Fertility of Herbivores Consuming Phytoestrogen-containing Medicago and Trifolium Species
Despite their unrivalled value in livestock systems, certain temperate, pasture, legume species and varieties may contain phytoestrogens which can lower flock/herd fertility. Such compounds, whose chemical structure and biological activity resembles that of estradiol-17α, include the isoflavones that have caused devastating effects (some of them permanent) on the fertility of many Australian sh...
متن کاملبررسی تاکسونومی عددی Trifolium resupinatum L. (شبدر ایرانی) و Trifolium fragiferum L. (شبدر توت‌فرنگی) با استفاده از ریزماهواره‌های جدید
Trifolium resupinatum و T. fragiferum دو گونه زراعی مهم تیره باقلائیان هستند. T. fragiferum به عنوان بخشی از خزانه وراثتی T. resupinatum در نظر گرفته شده است. در این مطالعه، ضمن بررسی انتقال‌پذیری زوج آغازگرهای T. pratense و T. repens به ژنوتیپ این دو گونه و معرفی نشانگرهای SSR (ریزماهواره‌های) جدید برای این گونه‌ها، میزان شباهت ژنومی آنها با استفاده از نشانگرهای SSR، به روش تاکسونومی عددی ارزی...
متن کاملPhysiologically-Mediated Self/Non-Self Root Discrimination in Trifolium repens has Mixed Effects on Plant Performance.
Recent studies suggest that plant roots can avoid competition with other roots of the same plant, but the mechanism behind this behavior is yet largely unclear and their effects on plant performance hardly studied. We grew combinations of two ramets of Trifolium repens in a single pot that were either intact, disconnected for a shorter or longer time, or that belonged to different genotypes. In...
متن کاملSelection for Self-fertility and Self-fertility in Alfalfa as a Tool for Breeding Strategy Assessment
Session 4 Conventional and Novel Methodologies for Plant Improvement ABSTRACT Cultivar development in alfalfa relies on heterosis, that has been mainly exploited by intercrossing selected clones from diverse gemplasm sources; an alternative way was proposed, based on developing double cross cultivars obtained by crossing clones selected for self-sterility, propagated by somatic seed. A differen...
متن کاملQTL Underlying Self-Fertility in Tetraploid Alfalfa
A potential strategy to decrease the levels of self-seed production during the seed increase stages of alfalfa (Medicago sativa L.) synthetic cultivar development is selection for decreased self-fertility. The underlying genetics of this trait have not been elucidated and, therefore, a study was designed to identify genetic determinants of alfalfa self-fertility. An F1 mapping population develo...
