- Bulley S, Rassam M, Hoser D, Otto W, Schünemann N, Wright M, et al. Gene expression studies in kiwifruit and gene over-expression in Arabidopsis indicates that GDP-L-galactose guanyltransferase is a major control point of vitamin C biosynthesis. J Exp Bot. 2009;60:765-78 pubmed publisher..These studies show the importance of GDP-L-galactose guanyltransferase as a rate-limiting step to AsA, and demonstrate how AsA can be significantly increased in plants...
- Yao J, Tomes S, Xu J, Gleave A. How microRNA172 affects fruit growth in different species is dependent on fruit type. Plant Signal Behav. 2016;11:e1156833 pubmed publisher..These results further indicate that the influence of miR172 on fruit growth in different plant species depends on its fruit type. ..
- Hamiaux C, Drummond R, Janssen B, Ledger S, Cooney J, Newcomb R, et al. DAD2 is an ?/? hydrolase likely to be involved in the perception of the plant branching hormone, strigolactone. Curr Biol. 2012;22:2032-6 pubmed publisher..These observations suggest that DAD2 acts to bind the mobile strigolactone signal and then interacts with PhMAX2A during catalysis to initiate an SCF-mediated signal transduction pathway...
- Ledger S, Janssen B, Karunairetnam S, Wang T, Snowden K. Modified CAROTENOID CLEAVAGE DIOXYGENASE8 expression correlates with altered branching in kiwifruit (Actinidia chinensis). New Phytol. 2010;188:803-13 pubmed publisher..The CCD pathway for control of branch development is conserved across a wide range of species, including kiwifruit, a woody perennial. ..
- Lin Wang K, Bolitho K, Grafton K, Kortstee A, Karunairetnam S, McGhie T, et al. An R2R3 MYB transcription factor associated with regulation of the anthocyanin biosynthetic pathway in Rosaceae. BMC Plant Biol. 2010;10:50 pubmed publisher..In order to further understand tissue-specific anthocyanin regulation we have isolated orthologous MYB genes from all the commercially important rosaceous species...
- Laing W, Wright M, Cooney J, Bulley S. The missing step of the L-galactose pathway of ascorbate biosynthesis in plants, an L-galactose guanyltransferase, increases leaf ascorbate content. Proc Natl Acad Sci U S A. 2007;104:9534-9 pubmed..Transient expression of this A. chinensis gene in tobacco leaves resulted in a >3-fold increase in leaf ascorbate as well as a 50-fold increase in GDP-L-galactose-D-mannose-1-phosphate guanyltransferase activity...
- Newcomb R, Crowhurst R, Gleave A, Rikkerink E, Allan A, Beuning L, et al. Analyses of expressed sequence tags from apple. Plant Physiol. 2006;141:147-66 pubmed..This resource paves the way for a concerted functional genomics effort in this important temperate fruit crop. ..
- Strabala T, O donnell P, Smit A, Ampomah Dwamena C, Martin E, Netzler N, et al. Gain-of-function phenotypes of many CLAVATA3/ESR genes, including four new family members, correlate with tandem variations in the conserved CLAVATA3/ESR domain. Plant Physiol. 2006;140:1331-44 pubmed..Similarities among overexpression phenotypes of many CLE genes correlate with similarities in their CLE domain sequences, suggesting that the CLE domain is responsible for interaction with cognate receptors. ..
- Laing W, Bulley S, Wright M, Cooney J, Jensen D, Barraclough D, et al. A highly specific L-galactose-1-phosphate phosphatase on the path to ascorbate biosynthesis. Proc Natl Acad Sci U S A. 2004;101:16976-81 pubmed..The data are discussed in terms of the pathway to ascorbate biosynthesis in plants...
- Davies L, Harris P. Atomic force microscopy of microfibrils in primary cell walls. Planta. 2003;217:283-9 pubmed..The microfibrils in the extracted cell walls of A. thaliana were significantly narrower (3.2+/-0.13 nm) than those in untreated walls. The results are consistent with the microfibrils containing only one cellulose crystallite...
- Ampomah Dwamena C, Morris B, Sutherland P, Veit B, Yao J. Down-regulation of TM29, a tomato SEPALLATA homolog, causes parthenocarpic fruit development and floral reversion. Plant Physiol. 2002;130:605-17 pubmed..Based on the temporal and spatial expression pattern and transgenic phenotypes, we propose that TM29 functions in floral organ development, fruit development, and maintenance of floral meristem identity in tomato. ..
- Ledger S, Strayer C, Ashton F, Kay S, Putterill J. Analysis of the function of two circadian-regulated CONSTANS-LIKE genes. Plant J. 2001;26:15-22 pubmed..Experiments with the highest COL1 over-expressing line indicate that its circadian defects are fluence rate-dependent, suggesting an effect on a light input pathway(s). ..
