understanding of plant bioactivity

Journal of the Brazilian Chemical Society, 2002
Nothing is more important for human survival today, than understanding nature's mechanisms via a chemo-biological language. This multidisciplinary approach is a complex operation, because it involves integration of several levels of organization, such as

Bridging micro and macroevolution: insights from chromosomal dynamics in plants

Frontiers in Plant Science
Understanding the relationship between macro- and microevolutionary processes and their delimitation remains a challenge. This review focuses on the role of chromosomal rearrangements in plant population differentiation and lineage diversification ...

and light stomatal responses of angiosperms compared to ferns

, 2019
Stomatal responses to environmental signals differ substantially between ferns and angiosperms. However, the mechanisms that lead to such different responses remain unclear.

Larval character evolution in Holometabola (Insecta)

Cladistics, EarlyView.
Abstract Larvae, a novel type of immature stage, are a crucial innovation of the Holometabola. Larval features therefore provide key evidence for reconstructing evolutionary transformations in this megadiverse group. Here we present the first formal reconstruction of larval character evolution, using maximum parsimony and Bayesian ancestral‐state ...

Heterospory and the Angiosperms [PDF]

Nature, 1932
FOR many years it has been generally assumed by botanists that in Angiosperms, as in the heterosporous Pteridophytes, the megaspores are larger than the microspores. In a study of megaspore development in Œnothera rubricalyx (Gates and Sheffield),1 it was incidentally discovered that this is not the case.

Species diversity and host plant associations of ambrosia beetles in Southeast Asian forests of Laos and Vietnam revealed by DNA barcoding

Insect Conservation and Diversity, EarlyView.
Integrative DNA barcoding of ambrosia beetles and host plants revealed 27 beetle species across 16 genera and extensive, previously undocumented host plant diversity in Laos and Vietnam. Host specificity varied widely among ambrosia beetles, with Xylosandrus crassiusculus emerging as a dominant generalist associated with 19 host species from 12 plant ...

Floral Trait Influence on the Foraging Decisions of a Fly Pollinator

Journal of Applied Entomology, EarlyView.
ABSTRACT Flies foraging for floral resources provide important ecosystem services through the pollination of myriad angiosperms, including many crop species. However, the specific floral cues used by fly pollinators to locate and discriminate among floral rewards and the preferences they may have for specific cues remain poorly understood.

Simultaneous Inference of Flora-Wide Nuclear and Plastid Phylogenies Using Angiosperms353 Sequence Capture Data. [PDF]

Mol Ecol Resour
ABSTRACT Accurate knowledge of phylogenetic relationships and divergence time among plant species composing a regional flora is crucial for understanding the origin of the biodiversity patterns we observe today. Despite advances in phylogenomics, resources available for reconstructing regional phylogenies are still largely incomplete and poorly ...

Petrifactions of the Earliest European Angiosperms [PDF]

Nature, 1912
Abstract The paper records the existence of Angiosperins in England in Aptian times, i.e. at a geological period when they have been hitherto supposed not to exist in Northern Europe; describes botanically the anatomy of these fossils, which come under three new genera; and notes the points of structural and phylogenetic interest in ...
