Abstract The greenhouse whitefly Trialeurodes vaporariorum is a major threat in tomato cultivation. In grown tomatoes non-trichome based resistance may be better suited than glandular trichome as trichomes interfere with biocontrol, which widely used. Analysis of collection recombinant inbred lines derived from cross between Solanum lycopersicum and galapagense showed to the T. on plants withou...
Trichomes are widely distributed on surfaces of different organs in the grape genus Vitis and are of taxonomic utility. To explore the morphology, structure and ontogeny of Vitis trichomes, we investigated the diversity and distribution of trichomes in 34 species of Vitis. Two main types of trichomes in Vitis are documented: non-glandular and glandular. Within non-glandular trichomes, ribbon an...
In this study we produced transgenic tobacco plants by overexpressing a serine proteinase inhibitor gene, SaPIN2a, from the American black nightshade Solanum americanum under the control of the CaMV 35S promoter using Agrobacterium tumefaciens-mediated transformation. SaPIN2a was properly transcribed and translated as indicated by Northern blot and Western blot analyses. Functional integrity of...
Global characterization of Artemisia annua glandular trichome transcriptome using 454 pyrosequencing
Plant defenses inducible by herbivorous arthropods can determine performance of subsequent feeding herbivores. We investigated how infestation of tomato (Solanum lycopersicum) plants with the Western flower thrips (Frankliniella occidentalis) alters host plant suitability and foraging decisions of their conspecifics. We explored the role of delayed-induced jasmonic acid (JA)-mediated plant defe...
Transgenerational phenotypic plasticity, whereby environmental cues experienced by parents alter the phenotype of their progeny, has now been documented in diverse organisms. Transmission of environmentally determined responses is known to occur through both maternal and paternal gametes, but the underlying mechanisms have rarely been compared. In addition, the persistence of induction over mul...
Foliar and petiole micro-morphological characteristics of some members the genus Vernonia namely; amygdalina Del. (bitter variety), (non-bitter cinerea (L) Less., galamensis (Cass.) adoensis Sch. Bip. in Jos, Nigeria was investigated to provide additional characters support existing taxonomic information regarding species. Epidermal peels fresh leaves were made transverse sections petioles cut ...
Xanthanolides, as the sesquiterpene lactones, are reportedly the major components for the pharmacological properties of X. strumarium L. species. Phytochemical studies indicated that the glandular structures on the surface of plant tissues would form the primary sites for the accumulation of this class of the compounds. As the interface between plants and their natural enemies, glandular tricho...
Trichomes originate from epidermal cells and can be classified as either glandular or non-glandular. Gossypium species are characterized by the presence of small and darkly pigmented lysigenous glands that contain large amounts of gossypol. Here, using a dominant glandless mutant, we characterize GoPGF, which encodes a basic helix-loop-helix domain-containing transcription factor, that we propo...
From glandular trichome o f Rosa rugosa, three major sesquiterpene hydrocarbons [acora3(4),7(15)-diene, carota-4(5),ll(12)-diene (isodaucene) and carota-l,4-diene], and two minor [daucene and acora-3(4),7(8)-diene] were identified. The presence o f these carotadienes, which are possibly precursors o f the corresponding C-14-oxygenated carotanoids, suggested that the formation o f the carotane s...
