Seven samples of halophyte plants (Bassia hirsuta Aschers, Euphorbia peplis L., Salicornia europeae L., Calystegia soldanella, Calystegia sepium, Stachys maritima Gonan and Suaeda maritima Dumort,) were collected from a sand bar near the town of Pomorie (Bulgaria). The soil salinity ranged between 650 and 850 mg salts in 100 g soil. For comparison, two other samples from the species Calistegia ...

BACKGROUND AND AIMS Evolutionary transitions from heterostyly to dioecy have been proposed in several angiosperm families, particularly in Rubiaceae. These transitions involve the spread of male and female sterility mutations resulting in modifications to the gender of ancestral hermaphrodites. Despite sustained interest in the gender strategies of plants, the structural and developmental bases...

Maternal egg care is generally considered to be ubiquitous among the 1700 species of free-living Dermaptera. However, forms, costs, and benefits have only been studied in a handful species. In this study, we examined for first time earwig Forficula pubescens. Under standard laboratory conditions, set up 94 families containing mothers with either no eggs, reduced, normal or increased clutch size...

Background. Nelumbo nucifera Gaertn. and Nymphaea lotus L. var. pubescens (Willd.) are both aquatic rhizomatous perennial plants mostly found in the tropical region of Nepal, India, Bangladesh, China, Eastern Asia. famous for their different biological activities such as antidiabetic, antioxidant, hepatoprotective, antidiarrheal, anti-inflammatory properties. Objective. The present study majorl...

Hop (Humulus lupulus L.) is cultivated for the female fl owers, or “cones,” which traditionally have been used as a bittering and fl avoring agent in beer. Hop breeding historically relied on relatively simple selection techniques within established breeding lines. Supplementing current breeding material with new genetic sources would enhance a hop breeder’s ability to select for new traits. Th...
