Abstract:
Apocarotenoids are bioactive metabolites found in animals, fungi and plants. Several carotenoid-derived compounds, apocarotenoids, were recently identified as new growth regulators in different plant species. Here, we introduce basic chemical screening methods, using a model plant, Arabidopsis thaliana, to elucidate the function of bioactive apocarotenoids in determining plant phenotypic traits. These short guidelines include essential practices, such as selecting the plant growth conditions and the type of treatment, as well as phenotyping methodologies for the initial screening of novel apocarotenoid plant growth regulators.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
