5 Tomato has long served as model system for fleshy fruit development,
6 and is an excellent system to study cell wall proteins as it is
7 associated with dramatic changes in wall biology, including
8 enzyme-mediated cell wall polysaccharide degradation, apoplastic sugar
9 metabolism and extracellular defenses against microbial
10 pathogens. However, there are few published proteomic analyses of
11 ripening tomato fruit and most of those are based on extraction of
12 total proteins followed by 2-DE separation, and the wall proteome was
13 not the major target. Consequently, the protein extraction step was
14 not optimized for secreted proteins.

23 Tomato leaves infected by <span class="species_binomial">P. infestans</span>.
29 Similarly, defense responses against pathogens are also fundamentally
30 associated with changes in the expression of secreted apoplastic
31 proteins, but there have been few systematic studies at the proteome
36 We have been developing methods to obtain sample materials highly
37 enriched in apoplast/cell wall proteins, including vacuum
38 dehydration, centrifugal dehydration and several methods that
39 involve the centrifugal isolation of the cell wall followed by
40 sequential extraction with solutions of increasing ionic
41 strength. Taken together, the goal is to create a more comprehensive
42 catalog of the tomato cell wall proteome, focusing on fruit and
43 leaves at various stages of infection by the oomycete Phytophthora
44 infestans. This will include both protein identification and
45 quantitative data, to gain insights into the dynamic properties of
46 the tomato secretome. Additionally we have been profiling "total
47 proteomes"; and screening the resulting protein populations for those
48 known to be localized in the cell wall with a predicted secretory
49 signal peptide, or that are <a href="/secretom/detail/glycoproteome">glycosylated</a>.
53 We have been applying several approaches for comparative proteomic
54 analysis, including Difference Gel Electrophoresis (DIGE), isobaric
55 Tag Relative Absolute Protein Quantitation (iTRAQ), exponentially
56 modified protein abundance index (emPAI) and MSE. The latter two
57 approaches were found to provide accurate relative quantitation data
58 on par with that provided by iTRAQ at significantly reduced cost,
59 but without the ability to multiplex. They have been integrated into
60 our work flow and are used where appropriate. We have also developed
61 a high/low pH reverse phase-reverse phase (RP-RP) separation
62 protocol to fractionate peptides prior to MS analysis. This new
63 approach complements the traditional strong cation exchange (SCX) RP
64 strategy and the Offgel peptide IEF fractionation.

70 Qualitative and quantitative characterization of the tomato
71 proteome, focusing principally on tomato fruit development and
72 ripening, and tomato leaves at different stages of infection by
73 P. infestans. Additional targets include proteins that are
74 regulated by abiotic stresses.

118 Wild type ripe tomato fruit (left), and equivalent stage fruit
119 from the nor (middle) and rin (right) mutants.
125 We are profiling the cell wall proteome of ripening tomato fruit,
126 contrasting those of wild type (cv. Ailsa Craig) and several
127 ripening impaired mutants: ripening inhibitor (rin), non-ripening
128 (Nor) and never ripe (Nr). While the genes responsible for all these
129 mutations have been cloned, and important progress has been made in
130 elucidating their respective signaling pathways, numerous aspects
131 remain poorly understood and the degree of regulatory complexity and
132 the multiplicity of underlying molecular mechanisms have far
133 exceeded expectations.
