Vol 85, No 4 (2016): Phyllotaxis and related topics

On the cover A computer simulation of phyllotactic transition frequent in the main axes of dicotyledonous plants and in lateral shoots of conifers. Rectangular simulation space represents the split-open surface of cylindrical shoot, stacked disks – the primordia of lateral organs. The initial 2:2 decussate phyllotaxis (GREEN DOMAIN) transforms into 2:3 helical one (BLUE DOMAIN) through addition of one parastichy inclined to the left (γ-dislocation). This is due to quite rapid, yet continuous decrease in the size of primordia (RED DOMAIN), changing their identity from cotyledons or prophylls (GREEN) to the leaf proper (BLUE).

On the cover Remembering summer roses – bright and beautiful winter flowers of Camellia sasanqua Thunb.; the plant, native to Japan, grows there in the mountains high, but also in the gardens, where it blossoms till February, often under the cover of a white snow; its evergreen shiny leaves are used for making tea.

On the cover The swallowtail butterfly (Papilio machaon L.) studying the mysteries of wild teasel inflorescence (Dipsacus fullonum L.). The first one is bijugate phyllotaxis emerging typically from the initial decussate one. The second is  bi-directional blooming, which starts from the equatorial area of the inflorescence. The regulatory mechanism of this peculiar behavior remains unknown.

On the cover Clematis ×jackmanii Moore – aberrant flower with the symptoms of meristic variation in the region of perianth. In addition, one half the tepal seen in a front (discolored) is a mosaic of the cell clones having different identities – of a tepal and of a leaf.

On the cover Galanthus nivalis 'Flore Pleno' resembles to some extent the floral mutant agamous of Arabidopsis thaliana. Its multiplied perianth contains, however, some remnants of generative structures. The male, pollen producing stripes of sporogenic tissue can be seen on the adaxial surface of some inner perianth parts. The trimery of the outer parts, typical for the snowdrop, is often replaced by the teramery or even pentamery, which makes 'Flore Pleno' an attractive example of meristic variation.

Vol 83, No 4 (2014): Evolution of plant cells

On the cover The sacoglossan sea slug Elysia timida – these slugs are the only animals known to perform photosynthesis using plastids they sequester from their algal food source, in this case the green alga Acetabularia. The stolen plastids (kleptoplasts) can remain photosynthetically active for months in the cytosol of the animals’ cells.

On the cover we present new ASBP logo, a symbol of our journal activity, publishing continuously the results of research. It pertains to indeterminate growth of the plant apical meristem producing lateral organ primordia in a regular sequence. The primordia layout is unique. It is rarely observed in nature transient state between two consecutive expressions of the main Fibonacci phyllotaxis.

On the cover Lagging behind the glow of Tiffany Blue – specimen of leafy liverwort Nowellia curvifolia (Dics.) Mitt., collected by Wiesław Fałtynowicz in Wigry National Park, Poland, observed under UV in fluorescent microscope. Blue fluorescence of the youngest parts of growing gametophyte is probably due to a dense cytoplasmic content of the cells. These contrast nicely with the berberine stained, amber cell walls of the older leaves and rhizoids.

Erratum The fern shown on the cover of ASBP issue Vol. 80, No. 3 (2011) has been erroneously identified. The frond with characteristically undulated pinnae belongs to Matteuccia struthiopteris (L.) Todaro.
