Stability and expression of bacterial genes in replicating geminivirus vectors in plants
(1989-04-11)
Bacterial beta-glucuronidase (gus) and neomycin phosphotransferase (neo) genes were introduced into coat protein replacement vectors based on DNA A of tomato golden mosaic virus (TGMV). Recombinant gus and neo vectors up ...
The behaviour of tomato golden mosaic virus DNA in cultured cells isolated from systemically infected tobacco leaves
(1989-03)
When callus tissue was cultured from leaf pieces taken from a Nicotiana tabacum cv. Xanthi nc. plant systemically infected with tomato golden mosaic virus (TGMV), TGMV-specific DNA persisted for up to 6 months in culture. ...
Geographical approach to international tourism
(1989-03-01)
Dr S.J. Page of the Department of Geography, Christ Church College, Canterbury, reports on the proceedings of a conference organized by the International Geographical Union (IGU) Commission of Tourism and Leisure, 13-20 ...
Vertical dispersal of plant pathogens by splashing. Part II : experimental study of the relationship between raindrop size and the maximum splash height
(1989-03)
This paper describes a simple experimental test of the theoretical relationship between raindrop diameter and maximum splash height proposed by Walklate (1989). This relationship contains two empirical parameters to model ...
HARP: A Parallel Pipelined RISC Processor
(1989)
HARP (the Hatfield RISC processor) is a reduced instruction set processor being developed at Hatfield Polytechnic, UK. The major aim of the HARP project is to develop a RISC processor capable of a sustained instruction ...
Spectropolarimetry of the 3-micron ice feature in molecular clouds. II : GL 2591, GL 2136, W 33A and Elias 29 (Rho Ophiuchi dark cloud)
(1989)
Spectropolarimetric observations in the 3-micron ice band are presented for the infrared sources GL 2591, GL 2136, W 33A and Elias 29 (Rho Ophiuchi dark cloud). Some continuum polarization measurements between 1.2 and 5.0 ...
A simple formulation of microtubule dynamics: quantitative implications of the dynamic instability of microtubule
(1989)
A simple formulation of microtubule dynamic instability is presented, which is based on the experimental observations by T. Horio and H. Hotani of coexisting, interconverting growing and shrinking microtubules. Employing ...
A Lateral Cap model of microtubule dynamic instability
(1989)
The co-existence and interconversion of growing and shrinking microtubules have been termed ‘dynamic instability’, and have been directly observed to occur under a variety of conditions in vitro and in vivo. Previous ...
