Transcontinental patterns in floral pigment frequencies among animal-pollinated species Open
Flower coloration arises primarily from pigments that serve dual functions: attracting pollinators and mitigating environmental stresses. Among major flower pigment groups, anthocyanins and UV-absorbing phenylpropanoids are particularly no…

Can a flower color ancestral polymorphism transcend speciation? Open
Polymorphisms are common in nature, but they are rarely shared among closely related species. They could originate through convergence, ancestral polymorphism, or introgression. Although shared neutral genomic variation is commonplace, ver…

Proteomic analysis of microtubule inner proteins (MIPs) in Rib72 null <i>Tetrahymena</i> cells reveals functional MIPs Open
We performed a proteomic screen of cilia missing known microtubule inner proteins (MIPs) Rib72A and Rib72B to determine additional MIP candidates. One of these candidates, Fap115, was confirmed to be a structural and functional MIP using c…

Painting the green canvas: how pigments produce flower colours Open
Flowering plants are characterized by the production of striking flower colours and these colours are primarily caused by the accumulation of pigments in cells of the floral organs. The extraordinary array of colours displayed in flowers r…

Interpreting nature’s finest insect silks (Order Embioptera): hydropathy, interrupted repetitive motifs, and fiber-to-film transformation for two neotropical species Open
Silks produced by webspinners (Order Embioptera) interact with water by transforming from fiber to film, which then becomes slippery and capable of shedding water. We chose to explore this mechanism by analyzing and comparing the silk prot…

Changes at a Critical Branchpoint in the Anthocyanin Biosynthetic Pathway Underlie the Blue to Orange Flower Color Transition in Lysimachia arvensis Open
Anthocyanins are the primary pigments contributing to the variety of flower colors among angiosperms and are considered essential for survival and reproduction. Anthocyanins are members of the flavonoids, a broader class of secondary metab…
