Other claims from this paper (10)

Observation ARAD1 was expressed in all tissues, particularly vascular tissues of leaves and stems.
Intervention effect Mutant leaves had reduced arabinose content, to about 75% of wild-type levels.
Intervention effect Mutant stems had reduced arabinose content, to 46% of wild-type levels.
Observation Other pectic domains and glycoproteins did not change in the mutants.
Observation Mutant stem cellular structure was not altered.
Observation Rhamnogalacturonan I from mutant tissue had about 30% of wild-type arabinose.
Observation Residual arabinan in mutant tissue was structurally similar to wild type.
Intervention effect ARAD1 transformation fully complemented the mutant phenotype.
Observation No ARAD1 transformant exceeded wild-type arabinan levels.
Mechanism The authors suggest ARAD1 is an arabinan alpha-1,5-arabinosyltransferase.

Two Arabidopsis Threonine Aldolases Are Nonredundant and Compete with Threonine Deaminase for a Common Substrate Pool

Vijay Joshi; Karen M. Laubengayer; Nicolas Schauer; et al. The Plant Cell 2006. doi:10.1105/tpc.106.044958

Other claims from this paper (9)

Observation THA1 is expressed primarily in seeds and seedlings.
Observation THA2 is expressed in vascular tissue throughout the plant.
Observation tha1 mutants had more than a 50-fold increase in seed threonine content.
Observation tha1 mutants had few other significant metabolic changes.
Observation Homozygous tha2 mutations caused a lethal albino phenotype.
Intervention effect Feedback-insensitive Thr deaminase rescued tha2 mutants and tha1 tha2 double mutants.
Mechanism The rescue indicates THA1- and THA2-mediated glycine formation is dispensable.
Intervention effect Seed-specific feedback-insensitive Thr deaminase expression greatly increased seed Ile content in both aldolase mutants.
Mechanism The two threonine catabolic enzymes likely compete for a common substrate pool.

Other claims from this paper (5)

Intervention effect ZIS overexpression yielded 224-1000 ng g(-1) alpha-zingiberene in tomato fruit.
Intervention effect ZIS tomato fruit accumulated other sesquiterpenes absent from controls.
Intervention effect ZIS tomato fruit produced monoterpenes at 1-22 ng g(-1), versus absent or minute control concentrations.
Intervention effect ZIS-transgenic tomato vigor and shape matched wild type.
Mechanism Authors inferred that tomato cytosol contains an available geranyl diphosphate pool.
