Endosperm cell remain 1-2 layers in mature seed. 19 A switchover to endosperm dependency occurs around the heart - shaped stage. 20 DNA was successfully extracted from the endosperm of torreya ( Torreya grandis ) seeds, using the modified CTAB process. 21 Endosperm The nutritive tissue that surrounds the embryo in angiosperms. 22 Aleurone layer The outermost protein rich layer of the endosperm grass fruits ( e . g . cereal grains ). 23 In succession, cell layer of suspensor rapidly grew, elongated and down proembryo was carried away cell wall of archegonial base(), then get into corrosion cavity in endosperm. 24 The nucellus is usually degraded and absorbed as the endosperm develops. 25 The latter causes hydrolysis of the starch in the endosperm. 26 The results showed that Abscisic acid (ABA) and ethrel could improve the single cell area of wheat starchy endosperm, thus affect the quality and grain weight of wheat. 27 A comparison of the caryopsis development, rice quality characteristics and the size, pattern, structure of the endosperm amyloplasts (starch granules) in the two indica rice varieties was made. 28 The results are as follows: the formation and development of the embryo and endosperm is in accord with the typical graminaceous plants. 29 These above-mentioned three characteristics of fruits, number of vitta, evolvement status of lateral rib and endosperm form,[] may serve as reference in interspecies relationship study. 30 The embryo development went through three stages: proembryo, embryo differentiation and embryo maturation, and the endosperm experienced a free nuclear stage. 31 In peas there is an initial deposition of materials in the endosperm following anthesis. 32 In flowering plants , for instance, the early stages of endosperm development are often acellular. 33 Pasta:Any of several starchy food pastes (pasta alimentaria) made from semolina, the purified middlings (endosperm) of a hard wheat called durum. 34 The amyloplast in rice endosperm was a plural one, that is, an amyloplast contained many starch grains, While an amyloplast in wheat contained only one starch grain. 35 When the free nuclei of the endosperm were 16 or 32, the nucellar embryo initial (s) originated from the nucellar cells near the micropylar end of the embryo sac. 36 Fig. 3 A model for the biosynthesis of amylopectin cluster in rice endosperm. 37 Quantative trait loci(QTL) were identified and its effects were analysized by using triploid endosperm genetic model and interval mapping. 38 Endosperm formation is nuclear type and the endosperm forms chalazal haustorium. 39 Heat - denatured wheat endosperm prevented the growth of an embryo implanted on it. 40 Lots of starch grains in nucellar cells and integumentary cells surrounding endosperm haustoria decreased and disappeared with the development of endosperm haustoria. 41 The plasmalemma in endosperm cells of rice showed invagination with developing and differentiating. The ultrastructure and phosphatase activity cytochemistry of these invaginations were studied. 42 Seminal majority, dinky, seed coat has fossa opening , endosperm flesh is qualitative. 43 The caryopsis growth and endosperm development of colored rice were basically the same as conventional rice, with the exception in its anthocyanidin accumulation in the pericarp. 44 In grasses, the starch in the endosperm is broken down by enzymes synthesized in the aleurone layer in response to gibberellic acid from the embryo. 45 Endosperm starch content of sweet maize was lower than normal corn notably. 46 The results showed that the lipase of rice distribute in the plumule and the scutum, not in the endosperm, It consists of several kinds of isoenzyme. 47 Endosperm is the main part of rice seed. The development of endosperm is closely related with the productive property of rice. 48 Starch granule of powder endosperm arranged loosely and showed a polyhedron shape. 49 The endosperm structure of the soft wheat was looser than that of the hard wheat. 50 The contents of soluble sugar, soluble protein and fat declined slowly, but the free amino acids and starch increased in the endosperm of Tilia miqueliana seeds without treatment. 51 The guar seeds are dehusked, milled and screened to obtain the ground endosperm i . e . guar gum. 52 Long patent flours contain a high proportion of the endosperm; short patent flours contain relatively less, with a higher of the endosperm left as clear flour. 53 Anatomy and histochemistry of the seeds of Cautleya gracilis were studied in this paper. The results show that the seed of Cautleya gracilis comprises seed coat, perisperm, endosperm and embryo. 54 The results of the anatomy and histochemistry of the seeds of Roscoea purpurea show that the seed consists of aril, seed coat, perisperm, endosperm and embryo. 55 Admittedly, much information on the chemical nature of other endosperm tissues, not included here, is available. 56 The chalazal parts of the endosperm containing free nuclei forms several lobes. 57 It accumulates in the amyloplasta of the endosperm cells during grain filling. 58 The concept of antipodal embryo and the relationship of antipodal apogamy with endosperm are discussed.sentence dictionary 59 Amyloplast had many ways of genesis and patterns of proliferation in endosperm cell of rice. 60 The other male gamete fuses with the secondary nucleus, forming the primary endosperm nucleus. 61 The later the timing of panicle fertilizer application was, the higher the crude protein content and glutelin content of rice endosperm was and the lower the prolamin content of rice endosperm was. 62 The starchy endosperm of wheat underwent programmed cell death ( PCD ) during its development. 63 The endosperm, which is derived from two polar nuclei fusing with one sperm, is a triploid tissue whose genetic constitution is more complex than common diploid tissue. 64 The first periclinal wall of endosperm cell arises from cell plate which is the result of normal cytokinesis. 65 With the embryo development, most of the endosperm degenerated, and the cells near chalaza entered the chalaza, digested it and further nourished the embryo. 66 Vacuolate inclusions are present in the fat globules of the endosperm of young seeds. 67 The seed has very big embryo but without endosperm, often provide aril. |
