Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

A study of stomatal patterns in Plantago lanceolata L. Acer pseudoplatanus L. Sesleria caerulea L. in relation to environmental parameters [PDF]

open access: yes, 1991
A baseline study of leaf stomatal density, stomatal indices, guard cell length and leaf area was made in three species; a grass, Sesleria caerulea L., a herb, Plantago lanceolata L., and a tree, Acer pseudoplatanus L.

Future atmospheric CO2 leads to delayed autumnal senescence

open access: yes, 2007
Growing seasons are getting longer, a phenomenon partially explained by increasing global temperatures. Recent reports suggest that a strong correlation exists between warming and advances in spring phenology but that a weaker correlation is evident ...

The effects of different densities of pigweed (Amaranthus retroflexus) on growth indices of soybean (Glycine max L.)

open access: yesپژوهشهای زراعی ایران, 2009
To evaluate the interference of Red Root pigweed on growth indices of soybean cultivars an experiment was carried out in Research, Breeding and Providing of Seedling and Seed of Karaj institute during growing season of 2002.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Monitoring environmental features using leaf stomatal characteristics [PDF]

open access: yes, 1997
It is recognised that atmospheric CO(_2) concentrations are increasing, with concerns raised as to the global impact continued rises may have. Plant stomatal parameters have been suggested as a means of monitoring changing CO(_2) levels.

Infection of linseed by Alternaria linicola ; effects of inoculum density, temperature, leaf wetness and light regime

open access: yes, 1999
Controlled environment studies were conducted to determine the effects of inoculum density, temperature, leaf wetness and light regime on the infection of linseed by Alternaria linicola. The % cotyledons and leaves with symptoms, and the disease severity

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
