Developmental Flower and Rhizome Morphology in Nuphar (Nymphaeales): An Interplay of Chaos and Stability

open access: yesFrontiers in Cell and Developmental Biology, 2020
European species of Nuphar are amongthe most accessible members of the basal angiosperm grade, but detailed studies using scanning electron microscopy are lacking. We provide such data and discuss them in the evolutionary context. Dorsiventral monopodial

Early Cretaceous angiosperms and beetle evolution [PDF]

open access: yes, 2013
The Coleoptera (beetles) constitute almost one-fourth of all known life-forms on earth. They are also among the most important pollinators of flowering plants, especially basal angiosperms.

Stomatal patterning in angiosperms [PDF]

open access: yesAmerican Journal of Botany, 2000
My thesis is that understanding stomatal patterning requires a holistic perspective. Since stomata are structures critical to the survival of terrestrial plants, they need to be viewed in relation to their function and their interface with other structural components.

An insight to strategical responses of particulate pollution in plants: From phenome to genome

open access: yesPlant Stress
Particulate matter (PM) is an extremely overlooked air pollutant with drastic effects on the biome, owing to the industrial and agricultural advancements, significantly exacerbating global environmental contamination levels.

A targeted capture approach to generating reference sequence databases for chloroplast gene regions

open access: yesEcology and Evolution, 2022
Metabarcoding has improved the way we understand plants within our environment, from their ecology and conservation to invasive species management. The notion of identifying plant taxa within environmental samples relies on the ability to match unknown ...

Deconstructing age estimates for angiosperms [PDF]

open access: yes, 2023
Estimates of the age of angiosperms from molecular phylogenies vary considerably. As in all estimates of evolutionary timescales from phylogenies, generating these estimates requires assumptions about the rate that molecular sequences are evolving (using

A Flower Bud from the Lower Cretaceous of China

open access: yesBiology, 2022
Background: Although various angiosperms (including their flowers) have been reported from the Yixian Formation (Lower Cretaceous) of China, which is famous worldwide for its fossils of early angiosperms, no flower bud has hitherto been seen in the Early

Bringing to light the molecular evolution of GUX genes in plants [PDF]

open access: yesGenetics and Molecular Biology, 2020
Hemicellulose and cellulose are essential polysaccharides for plant development and major components of cell wall. They are also an important energy source for the production of ethanol from plant biomass, but their conversion to fermentable sugars is ...
