begin at the beginning: a bac-end view of the passion fruit (passiflora) genome.the passion fruit (passiflora edulis) is a tropical crop of economic importance both for juice production and consumption as fresh fruit. the juice is also used in concentrate blends that are consumed worldwide. however, very little is known about the genome of the species. therefore, improving our understanding of passion fruit genomics is essential and to some degree a pre-requisite if its genetic resources are to be used more efficiently. in this study, we have constructed a large-insert bac ...201425260959
mineral composition of pulp and production of the yellow passion fruit with organic and conventional fertilizers.the use of organic foods has been increased in the world. organic fertilizers, like cattle manure, have emerged as an important component of the organic system production. the production, mass, size, and mineral composition of passion fruit pulp were evaluated when treated with a mineral fertilizer (control) (min) or cattle manure at a single dose equivalent to potassium fertilizer (org) or double dose (2×org). the production and the numbers of fruits of plants treated with min and 2×org was hig ...201727664654

a light in the shadow: the use of lucifer yellow technique to demonstrate nectar reabsorption.nectar reabsorption is a widely known phenomenon, related to the strategy of resource-recovery and also to maintain the nectar homeostasis at the nectary. the method currently performed to demonstrate nectar being reabsorbed involves the use of radioactive tracers applied to the nectary. although this method works perfectly, it is complex and requires specific supplies and equipment. therefore, here we propose an efficient method to obtain a visual demonstration of nectar reabsorption, adapting ...201323783170
screening for new hydroxynitrilases from plants.we established a simple hplc method to determine the activity and stereochemistry of the chiral mandelonitrile synthesized from benzaldehyde and cyanide, and applied it to screen for hydroxynitrile lyase (hnl) activity of plant origin. a total of 163 species of plants among 74 families were examined for (r)- and (s)-hnl activities using the method. we discovered that homogenate of leaves of baliospermum montanum shows (s)-hnl activity, while leaves and seeds from passiflora edulis, and seeds fro ...200516377893
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
floral scent of brazilian passiflora: five species analised by dynamic headspace.this study describes for the first time the chemical composition and olfactive description of floral scent from brazilian passiflora (passiflora edulis sim, passiflora alata curtis, passiflora cincinnata mast., passiflora coccinea aubl. and passiflora quadrangularis l.). five species were grown in greenhouse at the agronomic institute (iac), são paulo, brazil. volatile compounds were collected using dynamic headspace. analyses of scent composition were performed by gas chromatograph coupled to m ...201627598839
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
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
histochemical analysis of seed reserve mobilization in passiflora edulis sims fo. flavicarpa o. deg. (yellow passion fruit) during 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
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
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
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
