Ethylene is a gaseous hormone involved in many aspects of the growth and
development of plants. Annelies De Paepe and colleagues from Ghent
University find that ?The Arabidopsis mutant eer2 has enhanced ethylene
responses in the light.? September 2005.

They describe a new member of the class of enhanced ethylene response
mutants, which may aid scientists in understanding the process of
development and senescence in plants. Their research is published in the
latest issue of the Journal of Experimental Botany. Using ethylene
treatments on Arabidopsis plants, as well as studies of plant RNA,
chlorophyll levels, and gene linkage, researchers found that the mutant
phenotype is hypersensitive to ethylene applications. It does not senesce
faster than the wild type, and can grow even on a low nutrient medium.
