Experts and Doctors on starch in Switzerland
- Zanella M, Borghi G, Pirone C, Thalmann M, Pazmino D, Costa A, et al. Î²-amylase 1 (BAM1) degrades transitory starch to sustain proline biosynthesis during drought stress. J Exp Bot. 2016;67:1819-26 pubmed publisher..We propose the transitory-starch/proline interplay as an interesting trait to be tackled by breeding technologies aimingto improve drought tolerance in relevant crops. ..
- Endrulat T, Saurer M, Buchmann N, Brunner I. Incorporation and remobilization of ¹³C within the fine-root systems of individual Abies alba trees in a temperate coniferous stand. Tree Physiol. 2010;30:1515-27 pubmed publisher..Only then can one avoid dilution of the labelling signal by mistake, due to analysis of non-labelled non-target species roots...
- Stettler M, Eicke S, Mettler T, Messerli G, Hortensteiner S, Zeeman S. Blocking the metabolism of starch breakdown products in Arabidopsis leaves triggers chloroplast degradation. Mol Plant. 2009;2:1233-46 pubmed publisher..We propose that the accumulation of maltose and malto-oligosaccharides causes chloroplast dysfunction, which may by signaled via a form of retrograde signaling and trigger chloroplast degradation. ..
- Streb S, Delatte T, Umhang M, Eicke S, Schorderet M, Reinhardt D, et al. Starch granule biosynthesis in Arabidopsis is abolished by removal of all debranching enzymes but restored by the subsequent removal of an endoamylase. Plant Cell. 2008;20:3448-66 pubmed publisher..We propose that DBEs function in normal amylopectin synthesis by promoting amylopectin crystallization but conclude that they are not mandatory for starch granule synthesis. ..
- Delatte T, Umhang M, Trevisan M, Eicke S, Thorneycroft D, Smith S, et al. Evidence for distinct mechanisms of starch granule breakdown in plants. J Biol Chem. 2006;281:12050-9 pubmed..Consistent with this model, chloroplastic alpha-amylase AtAMY3, which could release soluble branched glucans, is induced in Atisa3 and in the Atisa3/Atlda double mutant. ..
- Delatte T, Trevisan M, Parker M, Zeeman S. Arabidopsis mutants Atisa1 and Atisa2 have identical phenotypes and lack the same multimeric isoamylase, which influences the branch point distribution of amylopectin during starch synthesis. Plant J. 2005;41:815-30 pubmed..We conclude that the AtISA1/AtISA2 isoamylase influences glucan branching pattern, but that this may not be the primary determinant of partitioning between crystalline starch and soluble phytoglycogen. ..
- Zeeman S, Thorneycroft D, Schupp N, Chapple A, Weck M, Dunstan H, et al. Plastidial alpha-glucan phosphorylase is not required for starch degradation in Arabidopsis leaves but has a role in the tolerance of abiotic stress. Plant Physiol. 2004;135:849-58 pubmed..We conclude that plastidial phosphorylase is not required for the degradation of starch, but that it plays a role in the capacity of the leaf lamina to endure a transient water deficit. ..
