steroid-hormone-signaling-in-plants-untangledPlants tend to “pump” up like major league baseball players do on steroids when they are given extra shots of brassinolide, the plant steroid. Researchers at the Salk Institute for Biological Studies while tracing signal of brassinolide deep into the cell’s nucleus unraveled how the growth-boosting hormone performs this job at the molecular level.

The Salk researchers, led by Joanne Chory, a professor in the Plant Molecular and Cellular Biology Laboratory and a Howard Hughes Medical Institute investigator, published their findings in the journal Nature.

Chory remarked that this study clarifies what happens in the downstream in the nucleus when brassinolide signals a plant cell to grow.

Antagonistic genes control growth of riceA plant steroid stimulates two genes – one suppressing the other for ensuring that leaves grow normally in rice and the experimental plant Arabidopsis thaliana, which is a relative of mustard – to battle against each other, as per scientists at the Carnegie Institution.

The results appeared in the December 15, 2009, issue of The Plant Cell and are considered to offer implications to understand as to how crop growth and yield can be manipulated.

The list of study colleagues were from the following institutions: Institute of Botany, Chinese Academy of Sciences; Chinese Academy of Agricultural Sciences; Department of Plant Biology, Carnegie Institution; Yonsei University, Korea; RIKEN Advanced Science Institute, Japan.

rice-growth-controlled-by-antagonistic-genesAccording to scientists at the Carnegie Institution, a plant steroid is responsible for prompting two genes to battle against each other – one suppressing the other for ensuring that leaves grow normally in rice and the experimental plant Arabidopsis thaliana, which is a relative of mustard.

The results are expected to have critical implications for understanding as to how crop growth and yield can be manipulated. These results appeared in the December 15, 2009, issue of The Plant Cell.
