Sexual reproduction first appeared in unicellular protists and has continued to be an essential biological process in almost all *** protists, which contain both germline and somatic genomes within a single cell, have evolved a special form of sexual reproduction called conjugation that involves mitosis, meiosis, fertilization, nuclear differentiation, genome rearrangement, and the development of unique cellular structures. The molecular basis and mechanisms of conjugation vary dramatically among ciliates, and many details of the process and its regulation are still largely unknown. In order to better comprehend these processes and mechanisms from an evolutionary perspective, this study provides the first comprehensive overview of the transcriptome and proteome profiles during the entire life cycle of the newly-established marine model ciliate Euplotes vannus. Transcriptome analyses from 14 life cycle stages(three vegetative stages and 11 sexual stages) revealed over 26,000 genes that are specifically expressed at different stages, many of which are related to DNA replication,transcription, translation, mitosis, meiosis, nuclear differentiation, and/or genome rearrangement. Quantitative proteomic analyses identified 338 proteins with homologs associated with conjugation and/or somatic nuclear development in other ciliates, including dicer-like proteins, Hsp90 proteins, RNA polymerase Ⅱ and transcription elongation factors, ribosomal-associated proteins, and ubiquitin-related proteins. Four of these homologs belong to the PIWI family, each with different expression patterns identified and confirmed by RT-qPCR,which may function in small RNA-mediated genome rearrangement. Proteins involved in the nonhomologous end-joining pathway are induced early during meiosis and accumulate in the developing new somatic nucleus, where more than 80% of the germline sequences are eliminated from the somatic genome. A number of new candidate genes and proteins likely t

通过分析四川省会理烟区土壤及红花大金元烟叶各30份样品中微量元素含量,研究了会理烟区植烟土壤与烟叶中中微量元素含量之间的定量关系。结果表明:会理烟区大部分土壤中微量元素含量在较适宜的范围内,但部分土壤水溶性硼、有效锌含量较低,烟叶中铜元素、镁元素含量较缺乏;利用多元线性逐步回归分析得到土壤与烟叶中微量元素的回归方程,其中烟叶中的锰、锌含量均受到土壤中5个中微量元素的综合影响,而钙含量仅受到土壤中有效锰和交换性钙的影响;偏相关和通径分析结果表明,烟叶中微量元素与其对应的土壤内中微量元素呈极显著正相关,且直接作用系数最大。土壤中的中微量元素之间存在着广泛的协同或拮抗效应,其中土壤有效锰的含量对烟叶所有中微量元素含量的影响最大,而烟叶锌含量受土壤中其他中微量元素的影响最大。
