  polymerization (ROMP). One-pot copolymerization of an ω-norbornenyl macromonomer and a discrete norbornenyl comonomer (diluent) provides opportunities to control the backbone sequence and therefore the side chain distribution. Toward sequence control, the homopolymerization kinetics of 23 diluents were studied, representing diverse variations in the stereochemistry, anchor groups, and substituents. These

  接枝密度和接枝分布影响聚合物的链尺寸和物理性能。然而，实现对这些结构参数的精确控制提出了长期的综合挑战。在本报告中，我们介绍了一种通过接枝开环复分解聚合（ROMP）来合成具有定制结构的聚合物的通用策略。ω-降冰片烯大分子单体和离散的降冰片烯基共聚单体（稀释剂）的一锅共聚提供了控制主链序列并因此控制侧链分布的机会。为了控制序列，研究了23种稀释剂的均聚动力学，这些动力学代表了立体化学，锚定基团和取代基的各种变化。这些修饰将均聚速率常数调整到2个数量级以上（0。–1 s –1 < k homo <82 M –1 s –1）。通过互补的机理和密度泛函理论（DFT）研究确定并阐明了速率趋势。在此基础上，通过将选定的稀释剂与聚（d，l-丙交酯）（PLA），聚二甲基硅氧烷（PDMS）或聚苯乙烯（PS）大分子单体。交叉传播速率常数是根据Mayo-Lewis终端模型通过瞬时共聚单体浓度的非线性最小二乘拟合

  PCR amplification and protein analysis of pinA and pinB, the two components of friabilin, a marker protein for grain softness, were carried out in one hundred varieties from India and forty varieties from Kansas State, USA. Glycine to serine change in pinB or null mutation in pinA (absence of gene) has been reported linked with grain hardness. Here we report that majority of Kansas State hard wheats possess glycine to serine mutation in pinB and few have null mutation in pinA. In contrast, majority of varieties released in India are hard and have null mutation in pinA. There are some exceptions where some hard wheats in India do not exhibit either null mutation in pinA or glycine to serine change in pinB. There might be some additional mutations that are to be characterised in elucidating the molecular basis of hardness for usage in genetic engineering. PinA and pinB genes have been assigned on the distal part of 5D short arm using deletion lines of chinese spring wheat where hardness gene Ha is reported to be present.
