Table 2 Photomorphogenic mutations introgressed into cv. Micro-Tom
Mutants | Mutation | Gene function | Origin | Reference |
|---|---|---|---|---|
aurea (au) | Deficiency in phytochrome chromophore biosynthesis | Defective for the phytochromobilin synthase gene | LA3280 cv. Ailsa Craig | [31] |
yellow green 2 (yg2) | Deficiency in phytochrome chromophore biosynthesis | Probably defective for the heme oxygenase gene | LA2514 cv. unknown | [32] |
high pigment 1 (hp1) | Increased response to light | Defective for a gene homologous to DDB1A of Arabidopsis, which codes a protein interacting with DET1 (HP2), a repressor of photomorphogenesis | LA3004 cv. Rutgers | [35] |
high pigment 2 (hp2) | Increased response to light | Defective for a gene homologous to DET1 of Arabidopsis, a negative repressor of photomorphogenesis | LA2451 cv. Manapal | [36] |
atroviolacea (atv) | Increased response to light | Natural variation from S. cheesmaniae, probably a non-functional allele of a negative regulator of photomorphogenesis | LA0797 Hybrid | [38] |
Intense pigment (Ip) | Increased response to light | Natural variation from S. chmielewskii, probably a positive regulator of light response, whose tomato allele is non-functional | LA1563 Hybrid | [38] |
