In vitro regeneration of cocona Solanum sessiliflorum , Solanaceae cultivars for commercial production. Cocona Solanum sessiliflorum Dunal is a solanaceous shrub native to the Amazon region that produces an edible fruit. This species has numerous advantages, particularly a high nutritional value and productivity.

However, due to irregular germination and rapid loss of seed viability, there are few plantations for production on a large scale. Development of alternative propagation strategies is essential for the production of homogeneous seedlings of genotypes with superior agronomic performance.

Twenty days after seeding, seedling segments germinated in vitro were used as explant sources. Three successive experiments were performed: one to test the effect of the explant source and combinations of two growth regulators, auxin indole acetic acid, IAA and kinetin KIN , on the morphogenetic response; another to investigate the effect of the combination of growth regulators on the morphogenetic response of hypocotyl segments, and another to evaluate how sucrose concentration affects the development of adventitious shoots.

The best shoot induction was obtained using hypocotyl segments and stem apices, while rhizogenesis was greatest in leaves with a petiole. Only sucrose concentration influenced shoot proliferation in the two S. Chemical Constituents from Solanum glabratum Dunal var.

In the present study, three spirostan saponins and one flavonoid glycoside were isolated from the active n-butanol fraction through a bio-guided fractionation approach. The structures of the isolated compounds were elucidated based on their MS, one dimensional and extensive two dimensional NMR spectral data.

Among the isolated metabolites, compound 3 showed the highest cytotoxic activity in both PC3 and HT29 cell lines with an IC 50 values of St-Hil, Solanaceae.

In this work, a pharmacobotanical study of Solanum crinitum Lam. Crinitum Child. The three species are commonly named "jurubeba", "fruta-de-lobo" and "lobeira", and they are used in the folk medicine for the treatment of diabetes and others diseases. The three species studied share various morphological characters, like shrub and tree forms, the velutinous abaxial indument, the presence of bristles, the flower with stellate-pentagonal corollas ranging from violet to purple, and the fruit reaching up to 5 cm in diameter.

The principal parameters to distinct the three species studied were the morphology of petiole and base of the blade leaf, the indument of adaxial surface, the anatomy of mesophyll, the types of stomata and the leaf margin. Strains of Peru tomato virus infecting cocona Solanum sessiliflorum , tomato and pepper in Peru with reference to genome evolution in genus Potyvirus.

The three PTV isolates were readily transmissible by Myzus persicae. Isolate TM differed from SL1 and SL6 in causing more severe mosaic symptoms in tomato, and vein necrosis in the leaves of cocona. Pepper cv. The 5'- and 3'-proximal sequences of the three PTV isolates were cloned, sequenced and compared to the corresponding sequences of four PTV isolates from pepper, the only host from which PTV isolates have been previously characterised at the molecular level.

Phylogenetic analyses on the P1 protein and coat protein amino acid sequences indicated, in accordance with the phenotypic data from indicator hosts, that the PTV isolates from cocona represented a distinguishable strain. In contrast, the PTV isolates from tomato and pepper were not grouped according to the host. This subgroup of closely related potyvirus species was also distinguishable from other potyviruses by their more uniform sizes of the protein-encoding regions within the polyprotein.

In vivo and in vitro production of some genotypes of cherry tomato Solanum lycopersicum var. Cherry tomato is a variety that is poorly present at Macedonian fields, mainly due to the traditional habits of the consumers and the commercial tomato producers to grow tomato varieties with large fruit. Cherry tomato - Lycopersicon esculentum Mill. The features of this variety are portrayed its sweetness and aroma, which further enriche the ta Fruit removal of a wild tomato, Solanum granulosoleprosum Dunal Solanaceae, by birds, bats and non-flying mammals in an urban Brazilian environment.

To verify diurnal and nocturnal removals, fruits were counted in several fruit bunches, being classified by size and color. Diurnal observations were made on plants to verify bird removal. A mist net was placed among the plants from the evening to h to verify bat consumption. Live traps baited with S. Nocturnal mammals and birds-diurnal mammals partitioned fruits similarly. Geoffroy, Terrestrial mammals were a marsupial and three rodent species.

