Reconstructing the evolutionary history of paralogous APETALA1/FRUITFULL-like genes in grasses (Poaceae).

Gene duplication is an important mechanism for the generation of evolutionary novelty. Paralogous genes that are not silenced may evolve new functions (neofunctionalization) that will alter the… (More)

Discrete developmental roles for temperate cereal grass VERNALIZATION1/FRUITFULL-like genes in flowering competency and the transition to flowering.

Jill C Preston, Elizabeth A. Kellogg
Plant physiology
2008

Members of the grass subfamily Pooideae are characterized by their adaptation to cool temperate climates. Vernalization is the process whereby flowering is accelerated in response to a prolonged… (More)

Parallel evolution of TCP and B-class genes in Commelinaceae flower bilateral symmetry

Flower bilateral symmetry (zygomorphy) has evolved multiple times independently across angiosperms and is correlated with increased pollinator specialization and speciation rates. Functional and… (More)

Adaptation to seasonality and the winter freeze

Jill C Preston, Simen R Sandve
Front. Plant Sci.
2013

Flowering plants initially diversified during the Mesozoic era at least 140 million years ago in regions of the world where temperate seasonal environments were not encountered. Since then several… (More)

Gradual disintegration of the floral symmetry gene network is implicated in the evolution of a wind-pollination syndrome.

Jill C Preston, Ciera C Martinez, Lena C. Hileman
Proceedings of the National Academy of Sciences…
2011

Angiosperms exhibit staggering diversity in floral form, and evolution of floral morphology is often correlated with changes in pollination syndrome. The showy, bilaterally symmetrical flowers of the… (More)

MADS-box gene expression and implications for developmental origins of the grass spikelet.

Jill C Preston, Ashley A. Christensen, Simon T. Malcomber, Elizabeth A. Kellogg
American journal of botany
2009

Basic questions regarding the origin and evolution of grass (Poaceae) inflorescence morphology remain unresolved, including the developmental genetic basis for evolution of the highly derived outer… (More)

Developmental genetics of floral symmetry evolution.

Jill C Preston, Lena C. Hileman
Trends in plant science
2009

The relative importance of convergence and parallelism in the independent evolution of similar traits remains an important question in evolutionary biology. Floral zygomorphy has evolved multiple… (More)

Conservation and divergence of APETALA1/FRUITFULL-like gene function in grasses: evidence from gene expression analyses.

Jill C Preston, Elizabeth A. Kellogg
The Plant journal : for cell and molecular…
2007

Duplicated APETALA1/FRUITFULL (AP1/FUL) genes show distinct but overlapping patterns of expression within rice (Oryza sativa) and within ryegrass (Lolium temulentum), suggesting discrete functional… (More)

Functional Evolution in the Plant SQUAMOSA-PROMOTER BINDING PROTEIN-LIKE (SPL) Gene Family

Jill C Preston, Lena C. Hileman
Front. Plant Sci.
2013

The SQUAMOSA-PROMOTER BINDING PROTEIN-LIKE (SPL) family of transcription factors is functionally diverse, controlling a number of fundamental aspects of plant growth and development, including… (More)

Conservation and diversification of the symmetry developmental program among close relatives of snapdragon with divergent floral morphologies.

Jill C Preston, Matthew A. Kost, Lena C. Hileman
The New phytologist
2009

Multiple evolutionary shifts in floral symmetry and stamen number have occurred in the snapdragon (Antirrhinum majus) family Veronicaceae. In Mohavea, Veronica and Gratiola there have been… (More)
