Improving the surface brightness-color relation for early-type stars using optical interferometry [PDF]

, 2014
The aim of this work is to improve the SBC relation for early-type stars in the $-1 \leq V-K \leq 0$ color domain, using optical interferometry. Observations of eight B- and A-type stars were secured with the VEGA/CHARA instrument in the visible.

Auxin response and PIN‐mediated transport in chlorophyte algae

Journal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Modeling the Action Potential in Characeae Nitellopsis obtusa: Effect of Saline Stress

Frontiers in Plant Science, 2019
Action potentials (AP) of characean cells were the first electrical transients identified in plants. APs provide information about plethora of environmental cues. Salinity stress is critical for plants and impacts on excitability.

In the Shadow of the Transiting Disk: Imaging epsilon Aurigae in Eclipse

, 2010
Eclipses of the single-line spectroscopic binary star, epsilon Aurigae, provide an opportunity to study the poorly-defined companion. We used the MIRC beam combiner on the CHARA array to create interferometric images during eclipse ingress.

Distribution and co-occurrence patterns of charophytes and angiosperms in the northern Baltic Sea

Scientific Reports, 2023
The distribution data of 11 soft substrate charophyte and angiosperm species were analyzed. Our study aimed to elucidate the co-occurrence patterns among these sympatric macrophyte species and quantify their distribution areas.

Is Chara corallina a suitable model plant for studying cell-failure mechanisms in fruit skins?

Journal of Applied Botany and Food Quality, 2021
The freshwater alga, Chara corallina, is often used as a model system in studies of cell-wall mechanics. Chara has a unique and very simple architecture, in which a number of node cells form the interface between two giant internode cells.

Validation of the Exoplanet Kepler-21b using PAVO/CHARA Long-Baseline Interferometry [PDF]

, 2012
We present long-baseline interferometry of the Kepler exoplanet host star HD179070 (Kepler-21) using the PAVO beam combiner at the CHARA Array. The visibility data are consistent with a single star and exclude stellar companions at separations ~1-1000 ...

Barley HvBODYGUARD1 controls cuticular specialisations regulated by SHINE transcription factors

New Phytologist, EarlyView.
Cuticle defects result from defective HvBDG1 alleles. Summary Land plants secrete a protective outer cuticular layer with diverse functions. Barley (Hordeum vulgare L.) develops two cuticular specialisations: the β‐diketone rich wax bloom on vegetative tissues and an adherent grain surface which sticks to the hulls, leading to barley's distinctive ...
