The Du Pont Company has an immediate job opening for a scientist 
with a Masters degree in biology to work on Arabidopsis molecular 
genetics.  The succesful candidate will join  a team of plant 
physiologists, biochemists, and geneticists to ascertain the 
resistance potential of plants to new herbicides and the possible 
mode of action of these chemicals.   Initially, activities will involve 
mutagenesis and screening of Arabidopsis plants for herbicide 
resistance.  Similar activities with microbes and other plant 
species could be envisioned in the future.

Du Pont is located in Wilmington, Delaware, an attractive east Coast 
location near Philadelphia and Baltimore.
We require:

%	Ability to organize, schedule, prioritize and carry out multiple 
tasks of a technical nature in an effective and timely manner.
%	Familiarity with (or ability to rapidly learn) modern laboratory 
techniques and instrumentation.
%	Good interpersonal skills and willingness to be part of a multi-
disciplinary research effort .
%	Good written and oral communications skills.
%	An interest in developing a strong research program in novel 
approaches to  agrichemical discovery.
%	Good computer skills.

Subject: Growth of plants(?)
Date: 12 Sep 92 20:38:33 GMT
Organization: Acadia University


 I'm in a jam guys.I need some information on the trimming
of plants.I have a small hemp plant growing and I'm now conducting
some experiments.
 What I'm currently doing is prunning.I want to develop a method
to get the best growth from the plant.
 So far I've cut the head of the plant and it's growth is divided
into two sections.I've left one to spread it's leaves twice and
the other to spread once before cutting.
 At present the one that I left longer before cutting(spread it's
leaves twice) is now much bigger than the other,almost if not twice
the size!
 I'm not so much debaiting on which method is correct,but
on the reasons why.
 I've come to the conclusion that the plant instinctively grew
faster in the other direction because at the present state it was not
dammaged.Even though the other side of the plant may start to catch up,
I'm almoost positive it won't.
 I guess if you were to block off a highway and subdivide it,making
a fork in the road,theorectically you would have equal traffic.But
if you blocked off one of the roads,you would get double the traffic
in the the other part of the plant,do you get it,that's why the plant
is twice as big on the part that I left alone.
 But there are many complications.If you were to look in the long run,
the extension that was cut first(section A) will have more forks 
in it's structure.Section B(the one cut latter) will have bigger and
stronger structure at first,but may loose ground in the long run.
 I guess that I'll have to wait and see,maybe I should get into the
field of study.
 If any information can be given it would be greaty appreciated
Mail is much more conservative,thankyou.

We have Master Gardeners, too, but somehow the word just isn't getting out.
I often pop into local nurseries, K-Marts, etc., and stop in the lawn
junk section -- mainly to see of the pruners have gone on sale (my students
seem to metabolize them).  I often wind up answering questions from the
general public. (Maybe I should quit carrying my Felco #2's-- people think
I work there. ;-)  )

I don't know what the solution really is.  I'd love to see *most* pesticides
put on a restricted list, but I don't think that one will fly around here.
In the meantime, I guess I'll continue my informal teaching wherever
I find someone to educate.

Well, one last public word on fighter aircraft (you get to appreciate

your citrus groves in the shadow of the Lebonese border):

I'm afraid I don't understand how two farmers, one with small acreage
and one with large, paying the same price for the same seed and
capable of delivering the same herbicide, differentially benefit
from genetically modified seed.  If the farmer is too poor to
afford the up-front cost of the seed/herbicide, then I can see
a differential benefit.  Along these lines, should we ban tractors because
they are expensive and give the large farmer higher returns than someone
who uses a mule to plow and a hoe to cultivate?  If "Social Justice"
types believe the non-mechanized farmer should be supported, they
are free to pay more for their food.  Many people buy high-priced
"organic" and "free-range" foods already, so clearly not everyone
is a slave to agribusiness.

If transgenic technology doesn't permit all desired genotypes to
be transformed, then conventional breeding will have to suffice for
moving the transgene into other germplasm.  Not at all different
from what they do now, BTW.

                  PLANT MOLECULAR BIOLOGIST

A three year post is available in the Biochemistry and Physiology
Department, Rothamsted Experimental Station.

The post is funded by a new grant from the AFRC's Global
Environmental Response initiative. The aim is to investigate,
using transgenic plants, whether differential partitioning of
nitrate assimilation between roots and shoots is a significant
factor in adaptation to plant growth under different
environmental conditions. Expression of nitrate reductase and 
nitrite reductase genes will be manipulated using sense and antisense 
constructs in order to generate 'mutants' of Lotus japonicus and
tomato, in which the partitioning of nitrate assimilation is altered. 

The duties of the appointee will be to make the necessary sense
and antisense gene constructs, initiate the plant transformations
and carry out the molecular, biochemical and preliminary
physiological analysis of the transgenic lines. At the end of the
first year, a second appointment will be made at the graduate
level to assist with the plant transformations and tissue culture
and with the biochemical and physiological analyses.

QUALIFICATIONS: a First or Upper Second Class honours degree in
a relevant subject and at least two years postgraduate
experience.  Candidates, preferably with a Ph.D, should have
previous experience in recombinant DNA techniques, and experience
with plant transformation and/or tissue culture would be an
advantage. 

SALARY: On HSO scale, 12,339 - 17,227 (pounds), depending on experience
and qualifications (pay award pending).

I believe that our near-total reliance on spray-and-pray has
allowed us to forget many of the *cultural* controls practiced only
50 years ago.  The recent weed texts spend MUCH more space on what-kills-
what than they do on the life history of the species.  Pick up Muenscher's
old weeds book and compare to a modern text.  My contention has always
been that you are better able to deal with a weed when you understand
its biology and you are better equipped to bring a variety of low-cost
controls into play.  

I think this is nowhere more evident than in home lawns, where pesticide
and herbicide use per acre is much higher than on an average "chemical
farm".   We're always looking for the easy way out, the no-brain solution.
Probably the most common question I get here in the herbarium from the 
general public is, "I found this in my yard.  How do I kill it before
it takes over?"  About 75% of the time, the species involved is a
garden plant that would never compete well with a well cared for lawn.*
And the low tech method, hand-weeding, might require 10 minutes to 
eradicate the "problem".

* This year's pest species in lawns: tomato and pepper plants (sewage sludge
application), Pelargonium seedlings, Poa annua (not a problem in this area),
and a Cardiospermum halicacabum (which is not winter hardy here).  Each 
of these homeowners wanted to apply a couple of tons of herbicide to their
lawns.
