TLDG readings

The theme for the 2015 Thursday Lunch Discussion Group (TLDG) is Interesting papers by upcoming seminar speakers. Discussing the seminar speaker's papers together beforehand will strengthen our seminar experience, offering a chance for deeper conversations with the speaker when they arrive and giving us background to more fully understand the implications of the speaker's work and seminar. On weeks without a seminar speaker, other topical papers will be chosen for discussion. Links to or pdfs of each week's paper will be posted here.

The group meets in the OEB Seminar Room (319 MOR 2) on Thursdays from 12 noon - 1 p.m. Lunch is provided.

Thursday, February 26
Seminar: Friday, February 27 • Evolutionary genetics of plant reproductive form and phenology
Jill Preston, Department of Plant Biology, University of Vermont
Host: Madelaine Bartlett
TLDG Reading:
Preston et al, (2011) Reduce, Reuse and Recycle: Developmental evolution of trait diversification. American Journal of Botany 98(3): 397–403.

Jill Preston’s research focuses on understanding the internal developmental
and genetic constraints that work in shaping the evolution of plant form
and function. Specifically she focuses on increasing our understanding of
how plant reproductive development evolves with these constraints.\

Her current research focuses on three main areas of interest: understanding
the genetic basis for shifts in growth habit of eudicots between annuality
and perenniality, looking at how grasses have evolved various mechanisms to
deal with cold temperate zones, and elucidating the genetic basis for the
origin of fused petals in the clade Asteridae.

The following paper gives a broad overview into the conservation of genes
and genetic pathways in the continuing evolution of developmental
patterning in angiosperm evolution.
