Studies have indicated that florivory and nectar robbing may reduce reproductive success of host plants. However, whether and how these effects might interact when plants are attacked by both florivores and nectar robbers simultaneously still need further investigation. We used Iris bulleyana to detect the interactions among florivory, nectar robbing, and pollination, and moreover, their effects on plant reproductive success. Field investigations and hand pollination treatments were conducted on two experimental plots from a natural population, in which Experimental plot was protected from florivores and Control plot was unmanipulated...

The plastid genome regions of two intergenic spacers, psbA-trnH and trnL-trnF, were sequenced to study the nucleotide diversity and phylogenetic relationships among Gladiolus cultivars. Nucleotide diversity of psbA-trnH region was higher than trnL-trnF region of chloroplast. We employed Bayesian, maximum parsimony (MP) and neighbour-joining (NJ) approaches for phylogenetic analysis of Gladiolus and related taxa using combined datasets from chloroplast genome. The psbA-trnH and trnL-trnF intergenic spacers of Gladiolus and related taxa-like Babiana, Chasmanthe, Crocus, Iris, Moraea, Sisyrinchium, Sparaxis and two out group species (Hymenocallis littoralis and Asphodeline lutea) were used in the present investigation...

Crocus sativus belongs to Iridaceae family and is the only plant species which produces apocarotenoids like crocin, picrocrocin, and safranal in significant quantities. Besides their organoleptic properties, Crocus apocarotenoids have been found to possess remarkable pharmacological potential. Although apocarotenoid biosynthetic pathway has been worked out to a great degree, but the mechanism that regulates the tissue and developmental stage-specific production of Crocus apocarotenoids is not known. To identify the genes regulating apocarotenoid biosynthesis in Crocus, transcriptome wide identification of zinc-finger transcription factors was undertaken...

Aggregations of Thaumatomyia glabra (Diptera: Chloropidae) were observed on flowers of Iris pallida Lamarck (Asparagales: Iridaceae), whereas no T. glabra (Meigen) were observed on nearby Iris germanica L. flowers. Sampling of T. glabra on I. pallida flowers revealed the presence of males only. In a previous study, T. glabra males were attracted to methyl anthranilate. We found methyl anthranilate in extracts of I. pallida flowers on which T. glabra aggregated, but not in extracts of I. germanica flowers. Applying methyl anthranilate to I...

Metabolic syndrome is a disorder which encompasses obesity, high blood glucose, high cholesterol levels and high blood pressure. Moreover, metabolic syndrome is considered as the most important risk factor for cardiovascular disease (CVD). CVD is the leading cause of mortality in the world for both men and women. Several chemical drugs are available to treat metabolic risk factors, but because of the safety, efficacy, cultural acceptability and lesser side effects, nowadays herbal therapy has a critical role in the treatment of these CVD risk factors...

Crocin is a pharmacologically active carotenoid pigment mainly present in the stigmas of Crocus sativus L. (Iridaceae). It has been well explored in experimental animal models of cognitive impairments, depression, anxiety and epilepsy. This study was designed to understand the effect of crocin on pentylenetetrazol (PTZ)-induced kindling development and its associated cognitive deficit in mouse. Crocin treatment at 5, 10 and 20 mg/kg p.o. doses showed a marked reduction in severity of PTZ-induced seizures. There was an increase in novel object preference index and discrimination ratio in the crocin-treated groups in the novel object recognition test...

Recent phylogenetic studies on Sisyrinchium strongly suggest that species classified in section Hydastylus and section Viperella belong to a single group of plants in recent adaptive radiation (Clade IV). These species neither present clear morphological differentiation among them nor show clear identification using DNA barcode markers. Thus, the main goal of this study was to develop a set of polymorphic microsatellite markers compatible for representative species of both sections to ensure variability that could be revealed by SSR markers...

As a green remediation technology, phytoremediation is becoming one of the most promising methods for treating petroleum hydrocarbons (PHCs)-contaminated soil. Pot culture experiments were conducted in this study to investigate phytoremediation potential of two representative Iridaceae species (Iris dichotoma Pall. and Iris lactea Pall.) in remediation of petroleum hydrocarbon-contaminated saline-alkali soil from the Dagang Oilfield in Tianjin, China. The results showed that I. lactea was more endurable to extremely high concentration of PHCs (about 40,000 mg/kg), with a relatively high degradation rate of 20...

Seed germination is the most important transitional event between early stages in the life cycle of spermatophytes and understanding it is crucial to understand plant adaptation and evolution. However, so far seed germination of phylogenetically closely related species has been poorly investigated. To test the hypothises that phylogenetically related plant species have similar seed ecophysiological traits thereby reflecting certain habitat conditions as a result of local adaptation, we studied seed dormancy and germination in seven Mediterranean species in the genus Romulea (Iridaceae)...

Mating patterns and natural selection play important roles in determining whether genetic polymorphisms are maintained or lost. Here, we document an atypical population of Lapeirousia anceps (Iridaceae) with a bimodal distribution of floral-tube length and investigate the reproductive mechanisms associated with this pattern of variation. Flowers were visited exclusively by the long-proboscid fly Moegistorhynchus longirostris (Nemestrinidae), which exhibited a unimodal distribution of proboscis length and displayed a preference for long-tubed phenotypes...

BACKGROUND AND AIMS: Flower colour polymorphism in plants has been used as a classic model for understanding the importance of neutral processes vs. natural selection in population differentiation. However, current explanations for the maintenance of flower colour polymorphism mainly rely on balancing selection, while neutral processes have seldom been championed. Iris lutescens (Iridaceae) is a widespread species in the northern Mediterranean basin, which shows a stable and striking purple-yellow flower colour polymorphism...
