Starch is the main storage carbohydrate in plants and an important natural resource for food, feed industrial raw materials. However, details regarding pathway starch biosynthesis diversity of biosynthetic enzymes involved this process are poorly understood. This study uses a comprehensive phylogenetic analysis 74 sequenced plant genomes to revisit evolutionary history genes encoding ADP-glucose pyrophosphorylase (AGPase), synthase (SS), branching enzyme (SBE) de-branching (DBE)....

The effect of salt concentration on swelling power, rheological properties and saltiness perception waxy, normal high amylose maize starch was investigated. power decreased with increasing from 0% to 2.0% among all samples. Waxy showed the highest at different levels, while least power. addition increased gelatinization temperature waxy 71.3 °C 77.1 72.3 78.2 °C. Their storage modulus (G'), loss (G''), viscosity values lower were greater than those higher concentration. tan δ against...

The endosperm is a major organ of the seed that plays vital roles in determining weight and quality. However, genome-wide transcriptome patterns throughout maize development have not been comprehensively investigated to date. Accordingly, we performed high-throughput RNA sequencing (RNA-seq) analysis at 5, 10, 15 20 days after pollination (DAP). We found more than 11,000 protein-coding genes underwent alternative splicing (AS) events during four developmental stages studied. These were...

Plant-specific VQ proteins have crucial functions in the regulation of plant growth and development, as well abiotic stress responses. Their roles been established model Arabidopsis thaliana ; however, potato not adequately investigated. The protein core region contains a short FxxhVQxhTG amino acid motif sequence. In this study, VQ31 from was cloned functionally characterized. complete open reading frame (ORF) size StVQ31 is 672 bp, encoding 223 acids. Subcellular localization analysis...

Storage starch in starchy seed influences the weight and texture, determines its applications food nonfood industries. Starch granules from different plant sources have significantly shapes sizes, even more difference exists regions of same tissue. Therefore, it is very important to situ investigate morphology distribution whole seed. However, a simple rapid method deficient prepare section for investigating seeds large number samples. A was established seed, especially floury this study....

Increasing grain yield is a primary objective of maize breeding. Dissecting the genetic architecture furthers improvements to increase yield. Presented here an association panel composed 126 inbreds (AM126), which were genotyped by genotyping-by-sequencing (tGBS) method. We performed characterization and analysis related in panel. In total, 46,046 SNPs with minor allele frequency (MAF) ≥0.01 used assess diversity kinship AM126. The results showed that average MAF polymorphism information...

Abstract Particle‐size distribution, granular structure, and composition significantly affect the physicochemical properties, rheological nutritional function of starch. Flow cytometry flow sorting are widely considered convenient efficient ways classifying separating natural biological particles or other substances into subpopulations, respectively, based on differential response each component to stimulation by a light beam; results allow for correlation analysis parameters. In this study,...

Isocitrate dehydrogenase (IDH) is a key rate-limiting enzyme in the tricarboxylic acid cycle and acts glutamine synthesis. IDH also participates plant growth development response to abiotic stresses. We identified 11 maize genes (ZmIDH) classified these into ZmNAD-IDH ZmNADP-IDH groups based on their different coenzymes (NAD+ or NADP+). The group was further divided two subgroups according catalytic non-catalytic subunits, as Arabidopsis. ZmIDHs significantly differed physicochemical...
