This study aimed to analyze the transcriptome of C. rupestris under Pb2+ stress by using high-throughput sequencing technology, observe the changes of gene expression and metabolic pathway after three and five days under 1.0 and 5.0 mg/L of Pb2+ treatment, and analyze the differentially expressed genes (DEGs) and related functional genes after Pb2+ treatment. Metabolic pathways were revealed through Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis. Results show that DEGs increased significantly with the increase of Pb2+ concentration and stress time. A total of 32 genes were closely related to Pb2+ stress response. GO analysis identified two major transporter proteins, namely, ATP-binding transport protein-related (ABC transporters) and zinc finger CCHC domain containing protein (Zfp) in C. rupestris. Pthr19248, pthr19211, Zfp pthr23002, Zfp p48znf pthr12681, Zfp 294 pthr12389, and Zfp pthr23067 played important roles against Pb2+ toxicity and its absorption in C. rupestris. KEGG pathway analysis suggested that ABCA1, ATM, and ABCD3 were closely related to Pb2+ absorption. Pb2+ stress was mainly involved in metallothionein (MT), plant hormone signal transduction, ABC transporters, and glutathione (GSH) metabolism.

“…Furthermore, polyphosphate granules (Rai et al 1981;Jensen et al 1982) and vacuole (Silverberg 1975) also play an important role in heavy metal sequestration. Under Cd-induced stress, vacuolar compartmentalization provided biosorption in Dunaliella bioculata, Skeletonema costatum, and Cladophora rupestris (Heuillet et al 1986;Nassiri et al 1997;Zhang et al 2019).…”

Short-term effect of cadmium on the motility of three flagellated algal species

et al. 2020

The present work aims to develop a fast and reliable procedure for motility analysis of a short-term effect of heavy metal cadmium on the algal cell response in laboratory conditions. Three unicellular motile species similar in cell length, while differing in the cell wall and the flagellar system are used as model algae. We quantitatively characterise motility in terms of swimming speed and search radius following addition of 1 mg Cd L −1 . Both swimming speed and search radius determined in control algal cultures reflect morphological features of the corresponding flagellated system. After 1 h of cell exposure to a toxic concentration of cadmium, a statistically significant decrease in swimming speed is determined with predominant erratic cell movement on the spot in all examined cultures. After 3 h of cell exposure to cadmium, swimming speed in most of the examined cell cultures recovered close to the control value, indicating quick cell adaptation to elevated cadmium concentration. The results support the implementation of swimming speed and search radius as motility parameters for direct screening of cell physiological state, which is applicable to ecotoxicological studies providing insight into the mechanism of cell adaptation under stress, as well as a better understanding of the spatial distribution of algal cells in aquatic systems.

“…Instead, the majority of studies focus upon the optimisation of process parameters (e.g. pH) utilising biological material of a given species that has been collected from the field (Amro and Abhary, 2019;Arumugam et al, 2020;El-Naggar and Rabei, 2020;Topal et al, 2020;Zhang et al, 2019). The drawback of these studies is that they do not provide any background information relating to the life or nutritional history of the biomass, the environmental conditions in which it was produced, age, time spent washed ashore, if it exhibits any signs of bacterial degradation or presence of epiphytes, or if it has been previously exposed to contaminants during its growth, including heavy metals.…”
