جنس Orobanche در ایران دارای 39 گونه است که شش گونه آن انحصاری منطقه "فلور ایرانیکا" است. در راستای تدوین تیره Orobanchaceae برای فلور ایران به زبان فارسی گونه Orobanche owerini برای اولین بار از ایران گزارش و ترسیم میگردد. O. schultzii برای دومین بار از ایران کزارش میگردد. گونه های O. cistanchoides٬stocksii .O٬ O. caucasica و O. bungeana که توسط مؤلفین قبلی به عنوان گونه‌های مستقل گزارش گ...
متن کاملEvolution of plastid gene rps2 in a lineage of hemiparasitic and holoparasitic plants: many losses of photosynthesis and complex patterns of rate variation.
The plastid genomes of some nonphotosynthetic parasitic plants have experienced an extreme reduction in gene content and an increase in evolutionary rate of remaining genes. Nothing is known of the dynamics of these events or whether either is a direct outcome of the loss of photosynthesis. The parasitic Scrophulariaceae and Orobanchaceae, representing a continuum of heterotrophic ability rangi...
متن کاملTesting the Hypothesis of Multiple Origins of Holoparasitism in Orobanchaceae: Phylogenetic Evidence from the Last Two Unplaced Holoparasitic Genera, Gleadovia and Phacellanthus
Orobanchaceae is the largest family among the parasitic angiosperms. It comprises non-parasites, hemi- and holoparasites, making this family an ideal test case for studying the evolution of parasitism. Previous phylogenetic analyses showed that holoparasitism had arisen at least three times from the hemiparasitic taxa in Orobanchaceae. Until now, however, not all known genera of Orobanchaceae w...
متن کاملHost-specific races in the holoparasitic angiosperm Orobanche minor: implications for speciation in parasitic plants.
BACKGROUND AND AIMS Orobanche minor is a root-holoparasitic angiosperm that attacks a wide range of host species, including a number of commonly cultivated crops. The extent to which genetic divergence among natural populations of O. minor is influenced by host specificity has not been determined previously. Here, the host specificity of natural populations of O. minor is quantified for the fir...
متن کاملTranscriptomes of the Parasitic Plant Family Orobanchaceae Reveal Surprising Conservation of Chlorophyll Synthesis
Parasitism in flowering plants has evolved at least 11 times [1]. Only one family, Orobanchaceae, comprises all major nutritional types of parasites: facultative, hemiparasitic (partially photosynthetic), and holoparasitic (nonphotosynthetic) [2]. Additionally, the family includes Lindenbergia, a nonparasitic genus sister to all parasitic Orobanchaceae [3-6]. Parasitic Orobanchaceae include spe...
