Localization of mRNAs contributes to the generation and maintenance of cellular asymmetry in a wide range of organisms. In Saccharomyces cerevisiae, the so-called locasome complex with its core components Myo4p, She2p, and She3p localizes more than 30 mRNAs to the yeast bud tip. A significant fraction of these mRNAs encodes membrane or secreted proteins. Their localization requires, besides the...

The objective of this study was to manipulate the intracellular pools of sucrose, and investigate its role in regulating plant growth, phenology (leaf senescence and bud break) and fibre development. This objective was achieved by differentially expressing an Arabidopsis (Arabidopsis thaliana L. Heynh.) sucrose phosphate synthase (SPS) gene in hybrid poplar (Populus alba L.xPopulus grandidentat...

Insect herbivory can negatively or positively affect plant performance. We examined how a stem gall midge Rabdophaga rigidae affects the survival, growth, and bud production of current year shoots of the willow Salix eriocarpa. In mid-May, the gall midge initiates stem galls on the apical regions of shoots. The following spring, galled shoots had thicker basal diameters and more lateral shoots ...

Investigation into total phenolics and their spectrum in the buds and corms of saffron Crocus and a study of polyphenol oxidase changes in the apical bud during different stages of growth and development showed that changes in the growth and development of the apical bud may be related to changes in the composition of phenolics in the corm. A sudden intense change in content and kind of ph...

Primary bud necrosis in grapevine is a physiological disorder observed in the compound buds. This study was conducted to investigate the anatomical changes in cv. Askari grapevine in winter dormant buds. Bud samples were taken from Askari grapevine at Sisakht vineyards, south-western of Iran. Compound buds were dissected and assessed under a binocular microscope at 10-40x magnification and a di...

Almond [Prunus dulcis (Mill.) D.A. Webb] is one of the most important cultivated fruit trees in Iran. Late frost in spring is a key limiting factor for almond productivity given that almond trees flower early in the spring in comparison with other temperate fruit trees. To decrease frost injury in “Mamaei” cultivar, this study was carried out in factorial randomized complete block design (CRBD)...

the cornelian cherry is one of those less common but, nevertheless, interesting fruit species found in serbia which can be used both for food and medicine. due to a great importance of cornelian cherry fruits as safe food and a wide interest in growing this fruit species, this research was focused on examining the production technique of quality planting material of particularly large-fruit sel...
