Lettuce (Lactuca sativa), cultivated mainly for its edible leaves and stems, is an important vegetable crop worldwide. Genomes of cultivated lettuce (L. sativa cv. Salinas) and its wild relative L. serriola accession US96UC23 are sequenced, but a clear understanding of the genetic basis for divergence in phenotypes of the two species is lacking. Tandem mass tag (TMT) based mass spectrometry is used to quantitatively compare protein levels between these two species. Four-day old seedlings is transplanted into 500 mL pots filled with soil. Plants are grown for 8 weeks under 250 µmol m-2 sec-1 continuous light, 20 °C and relative humidity between 50-70%. Leaf discs (1 cm diameter) from three individuals per biological replicate are analyzed. A total of 3000 proteins are identified, of which the levels of 650 are significantly different between 'Salinas' and US96UC23. Pathway analysis indicated a higher flux of carbon in 'Salinas' than US96UC23. Many essential metabolic pathways such as tetrapyrrole metabolism and fatty acid biosynthesis are upregulated in 'Salinas' compared with US96UC23. This study provides a reference proteome for researchers interested in understanding lettuce biology and improving traits for cultivation.
