Using complementary techniques to distinguish cryptic species: a new Erysimum (Brassicaceae) species from North Africa.
PREMISE OF THE STUDY Cryptic species are superficially morphologically indistinguishable and therefore erroneously classified under one single name. The identification and delimitation of these species is usually a difficult task. The main aim of this study is to provide an inclusive methodology that combines standard and new tools to allow accurate identification of cryptic species. We used Er...
متن کاملCardiac glycosides from erysimum cheiranthoides.
Two new cardiac glycosides were isolated from the seeds of Erysimum cheiranthoides. Their structures were characterized as strophanthidin glycosides of 3-O-alpha-L-rhamnopyranosyl-(1-->4)-3-O-acetyl-beta-D-digitoxopyranosyl and 3-O-beta-D-glucpyranosyl-(1-->4)-alpha-L-rhamnopyranosyl-(1-->4)-3-O-acetyl-beta-D-digitoxopyranosyl.
متن کاملENDOPHYTIC SPECIES OF NEOTYPHODIUM ON SOME GRAMINEOUS SPECIES IN IRAN
Some members of the familyClavicipitaceae are endophytic and have mutualistic relationship with the plant family Poaceae. Their relationship is beneficial for both host and fungus. In the present investigation, endophytic fungi were isolated from seed and leaf sheath of hosts Festuca arundinacea, F. ovina, F. pratensis, Bromus tomentellus, Melica persica and Lolium prenne. Morphological charact...
متن کاملCharacterization of microsatellite loci in Erysimum mediohispanicum (Brassicaceae) and cross-amplification in related species.
PREMISE OF THE STUDY We have developed and optimized microsatellite loci from a genomic library of Erysimum mediohispanicum. Microsatellites were also tested for cross-amplification in 31 other Erysimum species. METHODS AND RESULTS A total of 10 microsatellite loci were successfully amplified. They were polymorphic for 81 E. mediohispanicum individuals from two locations in Sierra Nevada (sou...
متن کاملAssociation between floral traits and rewards in Erysimum mediohispanicum (Brassicaceae).
BACKGROUND AND AIMS Floral rewards may be associated with certain morphological floral traits and thus act as underlying factors promoting selection on these traits. This study investigates whether some traits that are under pollinator-mediated selection (flower number, stalk height, corolla diameter, corolla tube length and corolla tube width) in the Mediterranean herb E. mediohispanicum (Bras...
