Viral defences would be absolutely sterling!

Truly, you are a goddess!

Well, the absolute basics are that plants can shed infecte leaves to prevent viruses and other infections from spreading.. Just a sec and I'll give you the genetics..

That would be absolutely amazing.

Found it smiley - biggrin, will type it up in bits..

The Hypersensitive Response (HR)

smiley - starTo kill the pathogen directly, genes such as chitinases and glucanases are swithced on, along with genes for biosyntheses of phyroalexins
smiley - starHydrogen peroxide is also produced
smiley - star to restrict pathogen growth, genes for lignin biosynthesis are also induced

Host resistance

smiley - star within a species, some plants have developed genetically inherited ways of recognising that they are being attacked and resisted by disease

smiley - starPlants do not produce antibodies and don't have a ciculatory system. Therefore each cell must be capable of recognising pathogen attack and defending against it

Thank you so much.

erm, do you need the basic stuff, like having a waxy cuticle to keep out pathogens, or can you sort that?

anyway

Heritable resistance genes

smiley - star recently, a number of resistance genes have been cloned from plants
smiley - star many of these posess similar features
smiley - starthe proteins they encode often contain region involved in recognition, and a signalling domain
smiley - star attempts are now being made to engineer resistance genes into commercial cultivators by transformation, removing the need for expensive backcross programes

gene-for-gene theory

a gene product in the plant recognises the product of a gene (Avirulance gene) in the pathogen, and this recognition triggers hypersenstve defense response.

There's more, but it get's complex, and hard to explain without diagrams. bed now though, tired smiley - zzz

Think might just about manage a bit more, mind the spelling however smiley - winkeye

Systematic acquired response

smiley - star Once the plant has undergone HR, it is often better able to resist subsequent attack, including by other pathogens and in other parts of the plant
smiley - starThis systematic acquired resistance has been used as a means of 'immunising' plants, and chemicals have been developed for this

Oh, you've gone anyway smiley - laugh, I won't go on about non-host resistance then smiley - laugh

Uh oh, no viruses (viri?) for me, please!

Unless, of course, they're computer viruses.

Plant viruses, so nothing to worry about smiley - laugh

Plant viruses. Cool. I never thought about the fact that plants can be atacked by viruses as well. Wow. Not that i got much of that stuff, but I am after all, only in high school. Which reminds me that i must still put that one peanut plant into a bigger pot or it will surely shrivel up and die. I will promptly see to that.smiley - run
Oh, and i must water my cacti, it's been a while
(Cacti are about the only plants that i can keep really healthy on my own, because i only have to remember to water them about once a monthsmiley - smiley)

Well, then I will go about tending the vegetation of my Republic.

Plants get viruses alright smiley - bigeyes
Yup, cacti are nice and easy to look after, you just have to remember not to water them mid October-March, and feed them a bit in the summer. Easy. smiley - biggrin

The UBC seems to be going through troubled times. First Penguins, then Computers, now we are even fearing the plants smiley - yikes!!

But no, I believe the plants are quite happy so far.smiley - biggrin

Good, good, perhaps the plants can be our allies. Cacti can handle spikes quite well. smiley - biggrin

Thank you so much Unc!

and smiley - sorry for going off. I figured you'd stop sooner.

My room has no plants, I think I'm safe from them.
