Figure 7From: Growth, seed development and genetic analysis in wild type and Def mutant of Pisum sativum LLight micrographs and seeds growth of F3 populations resulting from crosses between dwarf wild type (JI 2822) and dwarf mutant pea (JI 3020). (a-l) Light micrographs of segregant F3 sections. (a-d) Heterozygote genotype Def/def (+-) line 77. a Young seed of line 77 shows a less differentiated palisade layer. b Mature seed section of line 77 shows normal double palisade layer development. c-d Higher magnification of (a) and (b), respectively. (e-h) Homozygous dominant genotype Def/Def (++) line 1. e Young seed section of line 1. f Mature seed section of line 1. g-h Higher magnification of (e) and (f), respectively. i-l Homozygous recessive genotype line 33. (i) Young seed section of line 33 shows no distinct palisade layer. (j) Mature seed section of line 33. (k)-(l) Higher magnification of (i) and (j), respectively. (m) Relationship between seed fresh weight and pod age in F3 plants. AZ Abscission zone, CPL Counterpalisade layer, PL Palisade layer. Bars = 12.5 μm (a, b, e, f, i, and j); 25 μm (c, d, g, h, k, and l).Back to article page
