in vitro propagated and conventional runner propagated plantlets of strawberry (fragaria×ananassa duch) cv. ‘festival’ were transferred to the field and the size of crown for plants derived from both sources of planting material were compared. four sizes of the crown, i.e., < 0.5, 0.5-0.8, 0.8-1, and > 1 cm were taken from both sources of planting material. the results obtained flashed that veg...

as a diagnostic probe for P. syringae pv. tomato. In a survey of 75 plant-associated bacteria, pTPR1 hybridized exclusively to those strains that produced coronatine. The detection limit for this probe, which was labeled with the Chemiprobe nonradioactive reporter system, was approximately 4 x 103 CFU of lesion bacteria. During the 1989 growing season, a total of 258 leaf and fruit lesions from...

The importance of trees in a challenging urban environment ABSTRACT Our cities are a challenging environment for plants due to urban specific environmental stresses like urban heat island effects altering the radiative regime. Ecosystem service provision by urban trees qualifies the uptake of urban greening as an engineering solution to climate change. Further interdisciplinary research and wid...

Contamination with 2,4,6-trinitrotoluene (TNT) is widespread at sites of past munitions manufacture. It is moderately toxic to plants and highly toxic to some animals. Some aquatic plant species have been observed to promote degradation of TNT. The degradative activity is associated with the root systems but products are found in the surrounding medium. We have examined a range of sixteen gener...

Trehalose-6-phosphate synthase (TPS), as the key enzyme for the synthesis of plants trehalose, has effects of enhancing its anti-dehydration, as well as protecting biofilm, proteins, and others from harm. Additionally, reproductive isolation between species can be broken with transgenic technology, and beneficial gene of other species can be transformed and utilized to improve resistance of cro...

this comparison is not made here but a comparative study of the two drugs would make a most interesting investigation. One is also reminded of Rauwolfia from Ancient India which turned out to have a hypotensive action. The author has written a very interesting and useful book, but it is a pity that the documentation is rather limited. There has of late been a resurgence of interest in "natural"...
