BACKGROUND Transcriptome sequencing analysis is a powerful tool in molecular genetics and evolutionary biology. Here we report the results of de novo 454 sequencing, characterization, and comparison of inflorescence transcriptomes of two closely related dogwood species, Cornus canadensis and C. florida (Cornaceae). Our goals were to build a preliminary(More)
The response of woody plant tissues to freezing temperature has evolved into two distinct behaviors: an avoidance strategy, in which intracellular water supercools, and a freeze-tolerance strategy, where cells tolerate the loss of water to extracellular ice. Although both strategies involve extracellular ice formation, supercooling cells are thought to(More)
Genome size variation is of fundamental biological importance and has been a longstanding puzzle in evolutionary biology. Several hypotheses for genome size evolution including neutral, maladaptive, and adaptive models have been proposed, but the relative importance of these models remains controversial. Primulina is a genus that is highly diversified in(More)
Two TFL1 -like genes, CorfloTFL1 and CorcanTFL1 cloned from Cornus florida and C. canadensis, function in regulating the transition to reproductive development in Arabidopsis. TERMINAL FLOWER 1 (TFL1) is known to regulate inflorescence development in Arabidopsis thaliana and to inhibit the transition from a vegetative to reproductive phase within the shoot(More)
