Introduction: Olive leaf contains anti-inflammatory and COX-2 inhibitor compounds. Considering the role of the COX enzyme in seizures, this research was performed to assess the effects of this extract in treatment of seizures induced by PTZ. Methods: In this research, male Wistar rats (200±20 g) were injected intra-cerebroventricularly with 1 μl saline or olive leaf extract (125 μg, 250 μg ...

Chinese tallow (Triadica sebifera (L.) Small) is an aggressive invasive tree species that can be abundant in parts of its non-native range. This tree species has the capability of producing monocultures, by outcompeting native trees, which can be in or near wetlands that are utilized by breeding amphibians. Existing research suggests that leaf litter from invasive Chinese tallow reduces surviva...

Effect of various NaCI treatments (0, 50, 100, 200 and 300 mM) at different growth and development stages (tillering, boot swollen, flowering and anthesis) of two wheat cultivars  on the kinetic activity and PAGE electrophoretic pattern of leaf malate dehydrogenase was studied under greenhouse conditions. Ghods was salt-sensitive and Boolani was salt-tolerant. In general, in response to salinti...

The monitor and prediction of crop developmental stages, particularly harvest time, play an important role in planning greenhouse cropping programs and timetables by cut rose producers. There have been many scientific reports on the application of image analysis technology in estimating greenhouse crop growth stages. In the present research, we studied leaf color variations over time by taking ...

During greening of fat-storing cotyledons, the functional properties of the microbody population changes from that of glyoxysomes to that of leaf peroxisomes. The amount of microbody protein per cell is assumed to be substantially reduced [ 1,2,3] . Little is known about the mechansim of this change of microbody function. Recently, data obtained from labeling of microbody membranes with Cl4 and...

After initiation of the leaf primordium, biomass accumulation is controlled mainly by cell proliferation and expansion in the leaves(1). However, the Arabidopsis leaf is a complex organ made up of many different cell types and several structures. At the same time, the growing leaf contains cells at different stages of development, with the cells furthest from the petiole being the first to stop...

Plants need to allocate some of their limited resources for defense against herbivores as well as for growth and reproduction. However, the priority of resource allocation within plants has not been investigated. We hypothesized that plants with extrafloral nectaries (EFNs) invest more chlorophyll around their EFNs-to support a high rate of carbon fixation there-than in other leaf parts of youn...

To assess the role of auxin flows in plant vascular patterning, the development of vascular systems under conditions of inhibited auxin transport was analyzed. In Arabidopsis, nearly identical responses evoked by three auxin transport inhibitor substances revealed an enormous plasticity of the vascular pattern and suggest an involvement of auxin flows in determining the sites of vascular differ...
