Sweet sorghum as biofuel feedstock: recent advances and available resources
TLDR
Various attributes of sweet sorghum that make it an ideal candidate for biofuel feedstock are discussed, and an overview of genetic diversity, tools, and resources available for engineering and/or marker-assisting breeding of sweet Sorghum are provided.Abstract:
Sweet sorghum is a promising target for biofuel production. It is a C4 crop with low input requirements and accumulates high levels of sugars in its stalks. However, large-scale planting on marginal lands would require improved varieties with optimized biofuel-related traits and tolerance to biotic and abiotic stresses. Considering this, many studies have been carried out to generate genetic and genomic resources for sweet sorghum. In this review, we discuss various attributes of sweet sorghum that make it an ideal candidate for biofuel feedstock, and provide an overview of genetic diversity, tools, and resources available for engineering and/or marker-assisting breeding of sweet sorghum. Finally, the progress made so far, in identification of genes/quantitative trait loci (QTLs) important for agronomic traits and ongoing molecular breeding efforts to generate improved varieties, has been discussed.read more

TL;DR: The semi-arid regions of the world are spread over 48 countries on four continents and cover a total area of nearly 20 million square kilometres about 500 million people live there Modern technology has only lightly touched the farmer of the semiarid tropics He uses little fertiliser; the soils he tills are often eroded and depleted of nutrients The power he uses almost always is animal or human.

TL;DR: The accumulation of triacylglycerol in sorghum leaf tissues to levels between 3 and 8.4% on a dry weight basis depending on leaf and plant developmental stage is reported, a first step forward towards the development of sorghums as a dedicated biomass oil crop.

TL;DR: The results imply that selection for Dry gene mutations was a major step leading to the origin of sweet sorghum, and fine-tuning its regulatory network could provide a molecular tool to control crop stem texture.
Are sucrose transporter expression profiles linked with patterns of biomass partitioning in Sorghum phenotypes? | NOVA. The University of Newcastle's Digital Repository
TL;DR: Sorghum bicolor is a genetically diverse C4 monocotyledonous species, encompassing varieties capable of producing high grain yields as well as sweet types which accumulate soluble sugars (predominantly sucrose) within their stems to high concentrations.

Sugar partitioning and source-sink interaction are key determinants of leaf senescence in maize.
TL;DR: In this paper, the authors analyzed senescence induced by the lack of grain sink in maize, termed source-sink regulated Senescence (SSRS), and compared the associated physiological and metabolic changes with those accompanying natural senescences, and demonstrated a crucial role of sugar partitioning, signalling and utilization in SSRS.

Rapid phosphatidic acid accumulation in response to low temperature stress in Arabidopsis is generated through diacylglycerol kinase
TL;DR: Evidence is provided that the rapid 32P-PtdOH response was primarily generated through DAG kinase (DGK), and a tentative model illustrating direct cold effects on phospholipid metabolism is presented.
