SIGnAL T-DNA Search Engine (Plain Text)

1. Multiple-gene search:

Now this program allows users input genes, and returns all the T-DNA insertions (SALK, SAIL, Wisc, GABI, FLAG, RIKEN, SM and CSHL lines) and/or cDNA clones that the genes hit and displayed on the T-DNA Express rather than SALK lines only.



Please input gene names here: (for example: At1g01020)

2. Search for the new Affymetrix Arabidopsis chip (affyName or AtName):

This program allows users input multiple affynames or genes, and it returns all T-DNA insertions or cDNA clones that genes hit.

Note: Some probe sets, for example, 259447_s_at, 255882_x_at etc., of the new Affymetrix Arabidopsis chip will cross-hybridize with othe gene or genes, which could be found in the first part of the search return with keyword "CROSS_HYBS". Please identify actually expressed gene first and then search its T-DNA insertions.


Please input gene names or affy names here (At?gxxxxx or 12345_at):




3. Search by Affymetrix list for old chip (for example - "19866_at")

It returns T-DNA insertions or cDNAs.


Please input here:




4. Search by GO terms (for example - GO:0004672 or "protein kinase").

It returns two parts. Part I -- Gene and GO number; Part II -- then T-DNA insertions or cDNAs.


Please input here:




5. Blast with return of T-DNAs or cDNAs:

While you submit your sequence or sequences, this program does blast search the Arabidopsis genomic sequences first, then searches insetion database, and finally returns T-DNA insertions or cDNA clones. It takes a little bit longer time than usual.
NOTE: please include ">sequence_name" (fasta formate) in your submission to seperate sequences.
