One wild species, Solanum pennellii, has low levels of pectate
lyase gene expression in the fruit.
Professor Seymour said: «We already have a line harboring a very small section of the S. pennellii genome with the alternative form of the pectate
lyase gene.
Natural variation exists in the levels of pectate
lyase gene expression in wild relatives of cultivated tomato and these can be used for conventional breeding purposes.
DNA sequence differences between the pectate
lyase genes from the cultivated tomato and S. pennellii can then be used as markers to screen the progeny from this cross.
Not exact matches
Professor Seymour and his team have identified a
gene that encodes a pectate
lyase which normally degrades the pectin in the tomato cell walls during ripening.
High levels of
gene expression were found in both strains for
genes involved in growth, energy and respiration (e.g., ribosomal proteins, ATP synthase, pseudoazurin), and the C - 1 metabolic carbon such as methanol dehydrogenase, ribulose monophosphate enzymes (D - arabino -3-hexulose 6 - phosphate formaldehyde -
lyase, 6 - phospho -3-hexuloisomerase), formaldehyde activating enzymes (Data S6, Fig.
