Fourteen cultivars of cherry tomatoes and four high-pigment tomato hybrids were cultivated in southern Italy, the red-ripe fruits analyzed for their content different classes antioxidants antioxidant activity. Among cultivars, significant differences found between lycopene, β-carotene, α-tocopherol, vitamin C (ascorbic acid dehydroascorbic acid), total phenolic flavonoid contents. LS203 Corbus appear to be with highest lipophilic hydrophilic among tomatoes, respectively. All showed an...
Many fruits, including watermelon, are proficient in carotenoid accumulation during ripening. While most genes encoding steps the biosynthetic pathway have been cloned, few transcriptional regulators of these defined to date. Here we describe identification a set putative carotenoid-related transcription factors resulting from fresh watermelon and transcriptome analysis fruit development Our goal is both clarify expression profiles identify candidate molecular targets for crop...
A protein fraction [precipitate obtained between 40 and 65% (NH4)2SO4 satn.] prepared from cambial cells, differentiating xylem cells differentiated of pine fir trees contained all the enzymes required for nucleoside diphosphate sugar interconversions. By using UDP-D-[U-14C]glucose or UDP-D-[U-14C]galactose, UDP-D-[U-14C-]glucuronic acid UDP-D-[U-14C]xylose as substrates, activities UDP-D-galactose 4-epimerase (DC 5.1.3.2), UDP-D-xylose 4-epimerase(EC 5.1.3.5), UDP-D-glucose dehydrogenase...
The secretory pathway in plants involves sustained traffic to the cell wall, as matrix components, polysaccharides and proteins reach wall through endomembrane system. We studied secretion pattern of cell-wall tobacco protoplasts leaf epidermal cells using fluorescent forms a pectin methylesterase inhibitor protein (PMEI1) polygalacturonase (PGIP2). two most representative fusions, secGFP-PMEI1 PGIP2-GFP, reached by passing ER Golgi stacks but distinct mechanisms. was linked...
BACKGROUND: Lycopene is used for several industrial applications. Supercritical CO2 (SC-CO2) extraction from red-ripe tomato fruits an excellent technique to replace the use of harmful solvents. In this study, starting tomatoes ordinary and high-lycopene cultivars, effect different agronomical technical aspects on lycopene content, stability yield was evaluated throughout production process fresh final SC-CO2-extracted oleoresin containing lycopene. RESULTS: Red-ripe cultivars differed in...
Explants of pith parenchyma excised from Romaine lettuce heads (Lactuca sativa Linn. var. Romàna) exhibited xylogenesis after four days dark incubation on a Murashige and Skoog (1962) medium containing auxin (IAA, NAA, or 2,4‐D), cytokinin (zeatin, kinetin, benzyladenine), sucrose, agar. With the exception 2,4‐D, required both an exogenous auxir cytokinin. The greatest numbers tracheids were produced by IAA (5.0 mg/liter)‐zeati (0.1 mg/liter) 2,4‐D (0.07 mg/liter)‐zeatin treatments, whereas...
This study provides information about the carbohydrate present in tomato pomace (skins, seeds, and vascular tissues) as well byproducts of lycopene supercritical carbon dioxide extraction (SC-CO₂) such serum exhausted matrix reports their conversion into bioethanol. The pomace, constituting approximately 4% fruit fresh weight, SC-CO₂-exhausted were enzyme saccharified with 0.1% Driselase leading to sugar yields ~383 ~301 mg/g dw, respectively. Aliquots hydrolysates (80% sauce fw) fermented...
The regulatory functions of Rab proteins in membrane trafficking lie their ability to perform as molecular switches that oscillate between a GTP- and GDP-bound conformation. role tomato LeRab11a secretion was analyzed tobacco protoplasts. Green fluorescent protein (GFP)/red (RFP)-tagged localized at the trans-Golgi network (TGN) vivo. Two serines GTP-binding site were mutagenized, giving rise three mutants Rab11S22N, Rab11S27N Rab11S22/27N. double mutation reduced marker protein, secRGUS...
We report the hydrophilic and lipophilic antioxidant activities, as well total phenol, flavonoid, tocochromanol (tocopherol tocotrienol), carotenoid contents in edible portion of wild cultivated varieties chicory ( Cichorium intybus L.) basal rosette leaves species poppy Papaver rhoeas L.), known by natives “paparina,” collected countryside Salento (South Apulia, Italy). analyzed (1) two cultivars chicory, “Catalogna” harvested area between S. Pietro Vernotico Tuturano (Brindisi) “Otrantina”...
Heat and drought stress have emerged as major constraints for durum wheat production. In the Mediterranean area, their negative effect on crop productivity is expected to be exacerbated by occurring climate change. Xyloglucan endotransglucosylase/hydrolases (XTHs) are chief enzymes in cell wall remodelling, whose relevance expansion morphogenesis suggests a central role responses. this work potential of XTHs abiotic tolerance was investigated wheat. The separate effects dehydration heat...
