Cultivation of Palmaria palmata: spore release, vegetative propagation and decontamination techniques.
… has been unsuccessful in the past due to poor spore survival, poor attachment to substrates, slow growth and degradation of biomass in tanks. This project aimed to find methods of growing P. palmata from spores and vegetatively for the development of a commercial crop. Initially, methods of …

Basidiosporogenesis and developmental anatomy of spore release in the Russulales: a systematic interpretation
… statismosporic, agaricoid and gasteroid taxa. Spore symmetry and ability to forcibly discharge spores are therefore fundamental systematic characteristics in the Russulales. Ballistosporic and statismosporic basidiosporogenesis however, has not been critically compared. Early and late …

The potential of Grateloupia filicina (Lamouroux) J. Agardh. for mariculture: culture experiments and observations on shore phenology
… initiated to determine suitable conditions for spore liberation and growth of G. filicina from spores. It was also attempted to propagate G. filicina sporelings from crust and thallus fragments. In addition, the proportions of plants in different life history phases were determined in August and …

STUDIES ON A CALCIUM-DEPENDENT ACTIVATOR PROTEIN, STRUCTURALLY AND FUNCTIONALLY HOMOLOGOUS TO CALMODULIN, FROM THE WATER MOLD ACHLYA AMBISEXUALIS RAPER.
… concentrated in the sporangial apices. After spore release bands of CaM persist around the exit pores of sporangia and cysts of Achlya and other members of the Saprolegniaceae studied. Calcofluor pulse-chase experiments indicate that sporangiogenesis involves a transition from tip growth to …

Impact of Meteorological Conditions and Maturity of Perithecia on the Release of Fusarium graminearum Ascospores
… fungal plant pathogen Fusarium graminearum. Ascospores of the fungus are released from perithecia on the residues of corn and small grains and can be transported long distances (>500 m) through the atmosphere. The overall objective of this work was to assess the influence of meteorological …

Epidemiological studies on primary inoculum of Venturia inaequalis and V. asperata for apple scab management
… ii) to understand the aerial dispersal of ascospores with the under-canopy irrigation, and iii) to identify the conditions of maturation of pseudothecia and ascospore discharge of V. asperata. The effect of irrigation was evaluated comparing irrigated and non-irrigated leaf litter. Irrigation …
