摘要
植物组织培养和遗传转化是转基因育种技术发展和应用的重要基础,而植物离体培养能力的高低是决定转基因效率的关键。已有诸多证据表明,基因型是决定植物组织培养能力的主要因素。水稻是人类的主要粮食作物之一,对水稻组织培养能力遗传机制的研究具有举足轻重的意义。
     93-11和日本晴分别是籼、粳稻的代表性品种,也是转基因难易程度高低的两个典型范例。本研究对93-11以及源自于日本晴×93-11的重组自交系群体(RIL)进行了成熟胚组织培养能力的详细评估,结合基于SNP的群体深度测序的基因型数据对组培再生相关性状进行了QTL定位,并对部分主效QTL区段注释基因进行了表达水平分析,缩小了候选基因的筛选范围。同时对亲本日本晴和93-11各生长时期的愈伤展开了抗氧化能力方面的生理生化分析。结果如下:
     1.通过不同愈伤诱导培养基(MS和NBm诱导培养基)和植株再生培养基(MSB、MSW、NBm和DL3)对93-11成熟种子胚进行组织培养能力的考察,发现:(1)NBm诱导培养基更适于对93-11愈伤的诱导;(2)以每粒愈伤平均出苗数(NRS)考察分化能力时,17天的93-11愈伤再生能力最强,之后随继代培养时间的延长逐渐下降,其中DL3再生培养基对于培养40天以内的93-11愈伤具有最好的植株再生表型,但对于50天的愈伤已无优势;而以植株再生率(RR)考察时,不同培养基对不同培养时间的93-11愈伤的再生能力影响不大。
     2.将愈伤诱导、分化和植株再生过程分解为十个性状(ICC、ICS、ICF、ICR、 CIR、CPA、CBA、CGA、NRS和RR)对RIL进行组培能力考察,结果表明:(1)本实验的表型鉴定过程具有良好的可重复性,且各性状评价指标之间大都存在显著或极显著的相关性;(2)群体各株系组培能力表现各异,大部分性状各株系表型差异呈现连续分布状态,且均出现超亲分离现象,其中CBA、CGA、 NRS、RR呈现出严重偏态分布,预示着控制相关性状的主效基因的存在。
     3.结合SNP为基础的bin图谱和RIL的九个表型进行QTL定位,共找到25个QTL,分布在除1,4,8,11以外的其它8条染色体上,LOD值介于3.12和9.09之间,表型贡献率从5.99%至21.91%,两个亲本对部分表型都有不同程度的贡献,以第7号染色体上QTL区域效应值最高。此外,还发现了8组QTL共定位现象。
     4.通过对与性状CGA、NRS和RR相关定位存Chr.7上的主效QTL共定位区域(95%置信区间)内的注释基因进行RNA表达水平分析,发现27个基因在日本晴和93-11间有明显差异表达,大大缩小了候选基因的范围。
     5.对日本晴和93-11不同时期愈伤的酶活性水平进行测定,包括:总抗氧化能力(T-AOC)、过氧化物酶(POD)活性和超氧化物歧化酶(SOD)活性。结果表明,T-AOC受基因型影响,93-11愈伤分化后期T-AOC活性的大幅增加与这时期愈伤的褐化死亡有关。
The development and application of transgenic breeding technology is deeply depended on the success of plant tissue culture and genetic transformation, and the genetic transformation efficiency of plant is largely rest with it's tissue culturability. It has been evidenced in numerous cases from previous studies that the tissue culture response of plant was strongly genotype-dependent. Since rice is one of major cereal crops for human, the study on the genetic mechanism of tissue culture capability in rice has very important significance.
     93-11(Oryza sativa ssp. indica) and Nipponbare (Oryza sativa ssp.japonica) are not only the representatives for the sub-species of indica and japonica, but also the typical varieties as the most difficult and the easiest host genotype for gene transformation in rice, respectively. In this study, the tissue culture response of93-11on different culture medium was firstly investigated. In order to clarify the genetic mechanisms of tissue culture, the quantitative trait loci (QTLs) associated with in vitro tissue culture response from mature seed were then identified by using a high quality genetic map based on the SNPs generated from deep sequencing of140recombinant inbred lines (RILs) derived from Nipponbare×93-11. The expression patterns of candidate genes existes in the genomic region of the major QTL with great effect were analyzed and physiological and biochemical characteristics mainly about the level of reactive oxygen species of two parent calli in various phases were also conducted. The results are summarized as follows:
     1. Two callus-induced media (MS and NBm) and four plant-regenerated media (MSB, MSW, NBm and DL3) were tested to survey the tissue culture capability of93-11mature seed, and it was found that:(1) NBm callus-induced medium is more suitable for callus induction of93-11mature seed than MS callus-induced medium;(2) When the parameter of the mean number of regenerated shoots (NRS) was used for investigating the differentiation ability of callus, DL3plant-regenerated medium is the best one among four media for93-11callus cultured less than40days; however, no obvious discrepancy was found when the parameter of regeneration rate (RR) was employed to valuate the callus differentiation ability no matter which kind of medium was used and how long the subculture was taken place.
     2. The process of callus growth (induction and differentiation) for the whole RIL was dissected into and investigated from ten indices, including ICC (induced-callus colour), ICS (induced-callus size), ICF (induced-callus friability), ICR (induced-callus rigidity), CIR (callus induction rate), CPA (callus proliferation ability), CBA (callus browning ability), CGA (callus greening ability), NRS and RR, respectively. The results indicated:(1) Reproducibility of phenotypic evaluations has satisfactorily achieved in this study, which is evidenced by the high correlations between the data generated from the replicates, and also the different indices.(2) Various phenotypes of the rice RIL were observed, and the population difference for most of indices presented continuous distribution. Moreover, transgressive segregation was found for all indices and even severe skew distributions were discovered in four indices (CBA, CGA, NRS and RR).
     3. A total of25QTLs,2each for ICC, ICS, ICF, CIR and CBA,3for CPA,4each for CGA, NRS and RR, respectively, were detected and located on eight rice chromosomes except chromosome1,4,8and11. The LOD value of all QTLs ranged from3.12(gNRS-12) to9.09(qCGA-7), and phenotypic effect (R2) variances explained by the individual QTL were in a rang between5.99%(qCPA-10) and21.91%(qCGA-7). Eight groups of QTL co-location were identified for eight indices and the additive effects came from both Nipponbare and93-11, respectively.
     4. In order to reduce the number of candidate genes responsible for major QTL associated with CGA, NRS and RR, the candidate genes were screened in the genomic region located on Chromosome7with95%confidence, and27candidate genes were found with differential expression.
     5. Total-antioxidative capacity (T-AOC), peroxidase (POD) activity and superoxide dismutase (SOD) activity of callus in various phases for Nipponbare and93-11were assessed to survey their situation of reactive oxygen species. The results revealed that T-AOC was clearly genotype-dependent and, the drastically increase of T-AOC in later period of differentiation for93-11callus was closely related with callus drowning and death.
