I know this is not exactly a "Plant Education" question (except that it
involves student research).....but does anyone know whether we can store
plant tissue (by quick-freezing it in liquid nitrogen, and then storing
it at -80C) and still get a good yield of mRNA?

i want know,plz, what does determine carbohydrate in which direction
transport or store and how does the leaf stop its carbohydrate
transport to a other parts of plant. and the other question is that
the carbohydrate storage of fuit is full and transport should be

My theory on space and matter is presently on the following URL:

It is called Dialogues on Matter. This theory is embedded in a
fictional framework. Chapter one deals with micromatter, chapter 2

Have you ever seen a plant with tree cotyledons?

it's an heliantus annuus
How can it be?

I believe this is the finest way to grow asparagus. I have 2 years
experience with this concrete block method especially with asparagus.
This year I am experimenting with strawberries via the concrete block
method. But with asparagus I have ample experience. I started using

i was given 2 packets of mixed cactus seed. i wonder if anyone could
provide me with some pointers on how to ID them.
both packets are from different brands but they contain the same three
types. i take this as that either they are the 3 most common or

So far my best contribution to gardening has been the concrete block
method where I use 16"x8"x8" block with their 2 holes as a sort of pot
for plants. I put the block over strawberries and asparagus and have the
plants grow out of the holes. Tomatoes are especially good when grown

Last year about this time I began a series of posts saying that using
standard concrete block 16"x8"x8' with their 2 holes are great for
garden plants in that they protect the plant, reduce weeds and grass, so
much easier to plant without ever using a rototiller, easy to mow,

hi. i was wondering why plants like crowberry have green leaves (or
needles). i understand they contain corotenoids (accessory pigments)
etc but it must be some kind of adaptation the plant has. also, why do
they (crowberry) appear to grow facing north, ie. where light intensity

I have placed a picture on my web site, showing a plant I am unable to
identify.  Please see http://www.astrostitch.co.uk/plant.htm.
The plant was situated amongst Common Cleavers and Brambles by the edge of a
nature trail (disused rail track) in Nottinghamshire, England.  The ...

Dear Plant-ed folks:
I have some colleagues in chemistry that want to grow some carrots and
potatoes in a pesticide free environment.  Do you know if there are any
potting soils that are pesticide free?  I thought of mixing up our own

When I was on holiday in the Venice Beach/ Marina Del Rey area of Los
Angeles I saw an amazing conifer tree/large shrub, that I have never seen in
the British Isles. It was quite popular and seemed to be in a lot of gardens
in the area. I've tried searching the Web but it's near ...
