    Notes: Summary One fertile and two male-sterile diploid plants were regenerated from the same callus after two cycles of protoplast culture from fertile Nicotiana sylvestris. Genetic studies indicated that the male-sterile trait was under cytoplasmic control. Progenies of each regenerated plant possessed different mitochondrial (mt) DNA restriction patterns. Both cms protoclone types were characterized by specific mtDNA deletions. In addition, a 40 kD mitochondrially encoded polypeptide is lacking in the cms plants.

    Notes: Abstract We show that the maximum principle holds for optimal periodic control problems governed by functional differential equations under a Lipschitz condition on the value functional. Generalizations to other boundary conditions are also considered.

    Notes: Abstract This paper discusses the optimal periodic control problem to minimize the cost function $$J(u) = \int_0^1 {g(t,x(t),u(t))dt} $$ subject to the functional differential system $$dx(t)/dt = f(t,x_t ,u(t)),x_1 = x_0 $$ andu(·) εU ad. The maximum principle as a necessary condition of optimal control is proved under the assumption that Eq. (4) and its adjoint equation (5) both have no nontrivial periodic solution with period of 1. In this paper, the control domainU is an arbitrary set inR m.
