Phytochromes are a family of plant photoreceptors that mediate physiological and developmental
responses to changes in red and far-red light conditions. In Arabidopsis, there are …

Plant responses to red and far-red light are mediated by a family of photoreceptors called
phytochromes. In Arabidopsis thaliana, there are genes encoding at least five phytochromes, …

In flowering plants, diploid sporophytic tissues in ovules and anthers support meiosis and
subsequent haploid gametophyte development. These analogous reproductive functions …

The plant hormone auxin controls many aspects of development and acts in part by inducing
expression of various genes. Arabidopsis thaliana semidominant shy2 (short hypocotyl) …

Phytochrome, a red/far-red-light photoreceptor protein of plants, is encoded by a small gene
family. Phytochrome A (PHYA), the product of the PHYA gene, is the predominant molecular …

In Arabidopsis, SHY2 encodes IAA3, a member of the auxin-induced Aux/IAA family. Gain-of-function
mutations in SHY2/IAA3 cause enlarged cotyledons, short hypocotyls, and altered …

Pollination in flowering plants requires that anthers release pollen when the gynoecium is
competent to support fertilization. We show that in Arabidopsis thaliana, two paralogous auxin …

In plants, both endogenous mechanisms and environmental signals regulate developmental
transitions such as seed germination, induction of flowering,leaf senescence and shedding …

Auxin induces various distinct developmental responses, partly by regulating gene expression.
The Aux/IAA genes are a large gene family, many of which are induced by auxin. Work …

The dominant gain-of-function axr2-1 mutation of Arabidopsis causes agravitropic root and
shoot growth, a short hypocotyl and stem, and auxin-resistant root growth. We have cloned …
