Active transport of aromas Volatile organic compounds (VOCs) serve as invisible lines communication among host plants, pathogens, commensals, community groups, and, with flowers, their pollinators. Studying petunia Adebesin et al. show that VOCs do not passively diffuse out the cells but are actively shuttled across plasma membrane by an ABC (ATP-binding cassette) transporter (see Perspective Eberl and Gershenzon). Disabling results in damage to cell's membranes intracellular accumulation...
Structural changes accompanying the acclimation process were observed in leaves of sweetgum, Liquidambar styraciflua , using light and transmission electron microscopy (TEM). Comparisons made obtained from tissue culture, plantlets acclimated after transfer vitro environment to soil, field grown trees. Leaves cultured lacked a differentiated palisade parenchyma had spongy interspersed with large air spaces. Field showed distinct tissues high cell density. New an elongation upper mesophyll...
Liquidambar styraciflua L. seedlings and tissue-cultured plantlets were grown under high, medium, or low (315, 155, 50 microeinsteins per square meter second photosynthetically active radiation) quantum flux densities. Net photosynthesis, chlorophyll content, chloroplast ultrastructure of leaves differentiated from these conditions investigated. Seedling photosynthetic rates at light saturation positively related to pretreatments, being 6.44, 4.73, 2.75 milligrams CO2 decimeter hour for...
Pomegranate fruit is valued for its juice-containing arils and consumed marketed as whole fresh fruit, extracted arils, juice, syrup (grenadine), wine, teas, seed oil, other products. Recent consumption has rapidly increased attributable in part to reported health benefits that include efficacy against coronary heart disease, atherosclerosis, cancer, hypertension, infectious diseases. Within commercial orchards, the size of fruits produced can be quite variable even with trees same genotype...
Pomegranate [ Punica granatum (Punicaceae)] is characterized by having two types of flowers on the same tree: hermaphroditic bisexual and functionally male flowers. This condition, defined as functional andromonoecy, can result in decreased yields resulting from inability to set fruit. Morphological histological analyses were conducted using light scanning electron microscopy (SEM) characterize different flower observed pomegranate plants better understand their developmental differences....
Herbs have been long known to provide health-promoting benefits and are demonstrated antioxidant, anti-inflammatory, antibacterial, analgesic, antitumor activities. This study evaluated the effects of drying conditions extraction protocols on biochemical activity three culinary medicinal herbs: rosemary ( Rosmarinus officinalis ), motherwort Leonurus cardiaca peppermint Mentha piperita ). Leaf tissues were dried by sun, oven-dried at 40 °C, or 70 °C extracted using 80% methanol ethanol....
BACKGROUND: Herbs and spices have been used as food preservatives, flavorings, in traditional medicines for thousands of years. More more scientific evidence supports the medicinal properties culinary herbs. Colon cancer is third leading cause death USA, fourth most common form worldwide. The objectives this study were to evaluate antitumor activity five selected herbs grown under greenhouse conditions, potential synergistic effects among different herbal extract combinations. RESULTS:...
• Background and Aims Fertilization is essential in almond production, pollination can be limiting production areas. This study investigated stigma receptivity under defined developmental stages to clarify the relationship between morphology, pollen germination, tube growth fruit set.
Increasing evidence supports the potential health benefits of herbal extracts displaying antioxidant, anti-inflammatory and antitumour activities. Environment can have a pronounced effect on phenolic content antioxidant capacity. The objectives this study were to evaluate total contents capacities five different herbs grown under greenhouse field conditions assess their effects.High polyphenolic (TPP) (measured by Folin-Ciocalteu reagent method) high Trolox equivalent capacity (TEAC)...
Pomegranate trees ( Punica granatum ) produce large numbers of both hermaphroditic (bisexual) flowers that fruit and functionally male characteristically abort. Excessive production can result in decreased yields resulting from their inability to set fruit. Within flowers, sex expression appears follow a spectrum ranging those exhibiting strong weak pistil development. Unknown is the scope flower quality plays influencing production. A description floral characteristics how they vary with...
Abstract The anatomy of in vitro- and vivo-developed leaves sweetgum, Liquidambar styraciflua L., grown under three quantum fluxes (PPF), was evaluated using light scanning electron microscopy. Leaf characteristics both plants were modified by light: high irradiance associated with more compact mesophyll larger cells than low irradiance. However, when compared to vivo corresponding levels, all vitro had smaller, thinner smaller lacking extensive vacuolar components. Leaves developed larger,...
Abstract Tissue cultures of pecan [ Carya illinoensis (Wangenh.) C. Koch] were initiated from embryo explants collected weekly 12 weeks post-pollination until fruit maturity. Three derived immature embryos 14 postpollination produced primary somatic within 1 month following transfer modified woody plant medium (WPM) with 2.0 mgliter −1 2,4-D and 0.25 mg liter BA in the light to hormone-free dark. Scanning electron microscopy documented development secondary embryos, which followed a...

Abstract The acclimatization or hardening-off of in vitro -cultured sweetgum ( Liquidambar styraciflua L.) plantlets was studied using scanning electron microscopy. Comparisons were made among leaves differentiated culture, acclimatized after transfer from conditions, greenhouse seedlings, and mature trees. Leaves directly tissue culture had superficial, circular stomata epidermal cells with irregular, sinuous undulations the anticlinal walls. ellipsoid, depressed irregularly shaped cells....
Artemisinin, produced in the glandular trichomes of Artemisia annua L. is a vital antimalarial drug effective against Plasmodium falciparum resistant to quinine-derived medicines. Although work has progressed on semi-synthetic production artemisinin, field A. remains principal commercial source compound. Crop artemisia must be increased meet growing worldwide demand for artemisinin combination therapies (ACTs) treat malaria. Grower yields rely plants generated from seeds open-pollinated...
Plantlets were recovered from axillary bud cultures of muscadine grape (Vitis rotundifolia, `Summit'). Nodal segments 0.5 to 1.0 cm long cultured in Murashige and Skoog (MS) basal medium supplemented with 5, 10, 20, or 40 μ m BA. Best total shoot production was obtained 10 BA; higher BA levels, shoots unexpanded exhibited high mortalities. MS IBA enhanced rooting by increasing percentage number per plantlet. Shoots previously proliferated on 5 rooted significantly better than those...
ABSTRACT Scanning electron microscopy (SEM) was used to examine microstructural changes of pimiento peppers ( Capsicum annum L. cv. ‘Truhart’) treated with different NaOH (lye) solutions (1,4, and 9%), maintained at 80°C, for various times (1, 2, 3 min). Photomicrographs indicated that removes the epicuticular cuticular waxes, diffuses uniformly into fruit where it breaks down epidermal hypodermal cell walls, solubilizes middle lamella causing separation skin. In severe treatments lye also...
A simple and efficient protocol is reported for the isolation of RNA from embryos leaves pecan [ Carya illinoinensis (Wangenh.) K. Koch]. The method relies on suppression polyphenols interaction with their rapid removal homogenate by chloroform extraction. This produced abundant amounts high-quality RNA. likely to be useful Juglandaceous species other recalcitrant plants high levels phenolic compounds.
