cellular and molecular changes associated with competence acquisition during passion fruit somatic embryogenesis: ultrastructural characterization and analysis of serk gene expression.the integration of cellular and molecular data is essential for understanding the mechanisms involved in the acquisition of competence by plant somatic cells and the cytological changes that underlie this process. in the present study, we investigated the dynamics and fate of passiflora edulis sims cotyledon explants that were committed to somatic embryogenesis by characterizing the associated ultrastructural events and analysing the expression of a putative p. edulis ortholog of the somatic emb ...201626008651
evaluation of the antihypertensive properties of yellow passion fruit pulp (passiflora edulis sims f. flavicarpa deg.) in spontaneously hypertensive rats.various species of the genus passiflora have been extensively used in traditional medicine as sedatives, anxiolytics, diuretics and analgesics. in the present study, after the identification and quantification of phytochemical compounds from yellow passion fruit pulp by liquid chromatography-photodiode array-mass spectrometry (hplc-pda-ms/ms), its antihypertensive effect was investigated on spontaneously hypertensive rats. additionally, the renal function, evaluated by kidney/body weight, serum ...201423436457
nectar protein content and attractiveness to aedes aegypti and culex pipiens in plants with nectar/insect associations.we chose five easily propagated garden plants previously shown to be attractive to mosquitoes, ants or other insects and tested them for attractiveness to culex pipiens and aedes aegypti. long term imbibition was tested by survival on each plant species. both mosquito species survived best on impatiens walleriana, the common garden impatiens, followed by asclepias curassavica, campsis radicans and passiflora edulis, which sponsored survival as well as the 10% sucrose control. immediate preferenc ...201525792420
defense response in non-genomic model species: methyl jasmonate exposure reveals the passion fruit leaves' ability to assemble a cocktail of functionally diversified kunitz-type trypsin inhibitors and recruit two of them against papain.multiplicity of protease inhibitors induced by predators may increase the understanding of a plant's intelligent behavior toward environmental challenges. information about defense mechanisms of non-genomic model plant passion fruit (passiflora edulis sims) in response to predator attack is still limited. here, via biochemical approaches, we showed its flexibility to build-up a broad repertoire of potent kunitz-type trypsin inhibitors (ktis) in response to methyl jasmonate. seven inhibitors (20- ...201424849173

plant regeneration from protoplast cultures of passiflora edulis var. flavicarpa deg., p. amethystina mikan. and p. cincinnata mast.protoplasts isolated from seedling cotyledons of yellow passionfruit (passiflora edulis var. flavicarpa deg.) and two related wild species, p. amethystina mikan. and p. cincinnata mast., divided in culture and produced calli. shoot regeneration was obtained in ms medium (murashige and skoog 1962) containing 2.0 mg/l 6-benzylaminopurine (bap). regenerated plants produced roots in half-strength hormone-free ms medium and could be transferred to soil after being acclimatized.199324196297
biophysical characteristics of successful oilseed embryo cryoprotection and cryopreservation using vacuum infiltration vitrification: an innovation in plant cell preservation.heterogeneity in morphology, physiology and cellular chemistry of plant tissues can compromise successful cryoprotection and cryopreservation. cryoprotection is a function of exposure time × temperature × permeability for the chosen protectant and diffusion pathway length, as determined by specimen geometry, to provide sufficient dehydration whilst avoiding excessive chemical toxicity. we have developed an innovative method of vacuum infiltration vitrification (viv) at 381 mm (15 in) hg (50 kpa) ...201424788797
current trends of tropical fruit waste utilization.recent rapid growth of the world's population has increased food demands. this phenomenon poses a great challenge for food manufacturers in maximizing the existing food or plant resources. nowadays, the recovery of health benefit bioactive compounds from fruit wastes is a research trend not only to help minimize the waste burden, but also to meet the intensive demand from the public for phenolic compounds which are believed to have protective effects against chronic diseases. this review is focu ...201627246698
evolutionary, genetic, environmental and hormonal-induced plasticity in the fate of organs arising from axillary meristems in passiflora spp.tendrils can be found in different plant species. in legumes such as pea, tendrils are modified leaves produced by the vegetative meristem but in the grape vine, a same meristem is used to either form a tendril or an inflorescence. passiflora species originated in ecosystems in which there is dense vegetation and competition for light. thus climbing on other plants in order to reach regions with higher light using tendrils is an adaptive advantage. in passiflora species, after a juvenile phase, ...201322659398
effects of compounds from passiflora edulis sims f. flavicarpa juice on blood coagulation and on proteolytic enzymes.passion fruit (passiflora edulis sims f. flavicarpa) is popularly known for its sedative and calming properties and is consumed as a fresh fruit or as a juice. the clinical observation of blood incoagulability associated with excessive consumption of passion fruit juice, in a patient treated with warfarin, prompted the current study to investigate in vitro the presence of blood clotting inhibitors in passiflora edulis sims f. flavicarpa extract. after purification process, two compounds of disti ...201222486645
expression patterns of passiflora edulis apetala1/fruitfull homologues shed light onto tendril and corona identities.passiflora (passionflowers) makes an excellent model for studying plant evolutionary development. they are mostly perennial climbers that display axillary tendrils, which are believed to be modifications of the inflorescence. passionflowers are also recognized by their unique flower features, such as the extra whorls of floral organs composed of corona filaments and membranes enclosing the nectary. although some work on passiflora organ ontogeny has been done, the developmental identity of both ...201728174623
comparison of coefficients and distance measurements in passion fruit plants based on molecular markers and physicochemical descriptors.we investigated seven distance measures and 14 similarity coefficients in a set of observations of variables of the 'yellow' passion fruit plant (passiflora edulis sims), submitted to multivariate analyses (distance, projection and grouping). fourteen genotypes were characterized, based on dna amplification with 16 random amplified polymorphic dna primers and the assessment of nine fruit physical-chemical descriptors. the distance measurements and the similarity coefficients were compared by the ...200919731209
histochemical analysis of seed reserve mobilization in passiflora edulis sims fo. flavicarpa o. deg. (yellow passion fruit) during germination.in the present work, we analyzed the histochemical aspects of passiflora edulis seeds reserve mobilization during the first ten days of germination. our results showed that mainly lipids present in the endosperm are used as a reserve source, and their levels reduce at the same time the radicle protrudes, between the fourth and sixth day of sowing. furthermore, protein bodies are present in the cotyledons, which are degraded as germination occurs and are almost depleted by the time of radicle pro ...201121881794
removal of methylene blue dye from aqueous solutions by adsorption using yellow passion fruit peel as adsorbent.the removal of color from aquatic systems caused by presence of synthetic dyes is extremely important from the environmental viewpoint because most of these dyes are toxic, mutagenic and carcinogenic. in this present study, the yellow passion fruit (passiflora edulis sims. f. flavicarpa degener) peel a powdered solid waste, was tested as an alternative low-cost adsorbent for the removal of a basic dye, methylene blue (mb), from aqueous solutions. adsorption of mb onto this natural adsorbent was ...200817692516
