Natural polyploidy inVanilla planifolia(Orchidaceae) [PDF]
Genome, 2008 Vanilla planifolia accessions cultivated in Reunion Island display important phenotypic variation, but little genetic diversity is demonstrated by AFLP and SSR markers. This study, based on analyses of flow cytometry data, Feulgen microdensitometry data, chromosome counts, and stomatal length measurements, was performed to determine whether polyploidy ...

Advances in Somatic Embryogenesis in Vanilla (Vanilla planifolia Jacks.)
2022Somatic embryogenesis is an in vitro plant morphogenetic process due to cell totipotentiality to induce shoot regeneration. To induce this proliferation pathway, we used auxins such as 2,4-dichlorophenoxyacetic acid in combination with cytokinins. There are numerous somatic embryogenesis protocols for a great diversity of plants, including orchids, but

Microencapsulation of vanilla (Vanilla planifolia Andrews) and powder characterization
Powder Technology, 2018Abstract Natural vanilla extract (NVE) and synthetic vanilla extract (SVE) were microencapsulated by spray-drying, using whey protein concentrate (WPC) as wall material. Physicochemical properties, volatility profile, vanillin concentration and antioxidant activity were evaluated by measuring total polyphenols, the inhibition of radical scavenging ...

Micropropagation and In Vitro Conservation of Vanilla (Vanilla planifolia Andrews)
2009Vanilla (Vanilla planifolia Andrews (syn. V. fragrans Salisb.), a source of natural vanillin, plays a major positive role in the economy of several countries. A native to the Central America, its primary gene pool is threatened by deforestation and over collection that has resulted in disappearance of natural habitats and wild species.

Identification of Novel Orosensory Active Molecules in Cured Vanilla Beans (Vanilla planifolia)
Journal of Agricultural and Food Chemistry, 2009Sequential application of solvent extraction, gel permeation chromatography, and HPLC in combination with taste dilution analyses, followed by LC-MS and 1D/2D NMR experiments, led to the discovery of seven velvety mouth-coating molecules in cured beans of Vanilla planifolia . Among these, 5-(4-hydroxybenzyl)vanillin, 4-(4-hydroxybenzyl)-2-methoxyphenol,

Purification and Characterization of Vanilla Bean (Vanilla planifolia Andrews) β-
Journal of Agricultural and Food Chemistry, 2003 Vanilla bean beta-D-glucosidase was purified to apparent homogeneity by successive anion exchange, hydrophobic interaction, and size-exclusion chromatography. The enzyme is a tetramer (201 kDa) made up of four identical subunits (50 kDa). The optimum pH was 6.5, and the optimum temperature was 40 degrees C at pH 7.0.

Hyperhydricity-Related Morphologic and Biochemical Changes in Vanilla (Vanilla planifolia)
Journal of Plant Growth Regulation, 2009Shoot cultures of vanilla (Vanilla planifolia) showed a progressive change toward hyperhydricity syn- drome (HHS) leading to the necrosis of shoot buds when transferred to liquid medium of shake-flask type from solid (gelled) medium (S). HHS was also associated with severe damage at cellular and subcellular levels, an increase in free polyamines (PAs ...

Protocols for Biotechnological Interventions in Improvement of Vanilla (Vanilla planifolia Andrews.)
2016Vanilla (Vanilla planifolia Andrews (syn. V. fragrans Salisb.), a native of Central America, is the primary source of natural vanillin and plays a major role in the global economy. The gene pool of vanilla is threatened by deforestation and overcollection that has resulted in disappearance of natural habitats and wild species.
