This study identifies Pho1a as the key glucosyltransferase for starch granule initiation in potato tubers, showing that its knockout leads to abnormal granule morphology and size.

This paper creates giant starch granules in wheat by modifying amyloplast size and granule initiation, resulting in starch with altered physicochemical properties.

The paper identifies two redundant MFP1 paralogs in wheat that interact with BGC1 and affect B-type granule initiation in endosperm amyloplasts.

This study identifies TaNF-YC10 as a key transcription factor regulating starch biosynthesis in wheat endosperm, showing its role in enhancing starch accumulation and grain weight.

This study characterizes tuber and starch properties in diploid potato lines and their hybrids, showing variation in starch structure and yield traits.

The paper uses live-cell imaging to show that simple-type starch granules in Brachypodium distachyon arise from multiple amyloplast initiations, challenging the one granule, one amyloplast model.

The paper investigates the role of LESV and ESV1 in starch initiation in potato tubers using CRISPR/Cas9 knockout and shows that LESV deficiency reduces granule diameter and mimics isa1/isa2 mutants.

This study shows that mutations at the TtMRC-A1 locus in durum wheat can alter starch granule size distributions, affecting pasting properties and grain quality.

The paper develops a curve fitting method using Python to analyze starch granule size distributions in cereals, finding that mixed distributions best describe wheat and barley, while unimodal distributions apply to maize and rice.

This study identifies the TaNF-Y-PRC2 complex as a regulator of starch and protein synthesis in wheat endosperm, revealing its role in epigenetic control through histone modification and gene repression.

This study shows that SAGA1 and SAGA2 proteins in Arabidopsis chloroplasts promote the formation of starch structures around proto-pyrenoids, contributing to CO2-concentrating mechanisms.
