“…As one of the original species in green tide outbreak in Yellow Sea of China since 2008, U . flexuosa has attracted global attention for its fast growth if given appropriate nutrient supply, with maximum growth rate of 73% d -1 at room temperature under light intensity of 70 μmol·m -2 ·s -1 [ 3 ]. On the other hand, culturists in Brazilian are interested in the sulfated polysaccharide ulvan which triggers plant defenses against disease and can be obtained from U .…”

Ulva flexuosa, one kind of green tide algae, has outbroken in the Yellow Sea of China during the past ten years. In the present study, we sequenced the chloroplast genome of U. flexuosa followed by annotation and comparative analysis. It indicated that the chloroplast genomes had high conservation among Ulva spp., and high rearrangement outside them. Though U. flexuosa was closer to U. linza than U. fasciata in phylogenetic tree, the average Ka/Ks between U. flexuosa and U. linza assessed by 67 protein-coding genes was higher than those between U. flexuosa and other species in Ulva spp., due to the variation of psbZ, psbM and ycf20. Our results laid the foundation for the future studies on the evolution of chloroplast genomes of Ulva, as well as the molecular identification of U. flexuosa varieties.

SUMMARY Ulva prolifera is a green‐tide‐forming macroalga dominating the green tides in the Yellow Sea from 2007 to 2019. The exponential growth of U. prolifera, and the correlating accumulation of biomass, rely heavily on its carbon fixation capability. Despite the importance of carbon fixation in algal growth, to date none of the genes involved in carbon fixation have undergone molecular characterization in U. prolifera. This study used Rapid Amplification of cDNA Ends (RACE) to characterize one full‐length carbonic anhydrase (CA) gene of U. prolifera (UpαCA1). An activity assay showed that UpαCA1 was an active CA. Real‐time quantitative PCR results showed that temperature, irradiance, salinity and pH could influence the transcriptional level of UpαCA1, indicating that UpαCA1 was sensitive to varying environmental factors. The results of this study provided further insights into our understanding of the influence of environmental factors on carbon fixation in U. prolifera and its subsequent role in the formation of green tides.

“…In recent years, during June to July, sea surface temperature (SST) of the Yellow Sea ranged from 20 to 27°C [10], which is the optimal temperature for the growth of U . prolifera [31]. However, in 2017, extreme high temperature (> 30°C, Fig 3) lasted for more than 1 month, resulting in the slow expansion of the blooms.…”

“…U . prolifera can tolerate high levels of irradiance, and is able to grow under levels as high as 600 μmol m -2 s -1 [31]. The surface irradiance of the entire Yellow Sea can be maintained at over 1,000 μmol m -2 s -1 which was difficult to be realized under laboratory conditions [33].…”

Annual patterns of macroalgal blooms in the Yellow Sea during 2007–2017

The world’s largest macroalgal blooms caused by Ulva prolifera have occurred in the Yellow Sea for 11 consecutive years. The area covered by blooms has been approximately 500 km2 in previous years, while in 2017, the maximum area decreased significantly to 312 km2. In this study, we concluded that species competition between Ulva and Sargassum (fast rise of the golden tides), extreme high sea surface temperature and harvest for floating Ulva macroalgae were the three critical factors influencing the sharp reduction in covered area for blooms in 2017. In addition, analysis of annual variations of Pyropia aquaculture area in the Southern Yellow Sea over the past two decades revealed that a great expansion in “Sansha” regions was mainly responsible for the initial blooms in 2007, and that this expansion supported the great biomass of the blooms in following years. Based on these findings, we suggest comprehensive utilization of the macroalgal blooms is a feasible way to control them.
