De novo RNA sequencing and analysis reveal the putative genes involved in diterpenoid biosynthesis in roots.

Unlabelled: In this study, the putative genes involved in diterpenoid alkaloids biosynthesis in roots were revealed by transcriptome sequencing. 59.39 GB of clean bases and 119,660 unigenes were assembled, of which 69,978 unigenes (58.

A Tetratricopeptide Repeat Protein Regulates Carotenoid Biosynthesis and Chromoplast Development in Monkeyflowers ().

Little is known about the factors regulating carotenoid biosynthesis in flowers. Here, we characterized the () locus from two monkeyflower () species, the bumblebee-pollinated species and the hummingbird-pollinated species We show that loss-of-function mutations of cause drastic down-regulation of the entire carotenoid biosynthetic pathway. The causal gene underlying encodes a tetratricopeptide repeat protein that is closely related to the Arabidopsis () REDUCED CHLOROPLAST COVERAGE proteins.

A dominant-negative actin mutation alters corolla tube width and pollinator visitation in Mimulus lewisii.

A third of all angiosperm species produce flowers with petals fused into a corolla tube. The various elaborations of corolla tube attributes, such as length, width and curvature, have enabled plants to exploit many specialized pollinator groups. These elaborations often differ dramatically among closely related species, contributing to pollinator shift and pollinator-mediated reproductive isolation and speciation.
