Cell Wall Related Gene Families
We have segregated cell wall biogenesis into six distinct stages: substrate
generation, polymer synthesis, secretion, assembly, rearrangement during development,
and disassembly. Several gene families devoted to wall biogenesis representing
these six stages have been identified, and many more of the unannotated and
unknown genes remain to be examined. In this section we have provided the
current knowledge of the relevant gene family structure and annotated them
as to progress towards identification of availability of T-DNA insertional
mutants, if mutants have been identified by other investigators, and other
information gleaned from database searches. The next section on ‘mutants’
extends this list to EMS as well as T-DNA mutants that have been previously
characterized. Each Arabidopsis entry will contain access directly to SIGnAL’s
T-DNA collection. Accession codes in red indicate that a SALK hit has been
identified and is currently being directed to generation of homozygous lines
and on to FTIR screening. Those in blue indicate no SALK hit has yet been
recorded, but a link is still established to SIGnAL to give the chromosome
location and other links to annotation or information about gene function.
Ordering information through ABRC is also provided.
Do you have an interesting new gene family for us to consider? Do you desire us to place your special cell-wall gene family into our high priority for screening? Write us immediately!
