physicochemical properties of plant viruses?

Plant viruses, like all other viruses, are obligate intracellular parasites that do not have the molecular machinery to replicate without the host. The plant viruses are defined as viruses pathogenic to higher plants. While this article does not intend to list all plant viruses, it discusses some important viruses as well as their uses in plant molecular biology.Most of the virus types that have been discovered infecting plants are single-stranded RNA viruses, and have rod-shaped capsids with protein units arranged in a spiral.One novel characteristic of Plant viruses is that some of the viruses, instead of having a segmented genome packaged into the same particle as happens in animal viruses, some of the plant virus species are multipartite. This is when, for example, in the Gemini virus genome there is two incomplete icosahedral particles joined as a pair and can contain two circular single stranded DNA molecules. This has been suggested that this method employed by plant viruses of separately packaging the genome solves the problem of organisation and packaging problems associated with the segmented genome.There are two major ways the viral diseases may spread: horizontal transmission and vertical transmission. Horizontal transmission means that the infection comes from the outside, usually through damage done to the plant by vegetative propagation, grafting, vectors (some viruses can propagate in plant host and vector animal) or mechanical transmission. Vertical transmission refers to the plant inheriting the disease from a parent; this is often via seed but is not as prevalent as horizontal transmission. Plant viruses frequently have the ability to stunt growth and diminish crop yield.\nThe outer surfaces of plants are composed of protective layers of waxes and pectin, but more significantly, each cell is surrounded by a thick wall of cellulose overlying the cytoplasmic membrane.There are single stranded, double stranded RNA and single stranded, double stranded DNA plant virus.

Quite simple really. viruses can reproduce only inside a living cell.but bacteria can reproduce outside too .\n\nbut it depends what you are  talking about .you'll have to consider the temperature and pH conditions .viruses can survive higher temperatures than bacteria.

YES.....if for example u are in contact with the virus.....it cannot be washed off with water....u gotta use soap also........or if u want to disinfect it in some food item....cook it or heat it at more than 70 degree CELSIUS for some seconds b4 consuming.....

bacteria, viruses, cyanobacteria or fungi?  or do you mean specific examples

Viruses themselves are not alive. Most virologists consider them non-living, as they do not meet all the criteria of the generally accepted definition of life. They are similar to obligate intracellular parasites as they lack the means for self-reproduction outside a host cell, but unlike parasites, viruses are generally not considered to be true living organisms. Among other factors, viruses do not possess a cell membrane or metabolise on their own.\n\ncompter viruses are not alive either.

The volume of the virus is pi*(200^2)* 1500=1.884*10^7 cubic angstroms.   This goes into.24 cc 1.27*10^16 times.Divide 1 gm. by this figure and you get the weight of 1 virus=7.87*10^-17 grams.   That's the weight of a few million hydrogen atoms, which sounds about right.

i think human diseases r interesting. besides that, how bout healing properties of some tradisional herbs/plants? i'm currently working on pathogenic bacteria. maybe u can try to look into pathogens too? since pathogen like SARS, avian influenza and HIV are emerging problems for mankind... most importantly, which area r u interested?

A virus particle, known as a virion, is little more than a gene transporter, consisting at the most basic level of a genome contained within a protective casing of protein.These structures can range in size from less than 20 nanometers up to 400 nanometers. you need an electron microscope to see them, and in many cases you can only see their shadow, or figure.Remember that viruses cannot reproduce on their own.Viruses are non-living particles and can only replicate when an organism reproduces the viral RNA or DNA. Viruses are considered non-living by the majority of virologists because they do not meet all the criteria of the generally accepted definition of life.

A virus is neither a plant nor an animal. It acts like a living organism when inside the body of a host, but behaves like a non living thing when outside of it! Hence viruses are able to exist for thousands of years...\nBacteria on other hand, is a living being and hence is mortal too.
