Organisation of the catalogue.

4. Add itv: = Near isogenic tetraploid stocks.

ma: = Mapped in segregating populations.

Gross morphology.

Add at the end of the section:

'Q has been mapped in the distal region of 5A, flanked by Xrsq805(Embp)- 5A (proximal 4.6 cM) and Xpsr370-5A (distal 4.3 cM) (9542).'

Accumulation of abscisic acid (new section).

A quantitative trait locus (QTL) has been mapped on 5AL between Xpsr575- 5A (proximal) and Xpsr426 (distal) (9544).

Anthocyanin Pigmentation.

4. Purple Culm

Pc. itv: LD222*11/CS (Hope 7B) (9538).

Crossability with rye and Hordeum spp.

Insert: 'Crossability between wheat and Aegilops squarrosa is controlled by the Kr series of genes (9518).'

DNA Markers.

See 'Genetic nomenclature proposal' above for a proposal for the naming of AFLP loci.

Delete the present preamble and substitute,

'The following list catalogues DNA-marker loci that (1) have been detected either by Southern hybridization of DNA restriction fragments or as sequence-tagged-sites by amplification of DNA fragments with primers and (2) have been localized to specific wheat chromosomes. The list does not include the 5S RNA or the 18S 5.8S 26S rRNA (Nor) loci, which are included elsewhere in the catalogue. No attempt has been made to list orthologous loci in related species, although many have been identified (e.g., 950,951).

The nomenclature used is that published in the 1994 Supplement, except for some loci detected with 'known-function' clones, for which other nomenclature has been used in the publications cited. The reference(s) that follow the locus symbols designate the publication(s) in which the chromosomal locations or map positions of the loci were first reported. References that are in parentheses ( ) contain the listed locus symbol, while the symbols for loci for which the references are in brackets [ ] were assigned by the curators in accordance with the current nomenclature guidelines. Symbols previously assigned to loci appear as synonyms in brackets. Symbols for a few DNA markers detected with known-function DNA probes are marked with an asterisk, *, ;these are temporary, pending assignment of the laboratory designator.

Other chromosomes bearing markers detected with the same probe or the same primers are indicated in parentheses after the probe or the primers.'
