Abstract (English)

Gravitational impact significantly affects plant development, influencing cellular composition and growth direction. Hypergravity, defined as gravitational force exceeding Earth's typical 1 g, has been the subject of extensive research concerning its effects on plant physiology, biochemical composition, and growth and development. This systematic review synthesizes current knowledge on how plants adapt and respond to hypergravity. Uniquely, this review consolidates findings across diverse plant species, utilizing the Publish or Perish automation tool to extract relevant articles from databases including PubMed, Google Scholar, Scopus, Semantic Scholar, and Crossref, with articles filtered and assessed using Rayyan per PRISMA guidelines. Key findings indicate that hypergravity inhibits elongation growth while promoting lateral expansion, alters cellular structure by increasing lignin deposition and modifying microtubules, affects gene expression, disrupts calcium levels, decreases cell wall extensibility, enhances polysaccharide content, and influences photosynthesis, starch turnover, and auxin accumulation in various plant species. Moreover, hypergravity also inhibits seed production and pollen tube growth in some species by disrupting the glyoxylate cycle, while in others, it increases germination or has minimal effects. This systematic review highlights the effects of hypergravity on plant physiology, morphology, and biochemistry, both demonstrating adaptive benefits like structural support and stress tolerance and demonstrating disadvantages like growth inhibition and reproduction decline, and also highlighting the importance of prudent utilization of automation equipment, enhanced species studies, and technological advancement to promote both space agriculture and farm sustainability on Earth.
