Dear netters,

Sorry again, but please neglect the second paragraph of my first 
mail (CAPS analysis of RLD ecotype). I would like to send you the 
RLD/CAPS results again. Dr. Eliana Drenkard in Dr. Fred Ausubel's 
lab. kindly informed me that my results will be included the next 
update of the CAPS tables in the Stanford Arabidopsis Database.

I have performed PCR-amplification/restriction digestion (CAPS 
analysis) in DNAs from RLD, Columbia ecotype (Col) and Landsberg-
erecta (Ler). The result of the CAPS analysis is as follows. I found 
that the restriction pattern of RLD DNA at a particular marker can 
be the same as either that of Col or that of Ler except for the GL1 
marker which confers the novel fragment pattern on RLD. 

In the BGL1 marker, the Sau3AI-restriction pattern of
RLD (0.9 kb + 0.4 kb) was identical to that of Ler. However,
the Sau3AI patterns of Col and Ler in my experiment were opposite
to those reported by Konieczny and Ausubel (1993). There was no 
Sau3AI site in a PCR product from Col, but a single site in products 
from both Ler and RLD.

In response to my inquiry, Dr. Eliana Drenkard in Professor Ausubel 
Lab. has kindly performed the CAPS analysis on the BGL1 marker, 
and has confirmed  that my BGL1 results are reproducible.

Thank you for your kind attention.
With best regards,

Hiroaki Ichikawa
