Quantitative classification of Camellia japonica and Camellia rusticana (Theaceae) based on leaf and flower morphology

open access: yesPlant Diversity, 2021
In Japan, Camellia japonica and Camellia rusticana are naturally distributed. Despite differences in their habitats and morphologies, they have been classified by various researchers as either varieties, subspecies, or species.

Combinatorial Roles of Heparan Sulfate Proteoglycans and Heparan Sulfates in Caenorhabditis elegans Neural Development [PDF]

open access: yes, 2014
Heparan sulfate proteoglycans (HSPGs) play critical roles in the development and adult physiology of all metazoan organisms. Most of the known molecular interactions of HSPGs are attributed to the structurally highly complex heparan sulfate (HS) glycans.

The Heterochronic Gene lin-14 Controls Axonal Degeneration in C. elegans Neurons

open access: yesCell Reports, 2017
The disproportionate length of an axon makes its structural and functional maintenance a major task for a neuron. The heterochronic gene lin-14 has previously been implicated in regulating the timing of key developmental events in the nematode C. elegans.

Apoplastic histochemical features of plant root walls that may facilitate ion uptake and retention

open access: yesOpen Life Sciences, 2021
We used brightfield and epifluorescence microscopy, as well as permeability tests, to investigate the apoplastic histochemical features of plant roots associated with ion hyperaccumulation, invasion, and tolerance of oligotrophic conditions.

Roots Structure and Development of Austrobaileya scandens (Austrobaileyaceae) and Implications for Their Evolution in Angiosperms [PDF]

open access: yes, 2020
Since the resolution of the ANA grade [Amborellales, Nymphaeales, Austrobaileyales] as sister to all other flowering plants, a few comparative studies of root structure have suggested that some of their anatomical traits could be of importance to ...

The genome of Romanomermis culicivorax:revealing fundamental changes in the core developmental genetic toolkit in Nematoda [PDF]

open access: yes, 2013
Background: The genetics of development in the nematode Caenorhabditis elegans has been described in exquisite detail. The phylum Nematoda has two classes: Chromadorea (which includes C. elegans) and the Enoplea.
