Nuclei were pelleted at 800 g for 2–4 min. Nuclei were resuspended in buffer B (2.5% Ficoll 400, 0.5 M sorbitol, 0.008% spermidine, 50% glycerol, and 1 mM DTT), using 1–2 ml per 200 ml of original culture volume. The CHSB Chlamydomonas telomere-specific oligonucleotide probe (Fulneckova et al, 2013) (5′-GTTTTAGGGTTTTAGGGTTTTAGGGTTTTAG-3′, Table S1) was 32P-labeled at the 5′ terminus with ATP (γ-32P) by the T4 polynucleotide kinase (New England Biolabs). 201410 chlamydomonas.png 400 × 375; 20 KB. Life Science Alliance is registered as a trademark in the U.S. Patent and Trade Mark Office and in the European Union Intellectual Property Office. The gel was then washed three times for 30 min at room temperature with 0.25× SSC and imaged as for Southern blots. Reactions of total volume of 110 μl were carried out in 1× MN buffer using 60 μl of sample and different amounts of MNase units (Fermentas). Published 3 June 2019. For loading controls, the gel was then transferred in denaturing conditions on a charged nylon membrane and hybridized again with the same probes. Scientific name i: Chlamydomonas reinhardtii CC3269: Taxonomy navigation › Chlamydomonas reinhardtii. Indeed, the two Chlamydomonas species cluster together with V. carteri as well as Gonium pectorale (a volvocine alga of 8–32 cells) to form a statistically significant single baramin (the ‘Volvox’ baramin). 2 μg of gDNA was digested in 300 μl with a cocktail of six restriction enzymes (PstI, BamHI, MnlI, FokI, TaqI, and MspI; 20 units each). The end-labeled telomeres were then amplified with the primers 169M (poly-G–containing primer) and oT1090 targeting the subtelomere/telomere junction common to 10 telomeres of eight chromosomes (Table S1). Digestion products were isopropanol precipitated, resuspended in loading buffer (gel loading dye, Purple 6X, New England Biolabs) and resolved on a 1.5% agarose gel for 4 h at 150 V. The gel was then soaked in a denaturation bath (0.4 M NaOH and 1 M NaCl) for 20 min and transferred overnight by capillarity to a charged nylon membrane (Hybond XL; GE Healthcare). Chlamydomonas, a genus of unicellular photosynthetic flagellates, is an important model for studies of such fundamental processes as photosynthesis, motility, responses to stimuli such as light, and cell-cell recognition.C. 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, … Telomere length distribution is stable under various growth conditions. DNA was pelleted by centrifugation for 10 min at maximal speed. Chlamydomonas species can become so abundant as to colour fresh water green, and one species, C. nivalis, contains a red pigment known as hematochrome, which sometimes imparts a red colour to melting snow. Chlamydomonas is a genus of green algae consisting of about 325 species all unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as "snow algae". For specific chromosome arms, we used subtelomeric oligonucleotides 1R: 5′-TACTTGTGTGTGCTGTGCGT-3′, 9R: 5′-ACAGCACAATACAGTATATA-3′, and 10R: 5′-AACGTCCTCGTGAGACCACC-3′ (Table S1).
