Fig. 1: Phenotypes of wild-type and rcm1 mutant plants.

a Whole-plant morphology of the reduced-chlorophyll mutant (rcm1) and the wild type (Ligeer 87-5). Scale bars, 15 cm. b Phenotypes of Wild Type (WT) and rcm1 tomato fruits at four developmental stages. MG, mature green stage; BR, breaker stage; YR, yellow ripe stage; RR, red ripe stage. Scale bars, 2 cm. c Chloroplast ultrastructure of mature green fruits of wild-type and rcm1 mutant plants via transmission electron microscopy. P, plastoglobuli; TGS, thylakoid granum stacks. Scale bars, 10 μm (left) and 0.5 μm (right). d Chlorophyll content of fruit pericarps from wild type and rcm1 at the MG, BR, YR and RR stages. The data are presented as the means ± SDs (n = 6). e Carotenoid contents of fruit pericarps from wild type and rcm1 at the MG, BR, YR and RR stages. The data are presented as the means ± SDs (n = 6). f Phenotypes of the pistils of the wild type and rcm1 mutant. Scale bars, 2 mm. g Morphology of the leaves of the rcm1 mutant and the wild type. Scale bars, 2 cm. h Chloroplast ultrastructure of leaves of wild-type and rcm1 plants using transmission electron microscopy. SG, starch grains; TGS, thylakoid granum stacks. Scale bars, 0.5 μm. i Chlorophyll content of leaves from wild-type and rcm1 plants. The data are presented as the means ± SDs (n = 6). The asterisks indicate statistically significant differences according to t-tests: **, P-value < 0.01. nd, not detected
