Individual and overlapping expression of homeotic genes in adjacent whorl of a flower determine the pattern of floral organ development. In an Arabidopsis mutant, floral organs are distributed as follows

WHORL 1 Sepal

WHORL 2 Petal

WHORL 3 Petal

WHORL 4 Sepal

Loss of function mutation in which one of the following genes would have caused the above pattern of floral organs development

Scientists have found that extracellular matrix components may induce specific gene expression in embryonic tissues such as the liver and testes. For this to happen, there must be direct communication between the extracellular matrix and the developing cells. Which kind of transmembrane protein would most likely be involved in this kind of induction?
