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 کاملCharacterization of 12 polymorphic SSR markers in Veronica subsect. Pentasepalae (Plantaginaceae) and cross-amplification in 10 other subgenera1
PREMISE OF THE STUDY Microsatellite primers were developed in the perennial herbs of the diploid-polyploid complex Veronica subsect. Pentasepalae (Plantaginaceae) to investigate the role that hybridization has played in the evolution of the group, which includes several endangered species. METHODS AND RESULTS Twelve pairs of primers leading to polymorphic and readable markers were identified ...
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 کاملبررسی ساختار میوه در گونه‌های اندمیک و نیمه‌اندمیک Veronica L. (Plantaginaceae) در ایران
سرده Veronica از تیره Plantaginaceae یکی از سرده های بزرگ با حدود 450 گونه در جهان است. این سرده با 61 گونه در مناطق مختلف ایران پراکنش دارد. بنابر مطالعات گذشته ویژگی‌های ریخت شناسی و ریزریخت شناسی که در این سرده از اهمیت تاکسونومیک برخوردارند. از اینرو در این پژوهش سعی شده تا با بررسی ویژگی های ریخت شناسی، ریزریخت شناسی و تشریحی میوه در گونه های اندمیک و نیمه اندمیک ایران که کمتر مورد م...
متن کاملDisentangling phylogeography, polyploid evolution and taxonomy of a woodland herb (Veronica chamaedrys group, Plantaginaceae s.l.) in southeastern Europe
Southeastern Europe is a centre of European biodiversity, but very little is known about factors causing the observed richness. Here, we contribute to fill this gap by reconstructing the spatio-temporal diversification of the cytologically variable and taxonomically intricate complex of Veronica chamaedrys (Plantaginaceae s.l.), growing in open forests, forest edges and grasslands, with flow cy...
