deletion of extracellular invertase reduces Metarhizium robertsii growth on sucrose and rhizospheric exudates but enhances root colonization

-
metabolism
-
the isoforms EINV1, EINV2, EINV3 and EINV4 have the same molecular mass and catalytic properties such as Km for sucrose, pH optimum and temperature optimum, but they exhibit significant difference in pI values, thermal stability and chemical reactivity. The observed differences between isoforms arise from posttranslational modifications

isoforms VINV1 plays an important role in sucrose unloading and starch accumulation, as well in buffering the pools of sucrose, hexoses and sugar phosphates in leaves, specifically at later stages of plant development

isoforms VINV2 plays an important role in sucrose unloading and starch accumulation, as well in buffering the pools of sucrose, hexoses and sugar phosphates in leaves, specifically at later stages of plant development
physiological function
-
ectopic overexpression of invertase inhibitor INVINH1 in Arabidopsis thaliana specifically reduces cell wall invertase activity. By contrast, silencing its expression in tomato significantly increases the activity of cell wall invertase without altering activities of cytoplasmic and vacuolar invertases. Elevation of cell wall invertase activity in RNA interference transgenic tomato leads to a prolonged leaf life span involving in a blockage of abscisic acid-induced senescence and an increase in seed weight and fruit hexose level
physiological function
-
INV-E is associated with the development of the photosynthetic apparatus and the assimilation of nitrogen in Arabidopsis seedlings to control the ratio of sucrose content to hexose content
physiological function
-
loss-of-function mutation in cell wall invertase INCW2 gene Mn1 results in the miniature1 seed phenotype. In wild-type seed, walls in growth develop uniformly in the basal endosperm transfer cell layer during 7 to 17 d after pollination, and the secretory/endocytic organelles proliferate in the basal endosperm transfer cells. Mitochondria accumulate in the vicinity of walls in growth. In the mutant basal endosperm transfer cells, walls in growth are stunted and their endoplasmic reticulum is swollen, Golgi density in the mutant basal endosperm transfer cells is 51% of the wild-type Golgi density. However, the polarized distribution of mitochondria is not affected

role of LIN6 invertase during growth processes. In addition, LIN6 is regulated by a diurnal rhythm that drives LIN6 expression in subjective dawn
physiological function
-
single T-DNA insertion mutants of cytosolic isoforms cinv1 and cinv2 appear identical to wild-type plants on soil under our growth conditions. The cinv1/cinv2 double mutant plants flower and set seed when grown on soil, but are much smaller in all respects than wild-type plants at maturity. Seedlings of cinv1/cinv2 double mutant have relatively normal shoot growth, but drastically reduced root growth on solid medium without sugar. Whereas primary root extension over 7 days of growth is 60% of the wild-type value in cinv1 mutant, and 120% of the wild-type value in cinv2, it is only 17% of the wild-type value in cinv1/cinv2 double mutants. Cells in the root expansion zone of cinv1/cinv2 mutants are enlarged and have a greater tendency to collapse during manipulation than those of wild-type and single-mutant plants. Abnormal cell divisions occur in the stele, endodermis, and cortex. Growth on glucose restores root extension in double mutants to approximately half of wild-type. Neutral invertase activity in roots is 40% lower in double mutant than in wild-type seedlings
physiological function
Q8W413
T-DNA insertion lines of cell wall invertase 4 do not produce nectar. Overall nectary morphology appears to be normal, but mutant flowers accumulate higher than normal levels of starch in the receptacle, but not within the nectaries themselves. Conversely, wild-type, but not mutant, nectarial stomata stain intensely for starch. Cell wall extracts prepared from mutant flowers display greatly reduced invertase activity when compared with wild-type plants, and mutant flowers also accumulate significantly lower levels of total soluble sugar
physiological function
-
invertases are important for gall development in clubroot disease of Brassicaceae caused by Plasmodiophora brassicae. Different transgenic lines expressing an invertase inhibitor under the control of two root-specific promoters, Pyk10 and CrypticT80, which results in the reduction of invertase activity, show clearly reduced clubroot symptoms in root tissue with highest promoter expression, whereas hypocotyl galls develop normally

cell wall invertase is a central player in extrafloral nectar secretion
physiological function
-
cell wall invertase is a regulator in determining sequential development of endosperm and embryo through glucose signaling early in seed development
physiological function
-
extracellular invertase plays a pivotal role in rhizospheric interactions and root colonization
physiological function
-
high invertase activity of, and increased sucrose import into, young tomato fruit can contribute to their heat tolerance through increasing sink strength and sugar signalling activities, possibly regulating a programmed cell death pathway
physiological function
-
invertase plays an important role in regulating stomatal opening
physiological function
-
post-translational regulation of acid invertase by the vacuolar invertase inhibitor 2 is an important component of resistance to cold-induced sweetening
physiological function
-
the enzyme isoform CWIN1 plays a role in nuclear division but not cell wall biosynthesis in endosperm, as well as early seed development, particularly in regulating endosperm nuclear division, embryonic provascular formation, and transfer cell differentiation

hydrolysis of polyfructose moieties in agriculturally-sourced grass juice with recombinant truncated cytosolic enzyme results in the release of more than 13 mg/ml more bioavailable fructose than is measured in untreated grass juice. Bioethanol yields from fermentation experiments with Brewer's yeast and grass juice plus enzymeaere more than 25% higher than those achieved using untreated grass juice feedstock

alkaline invertase activity appears when the root begins to develop and simultaneously to synthesize sucrose - activity of enzyme form I is high during sucrose accumulation and the enzyme rapidly decreases when sucrose reaches a constant level, while the level of enzyme II activity is approximately constant, acid invertase activity is very high in immature roots, but rapidly decreases before sucrose is stored and is hardly detectable in mature roots

2.6 A crystal structure of cell-wall invertase 1 in complex with protein inhibitor, cell-wall inhibitor of beta-fructosidase, from tobacco. The structure recognizes a small amino acid motif in the inhibitor that directly targets the invertase active site. The activity of INV1 and its interaction with inhibitor are strictly pH-dependent with a maximum at about pH 4.5. At this pH, isothermal titration calorimetry reveals that the inhibitor tightly binds its target with nanomolar affinity

INVINH1
-
endogenous tomato invertase inhibitor. Ectopic overexpression of INVINH1 in Arabidopsis thaliana specifically reduces cell wall invertase activity. By contrast, silencing its expression in tomato significantly increases the activity of cell wall invertase without altering activities of cytoplasmic and vacuolar invertases. Elevation of cell wall invertase activity in RNA interference transgenic tomato leads to a prolonged leaf life span involving in a blockage of abscisic acid-induced senescence and an increase in seed weight and fruit hexose level

of seed. Separate growth of cotyledon types, Cot and Cot E based on a unique differential regeneration response, in vitro on Gamborg's B5 basal nutrient medium, 2% sucrose, and supplemented with N6-benzyladenine. Temporal differences in acid invertase enzyme activity are observed in differentiating explants. In general all N6-benzyladenine levels and both in the presence and/or absence of sucrose, acid invertase levels are lower in Cot than Cot E explants. A higher frequency of regeneration of Cot E explants is positively correlated with higher invertase activity. Invertase gene expression is highest in Cot explants at 12 and 15 days following culture

VIN activity in elongating fibers is approximately 4-6fold higher than that in leaves, stems, and roots. It is undetectable in fiberless cotton seed epidermis but becomes evident in initiating fibers and remains high during their fast elongation and drops when elongation slows. A genotype with faster fiber elongation has significantly higher fiber VIN activity and hexose levels than a slow-elongating genotype
