The use of cytoplasm male sterility （CMS） is crucial for three-line hybrid seed production. Two types of CMS have been discovered from Dongxiang wild rice, namely the wild abortion type CMS （CMS-WA） and the Dongxiang wild type CMS （CMS-DW）. In this study, we show the molecular identification of the two types of CMS in Dongxiang wild rice. WA352, which conferred CMS-WA, was not detected in Dongxiang wild iice, implying Dongxiang wild rice does not carry the CMS- WA source. Further analysis of WA352 in DYIA, a CMS-DW line, by PCR amplification and sequencing, revealed two insertion-deletion polymorphisms occurred in CMS-DW compared to WA352 of CMS-WA. It was reported that WA352 was comprised of an unknown origin sequence and partial sequences of three open reading frames （ORFs）, orf284, orf224 and orf288. The 42-bp insertion was located between the two segments of orf224 and orf288, which created a new chimeric ORF, orf216. This new ORF was also detected in CMS-HL. Based on the 9-bp deletion in orf284, a specific mitochon- drial marker of DW-M1 was developed, which could be used to specifically distinguish the DW-type source. Moreover, semi-quantitative RT-PCR analysis preliminarily suggested that both orf216 and orf284 could be considered as candidates for CMS-DW. These findings present a preliminary understanding of CMS-DW at the molecular level.

Reaction of Mo(CO) 6 with p Cl C 6H 4SNa and Et 4NCl·H 2O in CH 3CN afforded a dinuclear molybdenum(0) compound 〔Et 4N〕 2〔Mo 2(CO) 8(SC 6H 4 Cl p ) 2〕 (1). The crystal structure was determined by X ray diffraction. The crystallographic data: C 36 H 48 Cl 2Mo 2N 2O 8S 2, M r = 963.71, monoclinic, P2 1/c, a=9.269(4), b=13.750(3), c=17.466(6) ;β=104.84(3)°; V=2151.8(3)  3; Z=2; D c =1\^49 g/cm 3; F(000)=984; μ=8.3 cm -1 ; Mo Kα radiation ( λ =0.71073); Final R =0.055 and R w =0.065 for 3287 reflections with I>3.0σ(I ). The X ray structure analysis revealed that the Mo 2S 2 core is planar. The geometry around each Mo atom is a distorted octahedron, both of which form an edge sharing bioctahedron. The Mo…Mo distance is 4.014(2) , and this obviously indicates the absence of Mo-Mo bond.
