TLDR
This Tansley insight evaluates the current literature on starch metabolism in response to abiotic stresses, and discusses the key enzymes involved and how they are regulated.Abstract:
Contents 943 I. 943 II. 944 III. 945 IV. 945 V. 948 VI. 949 950 References 950 SUMMARY: Abiotic stresses, such as drought, high salinity and extreme temperatures, pose one of the most important constraints to plant growth and productivity in many regions of the world. A number of investigations have shown that plants, including several important crops, remobilize their starch reserve to release energy, sugars and derived metabolites to help mitigate the stress. This is an essential process for plant fitness with important implications for plant productivity under challenging environmental conditions. In this Tansley insight, we evaluate the current literature on starch metabolism in response to abiotic stresses, and discuss the key enzymes involved and how they are regulated.read more

Dynamic changes in the starch-sugar interconversion within plant source and sink tissues promote a better abiotic stress response.
Shaoyun Dong,Diane M. Beckles +1 more
TL;DR: A model explains how starch-sugar interconversion can be a convergent point for regulating carbon use in stress tolerance at the whole-plant level and explains how localized starch degradation into sugars is vital to the plant cold stress response.

Biochar: A Sustainable Approach for Improving Plant Growth and Soil Properties
TL;DR: In this paper, the properties of biochar, its interaction with soil microflora, and its role in plant growth promotion when added to the soil are discussed. But, it has been widely documented in previous studies that, the crop growth and yield can be increased by using biochar.

Circadian control of carbohydrate availability for growth in Arabidopsis plants at night
TL;DR: Starch degradation is under circadian control to ensure that carbohydrate availability is maintained until the next anticipated dawn, and this control is necessary for maintaining plant productivity.