Except for rodents, these vertebrates must be promoting the seed dispersal of S. Separation of four flavonol glycosides from Solanum rostratum Dunal using aqueous two-phase flotation followed by preparative high-performance liquid chromatography. Aqueous two-phase flotation followed by preparative high-performance liquid chromatography was used to separate four flavonol glycosides from Solanum rostratum Dunal. After aqueous two-phase flotation concentration, the flotation products were purified by preparative high-performance liquid chromatography.

The purities of the final products A and B were KGaA, Weinheim. Solanaceae A. In this study 21 taxa of Solanum L. The taxa analysed were Solanum affine Sendtn. Induction of cell death on Plasmodium falciparum asexual blood stages by Solanum nudum steroids. Solanum nudum Dunal Solanaceae is a plant used in traditional medicine in Colombian Pacific Coast, from which five steroids denominated SNs have been isolated. The SNs compounds have antiplasmodial activity against asexual blood stages of Plasmodium falciparum strain 7G8 with an IC50 between Ultrastructure of Withania Somnifera L.

Dunal pollen grains. Light, scanning and transmission electron microscopy were used to study the morphology and ultrastructure of Withania Somnifera L.

Dunall pollen grains. Light microscopic examination revealed that the pollen grains are tri- or tetrazonocoplate grains, approximately as long as broad, measuring um. Scanning electron microscopic observation showed that surface sculpturing of the pollen is scarbate-granulate. Ultrathin sections as examined by transmission electron microscope showed that the pollen contained numerous starch grains, lipid droplets, endoplasmic reticulum and vesicles of dictyosomes.

Two layers of the pollen wall were also distinguished, the outer wall exine divided into ektexine and endexine as well as the inner layer intine. The nutritive values of Withania pollen are discussed.

The importance of studying the ultrastructure of pollen grains as a new tool in palynology is also discussed. In Vitro Propagation of Withania somnifera L. Withania somnifera L. Dunal known as Ashwagandha is commonly used in traditional Indian medicine system.

It possesses immense therapeutic value against a large number of ailments such as mental diseases, asthma, inflammation, arthritis, rheumatism, tuberculosis, and a variety of other diseases including cancer. The therapeutic potential of W. The growing realization of commercial value of the plant has initiated a new demand for in vitro propagation of elite chemotypes of Withania. Micropropagation which is an important tool for rapid multiplication requires optimization of number of factors such as nutrient medium, status of medium solid and liquid , type of explant, and plant growth regulators.

Similarly, an efficient and reproducible in vitro regeneration system which is a prerequisite for the development of genetic transformation protocol requires precise manipulation of various intrinsic and extrinsic factors. Genetic relatedness among Solanum L. In spite of their economic and medicinal value, no adequate attention has been paid to the diversity, characterization and taxonomical identification of Solanum L.

In this study, Scanning Electron Microscopy SEM of seed coat morphology and isozyme electrophoresis were employed for studying the genetic variability and relationships among seven Solanum L. Scanning Electron Microscope SEM investigation of seed coat sculpturing showed three basic patterns namely; rugulate, reticulate and levigate.

The analyses on six enzymes were coded by 19 loci. The number of alleles ranged from one to three with a mean of 1. The proportion of polymorphic loci for Solanum L. The mean observed heterozygosity varied from 0. Mycorrhizal association between the desert truffle Terfezia boudieri and Helianthemum sessiliflorum alters plant physiology and fitness to arid conditions.

The host plant Helianthemum sessiliflorum was inoculated with the mycorrhizal desert truffle Terfezia boudieri Chatin, and the subsequent effects of the ectomycorrhizal relationship on host physiology were determined.

Consequently, M plants exhibited higher biomass accumulation, higher shoot-to-root ratios, and improved water use efficiency compared to NM plants. Total chlorophyll content was higher in M plants, and the ratio between chlorophyll a to chlorophyll b was altered in M plants. The increase in chlorophyll b content was significantly higher than the increase in chlorophyll a content 2.

Calculation of the photosynthetic activation energy indicated lower energy requirements for CO 2 assimilation in M plants than in NM plants Continuous measurements of CO 2 exchange and transpiration in M plants versus NM plants provided a complete picture of the daily physiological differences brought on by the ectomycorrhizal relationships. The enhanced competence of M plants to withstand the harsh environmental conditions of the desert is discussed in view of the mycorrhizal-derived alterations in host physiology.
