Cell-wall carbohydrates and their modification as a resource for biofuels.
Plant cell walls represent the most abundant renewable resource on this planet. Despite their great abundance, only 2% of this resource is currently used by humans. Hence, research into theExpand
Identification of Protein Transport Complexes in the Chloroplastic Envelope Membranes via Chemical Cross-Linking
TLDR
It is proposed that each envelope membrane contains distinct translocation complexes and that a portion of these interact to form contact sites even in the absence of precursor proteins. Expand
Stable association of chloroplastic precursors with protein translocation complexes that contain proteins from both envelope membranes and a stromal Hsp100 molecular chaperone
TLDR
Stable interactions between precursor proteins and their associated membrane translocation components in detergent‐solubilized chloroplastic membrane fractions are identified and possible roles for stromal Hsp100 in protein import and mechanisms of precursor binding in chloroplasts are discussed. Expand
Envelope membrane proteins that interact with chloroplastic precursor proteins.
TLDR
It is proposed that prSSU first binds in an ATP-independent fashion to the 86-kD protein, and the energy-requiring step is association with the 75- kD protein and assembly of a translocation contact site between the inner and outer membrane of the chloroplastic envelope. Expand
Disrupting Two Arabidopsis thaliana Xylosyltransferase Genes Results in Plants Deficient in Xyloglucan, a Major Primary Cell Wall Component[W][OA]
TLDR
It is concluded that XXT1 and XXT2 encode xylosyltransferases that are required for xyloglucan biosynthesis in vivo and this results in significant changes in the mechanical properties of these plants. Expand
Genes Galore: A Summary of Methods for Accessing Results from Large-Scale Partial Sequencing of Anonymous Arabidopsis cDNA Clones
TLDR
The more than 13,400 plant ESTs that are currently available provide a new resource that will facilitate progress in many areas of plant biology and are illustrated by a description of the results obtained from analysis of 1500 Arabidopsis ESTs from a cDNA library prepared from equal portions of poly(A+) mRNA from etiolated seedlings, roots, leaves, and flowering inflorescence. Expand
Tic40, a membrane‐anchored co‐chaperone homolog in the chloroplast protein translocon
TLDR
It is proposed that Tic40 functions as a co‐chaperone in the stromal chaperone complex that facilitates protein translocation across the inner membrane. Expand
The mur2 mutant of Arabidopsis thaliana lacks fucosylated xyloglucan because of a lesion in fucosyltransferase AtFUT1
TLDR
The normal growth habit and wall strength of mur2 plants casts doubt on hypotheses regarding roles of xyloglucan fucosylation in facilitating xylglucan–cellulose interactions or in modulating growth regulator activity. Expand
Protein Import and Routing Systems of Chloroplasts
Plastids are ubiquitous plant cell organelles that perform many essential functions. Chloroplasts are the most complex type of plastid, both structurally and functionally, containing six distinctExpand
Protein import into chloroplasts.
TLDR
Homologs of some transport components have been identified in cyanobacteria suggesting that at least some of import machinery was inherited from the cyanobacterial ancestors that gave rise to chloroplasts. Expand
