24 The focus of my laboratory is the development of molecular
25 tools for the improvement of vegetable crops, in particular
26 pepper (<span style="font-style: italic">Capsicum</span>
27 spp.).</p>
29 <p dir="ltr" style="text-align: left; text-indent: 0.5000in">
30 Our first objective is the development of breeding lines
31 containing disease resistance genes and a concomitant
32 identification of molecular markers linked to these genes for
33 use in marker assisted selection. This work has been focused on
34 resistances to viruses such as TMV, TSWV (Jahn et al. 2000) and
35 CMV (Ben Chaim et al. 2001a) and to fungal diseases such as
36 powdery mildew caused by <span style=
37 "font-style: italic">Leveillula taurica</span>.</p>
39 <p dir="ltr" style="text-align: left; text-indent: 0.5000in">
40 Our second objective is the identification of the major genes
41 controlling fruit yield and quality parameters in pepper. We
42 associated the genes capsanthin capsorubin synthase and
43 phytoene synthase with mature fruit color changes (Popovsky and
44 Paran, 2000; Thorup et al. 2000). We identified a major
45 domestication gene, fruit polygalacturonase that is associated
46 with the soft flesh and deciduous fruit characters present in
47 wild <span style="font-style: italic">Capsicum</span> species
48 (Rao et al. 2003a). We mapped the <span style=
49 "font-style: italic">C</span> locus that is required for the
50 production of pungent fruit (Blum et al. 2002) and identified a
51 major quantitative trait locus (QTL) affecting the level of
52 pungency (Blum et al. 2003).</p>
54 <p dir="ltr" style="text-align: left; text-indent: 0.5000in">We
55 identified QTLs for major fruit quantitative traits such as
56 fruit weight, fruit shape, pericarp thickness and maturity (Ben
57 Chaim et al. 2001b, Ben Chaim et al. 2003a, Ben Chaim et al.
58 2003b, Rao et al. 2003b). The pepper QTL data allow us to
59 determine the degree of conservation of QTLs in <span style=
60 "font-style: italic">Capsicum</span> and among this genus and
61 other members of the Solanaceae family.</p>
