Flowers are a key source of released fragrance volatiles in the biotic world. Despite fact that volatile organic compounds (VOCs) have low molecular weights, polarity, and vapour pressures, process release is influenced by floral tissue’s morphology, anatomy, cellular properties. Polianthestuberosa L. flowering plant Agavaceae family (also known as Asparagaceae Amaryllidaceae some botanists) co...

BACKGROUND AND AIMS Microsporogenesis leading to monosulcate pollen grains has already been described for a wide range of monocot species. However, a detailed study of additional callose deposition after the completion of the cleavage walls has been neglected so far. The study of additional callose deposition in monosulcate pollen grain has gained importance since a correlation between addition...

PREMISE OF THE STUDY Ten polymorphic chloroplast microsatellite (cpSSR) markers were developed and characterized in an endemic and endangered herb, Maianthemum bicolor (Asparagaceae s.l.), for use in conservation genetics. METHODS AND RESULTS Primer sets flanking each of the 10 cpSSR loci in noncoding regions of the chloroplast genome of M. bicolor were designed. These cpSSR markers were test...

Karyological investigations were carried out on four species of Bellevalia Lapeyrouse, 1808 and Muscari Miller, 1758 (Asparagaceae) sampled in contrasting bioclimatic conditions of Algeria. The endemic Bellevalia mauritanica Pomel, 1874 was found to have a tetraploid cytotype 2n = 4x = 16 and an octoploid 2n = 8x = 32 which is a new report. The chromosome number 2n = 2x = 18 in Muscari comosum ...

We report an efficient, simple and cost-effective protocol for the isolation of genomic DNA from Ornithogalum species. Our modification of the standard CTAB protocol includes two polyphenol adsorbents (insoluble PVPP and activated charcoal), high NaCl concentrations (4 M) for removing polysaccharides, and addition of phenol to remove proteins and other contaminants. DNA yield obtained with our ...

This study evaluates Ornithogalum brevipedicellatum, which was previously accepted as a synonym of O. oligophyllum, as a separate distinct species and discusses the similarities and differences between O. brevipedicellatum and its related species (O. oligophyllum and O. pamphylicum). Similarities and differences among these species were identifi ed by morphological and molecular studies. The le...
