Genome-Wide Analysis of the Sus Gene Family in Cotton

Journal of Integrative Plant Biology 2013年第7期55卷 643-653页

作者： Changsong Zou Cairui Lu Haihong Shang Xinrui Jing Hailiang Cheng Youping Zhang guoli song State Key Laboratory of Cotton Biology Institute of Cotton Researchthe Chinese Academy of Agricultural Sciences

Sucrose synthase （Sus） is a key enzyme in plant sucrose metabolism. In cotton, Sus （EC 2.***.1.13） is the main enzyme that degrades sucrose imported into cotton fibers from the phloem of the seed coat. This study demonstrated that the genomes of Gossypium arboreum L., G. raimondii Ulbr., and G. hirsutum L., contained 8, 8, and 15 Sus genes, respectively. Their structural organizations, phylogenetic relationships, and expression profiles were characterized. Comparisons of genomic and coding sequences identified multiple introns, the number and positions of which were highly conserved between diploid and allotetraploid cotton species. Most of the phylogenetic clades contained sequences from all three species, suggesting that the Sus genes of tetraploid G. hirsutum derived from those of its diploid ancestors. One Sus group （Sus I） underwent expansion during cotton evolution. Expression analyses indicated that most Sus genes were differentially expressed in various tissues and had development-dependent expression profiles in cotton fiber cells. Members of the same orthologous group had very similar expression patterns in all three species. These results provide new insights into the evolution of the cotton Sus gene family, and insight into its members＇ physiological functions during fiber growth and development.

Analysis on spatial difference of ocean ambient noise spectrum in the northern South China Sea

Chinese Journal of Acoustics 2019年第1期38卷 49-61页

作者： song guoli GUO Xinyi MA Li ZHANG Qianchu Key Laboratory of Underwater Acoustic Environment CAS Institute of Acoustics Chinese Academy of Sciences University of Chinese Academy of Sciences

To study the spatial difference of ocean ambient noise in offshore China and reveal its generation mechanism, the difference between the noise level(NL) of two stations is compared based on long-term observation data collected in the same season. Considering the influence of underwater acoustic channels and the characteristics of noise sources, the transmission loss level(TL) from the port ship noise sources to the measuring station is analyzed and it shows a strong correlation between the transmission loss difference(TLD) and noise level difference(NLD) at the band of 50-500 Hz. At the same time, the analysis of ship noise source level(SL) presents a difference about 20 dB between the two ports, corresponding to the variation of the ship density before and during the fishing moratorium. The results prove that the ambient noise is closely related to ship noise sources at this frequency band, and the noise difference between the two stations results from the transmission loss and the ship noise sources.

Uniqueness of the Gossypium mustelinum Genome Revealed by GISH and 45S rDNA FISH

引用

Journal of Integrative Plant Biology 2013年第7期55卷 654-662页

作者： Qiong Wu Fang Liu Shaohui Li guoli song Chunying Wang Xiangdi Zhang Yuhong Wang David Stelly Kunbo Wang Cotton Research Institute the Chinese Academy of Agricultural Sciences/National Key Laboratory of Cotton Biology Haikou Experimental Station Chinese Academy of Tropical Agricultural Sciences Department of Soil and Crop Sciences Texas A&M UniversityCollege Station

Gossypium mustelinum （（AD）4） is one of five disomic species in Gossypium. Three 45S ribosomal DNA （rDNA） loci were detected in （AD）4 with 45S rDNA as probe, and three pairs of brighter signals were detected with genomic DNA （gDNA） of Gossypium D genome species as probes. The size and the location of these brighter signals were the same as those detected with 45S rDNA as probe, and were named GISH-NOR. One of them was super-major, which accounted for the fact that about one-half of its chromosome at metaphase was located at chromosome 3, and other two were minor and located at chromosomes 5 and 9, respectively. All GISH-NORs were located in A sub-genome chromosomes, separate from the other four allopolyploid cotton species. GISH-NOR were detected with D genome species as probe, but not A. The greatly abnormal sizes and sites of （AD）4 NORs or GISH-NORs indicate a possible mechanism for 45S rDNA diversification following （AD）4 speciation. Comparisons of GISH intensities and GISH-NOR production with gDNA probes between A and D genomes show that the better relationship of （AD）4 is with A genome. The shortest two chromosomes of A sub-genome of G. mustelinum were shorter than the longest chromosome of D sub-genome chromosomes. Therefore, the longest 13 chromosomes of tetraploid cotton being classified as A sub-genome, while the shorter 13 chromosomes being classified as D sub-genome in traditional cytogenetic and karyotype analyses may not be entirely correct.
