SAHA, histone deacetylase inhibitor causes reduction of aflatoxin production and conidiation in the Aspergillus flavus

Transcriptional regulation in eukaryotes occurs within a chromatin setting and is strongly influenced by posttranslational modification of histones.The regulation of histone acetyltransferases (HATs) and histone deacetylases(HDACs) is one of important post translational modification (PTMs).Aspergillus flavus is the main source of aflatoxin,the most important mycotoxins in the world and food supplies.HDACs can play an important role […]

Pollen morphology of Calochortus Pursh and its systematic position in the Liliaceae family

Pollen grain of eight species belonging to Calochortus were taken from the Herbarium in Komarov Botanical Institute of the Russian Academy of Science (RAN) and were studied by Light Microscopy (LM) and Scanning Electron Microscopy (SEM). Pollen grains of all the studied species were single, heteropolar, bilaterally symmetrical, distal-monosulcate, flattened-spheroidal to oblate, in outline with […]

Leaf epidermal analysis of some plants in the Ishiagu lead–zinc mining area of South Eastern Nigeria

The study examined the leaf epidermis of some plants growing in a lead-zinc mining area of Ishiagu, Nigeria with the aim of evaluating possible impacts of heavy metal stress on leaf structure. Seven dominant plant species, Adiantum caudatum, Alchornea cordifolia, Centrosema pubescens, Clotalaria retusa, Millettia aboensis, Urena lobata and Vitex doniana were selected for the […]

Comparison on allowable use of Bromus tomentellus in semi-steppe and mountainous rangelands of Alborz and Zagros

Current research was performed in selected sites of semi-steppe and mountainous rangelands of Alborz and Zagros. Bromus tomentellus is a key and palatable species which has a considerable portion in rangelands production. For this purpose, 40 similar species of Bromus tomentellus were selected in each site. Selected species were exposed to different harvesting intensities of […]

Ethnobatanical studies on non-medicinal plants of Shinaki Valley Hunza, Gilgit-Baltistan

Present investigation explores folk modes, means, ways, approaches and practices-in-use of indigenous floral, fungal and lichens wealth usages in the Hunza. Out of a total 108 species identified 35.45% were medicinal, 30.9% fuel wood, 38.2% used for food, 94.5% fodder and forage, 21.8% cash crops, 17.2% timber wood, 6.36% oil producing, 9% condiments and 24.01% […]

The effectiveness of combination Mahogany (Swietenia mahogany) seed and Sour Sup (Annona muricata) leaf pesticide to the time of stop feeding and LC50 Mortality on Armyworm (Spodoptera litura F.)

Spodoptera litura Fabr. is one of polyphagous insect that attacks lot of crop species. Integrated Pest Management (IPM) is a effort to suppress insect pest population. Utilization of plant materials as ingredients insecticide is considered necessary because biodegradable, relatively safe for human, animal, non-target as well as agricultural production. This study uses a combination of […]

Monthly and annual changes of forage production and consumption of Cymbopogon olivieri (Boiss) Bor., Case study: Jevengane Genou-Hormozgan Province, Iran

Forage production in rangelands differs at different times of the grazing season and also in the same months of different years. In the present, grazing capacity is calculated for one time during the grazing season which coincides with the maximum growth of rangeland species. This causes more livestock entry in to the rangeland during the […]

Study of the plant diversity in Hyrcanian forest (case study: Lajim forest, Mazandaran province, North of Iran)

Hyrcanian (Caspian) forest in northern Iran has a richness of biological diversity, with endemic and endangered species, and a diverse range of economic and social conditions. The aim of this study is a study of the plant diversity in Lajim forest, Mazandaran province, north of Iran (Hyrcanian forest). In this study 100 circle sample plots […]

Molecular cloning and expression profiling of a chalcone synthase gene from Ginkgo biloba, Scutellaria viscidula Bunge and Tree peony (Paeonia suffruticosa)

Chalcone synthase (CHS, EC 2.3.1.74) is a key enzyme of the flavonoid/isoflavonoid biosynthesis pathway. In this review, the characterization and expression profile of CHS was investigated from Ginkgo biloba, Scutellaria viscidula, and Tree peony (Paeonia suffruticosa) because of the CHS role in protecting the plants from harmful effects by synthesizing flavonoid compounds. CHS was isolated […]

Exploration of near-extinct folk wisdom on medicinally important plants from Shinaki Valley Hunza, Pakistan

Study explores near extinct Ethnobotanical wisdom on medicinaly important plants from Shinaki Valley of Hunza. Research attempted to save and surface rapidly dying healing and treatment practices alongwith the gradually perishing floral wealth from the area. A total of 108 phanerogamic species belonging to 37 families were recorded. Indigenous communities use 38 species (35.18%) for […]
