Potato starch synthases: Functions and relationships

Biochemistry and Biophysics Reports, 2017
Starch, a very compact form of glucose units, is the most abundant form of storage polyglucan in nature. The starch synthesis pathway is among the central biochemical pathways, however, our understanding of this important pathway regarding genetic elements controlling this pathway, is still insufficient.

Distinct Functions of STARCH SYNTHASE 4 Domains in Starch Granule Formation [PDF]

Plant Physiology, 2017
The formation of normal starch granules in Arabidopsis (Arabidopsis thaliana) leaf chloroplasts requires STARCH SYNTHASE 4 (SS4). In plants lacking SS4, chloroplasts typically produce only one round granule rather than multiple lenticular granules. The mechanisms by which SS4 determines granule number and morphology are not understood.

In vivo phosphoproteome characterization reveals key starch granule-binding phosphoproteins involved in wheat water-deficit response

BMC Plant Biology, 2017
Background Drought stress during grain development causes significant yield loss in cereal production. The phosphorylated modification of starch granule-binding proteins (SGBPs) is an important mechanism regulating wheat starch biosynthesis.

Solubilization of the Starch-Granule-Bound Starch Synthase of Normal Maize Kernels [PDF]

Plant Physiology, 1983
The starch-granule-bound starch synthase from Zea mays has been solubilized with a recovery of between 50 and 84%. Chromatography of the solubilized enzyme on DEAE-Sepharose resolves two fractions of activity which may be distinguished by their response to citrate. Neither solubilized isoenzyme displays any significant activity with UDPglucose.

Heat stress during grain filling affects activities of enzymes involved in grain protein and starch synthesis in waxy maize

Scientific Reports, 2018
High temperature (temperature over 35 °C) is an extremely important environmental factor that affects the maize grain quality in Southern China. The effects of heat stress after pollination on grain protein and starch deposition and activities of ...

Starch accumulation in hulless barley during grain filling

Botanical Studies, 2017
Background Starch consists of two types of molecules: amylose and amylopectin. The objective of this study was increase understanding about mechanisms related to starch accumulation in hulless barley (Hordeum vulgare L.) grain by measuring temporal ...

The Effects of Short-Term Exposure to Low Temperatures During the Booting Stage on Starch Synthesis and Yields in Wheat Grain

Frontiers in Plant Science, 2021
Low temperatures (LT) in spring can have a major impact on the yields of wheat in winter. Wheat varieties with different cold sensitivities (the cold-tolerant Yannong 19 variety and the cold-sensitive Yangmai 18 variety) were used to study the responses ...

It takes two to tango: a new partner in amylose synthesis.

PLoS Biology, 2015
The mechanism by which plants make starch-a vital foodstuff for billions of humans-is poorly understood, with a clear role for just one enzyme, granular binding starch synthase. A new study identifies a protein needed to recruit this enzyme to the starch
