5. chacoense

Screening for no-heat mutants in Capsicum collections and populations is a common practice for pepper breeders, as capsaicinoid accumulation is unique to the members of genus. A second locus for control of capsaicinoid production exists in at least two other species, C. chinense and C. chacoense [82], and the mutation that revealed this second locus is called loss of vesicle (Lov). The blisters on the placental surface that fill with capsaicinoids are absent in these no-heat mutants. The gene product and map location of this mutation are not known. [Pg.120]

Interestingly, feeding experiments in Solatium chacoense L. (92) demonstrate that cholesterol (127), C07H4(5O, can be incorporated into solanidine (130), C2 H43NO, but the amount of steroid incorporated is very low and there has been more than one suggestion (93) that the route involves initial degradation of the fed cholesterol to acetate, followed by recreation of the entire skeleton.

Steroidal Alkaloids.—[26,27- C2]Cycloartanol (182) and [26,27- CJlanosterol (183) have been examined as precursors for solanidine (184) in Solarium chacoense, tomatidine (185) in Lycopersicon pimpinellifolium, and solanocapsine (186) in... [Pg.40]

Dehydrocommersonine was isolated from root tissue of S. chacoense. Tuber tissues of this species were devoid of glyco-alkaloids, while callus of two varieties of 5. tuberosum yielded typical potato glyco-alkaloids. The occurrence and toxicity of potato glyco-alkaloids have been reviewed. Studies continue on... [Pg.246]
