Example Sentences:

(6) The endosperm cells of the American basswood Tilia americana are favorable experimental material for investigating the birefringence of living plant spindles and anaphase movement of chromosomes.
(7) It was found that these groups represent varying amounts of transcripts that range from 2 to 20% of the total endosperm mRNA population.
(8) The enzymes are likely to function in the depolymerization of cell wall arabinoxylans during mobilization of the starchy endosperm.
(9) A 216 bp promoter fragment of the 19 kDa protein zein gene pMS1, containing the CCAAT and TATA boxes, was analysed by a variety of techniques for in vitro interactions with nuclear proteins from endosperm tissue.
(10) Serum antibodies from the maize-fed mice, immunized with either alpha-zein or maize glutelin, showed even labelling of the major maize endosperm proteins while antibodies from mice on the wheat diet showed strong labelling of the Mr 27,000 and 58,000 bands.
(11) The physical parameters tested were: test weight (TW), endosperm texture (TE), pearling index (IP), 1000 kernel wt (W 1000), infrared reflectance (NIR) and color (Ref).
(12) The objectives of this paper were: to classify 24 modern hybrids of early corn according to endosperm texture and to determine their physical and chemical properties and their relationships.
(13) Thionin concentration in mature endosperm of barley cv.
(14) Ultrastructural studies showed that gamma-zein occurs in high concentrations in the first few subaleurone cells of nonmodified endosperms, but high concentrations of gamma-zein occur in the subaleurone and central endosperm cells of modified opaque-2 mutants.
(15) Glb2 transcripts are found only in the developing embryo, and not in endosperm, seedling, or unfertilized ears.

(17) The kinetics of [35S]methionine incorporation into the major organelle fractions of 3-day-old endosperm tissue showed that the endoplasmic reticulum was immediately labelled, whereas a lag period preceded the labelling of mitochondria and glyoxysomes.
(18) DHPS mRNAs complementary to the cDNA were detected in RNA isolated from developing maize endosperm and embryo tissues.

Perisperm
Definition:
(n.) The albumen of a seed, especially that portion which is formed outside of the embryo sac.
Example Sentences:
