aleuronen.

Brit.

/ˈaljᵿrəʊn/, U.S.

/ˈæljəˌroʊn/,

/əˈlʊroʊn/

Forms: 1800s– aleuron, 1800s– aleurone.

Origin: Of multiple origins. Partly a borrowing from French. Partly a borrowing from German. Etymons: French aleurone; German Aleuron.

Etymology: < (i) French aleurone (1856), and its etymon (ii) German Aleuron (T. Hartig 1856, in Bot. Zeitung 14 257) < ancient Greek ἄλευρον flour (usually in plural, ἄλευρα) < the stem of ἀλεῖν to grind ( < the same Indo-European base as Armenian ałal to grind) + -ρον suffix forming nouns (compare earlier ἄλεαρ, ἄλειαρ, plural ἀλέατα, ἀλείατα, also denoting flour).Hartig first described the substance in Bot. Zeitung 13 (1855) 881–2, and subsequently in a later paper in the same issue of that journal (905–6), but used the terms Klebermehl, literally ‘sticky flour’, and Stärkemehl, literally ‘starch flour’, in these papers.

Chiefly Botany.

Protein stored as granules in seeds and other plant storage tissues, esp. in the outermost layer of the endosperm of the seeds of cereals and other grasses. Formerly also: †proteinaceous material found in the ova of certain animals (cf. vitellin n. 1) (obsolete. rare).

ΚΠ

1858 L. Beale Microscope (ed. 2) ii. iv. 157 M. Hartig, in a paper on aleurone,..calls attention to such masses, which are seen in any liniment composed of oil and ammonia.

1879 Pharmaceut. Jrnl. & Trans. 22 Nov. 403/2 The use of aleurone is to act as a reservoir of protein, in the same way as starch and oil globules are reservoirs of hydrocarbons.

1921 C. W. Ballard Elements Veg. Hist. iv. 64 Aleurone is a protein or nitrogenized principle found in many seeds, especially those rich in fixed oil.

1996 Science 6 Sept. 1406/3 In grass seeds, the endosperm contains an epidermis like layer called aleurone, which is an important source of hydrolytic enzymes.

2008 Plant Physiol. 148 908/2 The outermost endosperm cell layer differentiates into aleurone.

Compounds

General attributive, as aleurone cell, aleurone grain, aleurone layer, etc.

ΚΠ

1875 A. W. Bennett & W. T. T. Dyer tr. J. von Sachs Text-bk. Bot. 55 The aleurone grains of oily seeds contain no oil.

1879 New Sydenham Soc. Lexicon Aleuron masses or crystals are found in the vitellus of the ova of fishes and other vertebrata.

1895 L. E. Sayre Man. Org. Materia Med. ii. 70 Aleurone granules are roundish, amorphous masses. Their nature is not very well understood.

1946 Brit. Med. Jrnl. 27 July 132/1 The aleurone layer..in ordinary milling, is separated with the bran and contains about 16% of the total protein of the grain.

1967 New Phytologist 66 27 The major portion of seeds occurs in distinct organelles called aleurone grains or protein bodies.

2009 W. G. Hopkins & N. P. A. Hüner Introd. Plant Physiol. (ed. 4) xxi. 361/1 This approach led to the identification of ABAP1, a protein that is located in the plasma membrane of barley aleurone cells.
