Cover: Club-like petaloid organs formed by the seuss leunig agamous triple mutant flowers. Together, SEUSS and LEUNIG regulate the expression of the floral homeotic gene AGAMOUS to ensure proper floral organ identity. However, the role of SEUSS and LEUNIG in regulating floral organ shape is independent of AGAMOUS, as demonstrated in these club-shaped petals in the seuss leunig agamous triple mutant flowers. For further details, see article by R. G. Franks, C. Wang, J. Z. Levin and Z. Liu, in this issue, pp. 253-263.
