A combination of localization studies and starch accumulation assays showed that SWEET9 is involved in sucrose efflux from the nectary parenchyma. (wikipedia.org)
Sucrose is synthesized in the cytosol and translocated to other non-photosynthetic tissues for direct metabolic use or for conversion to starch. (biomedcentral.com)
In the Light-independent or dark reactions the enzyme RuBisCO captures CO 2 from the atmosphere and in a process that requires the newly formed NADPH, called the Calvin-Benson cycle releases three-carbon sugars which are later combined to form sucrose and starch. (wikidoc.org)
Glucose4
The generalized reaction catalyzed by known proteins of this family is: sugars (in) ⇌ sugars (out) SWEETs were originally identified in Arabidopsis thaliana, in a screen for novel facilitators of transmembrane glucose transport. (wikipedia.org)
Those that mediate glucose transport include at least six out of seventeen sugar homologues in Arabidopsis (i.e. (wikipedia.org)
It can be used as an immediate food nutrient, or combined and rearranged to form monosaccharide sugars, such as glucose , which can be transported to other cells, or packaged for storage as insoluble polysaccharides such as starch . (wikidoc.org)
The 3 options were: phloem unloading, or uptake or efflux from nectary parenchyma. (wikipedia.org)
SWEET ( MtN3_saliva ) domain proteins, a recently identified group of efflux transporters, play an indispensable role in sugar efflux, phloem loading, plant-pathogen interaction and reproductive tissue development. (biomedcentral.com)
Metabolic2
The quantitative expression of starch metabolic genes revealed that eleven genes of JE0173 and twelve genes of JE0218 had consistent expression in high starch mutant lines. (bvsalud.org)
An additional two candidate genes showed over-expression (PHO1, PUL) in the high starch mutant lines, indicating that other starch metabolic genes may also contribute to the starch biosynthesis. (bvsalud.org)
[ 3 ] Pure, dry fructose is a very sweet, white, odorless, crystalline solid and is the most water-soluble of all the sugars. (en-academic.com)
Commercially, fructose is usually derived from sugar cane, sugar beets and corn and there are 3 commercially important forms. (en-academic.com)
Yield3
However, the yield of solvent decreased with the increased initial sugar concentration. (biomedcentral.com)
Introduction of functional alleles in the starch biosynthetic genes help in the improvement of the quality and yield of cereals. (bvsalud.org)
This work provides new insights for further understanding the functions of SUSs and candidate genes for improving yield, starch content, and abiotic stress tolerance in sweet potatoes. (bvsalud.org)
Carbon1
In addition to their essential roles as substrates in carbon and energy metabolism, sugars also play an important role in signal transduction [ 1 , 2 ]. (biomedcentral.com)
Fermentation1
This work demonstrated an effective approach of improved butanol fermentation and its probable mechanisms of this positive effect, i.e. the adsorption of ABE solvent and the adhesion of bacteria on porous substrate accounted for the production improvement and the proportional variation of solvent constituents. (biomedcentral.com)
Transporters2
The SWEET family (Sugars Will Eventually Be Exported Transporter), also known as the PQ-loop, Saliva or MtN3 family (TC# 2.A.123), is a family of sugar transporters and a member of the TOG superfamily. (wikipedia.org)
2010) reviewed evidence for a new class of sugar transporters, named SWEETs. (wikipedia.org)
Roles1
The IbSUSs especially IbSUS2, IbSUS5 and IbSUS7 might play vital roles in storage root development and starch biosynthesis. (bvsalud.org)
These simple sugars can combine with each other to form more complex types. (biologyonline.com)
The combination of two simple sugars is called a disaccharide . (biologyonline.com)
Content5
A homologue in petunias had been shown to have an inverse correlation between expression and starch content in nectaries. (wikipedia.org)
The starch content of the seed coat was higher than the wild-type, and the starch content of the embryo was lower than the wild-type. (wikipedia.org)
A megazyme kits were used for measuring the total starch content, resistant starch, amylose, and amylopectin content. (bvsalud.org)
These mutations can affect the other starch related genes and help to increase the starch content in this mutant line (JE0173). (bvsalud.org)
Most modern fruits and vegetables have been bred to have much higher sugar content than the wild plants they are descended from. (en-academic.com)
Found1
The proteins of the SWEET family have been found in plants, animals, protozoans, and bacteria. (wikipedia.org)
Plants1
It is a complex process occurring in higher plants , phytoplankton , algae , as well as bacteria such as cyanobacteria . (wikidoc.org)
Development1
Similarly, in low starch mutant lines, eleven genes of JE0089 and thirteen genes of JE0418 had consistent expression in all stages of seed development. (bvsalud.org)
Improvement1
CONCLUSIONS: This study screened a large scale of mutant population and identified mutants, could provide useful genetic resources for the study of starch biosynthesis and genetic improvement of wheat in the future. (bvsalud.org)
SWEET1
Proteins of the SWEET family appear to catalyze facilitated diffusion (entry or export) of sugars across the plant plasma membrane or the endoplasmic reticulum membrane. (wikipedia.org)
