The diploid wild strawberry Fragaria nilgerrensis Schlechtendal ex J. Gay mainly distributed in Southwest China has many excellent traits and a small genome. A high-quality genome of F. is available, but functional genomic research remains scarce. In the present study, to promote nilgerrensis, ethyl methane sulfonate (EMS) was used mutagenize apical meristems, appropriate EMS mutagenesis dosage...

The ability of the shoot apical meristem to multiply and distribute its meristematic potential through the formation of axillary meristems is essential for the diversity of forms and growth habits of higher plants. In the lateral suppressor mutant of tomato the initiation of axillary meristems is prevented, thus offering the unique opportunity to study the molecular mechanisms underlying this i...

Plant development is a biphasic process. Pattern formation during embryogenesis generates a basic body organisation, including self-maintaining stem-cell systems called meristems at opposite ends of the main axis of polarity. During post-embryonic development, the meristems produce new organs with reference to the existing body, transforming the juvenile seedling into the species-specific adult...

a methodology to regenerate whole plants of fig tree (ficus carica cv. jaami-e-kan) from apical meristem of greenhouse plantlets was developed. two meristematic explants size (0.2-0.4 and 0.5-0.7 mm), two kinds of culture media and three concentrations of 6-benzyladenine (0.5, 1 and 1.5 mgrl-1) were tested as a completely randomize design (crd) with a simple factorial arrangement for establishm...

We have isolated and characterized AtREM1, the Arabidopsis ortholog of the cauliflower (Brassica oleracea) BoREM1. AtREM1 belongs to a large gene family of more than 20 members in Arabidopsis. The deduced AtREM1 protein contains several repeats of a B3-related domain, and it could represent a new class of regulatory proteins only found in plants. Expression of AtREM1 is developmentally regulate...

The maintenance of meristems throughout plant ontogeny allows the development of a diversity of structural forms from the same genetic base. Examination of the common and contrasting features of these meristems leads to the outline of common regulatory themes in meristem development. In particular, by including comparisons with embryogenesis research, we see that hormones and factors that are g...

In flowering plants, the founder cells from which reproductive organs form reside in structures called floral meristems. Recent molecular genetic studies have revealed that the specification of floral meristems is tightly controlled by regulatory networks that underpin several coordinated programmes, from the integration of flowering signals to floral organ formation. A notable feature of certa...
