Re b). A small number of cells in culture are always nonviable and possibly dying by PCD and we noted that eight.99 of the untreated manage cells had been FITCand PI2 (I). In contrast, 26.4 of the heat treated (II) underwent PCD.

Culture absorbances and cell counts are for two strains of C. reinhardtii (CC25 and UTEX89) and two other species C. moewusii and C. PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/24367704 debaryana. PCD supernatant was obtained from C. reinhardtii CC25 cultures and supplemented with TAP medium ( : 2). The fitness effects of PCD supernatant were determined spectrophotometrically (absorbance at 665 nm) and by direct cell counts (typical of 4 readings). Supernatant from an untreated (nonPCD) C. reinhardtii CC25 culture was made use of as the control. PCD supernatant had a useful impact on the development of other folks of your very same species and strain based on (a) a statistically substantial difference in absorbances ( p 0.03) and (b) an apparent, albeit not statistically considerable, trend in count comparisons ( p 0.39), the latter possibly due to the relatively little sample size. Unexpectedly, PCD supernatant from C. reinhardtii CC25 inhibited the development of two other species C. moewusii and C. debaryana for 
both absorbance ( p 0.02 in both species) and count comparisons p 0.03 and p 0.02, respectively (c ). The effect on the identical species, distinct strain was not important (absorbances p 0.30; counts p 0.7, g,h). Error bars are s.d. (n 4).as a constructive handle. Additionally, the fitness effects of PCD supplies released by one particular strain (C. reinhardtii strain CC25) on an additional strain C. reinhardtii UTEX89 and two other species (C. moewusii UTEX9 and C. debaryana UTEX344) had been examined. Development dynamics have been atypical due to the comparatively nutrientdepleted media (PCD supernatant obtained following days). The effect of PCD on development of your similar species was good (figure 2a,b), consistent with prior reports [5,]. Unexpectedly, PCD supernatant from C. reinhardtii CC25 inhibited the growth of two other species, C. moewusii (figure 2c,d) and C. debaryana (figure 2e,f ). Following a short initial overlap for 3 days, the curves separated and remained so for the duration on the experiments. The growth curve comparison for any unique strain (UTEX89) was not significant (figure 2g,h). The further con.
