Special Issue Information

Dear Colleagues,

Due to daily and monthly changes in living conditions, macroalgae are thought to acquire tolerance to these environmental changes to maintain growth and development normally. Understanding the regulatory mechanisms of stress response and development is quite important to breed novel strains of macroalgae with excellent characteristics against exposure to environmental stress under global warming conditions. To date, knowledge about life cycle and morphology of macroalgae have been extensively accumulated mainly for supporting their phylogenetic classification. However, physiological and molecular biological mechanisms of regulating response to environmental stress, development, and morphogenesis mostly remain to be elucidated, although environmental stress-inducible genes and some candidates of signaling factors have been identified.

This Special Issue highlights the latest findings related to the regulation and networks of growth, morphogenesis, and stress response at physiological, biochemical, and molecular levels. Thus, we intend to collect research articles, short communications, and review articles related to the above topics pertaining to freshwater and marine macroalgae.

In the marine red alga Pyropia yezoensis, filamentous phases of the life cycle, e.g., the conchocelis (sporophyte) and conchosporangium (conchosporophyte), proliferate by tip growth. In this study, we investigated the possible involvement of phosphoinositide turnover and actin polymerization in the spontaneous initiation and tip growth of new branches in isolated single-celled conchocelis cells using pharmacological treatments. Treatment with LY294002 and U73122, specific inhibitors of phosphoinositide-phosphate 3-kinase and phospholipase C, respectively, reduced side-branch formation and inhibited the elongation of branches. In addition, two inhibitors of the actin cytoskeleton, cytochalasin B (CCB) and latrunculin B (LAT-B), had similar effects on tip growth. However, CCB did not alter the branching rate of single-celled conchocelis, whereas LAT-B did. As CCB and LAT-B affect actin polymerization through different mechanisms, this result suggests differences in the contributions of actin polymerization to branch initiation versus tip growth. These findings demonstrate the critical and diverse functional roles played by phosphoinositide turnover and actin polymerization in the regulation of the initiation and maintenance of tip growth in the conchocelis phase of P. yezoensis.
