“…3 However, during its cultivation, several types of diseases caused by bacteria, fungi and parasitic copepods seriously affect the production and quality of U. pinnatifida. 1,4 Improvement of this important kelp is required, together with rapid propagation of good strains. Genetic engineering may provide a powerful approach to improvement by introducing important gene(s) into its genome or chloroplast.…”

BACKGROUND: Previously, tachyplesin gene (tac) has been successfully transferred into Undaria pinnatifida gametophytes using the method of microprojectile bombardment transformation. The objectives of this study were to compare and evaluate the performance of bubble-column and airlift bioreactors to determine a preferred configuration of bioreactor for vegetative propagation of transgenic U. pinnatifida gametophytes, and to then investigate the influence of light on vegetative propagation of these gametophytes, including incident light intensity, photoperiod and light quality to resolve the problems of rapid vegetative propagation within the selected bioreactor.

“…1,2 Undaria pinnatifida has a heteromorphic life cycle with an alternation between a microscopic haploid gametophyte generation and a macroscopic diploid sporophyte generation. Sporophytes have long been an important food resource in Japan due to its high levels of protein, minerals, vitamins and dietary fiber.…”

“…Also known as 'Atlantic Wakame', it is similar to the true 'Wakame' Undaria pinnatifida which is extensively cultivated in Japan, eastern China and South Korea (Yamanaka & Akiyama 1993). A. esculenta has been cultivated in Ireland for the last 15 yr (Kraan & Guiry 2001) and is an economically attractive species due to its high growth rate of up to 10 cm d −1 (Druehl et al 1988), as well as being native to Irish coastal waters (Kraan & Guiry 2001).…”

There has been an increase in commercial-scale kelp cultivation in Europe, with fouling of cultivated kelp fronds presenting a major challenge to the growth and development of the industry. The presence of epibionts decreases productivity and impacts the commercial value of the crop. Several abiotic and biotic factors may influence the occurrence and degree of fouling of wild and cultivated fronds. Using a commercial kelp farm on the SW coast of Ireland, we studied the development of fouling communities on cultivated Alaria esculenta fronds over 2 typical growing seasons. The predictability of community development was assessed by comparing mean occurrence-day. Hypotheses that depth, kelp biomass, position within the farm and the hydrodynamic environment affect the fouling communities were tested using species richness and community composition. Artificial kelp mimics were used to test whether local frond density could affect the fouling communities. Species richness increased over time during both years, and species composition was consistent over years with early successional communities converging into later communities (no significant differences between June 2014 and June 2015 communities, ANOSIM; R = −0.184, p > 0.05). The timing of species occurrences was predictable across years for all shared species. Variations in biomass, depth and position within the farm had no significant effect on species richness and composition. Results from artificial kelp mimics suggest possible hydrodynamic effects. The ability to understand succession and the timing of occurrences of fouling organisms and predict their arrival has significant benefits for the seaweed cultivation industry.

“…Undaria pinnatifida (Harvey) Suringar, called "miyok" in Korean, is a brown alga and a food source for marine animals and humans and is also used as a nursery environment for many marine organisms (Yamanaka andAkiyama 1993, Sohn 1998). In general, the alga is divided into southern and northern types based on morphological features (Okamura 1915, Stuart et al 1999.…”

Twelve morphological characters and the biochemical composition of Undaria pinnatifida f. distans sporophytes growing on the rocky shores of Jindo and Wando and on cultivation ropes in Kijang were measured to determine whether each population could be characterized by morphological features and biochemical composition. The goal of this study was to compare phenotypic variations between populations as they relate to environmental conditions. The sporophytes of the Kijang population were two times longer and 19 times heavier than those at Jindo. Sporophylls of the Jindo U. pinnatifida population were significantly smaller in length, width, frill number, and weight than those at Wando and Kijang. Kijang Undaria plants showed the highest contents of total protein, crude fiber, total amino acids, the amount of essential amino acids, the proportion of total unsaturated fatty acids, and eicosapentaenoic acid. However, the Jindo population showed the greatest content of carbohydrates, lipids, and minerals (Zn and Ca) of the three U. pinnatifida populations. In particular, Zn content of Jindo plants was 30 times greater than that of Kijang plants. Thus, the proximate composition, mineral composition, amino acids, and fatty acids of Undaria pinnatifida plants were distinguishable among the three representative Undaria populations evaluated. These results suggest that morphological and biochemical differences of the three U. pinnatifida populations can be attributed to differences in environmental conditions of their habitats.
