Abstract

Nitrogen deficiency and drought stress are among the major stresses faced by plants with negative consequence on crop production. The use of plant biostimulants is a very promising application in agriculture to improve crop yield, but especially to prevent the effect of abiotic stresses. Algae-derived biostimulants represent an efficient tool to stimulate the root development: while macroalgae have already been widely adopted as a source of biostimulants to improve plants growth and resilience, far less information is available for microalgae. The objective of this work is to investigate the stimulant ability on maize roots of two green algae species, Chlamydomonas reinhardtii and Chlorella sorokiniana, being respectively the model organism for Chlorophyta and one of the most promising species for microalgae cultivation at industrial scale. The results obtained demonstrate that both C. reinhardtii and C. sorokiniana cells promoted the development of maize root system compared to the untreated negative control. C. sorokiniana specifically increased the number of secondary roots, while improved micro-nutrients accumulation on roots and shoots was measured in the case of C. reinhardtii treated plants. When these microalgae-derived biostimulants were applied on plants grown in stress conditions as nitrogen deficiency, improved development of the root system was measured in the case of plants treated with C. sorokiniana biomass. Microalgae cultivation for biostimulant production can thus be considered as a bio-based process providing solutions for improving plant resilience toward stress conditions.

  • C. sorokiniana stimulated the maize root system in hydroponic conditions, compared to the untreated control, by increasing root area and root volume, total root length and the number of secondary roots; moreover, C. sorokiniana improved the development of the root system in nitrogen deficiency conditions.

    “C. sorokiniana stimulated the maize root system in hydroponic conditions, compared to the untreated control, by increasing root area and root volume, total root length and the number of secondary roots; moreover, C. sorokiniana improved the development of the root system in nitrogen deficiency conditions [85].”
  • Escalating wastewater production from domestic and industrial sources is driving a pressing need for innovative wastewater treatment processes.

    “This escalating production of wastewater from both domestic and industrial sources is driving a pressing need for innovative wastewater treatment processes, spurred by concerns over water resource crises and environmental pollution [85].”

    From Emerging Applications of Chlorella sp. and Spirulina (Arthrospira) sp. (2023) · cites this paper as [85]

    The Introduction mentions microalgae being used in wastewater bioremediation, but does not discuss increasing wastewater production from domestic or industrial sources or a resulting need for new treatment processes. Searches for those terms found no supporting passage in our copy; the paper focuses on microalgae as maize biostimulants. No page number was available for the indexed passages. (LLM, conf=0.76)

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.
