-
CaSUS1 expression is barely detectable in young flower buds and leaves. Transcripts of this isoform are observed in old flower buds and roots, and accumulates to a high level in stems

at 3 d and 10 d after flowering, SUS protein localized to the silique wall, seed coat, funiculus, and endosperm. By 13 d after flowering, SUS protein is detected in the embryo and aleurone layer, but is absent from the seed coat and funiculus
-
at 3 d and 10 d after flowering, SUS protein localized to the silique wall, seed coat, funiculus, and endosperm. By 13 d after flowering, SUS protein is detected in the embryo and aleurone layer, but is absent from the seed coat and funiculus. Within the silique wall, SUS localizes specifically to the companion cells, indicating that SUS activity may be required to provide energy for phloem transport activities in the silique wall
additional information
isoform SuSy1 is expressed exclusively in phloem companion cells
isoform SuSy4 is expressed exclusively in phloem companion cells
-
developing, sucrose synthase reaches a maximum about 500 to 600 growing degree days after flowering, when cell numbers were no longer increasing, but the cotyledons are increasing rapidly in dry weight
-

-
mRNA levels of CaSUS2 is undetectable in young endosperm, but increased towards the ripening of endosperm tissues
-
CaSUS1 expression is barely detectable in young flower buds and leaves. Transcripts of this isoform are observed in old flower buds and roots, and accumulates to a high level in stems
-
CaSUS2 expression is low in flower buds and in flowers whether young or mature
-
CaSUS1 mRNAs accumulats mainly during the early development of perisperm and endosperm, as well as during pericarp growing phases
-
CaSUS2 transcript levels is maximal at later stages of pericarp (205234 day after flowering) and endosperm (234 day after flowering) development. Weak CaSUS2 expression is observed in the early stages (60 and 89 day after flowering) of perisperm development, as well as at 176 day after flowering
-
very low enzyme activity in young and unripe muskmelons, but rapid accumulation of sucrose during ripening
-
SuSy activity increases dramatically during fruit maturation, while activity is low at the young fruit developmental stage, still lower at the endocarp hardening stage
in green fruit, isoform Sus4 is expressed at nearly 200fold lower levels than isoform Sus3. Elevated level of expression in ripening fruit for isoform Sus3
in green fruit, isoform Sus4 is expressed at nearly 200fold lower levels than sioform Sus3
enzymic activity is higher in immature internodes than in mature internodes in all cultivars, sucrose synthase transcript expression shows a similar pattern. Sucrose synthase activity is negatively correlated with sucrose and positively correlated with hexose sugars
-
level can differ significantly in different parts of the internodes and with maturity. Both vascular and storage parenchyma tissue contain SuSy in young and mature internodes
-
SUS1 is the predominant isoform of SUS associated with microsomes isolated from the base of the maize leaf elongation zone and from kernels at 20 and 30 days after pollination. SUS2 exists predominantly as a hetero-oligomer with SUS1 in kernels
isozyme expresssion patterns during development differ from each other

-
high expression of Msus1 mRNA in expanding leaves, not detectable in expanding leaves
-
2 genotypes ICPL 84023 and ICP 301 tolerant to waterlogging stress, and 2 genotypes ICP 7035 and Pusa 207 susceptible to waterlogging stress. Pattern of variation in reducing sugar content in the 4 genotypes is parallel to sucrose synthase activity. ICPL 84023 and ICP 301 also show fewer declines in total and non-reducing sugars and greater increase in reducing sugar and SuSy activity than ICP 7035 and Pusa 207
-
high CaSUS2 gene expression is observed in light-exposed leaves (positioned at the terminal ending of the branch). CaSUS2 mRNA levels is moderate in shaded leaves (collected inside the plant)
-
low expression enzyme level in young leaves, moderate levels in old leaves
-
elongation zone, isoenzyme SUS2. SUS2 exists predominantly as a hetero-oligomer with SUS1 in kernels
-
SUS1 is the predominant isoform of SUS associated with microsomes isolated from the base of the maize leaf elongation zone and from kernels at 20 and 30 days after pollination
-
light and metabolic signals control the selective degradation of sucrose synthase in maize leaves during deetiolation. SUS degradation is important to supply residues for the synthesis of other proteins required for autotrophic metabolism
-
mRNA levels of CaSUS2 is barely detectable in young pericarp, but increased towards the ripening of pericarp tissues
-
activity of sucrose synthase and the content of starch in the xylem and phloem of the two birch varieties, 40-year-old trees, and 8-year-old trees of Betula carelica, overview
-
SuSy is specifically localized in the creous walled sieve element of the phloem
-
sucrose synthase has a role in the construction of the extracellular matrix and thus in the morphogenesis of pollen tubes. Distribution of Sus is affected by brefeldin A and depended on the nutrition status of the pollen tube, because an absence of metabolic sugars in the growth medium caused Sus to distribute differently during tube elongation
-
it is supposed that the sucrose synthase activity in sugar-beet roots is controlled by sucrose synthesized in leaves rather than by phytohormones
-
activities of sucrose synthase is not significantly higher in wounded roots than in unwounded controls at any time during 13 days of postwounding storage
-
SBSS1 transcript levels are elevated in wounded, anoxic and cold-treated roots. SBSS1 protein levels exhibit little change in stressed roots, even after 7 d. SBSS1 expression in response to wounding, anoxia and cold may be regulated by post-transcriptional mechanisms
-
SBSS2 transcript levels are elevated in wounded, anoxic and cold-treated roots. SBSS2 protein levels exhibit little change in stressed roots, even after 7 d. SBSS2 expression in response to wounding, anoxia and cold may be regulated by post-transcriptional mechanisms

-
an 80% to 90% reduction of MtSucS1 proteins in roots and root nodules specifically limit plant growth and organ development under nodulation-dependent conditions, leading to marked changes in expression of genes involved in the nodule C and N metabolism and consequently to a reduced performance of amino acid biosynthesis
isoform sus4 is expressed at nearly 200fold lower levels than sioform Sus3
-
increased activity is in the tip region and in the stele of root axes. Increased in situ activity correlates with cell wall thickening by cellulose deposition under hypoxia

sucrose synthase is one of the central enzymes in sucrose cleavage in root nodules. SuSy2 is the second most abundant isoform present in Medicago truncatula root nodules

at 3 d and 10 d after flowering, SUS protein localized to the silique wall, seed coat, funiculus, and endosperm. By 13 day after flowering, SUS protein is detected in the embryo and aleurone layer, but is absent from the seed coat and funiculus. Co-localization of SUS protein and starch grains in the seed coat at 3 and 10 day after flowering indicates that SUS may be involved in temporary starch deposition during the early stages of seed development
