Evolution of morphological and climatic adaptations in Veronica L. (Plantaginaceae)
Perennials and annuals apply different strategies to adapt to the adverse environment, based on 'tolerance' and 'avoidance', respectively. To understand lifespan evolution and its impact on plant adaptability, we carried out a comparative study of perennials and annuals in the genus Veronica from a phylogenetic perspective. The results showed that ancestors of the genus Veronicawere likely to b...
متن کاملSystematics of Aspergillus species of subgenus Nidulantes in Iran
Aspergillus subgenus Nidulantes accommodates species of industrial and medical importance. Thirty isolates morphologically assigned to subgenus Nidulantes were studied, 25 isolated from cereals in the north and northwestern provinces and the rest from other substrates in Iran. Based on morphological and molecular data (sequences of the ITS rDNA and β-tubulin), nine species were identified belon...
متن کاملIntraspecific Polyploidy in Veronica Anagallis-aquatica L. (plantaginaceae) from North India
The present study investigates the cytological and morphological analysis, and intraspecific polyploidy in V. anagallis-aquatica L. which sampled from Kinnaur district of Himachal Pradesh in India revealed the existence of diploid (n=9) and tetraploid (n=18) cytotypes based on x=9. The tetraploid chromosome count (2n=36) in the species confirms the earlier chromosome report from India and other...
متن کاملPhenylethanoid and iridoid glycosides in the New Zealand snow hebes (Veronica, Plantaginaceae).
Snow hebes are the alpine cushion-forming plants of New Zealand Veronica, formerly classified as Chionohebe. The chemical compositions of Veronica pulvinaris and Veronica thomsonii were studied and 33 water-soluble compounds were isolated. The structures of 14 previously unknown esters of phenylethanoid glycosides were elucidated by spectroscopic analyses. Further, eight known phenylethanoids, ...
متن کاملHygrochastic capsule dehiscence supports safe site strategies in New Zealand alpine Veronica (Plantaginaceae).
BACKGROUND AND AIMS Hygrochasy is a capsule-opening mechanism predominantly associated with plants in arid habitats, where it facilitates spatially and temporally restricted dispersal. Recently, hygrochastic capsules were described in detail for the first time in alpine Veronica in New Zealand. The aim of the present study was to investigate whether hygrochastic capsules are an adaptation of al...
