REVIEW
Bibi Marjan Razavi, Hossein Hosseinzadeh
Metabolic syndrome is a disorder which encompasses with 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. Although several chemical drugs are available to treat metabolic risk factors, however, 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. The present 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 marked reduction in severity of PTZ-induced seizures...

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...

R B Miz, L O Tacuatiá, F W Cidade, A P de Souza, F Bered, L Eggers, T T de Souza-Chies
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...

Phytochemical investigation of the methanol extract of the aerial parts of Iris minutiaurea (Iridaceae) using column chromatography led to the isolation of a new xanthone glycoside, 1-hydroxy-3,5-dimethoxy-xanthone-6-O-β-D-glucoside (1), together with one known flavonoid glycoside (2). The structure of this new compound was elucidated by analysis of spectroscopic, including 1D (1H, 13C), 2D NMR (COSY, HMQC, HMBC), and high resolution fast atom bombardment mass spectrometric (HR-FAB-MS) data and enzyme hydrolysis...

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...

Hui Wang, María Talavera, Ya Min, Elodie Flaven, Eric Imbert
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...

PREMISE OF THE STUDY: Few-gene studies with broad taxon sampling have provided major insights into phylogeny and underpin plant classification. However, they have typically excluded heterotrophic plants because of loss, pseudogenization, or rapid evolution of plastid genes. Here we performed a phylogenetic survey of three commonly retained plastid genes to assess their utility in placing mycoheterotrophs. METHODS: We surveyed accD, clpP, and matK for 34 taxa from seven monocot families that include full mycoheterotrophs and a broad sampling of photosynthetic taxa...

The coastal environments of South Africa's Cape Floristic Region (CFR) provide some of the earliest and most abundant evidence for the emergence of cognitively modern humans. In particular, the south coast of the CFR provided a uniquely diverse resource base for hunter-gatherers, which included marine shellfish, game, and carbohydrate-bearing plants, especially those with Underground Storage Organs (USOs). It has been hypothesized that these resources underpinned the continuity of human occupation in the region since the Middle Pleistocene...

Crocus sativus, a monocot triploid species belonging to the Iridaceae family, is cultivated for its red stigmatic lobes of the carpel that constitute saffron. Flower development has been extensively studied in different plants. Different floral developmental pathways have been deciphered in many plants. In Crocus sativus, flower is the most important part and understanding the pathway underlying the flower development can pave the way for new avenues to improve its productivity and quality. The combination of class A genes (including APETALA1; CsAP1 and APETALA2; CsAP2), class B genes (including APETALA3; CsAP3 and PISTILLATA; CsPI) and class C genes (including AGAMOUS; CsAG) that are active in each whorl, determines the identity of the organs that will later develop in that whorl...
