Foolish Seedlings and DELLA Regulators

Foolish seedlings and DELLA regulators: the functions of rice SLR1 and Arabidopsis RGL1 in GA signal transduction.

As every student of plant biology learns, gibberellin (GA) was first isolated in Japan in the 1930s from a fungus that causes a serious disease in rice, called “foolish seedling disease” ( bakanae-byo ) by Japanese farmers. Afflicted plants were characterized by excessive growth of seedlings and a decline in seed production in mature plants. The purified active compound was named for the fungus...

The Pea DELLA proteins LA and CRY are important regulators of gibberellin synthesis and root growth.

The theory that bioactive gibberellins (GAs) act as inhibitors of inhibitors of plant growth was based originally on the slender pea (Pisum sativum) mutant (genotype la cry-s), but the molecular nature of this mutant has remained obscure. Here we show that the genes LA and CRY encode DELLA proteins, previously characterized in other species (Arabidopsis [Arabidopsis thaliana] and several grasse...

We describe a statistical technique for assigning senses to words. An instance of a word is assigned a sense by asking a question about the context in which the word appears. The question is constructed to have high mutual information with the translation of that instance in another language. When we incorporated this method of assigning senses into our statistical machine translation system, t...
