| 1 | Gene expression profiling under different photoperiod/temperature conditions in a photoperiod-/thermo-sensitive genic male sterile line of rice(Oryza sativa L.)显示文摘Peiai 64S is a photoperiod- and thermo- sensitive genic male sterile (PTSGMS) line of rice, which is male sterile at long day/high temperature and partial fertile at short day/low temperature. A cDNA array representing 3328 unique rice genes was used to profile the gene expression patterns in the young panicles of Peiai 64S under these two condi- tions. The statistical data showed that up to 14.60% of genes exhibited up-or down-regulated expressions in the plants at long day/high temperature compared with plants at short day/low temperature. Only four genes were up-regulated while 482 genes down-regulated. Real-time PCR with all the up-regulated and 9 randomly selected down-regulated genes confirmed the differential expressions detected by the array, indicating that the constructed cDNA array is reliable. These differently expressed genes participated in almost all cell biological responses. Analysis of up- and down-regulated genes revealed distinctive changes between the mRNA abundances of MMK1 and MMK2, both of which are analogs ofMAPK, and significant down-regulation of several transcription factors. It was suggested that changes that occurred in the MAPK signal transduction path- way might disturb the transcription control necessary for morphogenesis of pollens and corresponding phys- iological functions. | GUO Xiaoqin DONG Haitao ZHENG Kangle LUO Hongmei TAN Xuelin FANG Yongqi WANG Yanqin DENG Ye DAI Chengen LOU Yichun SHAO Jing SHI Wenqin ZHAO Dong LI Debao | 2006 | Chinese Science Bulletin2006，51，2： | 2 |

| 3 | Identification of a RAPD marker linked to a blast resistance gene in Oryza sativa L显示文摘Marker-aided selection has received more attention in recent years. This relies on the exploitation of close linkage between molecular markers and target gene(s). We report here a randomly amplified polymorphic DNA (RAID) marker tightly linked to the blast resistance gene Pi-11(t) derived from Hongjiaozhan, which confers the resistante to race ZBI of Pyricularia oryzae Car. | LU Jun,QIAN Huirong,ZHUANG Jieyun,LIN Hongxuan,and ZHENG Kangle CNRRI,Hangzhou 310006,China | 1994 | Chinese Rice Research Newsletter1994，2，4： | 0 |
| 4 | 毛竹的耐铝性研究显示文摘毛竹广泛分布于中国的南方的酸性土壤区域,那些区域是铝毒性的高风险地区。为了对毛竹对铝的抗性的进行评估,本文对相同生长进程下的毛竹和两个水稻栽培品种的种子萌发和根的延长生长进行了对比,并仔细观察了他们在各级不同铝的受力下的物理和生理的损害程度。结果表明:铝浓度增加至500μM时,毛竹种子萌发受到抑制,半致死浓度为2000μM。相比之下,水稻种子萌发并没有受到铝浓度的抑制,甚至在铝浓度为2000μM时。铝积累主要在根尖细胞壁和原生质体治疗时间的延长进入原生质体和/或随着铝浓度的增加,这种现象导致细胞凋亡。竹子的根表皮在2000μM铝浓度时存在显著的退化。总之,毛竹只对低浓度的铝具有抗性。 | Renvi Gui Huanan Leng Shunyao Zhuang Kangle Zheng Wei Fang | 2012 | 世界竹藤通讯2012，，5： | 0 |
| 5 | Effect of anisotropic resistance characteristic on boundary-layer transitional flow显示文摘It is observed that the feather surface exhibits anisotropic resistances for the streamwise and spanwise flows.To obtain a qualitative understanding about the effect of this anisotropic resistance feature of surface on the boundary-layer transitional flow over a flat plate,a simple phenomenological model for the anisotropic resistance is established in this paper.By means of the large eddy simulation(LES)with high-order accurate finite difference method,the numerical investigations are conducted.The numerical results show that with the spanwise resistance hindering the formation of vortexes,the transition from laminar flow to turbulent flow can be delayed,and turbulence is weakened when the flow becomes fully turbulent,which leads to significant drag reduction for the plate.On the contrary,the streamwise resistance renders the flow less stable,which leads to the earlier transition and enhances turbulence in the turbulent region,causing a drag increase for the plate.Thus,it is indicated that a surface with large resistance for spanwise flow and small resistance for streamwise flow can achieve significant drag reduction.The present results highlight the anisotropic resistance characteristic near the feather surface for drag reduction,and shed a light on the study of bird’s efficient flight. | Zheng HONG Zhengyin YE Kangling WU Kun YE | 2022 | Applied Mathematics and Mechanics(English Edition)2022，43，12： | 0 |
| 6 | Multiple splicing types of OsRIX4,an RAD21 homolog in rice (Oryza sativa L.)显示文摘The present paper describes multiple splicing types of OsRIX4,an RAD21 homolog in rice. A type of alternative splicing (AS),distinctive from all five previously known splicing types,was identified in which interior sequences of a constitutive exon could be spliced. Translation of the transcript produced with this AS type was demonstrated at the protein level. Expression of multiple transcripts was organ specific. The expression abundance of transcripts,OsRIX4-4 and OsRIX4-5,was positively correlated with fertility in rice. The splicing type identified in the present study provided the means to further un-derstand and define different mRNA splicing types in plants and suggested that post-transcription processing of mRNA and its regulation mechanism are complex. | DONG HaiTaoi GUO XiaoQin PEI YanXi DAI ChengEn FANG YongQi TU QiChao ZHUANG JieYun ZHAO Dong ZHENG KangLe LI DeBao | 2007 | Chinese Science Bulletin2007，52，11： | 0 |
