The analysis of mutations affecting flower structure has led to the identification of some of the
genes that direct flower development. Cloning of these genes has allowed the formulation of …

The commonly observed proximal-to-distal decrease within inflorescences of fruit and/or
seed maturation per flower has frequently been attributed to com petition among developing …

The early development of the flower of Arabidopsis thaliana is described from initiation until
the opening of the bud. The morphogenesis, growth rate, and surface structure of floral …

The first step in flower development is the generation of a floral meristem by the
inflorescence meristem. We have analyzed how this process is affected by mutant alleles of …

Mutations in the homeotic gene agamous of the plant Arabidopsis cause the transformation
of the floral sex organs. Cloning and sequence analysis of agamous suggest that it encodes …

Photoperiodic plants perceive changes in day length as seasonal cues to orchestrate their
vegetative and reproductive growth. Although it is known that the floral transition of …

Abstract APETALA2 (AP2) plays a central role in the establishment of the floral meristem, the
specification of floral organ identity, and the regulation of floral homeotic gene expression in …

We describe allelic series for three loci, mutations in which result in homeotic conversions in
two adjacent whorls in the Arabidopsis thaliana flower. Both the structure of the mature …

Whereas naive T cells migrate only to secondary lymphoid organs,, activation by antigen
confers to T cells the ability to home to non-lymphoid sites,. Activated effector/memory T cells …

Carpels are essential for sexual plant reproduction because they house the ovules and
subsequently develop into fruits that protect, nourish and ultimately disperse the seeds. The …
