“…Phytoplankton are the primary producers in the aquatic food web and play essential roles in the biotic water environment (Zhao et al, 2022). Most phytoplankton are single‐celled photosynthetic organisms that can achieve a rapid increase in number after continuous cell cycles by cell proliferation and division in suitable environments (Dewitte & Murray, 2003).…”

“…Therefore, understanding the cell cycle and regulation mechanism to achieve the appropriate biomass is essential for maintaining aquatic ecosystem health. Zhao et al (2022) summarized the current information about the eukaryotic phytoplankton cell cycle and the environmental factors that affect it. They also introduced the research methods for the phytoplankton cell cycle, highlighted the progress in understanding the molecular mechanisms of phytoplankton cell cycle regulation, and discussed future directions for phytoplankton cell cycle research.…”

Young scientists are the most active force driving scientific advancement and technological innovation. Nonetheless, young scholars also face challenges such as heavy workloads, shortage of research-focused hours, high competition in grant application, and securing an academic job, among others. Mentorship from supervisors and senior peers is important to encourage and reassure the scientific endeavors of young scholars. Favorable policies and activities arranged by public agencies or academic societies are also essential for nurturing and promoting the successful establishment of young scholars. Chinese young scientists have been making great contributions to aquaculture research and applications. The China Society of Fisheries organized the Annual Conference of Youth Scholars in Shanghai on October 18, 2021. There were over 300 attendees to this meeting, which covered the topics of aquaculture techniques and equipment, biotechnologies and breeding, nutrition and feeds, diseases and quality security, aquaculture resources and conservation, and aquaculture economy and management. Here, we summarize some representative work by the attendees who were selected for this special issue, which partially reflects the recent research focus on young aquaculture scientists in China.The healthy and sustainable development of aquaculture depends heavily on research on nutritional feeds in terms of precise nutritional requirements of aquatic animals. The largemouth bass, Micropterus salmoides, characterized by its fast growth and delicious taste, is currently a major species of freshwater aquaculture in China. According to the China Fishery Statistical Yearbook report, the total production of farmed largemouth bass in 2020 was more than 619,500 tons, and the national demand for this fish is also increasing yearly (China Fishery Yearbook, 2021). To date, the requirement of each vitamin of the largemouth bass has its own specific and irreplaceable function, so it is necessary to investigate the optimal level of usage one by one. The requirement for fat-soluble vitamins, including vitamins

The cell cycle is the fundamental cellular process of eukaryotes. Although cell-cycle-related genes have been identified in microalgae, their cell cycle progression differs from species to species. Cell enlargement in microalgae is an essential biological trait. At the same time, there are various causes of cell enlargement, such as environmental factors, especially gene mutations. In this study, we first determined the phenotypic and biochemical characteristics of a previously obtained enlarged-cell-size mutant of Nannochloropsis oceanica, which was designated ECS. Whole-genome sequencing analysis of the insertion sites of ECS indicated that the insertion fragment is integrated inside the 5′-UTR of U/P-type cyclin CYCU;1 and significantly decreases the gene expression of this cyclin. In addition, the transcriptome showed that CYCU;1 is a highly expressed cyclin. Furthermore, cell cycle analysis and RT-qPCR of cell-cycle-related genes showed that ECS maintains a high proportion of 4C cells and a low proportion of 1C cells, and the expression level of CYCU;1 in wild-type (WT) cells is significantly increased at the end of the light phase and the beginning of the dark phase. This means that CYCU;1 is involved in cell division in the dark phase. Our results explain the reason for the larger ECS size. Mutation of CYCU;1 leads to the failure of ECS to fully complete cell division in the dark phase, resulting in an enlargement of the cell size and a decrease in cell density, which is helpful to understand the function of CYCU;1 in the Nannochloropsis cell cycle.
