The phototropins are flavoprotein kinases that control phototropic bending, light-induced chloroplast movement, and stomatal opening in plants. Two flavin mononucleotide binding light, oxygen, or voltage (LOV) domains are the sites for initial photochemistry in these blue light photoreceptors. We...
Recombinants isolated from most meiotic intragenic recombination experiments in maize, but not in yeast, are borne principally on crossover chromosomes. This excess of crossovers is not explained readily by the canonical double-strand break repair model of recombination, proposed to account for a...
The signal transduction pathways that control cytokinesis in plants are largely uncharacterized. Here, we provide genetic evidence that mitogen-activated protein kinase kinase kinases (MAPKKKs) play a role in the control of plant cell division. Using a reverse-genetic approach, we isolated plants...
