<!-- <p>Research in the Rose lab broadly spans the structure, function and practical uses of plant cell walls. We have a long standing interest in cell wall metabolism as it relates to plant growth, development and interactions with pathogens, but additionally, cellulosic cell walls represent a central component of the biofuels industry, as well as providing the building blocks for a many plant-derived products.</p>

<p><strong>The plant cell wall proteome ("secretome"):</strong> We are applying high throughput genomics and proteomics techniques to identify and characterize novel cell wall proteins with currently unknown and unexploited functions. These strategies include both functional screens for, and computational prediction of, the genes encoding secreted proteins, as well as the isolation and structural characterization of extracellular proteins. Through an NSF Plant Genome Research grant, we are developing a more comprehensive catalog and functional inventory of the plant cell wall proteome, or "secretome" (<a href="http://solgenomics.net/secretom">http://solgenomics.net/secretom</a>), based on two principal experimental systems.</p>

<p><strong>Fruit Development and Ripening:</strong> Tomato fruit development provides an opportunity to study cell wall metabolism associated with both cell expansion and fruit softening. In addition to investigating the dynamics of the polysaccharide extracellular matrix we have several ongoing projects studying the importance of the cuticle, a highly specialized lipidic cell wall, to fruit physiology and quality traits.</p>
<p>The cuticle appears to have a critical, and yet poorly understood, influence on fruit texture, and plays an important role in regulating the rate of desiccation and tissue collapse, as well as limiting microbial infection. We have been developing tools to better understand the processes that underly cuticle synthesis, assembly and restructuring. These include a new 3D imaging technique, which has revealed several previously undescribed architectural features of the tomato fruit cuticle. We are now characterizing the composition and structural development of the cuticle in wild and domesticated tomato species, as well analyzing as a number of recently identified cuticle associated and long shelf-life mutants.</p>

<p><strong>Plant-Pathogen Interactions:</strong> The plant cell wall provides the first line of defense against microbial pathogens and the cocktails of proteins that are secreted into the plant apoplast by the host and pathogen play critical roles in the initiation and progression of infection. However, insights into the identity, function and regulation of these secreted protein populations ("secretomes") is still rudimentary, particularly in the case in the case of eukaryotic pathogens. To better understand the qualitative and quantitative changes in the cell wall proteome during pathogenesis, we have developed and applied a suite of analytical tools to study the tomato-<em>Phytophthora infestans</em> pathosystem, focusing particularly interested on the co-evolution of the host and pathogen secretomes. Our data provide evidence for a molecular arms race between suites of cell wall hydrolases, from plants and microbes, and cognate inhibitor proteins that are secreted by the other partner.</p>

<p><strong>Biofuels and Bioenergy Crops:</strong> The hemicellulose-cellulose matrix of plant walls provides a major source of carbon to the biofuel industry and demand for research in this area is increasing dramatically, given current concerns regarding energy security and global climate change. We are currently characterizing new families of wall-associated proteins and gaining a better understanding of plant wall dynamics, which is suggesting strategies to generate plants with enhanced potential as bioenergy crops. For example, plant glycosyl hydrolases (GHs) are thought to play a central role in many aspects of cell wall assembly, architectural remodeling and disassembly during cell growth and differentiation. However, given the structural diversity and large sizes of the GH families, the specific biological functions of relatively few genes have been characterized to date. In this regard, we have targeted several GH families that contain discrete divergent subclasses with a modular structure, and have focused on characterizing the biochemical and biological functions of representative isozymes from tomato and Arabidopsis.</p>
