MeSH headings : Amylopectin / metabolism; Amylose / metabolism; Cotyledon / enzymology; Cotyledon / growth & development; Cotyledon / metabolism; Hypocotyl / enzymology; Hypocotyl / growth & development; Hypocotyl / metabolism; Magnetics; Plant Physiological Phenomena; Plastids; Solanum tuberosum / enzymology; Solanum tuberosum / growth & development; Solanum tuberosum / metabolism; Soybeans / enzymology; Soybeans / growth & development; Soybeans / metabolism; Space Flight; Starch / metabolism; Starch / physiology; Weightlessness; alpha-Amylases / metabolism
TL;DR: The role of ethylene appears to be more important for changes in starch metabolism than microgravity, and the good correlation between the amylose content and delta X/delta rho suggests, that the magnetic susceptibility of starch grains is related to their amylOSE content.

Cytochemical localization of calcium in soybean root cap cells in microgravity

SPACE LIFE SCIENCES: GRAVITY PERCEPTION AND TRANSDUCTION IN PLANTS, FUNGI AND UNICELLULAR ORGANISMS, Vol. 27, pp. 967–972.

By: D. Klymchuk *, C. Brown*, D. Chapman*, T. Vorobyova* & G. Martyn*

MeSH headings : Antimony / pharmacology; Calcium / metabolism; Cell Nucleus / metabolism; Cell Nucleus / ultrastructure; Chemical Precipitation; Cytoplasm / metabolism; Cytoplasm / ultrastructure; Ethylenes / antagonists & inhibitors; Meristem / metabolism; Meristem / ultrastructure; Microscopy, Electron; Plant Root Cap / metabolism; Plant Root Cap / ultrastructure; Plastids / metabolism; Plastids / ultrastructure; Soybeans / metabolism; Soybeans / ultrastructure; Space Flight; Vacuoles / metabolism; Vacuoles / ultrastructure; Weightlessness
TL;DR: The antimonate precipitation technique was used to evaluate the effects of microgravity and ethylene on the cellular and subcellular distribution of free calcium ions in soybean root apices and showed a reduction of precipitate density in the cytoplasm and the nucleus, and an increase in precipitatedensity in the vacuoles of both spaceflight treatments in comparison with ground controls.
