The granule size distribution of starch strongly influences its physicochemical properties and the functionality of wheat. Twelve wheat cultivars grown in east China’s Huanghuai region were used for investigating the granule size distribution, amylose content, and their interrelationship. The results showed that the volume distribution of starch granules show the typical bimodal with peak values in the ranges of 4.44–5.36 µm and 21.7–23.82 µm, respectively. Surface area distribution of granules was also bimodal with peak values in the ranges of 2.53–3.06 µm and 19.8–21.7 µm, respectively. The limits between the two populations both occurred at 10 µm. A typical population of number distribution of granules with peak values in the range of 0.52–0.67 µm. Proportions of granules <2.6 µm, 2.6–10 µm, and 10–40 µm were in the range of 10.06–13.63%, 28.54–41.6%, and 45.4–61.3% of total volume, respectively. Proportions of granules <10 µm were in the range of 99.9% of the total number. The amylose content was significant and negatively correlated to volume percentage of granule <10 µm, and significant and positively correlated to the volume percentage of granule 22–40 µm.

Abstract In Triticeae endosperm (e.g. wheat and barley), starch granules have a bimodal size distribution (with A- and B-type granules) whereas in other grasses the endosperm contains starch granules with a unimodal size distribution. Here, we identify the gene, BGC1 (B-GRANULE CONTENT 1), responsible for B-type starch granule content in Aegilops and wheat. Orthologues of this gene are known to influence starch synthesis in diploids such as rice, Arabidopsis, and barley. However, using polyploid Triticeae species, we uncovered a more complex biological role for BGC1 in starch granule initiation: BGC1 represses the initiation of A-granules in early grain development but promotes the initiation of B-granules in mid grain development. We provide evidence that the influence of BGC1 on starch synthesis is dose dependent and show that three very different starch phenotypes are conditioned by the gene dose of BGC1 in polyploid wheat: normal bimodal starch granule morphology; A-granules with few or no B-granules; or polymorphous starch with few normal A- or B-granules. We conclude from this work that BGC1 participates in controlling B-type starch granule initiation in Triticeae endosperm and that its precise effect on granule size and number varies with gene dose and stage of development.
