A stock list of the Carlsberg collection of flavonoid mutants was published in BGN Vol. 18:74-79. Since 1988 two new gene loci have been discovered and 39 proanthocyanidin-free mutants localized to an ant gene. In all these mutants the inheritance is recessive. The following additions should be made to the stock list in Vol. 18 (1988).
| Locus ant 13 | Proanthocyanidin-, catechin- and anthocyanin-free, located close to the centromere of chromosome 6 (2), 139 alleles. Ant 13 is a regulatory gene affecting the transcription of structural genes in the flavonoid pathway (3). |
| New alleles: ant 13-2010, -2011 (in Grit), -2024, -2068 (in Natasha), -5015 (in Monix), -5016 (in SP 185), -5032 (in Sonja), -5033 (in Kaskade), -5047 (in Lucia). | |
| Locus ant 17 | Proanthocyanidin-, catechin- and anthocyanin-free, located on the long arm of chromosome 3 (1), 177 alleles. Most likely coding for a co-factor participating in the hydroxylation of flavanones in 3-position (3). |
| New alleles: ant 17-375 (in Fanette), -405 (in Odin), -476 (in Zenit, -597 (in Morex), -604 (in Harrington), -2022, 2067 (in Natasha), -5024 (in Ack. 72/27/4), -5035, -5036, 5037 (in Video), -5038, -5039, -5040, -5042 (in Sonja), 5044 (in Ack. 27/220/8). | |
| Locus ant 18 | Proanthocyanidin-, catechin- and anthocyanin-free, shrunken grains, tentatively localized to chromosome 1 (1), 126 alleles. Ant 18 is the structural gene coding for dihydroflavonol reductase (3). |
| New alleles: ant 18-427 (in NZ 3789), -474 (in CC 031-78). | |
| Locus ant 22 | Proanthocyanidin-, catechin- and anthocyanin-free, located on the short arm of chromosome 1 (1), 6 alleles. Probably coding for a co-factor participating in the hydroxylation of flavanones in 3-position (3). |
| New allele: ant 22-603 (in Harrington). | |
| Locus ant 25 | Proanthocyanidin-free, varying expression of anthocyanin in plants, 10 alleles. Ant 25 might be a regulatory gene (3). |
| New alleles: ant 25-283 (in Hege 550/75), -420 (in Kaya), -461 (in Pamela), -477 (in Zenit). | |
| Locus ant 26 | Proanthocyanidin-free but synthesizes (+) catechin and a wildtype amount of anthocyanin, 4 alleles. Ant 26 controls the condensation of leucocyanidin and (+)-catechin to procyanidin (3). |
| Alleles: ant 26-483. -485, -486, -487 (all in Grit). | |
| Locus ant 27 | Proanthocyanidin-free but synthesizes trace amounts of (+)catechin and a wild type amount of anthocyanin, 3 alleles. Probably a regulatory gene (3). |
| Alleles: ant 27-488, -489, -490 (all in Zenit). |
The following corrections should be made to the stock list in BGN Vol. 18:74-79.
p. 75: ant 13-5322 is ant 13-522. p. 76: ant 17-353 is ant 17-352. ant 17-228 is ant 17-288. ant 17-381 is ant 17-318.
The following five ant 17 alleles should be included in the list: ant 17-185 (in Triumph), ant 17-221 (in Secobra 4743), ant 17-269 (in Secobra 18193), ant 17-388 (in Irene), ant 17-414 (in Kaya).
p. 77: ant 18-0260 is ant 18-260.
