 USA\n\nThe cultivated tomato (Solanum lycopersicum) is a tractable and eff
 icient model for fruit development\, storage quality and nutrient accumula
 tion\, in addition to being a crop of established and expanding production
 \, consumption and culinary importance the world over. Diverse\, well char
 acterized and freely available germplasm resources\, combined with efficie
 nt transformation and a high quality genome sequence have accelerated the 
 pace of tomato biology with practical implications to crop improvement. Ou
 r lab explores the function of ripening transcription factors underlying f
 ruit ripening mutations including those altered in the rin\, nor\, and u m
 utations defining fruit development roles for the MADS\, NAC and GLK trans
 cription factor families\, respectively.  Mining of these families provide
 d additional genes effecting fruit development and ripening characterized 
 in transgenic tomato plants.  Additional regulators have been uncovered vi
 a examination of fruit quality QTLs and genes associated with ripening bas
 ed on expression profiles. Genome enabled analysis of fruit development fu
 rther indicates that transcriptional control intersects with changes in th
 e epigenome.   Exploration of additional crop genomes suggests that some o
 f the regulators identified in tomato are conserved through evolution.  Di
 scoveries made through identification of genes underlying mutations and QT
 Ls\, combined with analyses of ripening phenomena as they permeate the mat
 uring fruit tissues\, reveal a complex developmental process regulated by 
 multiple factors with often conserved components that may serve as useful 
 targets for crop shelf-life and quality improvement across a diverse spect
 rum of important fruit crop species.\n
