Progressive diebacks of outer canopy branchlets of Ceanothus crassifolius were repeatedly observed after rainless periods up to 9 mo in duration in the Santa Monica Mountains of southern California. Mean xylem pressures of branchlets near the end of drought were as low as -11.2 MPa (N = 22) with a mean of about 60 dead branchlets per shrub. Inoculation (N = 15) with three species of fungi previ...

We have used serial electron microscopy and 3-dimensional reconstructions of dendritic spines from Purkinje spiny branchlets of normal adult rats to evaluate 2 questions about the relationship of spine geometry to synaptic efficacy. First, do relationships between spine geometry and other anatomical indicators of synaptic activity suggest that spine size and shape might be associated with synap...

Isolation and identification of some potent anti-tumor compounds from medicinal plants, has motivated researchers to screen different parts of plant species for anti-tumor effects. It has been reported that several conifer posses cytotoxic activities on some human tumor cell lines. In this study, male and female branchlets or fruit of four different species of Iranian conifers (Juniperus Sabina...

The Vitaceae genus Causonis is found in tropical to temperate climates from Asia Australia, including the Pacific Islands. Rafinesque established 1930; however, Süssenguth classified it under Cayratia as a sect. Discypharia 1953. was resurrected 2013 using morphological and genetic evidence. We herein provided insight into diversity of trichomes’ micromorphology selected species this recently r...

Intracellular Ca(2+) transients are considered a primary signal by which astrocytes interact with neurons and blood vessels. With existing commonly used methods, Ca(2+) has been studied only within astrocyte somata and thick branches, leaving the distal fine branchlets and endfeet that are most proximate to neuronal synapses and blood vessels largely unexplored. Here, using cytosolic and membra...

In this study, the effects of different pruning heights and number of branches left were evaluated to determine the most effective pruning height and optimum number of branches to be left after branch thinning to increase seed yield production of Jatropha curcas. The experiment, which was conducted at the MMSU Experimental Station from 2009-2011, was laid-out in Split plot design and was replic...
