Table 2 Photomorphogenic mutations introgressed into cv. Micro-Tom

From: Convergence of developmental mutants into a single tomato model system: 'Micro-Tom' as an effective toolkit for plant development research

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]
