Cereal yields decrease when grain fill proceeds under conditions of prolonged, moderately elevated temperatures. Endosperm-endogenous processes alter both rate and duration of dry weight gain, but underlying mechanisms remain unclear. Heat effects co

Enhanced stability of maize endosperm ADP-glucose pyrophosphorylase is gained through mutants that alter subunit interactions

Autor: Thomas W. Greene, L C Hannah

Publikováno v: Proceedings of the National Academy of Sciences. 95:13342-13347

Temperature lability of ADP-glucose pyrophosphorylase (AGP; glucose-1-phosphate adenylyltransferase; ADP: α- d -glucose-1-phosphate adenylyltransferase, EC 2.7.7.27 ), a key starch biosynthetic enzyme, may play a significant role in the heat-induced

Phosphorylation of Serine-15 of Maize Leaf Sucrose Synthase (Occurrence in Vivo and Possible Regulatory Significance)

Autor: P. C. Liao, Robert W. McMichael, Douglas A. Gage, Steven C. Huber, Karen E. Koch, Prem S. Chourey, L. C. Hannah, Joan L. Huber

Publikováno v: Plant Physiology. 112:793-802

Experiments were conducted to determine whether sucrose synthase (SuSy) was phosphorylated in the elongation zone of maize (Zea mays L.) leaves. The approximately 90-kD subunit of SuSy was 32P-labeled on seryl residue(s) when excised shoots were fed

A single mutation that increases maize seed weight

Publikováno v: Proceedings of the National Academy of Sciences. 93:5824-5829

The maize endosperm-specific gene shrunken2 (Sh2) encodes the large subunit of the heterotetrameric starch synthetic enzyme adenosine diphosphoglucose pyrophosphorylase (AGP; EC 2.7.7.27). Here we exploit an in vivo, site-specific mutagenesis system

Structural Features of the Maize sus1 Gene and Protein

Autor: John Baier, Janine R. Shaw, D. St Clair, Donald R. McCarty, L. C. Hannah, Robert J. Ferl, Christian B. Carson

Publikováno v: Plant Physiology. 106:1659-1665

Genomic clones, cDNA clones, and protein of the maize (Zea mays L.) Suc synthase1 (sus1) gene were isolated and sequenced. Termini (5[prime] and 3[prime]) of the transcribed unit were identified. The SUS1 protein was purified from tissue culture cell

Coordinated Transcriptional Regulation of Storage Product Genes in the Maize Endosperm

Autor: G. Feix, C. Boyer, L. C. Hannah, Michael J. Giroux

Publikováno v: Plant Physiology. 106:713-722

We have demonstrated that expression of genes involved in starch and storage protein synthesis of the maize (Zea mays L.) endosperm are coordinated. Genetic lesions altering synthetic events in one biosynthetic pathway affect expression of genes in b

ADP-glucose pyrophosphorylase in shrunken-2 and brittle-2 mutants of maize

Autor: L. C. Hannah, Michael J. Giroux

Publikováno v: Molecular and General Genetics MGG. 243:400-408

The Shrunken-2 (Sh2) and Brittle-2 (Bt2) genes of maize encode subunits of the tetrameric maize endosperm ADPglucose pyrophosphorylase. However, in all sh2 and bt2 mutants so far examined, measurable ADPglucose pyrophosphorylase activity remains. We

The Viviparous-1 gene and abscisic acid activate the C1 regulatory gene for anthocyanin biosynthesis during seed maturation in maize

Autor: Leonard Rosenkrans, Indra K. Vasil, Donald R. McCarty, Tsukaho Hattori, Vimla Vasil, L. C. Hannah

Publikováno v: Genes & Development. 6:609-618

The Viviparous-1 (Vp1) gene is required for expression of the C1 regulatory gene of the anthocyanin pathway in the developing maize seed. We show that VP1 overexpression and the hormone, abscisic acid (ABA), activate a reporter gene driven by the C1
