This review focuses on clonal propagation of mature trees by tissue culture. Most trees have
marked phase changes that result in a decline in their potential for somatic embryogenesis …

Plants represent a diverse group of organisms that have unique reproductive,
developmental, and physiological processes. Although morphologically simple, plants have …

We have characterized the floral phenotypes produced by the recessive homeotic apetala 1-
1 (ap1-1) mutation in Arabidopsis. Plants homozygous for this mutation display a homeotic …

The shoot system of higher plants passes through several different phases during its
development. Each of these phases is characterized by a unique set of morphological and …

Flowering in plants is a consequence of the transition of the shoot apex from vegetative to
reproductive growth in response to environmental and internal signals. The indeterminate1 …

In this study we investigated Arabidopsis thaliana (L.) Heynh. inflorescence development by
characterizing morphological changes at the shoot apex during the transition to flowering …

Aliphatic polyamines are polycationic organic compounds that have been implicated in a
wide variety of biological processes. Although, at present, it is difficult to relate any specific …

The homologous genes FLORICAULA (FLO) of Antirrhinum and LEAFY (LFY) of Arabidopsis
regulate the formation of determinate floral meristems. Transcripts of these single-copy …

A fate map for the shoot apical meristem of Zea mays L. at the time of germination was
constructed by examining somatic sectors (clones) induced by γ-rays. The shoot apical …

The plant body develops from groups of dividing cells, the meristems, that function as
permanent stem cell populations and enable the plant to increase in size continuously …
