Conservation of Thermospermine Synthase Activity in Vascular and Non-vascular Plants

In search for the role of thermospermine synthase gene in poplar vascular development

Background Plant polyamines are preferentially detected in actively growing tissues and have been implicated in growth and developmental processes such as embryogenesis, floral developmental, fruit ripening, senescence and stress responses [1]. Recently it has been established a link between polyamines and vascular development as it was found that, in Arabidopsis, the loss-of-function mutants o...

Liposomal and Non-Liposomal Formulations of Vitamin C: Comparison of the Antihypertensive and Vascular Modifying Activity in Renovascular Hypertensive Rats

Background: Liposomes constitute a promising drug delivery vehicle, and are believed to improve drugs’ effectiveness. This study was aimed to compare antihypertensive and vascular modifying activities of liposomal and non-liposomal forms of ascorbic acid. Methods: Forty-nine male Sprague-Dawley rats were randomly divided into seven groups (n=7): A sham vehicle-receiving (Sham-veh), hypert...

STUDY OF VASCULAR PLANTS OF BAMU NATIONAL PARK (FARS PROVINCE)

In this research, vascular plants of Bamu National Park (48000 ha.) situated in Fars province were studied. Analyses of all collected plants (450 species) showed that on account of climatic conditions, 94% of them were flowering in spring, also hemicryptophytes and therophytes possess abundant growth form with 39.6% and 23.5%, respectively. Phytogeographically, Irano-Turanian  elements comprise...

Morphogeometric Approaches to Non-vascular Plants

Morphometric analysis of organisms has undergone a dramatic renaissance in recent years, embracing a range of novel computational and imaging techniques to provide new approaches to phenotypic characterization. These innovations have often developed piece-meal, and may reflect the taxonomic specializations and biases of their creators. In this review, we aim to provide a brief introduction to a...
