Rye B chromosomes influence the dynamics of histone H3 methylation during microgametogenesis.

González-Sánchez M1, Heredia V, Diez M, Puertas MJ.
Cytogenetic and genome research.Cytogenet Genome Res.2014;143(1-3):189-99. doi: 10.1159/000365422. Epub 2014 Jul 30.
We have studied the trimethylation dynamics of lysines 4 and 27 of histone H3 in rye with and without B chromosomes (Bs) in root tip mitosis, meiosis, and pollen grain mitosis by immunostaining. In root meristems, H3K4me3 immunolabeling was homogeneous along the chromosome arms of the normal complem

Changes in DNA methylation levels and nuclear distribution patterns after microspore reprogramming to embryogenesis in barley.

El-Tantawy AA1, Solís MT, Risueño MC, Testillano PS.
Cytogenetic and genome research.Cytogenet Genome Res.2014;143(1-3):200-8. doi: 10.1159/000365232. Epub 2014 Jul 26.
Under specific stress treatments, the microspore can be induced in vitro to deviate from its gametophytic development and to reprogram towards embryogenesis, becoming a totipotent cell and forming haploid embryos. These can further regenerate homozygous plants for production of new isogenic lines, a

The Arabidopsis general transcription factor TFIIB1 (AtTFIIB1) is required for pollen tube growth and endosperm development.

Zhou JJ1, Liang Y, Niu QK, Chen LQ, Zhang XQ, Ye D.
Journal of experimental botany.J Exp Bot.2013 May;64(8):2205-18. doi: 10.1093/jxb/ert078. Epub 2013 Apr 1.
Pollen tube growth and endosperm development are important for fertilization and seed formation. The genetic mechanism of the processes remains poorly understood. This study reports the functional characterization of AtTFIIB1 in pollen tube growth and endosperm development. AtTFIIB1 shares 86% and 4

マオウ属植物の花粉は減数分裂ののち,小胞子,胚的細胞,造精器細胞,生殖細胞,中心細胞による5回の細胞分裂を経て完成する.分裂はすべて不均等分裂であり,前4個の細胞では,楕円形をなす細胞の長軸の一端へ紡錘体が偏在することがその一因となる,さらに,分裂の不均等性をより増幅するフラグモプラスト(隔膜形成体)の特異な発達様式が明らかとなり,その特徴は,造精器細胞分裂において顕著であった.造精器細胞分裂終期 …

被子植物の花粉発生は, 栄養成長から生殖成長への転換によって形成された花芽の葯内で始まり, 受粉後2個の精細胞が胚のう中の卵細胞ならびに2個の極核をもつ中央細胞と重複受精することによって終わる. この間, 花粉母細胞の減数分裂による半数性（n）細胞（小胞子）の形成, 小胞子の不等（細胞）分裂による雄原細胞と栄養細胞の分化, 花粉管の伸長と一連の劇的な細胞学的変化がみられる. ところが, 花粉母細胞 …
