Tissue-specific auxin signaling in response to temperature fluctuation

Transgenic Zebrafish Reveal Tissue-Specific Differences in Estrogen Signaling in Response to Environmental Water Samples

BACKGROUND Environmental endocrine disruptors (EEDs) are exogenous chemicals that mimic endogenous hormones such as estrogens. Previous studies using a zebrafish transgenic reporter demonstrated that the EEDs bisphenol A and genistein preferentially activate estrogen receptors (ERs) in the larval heart compared with the liver. However, it was not known whether the transgenic zebrafish reporter ...

A role for auxin response factor 19 in auxin and ethylene signaling in Arabidopsis.

Although auxin response factors (ARFs) are the first well-characterized proteins that bind to the auxin response elements, elucidation of the roles of each ARF gene in auxin responses and plant development has been challenging. Here we show that ARF19 and ARF7 not only participate in auxin signaling, but also play a critical role in ethylene responses in Arabidopsis (Arabidopsis thaliana) roots...

Seedling emergence response to temperature in safflower: measurements and modeling

Quantitative information about the response of seedling emergence totemperature for safflower (Carthamus tinctorius L.) is rare. The main objective ofthe present study was to develop a model for predicting days to emergence forsafflower as influenced by the temperature. In this regard, a field experiment with arange of sowing dates and four safflower cultivars were conducted to describe theresp...
