This study aimed to investigate how low temperature alters the sex expression of monoecious cucumbers (Cucumis sativus L.). Plants were grown under different day/night temperature regimes, 28 °C/18 °C (12 h/12 h), 18 °C/12 °C, 28 °C/12 °C, and 28 °C/(6 h 18 °C+6 h 12 °C). It was found that plant femaleness is highest in the 28 °C/(6 h 18 °C+6 h 12 °C) treatment. Analysis of endogenous phytohorm...
We report a study on student’s attitudes to a visually androgynous in comparison to a male and a female Teachable Agent (TA). Results were that overall the androgynous agent was preferred over the female and male agents. A visually androgynous agent does not embody categorical gender attributes. At the same time it does not have to be genderless but instead represent both maleness and femalenes...
Background The male predominance in the prevalence of autism spectrum disorder (ASD) has motivated research on sex differentiation in ASD. Multiple sources of evidence have suggested a neurophenotypic convergence of ASD-related characteristics and typical sex differences. Two existing, albeit competing, models provide predictions on such neurophenotypic convergence. These two models are testabl...
Some genes regulate phenotypes that are either present or absent. They are often important regulators of developmental switches and are involved in morphological evolution. We have little understanding of the molecular mechanisms by which these absence/presence gene functions have evolved, because the phenotype and fitness of molecular intermediate forms are unknown. Here, we studied the sex-de...
The effects of 2-chloroethylphosphonic acid (Ethrel), ethylene, and some growth retardants on sex expression of cucumber plants (Cucumis sativus L.) were investigated, with the use of a monoecious cultivar (Improved Long Green) which has a strong tendency toward maleness.Ethrel caused increased femaleness when applied at 50 milligrams per liter at the first to the third leaf stage, but when app...
