Abstract

The extensive genetic resources of Chlamydomonas has led to its widespread use as a model system for understanding fundamental processes in plant cells, including rates of cell division potentially modulated through polyamines. Putrescine was the major polyamine in both free (88%) and membrane-bound fractions (93%) while norspermidine was the next most abundant in these fractions accounting for 11% and 6%, respectively. Low levels of diaminopropane, spermidine and spermine were also observed although no cadaverine or norspermine were detected. Ornithine decarboxylase (ODC, EC 4.1.1.17) activity was almost five times higher than arginine decarboxylase (ADC, EC 4.1.1.19) and is the major route of putrescine synthesis. The fluoride analogue of ornithine (α-DFMO) inhibited membrane associated ODC activity whilst simultaneously stimulating cell division in a dose dependent manner. Following exposure to α-DFMO the putrescine content in the cells declined while the norspermidine content increased over two fold. Addition of norspermidine to cultures stimulated cell division mimicking the effects observed using DFMO and also reversed the inhibitory effects of cyclohexylamine on growth. The results reveal that ODC is the major route to polyamine formation in the Chlamydomonas CC-406 cell-wall mutant, in contrast to the preferential ADC route reported for Chlorella vulgaris, suggesting that significant species differences exist in biosynthetic pathways which modulate endogenous polyamine levels in green algae.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Optimal growth of algae may require supplementation with a wide range of micronutrients such as those found in Hutner's trace elements solution.

    “optimal growth may require supplementation with a wide range of micronutrients such as those found in Hutner's trace elements solution”

    From Key Targets for Improving Algal Biofuel Production (2021) · cites this paper as [25]

    The cultivation methods (accepted manuscript, p. 5) say that Chlamydomonas was grown in TAP medium containing Hutner’s trace elements. The paper does not establish that those elements are required for optimal growth, or assess a wide range of micronutrients. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
