5. Arabidopsis fruit is a silique, which is a dry dehiscent fruit that splits longitudinally along both sides. A papery membrane separates the seeds. (1) (2). (3) (a) Label the fruit structures on the diagram: valve, replum, and dehiscence zone. (b) The genes SHP1/2, FUL, and RPL, are involved in regulating Arabidopsis fruit development. What are the roles of these genes in the growth of the valve, replum, and dehiscence zone? (c) Use a diagram to illustrate the interactions between SHP1/2, FUL, and RPL gene products. Use →' for positive interactions (i.e., activation) and H for negative interactions (i e repression) O > ARY
