TL;DR: It is reported here that previously described hy3 mutants have mutations in the gene coding for phytochrome B (PhyB), the first mutations shown to lie in a plant photoreceptor gene.

TL;DR: The Arabidopsis DET2 gene encodes a protein that shares significant sequence identity with mammalian steroid 5α-reductases, and brassinosteroids may constitute a distinct class of phytohormones with an important role in light-regulated development of higher plants.

TL;DR: Arf6 and arf8 single mutants and sesquimutants had delayed stamen development and decreased fecundity, indicating that ARF6 and ARF8 gene dosage affects timing of flower maturation quantitatively.

TL;DR: Arabidopsis lines carrying T-DNA insertions in AUXIN RESPONSE FACTOR1 (ARF1) and ARF2 genes are examined and it is found that ARF1 promotes transitions between multiple stages of Arabidopsis development, and an arf1 mutation increased transcription of Aux/IAA genes in Arabicidopsis flowers, supporting previous biochemical studies that indicated that ARFs are a transcriptional repressor.

TL;DR: The greening phenotypes produced by recessive mutations in a gene designated de-etiolated-2 (DET2) are described, implying that DET1 and DET2 function in distinct pathways that affect downstream light-regulated genes.
