DNA polymorphism at the cytosolic phosphoglucose isomerase (PgiC) locus of the wild plant Arabidopsis thaliana.

Numai utilizatorii înregistrați pot traduce articole

DNA variation in a 4.7-kb region of the cytosolic phosphoglucose isomerase (PgiC) locus was investigated for 21 ecotypes of Arabidopsis thaliana. The estimated nucleotide diversity was 0.0038, which was one-third of those in previously investigated loci. Since most of the nucleotide variations (93%)

Molecular characterization of duplicate cytosolic phosphoglucose isomerase genes in Clarkia and comparison to the single gene in Arabidopsis.

The nucleotide sequence of PgiC1-a which encodes a cytosolic isozymes of phosphoglucose isomerase (PGIC; EC 5.3.1.9) in Clarkia lewisii, a wildflower native to California, is described and compared to the previously published sequence of the duplicate PgiC2-a from the same genome. Both genes have

Defects in leaf carbohydrate metabolism compromise acclimation to high light and lead to a high chlorophyll fluorescence phenotype in Arabidopsis thaliana.

BACKGROUND We have studied the impact of carbohydrate-starvation on the acclimation response to high light using Arabidopsis thaliana double mutants strongly impaired in the day- and night path of photoassimilate export from the chloroplast. A complete knock-out mutant of the triose

Plastidial Phosphoglucose Isomerase Is an Important Determinant of Seed Yield through Its Involvement in Gibberellin-Mediated Reproductive Development and Storage Reserve Biosynthesis in Arabidopsis.

Numai utilizatorii înregistrați pot traduce articole

The plastid-localized phosphoglucose isomerase isoform PGI1 is an important determinant of growth in Arabidopsis thaliana, likely due to its involvement in the biosynthesis of plastidial isoprenoid-derived hormones. Here, we investigated whether PGI1 also influences seed yields. PGI1 is strongly

Arabidopsis Responds to Alternaria alternata Volatiles by Triggering Plastid Phosphoglucose Isomerase-Independent Mechanisms.

Numai utilizatorii înregistrați pot traduce articole

Volatile compounds (VCs) emitted by phylogenetically diverse microorganisms (including plant pathogens and microbes that do not normally interact mutualistically with plants) promote photosynthesis, growth, and the accumulation of high levels of starch in leaves through cytokinin (CK)-regulated

The role of plastidial glucose-6-phosphate/phosphate translocators in vegetative tissues of Arabidopsis thaliana mutants impaired in starch biosynthesis.

Numai utilizatorii înregistrați pot traduce articole

Arabidopsis thaliana mutants impaired in starch biosynthesis due to defects in either ADP glucose pyrophosphorylase (adg1-1), plastidic phosphoglucose mutase (pgm) or a new allele of plastidic phosphoglucose isomerase (pgi1-2) exhibit substantial activity of glucose-6-phosphate (Glc6P) transport in

Starch synthesis in Arabidopsis is achieved by spatial cotranscription of core starch metabolism genes.

Numai utilizatorii înregistrați pot traduce articole

Starch synthesis and degradation require the participation of many enzymes, occur in both photosynthetic and nonphotosynthetic tissues, and are subject to environmental and developmental regulation. We examine the distribution of starch in vegetative tissues of Arabidopsis (Arabidopsis thaliana) and

The 5' leader of plant PgiC has an intron: the leader shows both the loss and maintenance of constraints compared with introns and exons in the coding region.

Numai utilizatorii înregistrați pot traduce articole

PgiC, a complex gene with 23 coding exons and 22 intervening introns, encodes the cytosolic isozyme of phosphoglucose isomerase (EC 5.3.1.9) in higher plants. Here, we report RNA ligase-mediated rapid amplification of cDNA ends experiments that showed that PgiC in Clarkia (Onagraceae) and

Genome-Wide Association Mapping Reveals That Specific and Pleiotropic Regulatory Mechanisms Fine-Tune Central Metabolism and Growth in Arabidopsis.

Numai utilizatorii înregistrați pot traduce articole

Central metabolism is a coordinated network that is regulated at multiple levels by resource availability and by environmental and developmental cues. Its genetic architecture has been investigated by mapping metabolite quantitative trait loci (QTL). A more direct approach is to identify enzyme

SUGAR-DEPENDENT6 encodes a mitochondrial flavin adenine dinucleotide-dependent glycerol-3-p dehydrogenase, which is required for glycerol catabolism and post germinative seedling growth in Arabidopsis.

Numai utilizatorii înregistrați pot traduce articole

The aim of this study was to clone and characterize the SUGAR-DEPENDENT6 (SDP6) gene, which is essential for postgerminative growth in Arabidopsis (Arabidopsis thaliana). Mutant alleles of sdp6 were able to break down triacylglycerol following seed germination but failed to accumulate soluble

Starch Biosynthesis in Guard Cells But Not in Mesophyll Cells Is Involved in CO2-Induced Stomatal Closing.

Numai utilizatorii înregistrați pot traduce articole

Starch metabolism is involved in stomatal movement regulation. However, it remains unknown whether starch-deficient mutants affect CO2-induced stomatal closing and whether starch biosynthesis in guard cells and/or mesophyll cells is rate limiting for high CO2-induced stomatal closing. Stomatal
