Five hundred and twenty-two isolates of Magnaporthe grisea isolated from rice in 5 Asian countries were characterized for their mating type by crossing them with 4 hermaphroditic isolates(KA3 and TH12: MAT1.1; Guy11 and TH16: MAT1. 2). Among them, 41% were MAT1.1 and 25% were MAT1. 2. The remaining 34% did not produce perithecia with any of the 4 hermaphroditic testers. In Bangladesh, India, Nepal, Vietnam and in most provinces of China, both mating types were present. Only one mating type was found in 3 provinces and 1 city of China. Almost all the isolates had very low fertility, as they were in general female sterile and sometimes also male sterile. Hermaphroditic isolates were recovered from the 5 countries. In these countries, they represented between 13% and 75% of the isolates. In Zhejiang, Guizhou, Guangdong, Hunan, Yunnan and Hubei provinces of China, hermaphroditic isolates represented between 6% and 67%. The genetic diversity of 143 isolates from these countries and provinces, where hermaphroditic isolates had been collected, was analyzed using SCAR markers. Genetic diversity was high and population structure did not resemble classical clonal structure described in most rice growing regions. The existence of sexual reproduction in the field, localization of a center of diversity in China, and migration between countries were discussed in this paper.

In this paper,a novel fault detection scheme for linear process systems using data-based dissipativity theory is *** data-based dissipativity is learned from the available input/output *** of a process is an input/output property,which may not be valid when a fault *** light of this fact,in the proposed approach,the dissipativity of a process is tailored such that it is fault-sensitive,i.e.,no longer valid when faults *** adopting the storage functions and supply rates in the quadratic difference form,the dissipativity conditions are represented as quadratic functions of the input/output trajectories of the process,which captures much more detailed dynamical features compared to traditional *** dissipativity properties are determined offline by solving an optimization problem with linear matrix inequality *** online diagnosis algorithm involves checking of inequalities on input/output trajectories only,which makes the design much *** proposed approach is illustrated using a case study of fault detection of a heat exchanger.

[ Objective] To explore the effects of different seed colors on seed germination and callus induction of Leymus chinensis. [ Method ] According to the color of mature seeds of Leymus chinensis, they were divided three color types, namely, pale yellow, yellow and black. Their seed germination and callus induction were observed. [ Result] The pale yellow Leymus chinensis seeds had higher germination rate （32.5%） and rate of callus induction （28.5%）. Based on the results of the TI＇C method and electrical conductivity, the seed viability was decreased with the deepening seed color. [ Conclusion] The study laid the foundation for establishing highly efficient plant regeneration system of Leymus chinensis.

以一株海洋丝状真菌(Penicillium janthinellum)UV-0S为出发菌株,通过多级紫外线诱变育种后获得几丁质脱乙酰酶(CDA)高产突变株UV-3S,并对该菌株产CDA的发酵特性及其细胞壁几丁质的脱乙酰度(DD)进行研究。结果表明,突变株UV-3S的胞外CDA酶活力为11.05 U/m L,是出发菌株UV-0S的2.1倍。该菌株产胞外CDA的最适初始p H值为9.0,最适无机盐为NaH_2PO_4(11 mmol/L),胶体几丁质最适添加量为0.5%。在此最佳发酵条件下,突变株UV-3S的CDA酶活力最高,为11.83 U/m L,说明CDA是一种诱导酶。细胞壁几丁质的脱乙酰度随真菌生长而增加,且在发酵96 h后脱乙酰度达到最高(90.52%)。
