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] |
