The cells were then thawed at room temperature and 5 ml of preheated buffer AP1 with RNase (QIAGEN DNA Plant Maxi Kit) was added and cells lysed at 65°C for 2 h. After lysis, gDNA was extracted according to the manufacturer's protocol (QIAGEN DNA Plant Maxi Kit). The unicellular green alga C. reinhardtii is amenable to a diversity of genetic and molecular manipulations. Average telomere length was assessed using ImageJ 1.49v (NIH) by measuring the peak of the telomere length distribution signal. Despite UV-C sharing these effects with UV-A/B but at much lower dosages, UV-C sensing and signal mechanisms are still mostly unknown. For sequencing, PCR products were ligated for 1 h at 16°C in a pDrive plasmid. Four Chlamydomonas reinhardtii mutants lacking carotenoids have been described previously: lts1-30 (C hemerilova 1978), fn68 (F oster et al.

The pellet was washed with 70% ethanol, dried, and resuspended in 25 μl H2O. 6× loading dye (6 μl) was added prior loading onto 1.5% agarose gel. 95 (S ager and Z alokar 1958).The fn68 mutant was used to show that a rhodopsin photoreceptor controls the phototactic response in Chlamydomonas and that retinal, a derivative of carotenoids, … We thank the Chlamydomonas Mutant Library Group at Princeton University, the Carnegie Institution for Science, and the Chlamydomonas Resource Center at the University of Minnesota for providing the indexed Chlamydomonas insertional mutants. Using a paintbrush, the pellet was gently resuspended in fresh buffer A without Triton X-100. Triton X-100 was first diluted in 10 ml of buffer A per liter of culture and subsequently added drop wise to the cells while swirling them gently, to a final concentration of 0.5%. 1995).The mt + and mt − versions of this locus segregate 2:2 at meiosis, but early genetic analysis documented … The unicellular alga Chlamydomonas reinhardtii is a classical reference organism for studying photosynthesis, chloroplast biology, cell cycle control, and cilia structure and function. PETRA membrane was also hybridized with [32P]ATP-labeled 1-kb ladder (Thermo Fisher Scientific). The GCM software was run by the author to fit three baramins (figure 2). Aqueous phase was precipitated by adding 42 μl of 3 M NaOAc and 840 μl of 96% ethanol. Algae in this genus have a cell wall, a chloroplast, an "eye" that perceives light, and two anterior flagella with which they can swim using a breast-stroke type motion. Related to, PCR verification of insertion mutants tel-m1 and tel-m2. Thus, we have described and integrated the proteometabolomic and physiological changes occurring in Chlamydomonas reinhardtii… Samples were then run in a 1× Tris-borate EDTA (TBE) 0.75% agarose gel in 1× TBE buffer for 18 h at 20 V. The gel was then dried and hybridized overnight at 37°C with radioactively labeled probes (oT0958, G-probe and oT0959, C-probe, Table S1) in hybridization buffer (5× SSC, 5 μM inorganic pyrophosphate, 1 mM Na2HPO4, 5× Denhardt’s solution, 40 nM ATP, and 20 μg/ml salmon sperm DNA). Thank you for your interest in spreading the word on Life Science Alliance. The gel was then washed three times for 30 min at room temperature with 0.25× SSC and imaged as for Southern blots. PCR reactions (40 μl) contained the end-labeled DNA, 200 μM of dNTPs, primers at 0.5 μM for oT1090 and 0.75 μM for 169M, 1× Taq Mg-free buffer (NEB), and 2.5 U of standard Taq polymerase (NEB).
