Abstract

Peanut is an allotetraploid crop with a large genome. The construction of genetic linkage map and QTL mapping of related traits has little progress for peanut. In the present study, a genetic map consisting of 20 linkage groups was constructed with 234 SSR markers based on 2653 published SSR markers by using the F₂population derived from the cross between Fuchuan Dahuasheng and ICG6375. The genetic map covers 1683.43 cM, and the length of each linkage group varies from 36.11 to 131.48 cM, the number of markers in each linkage group varies from 6 to 15, with an average distance of 7.19 cM. Combining with the data of main stem height and number of total branches of F₃ population in the environments of Wuhan and Yangluo, we performed QTL mapping and genetic effects analysis of QTLs by software WinQTLCart 2.5 using CIM (Composite Interval Mapping) method. As a result, 17 QTLs related to main stem height and number of total branches on eight linkage groups were detected with contribution percentage of 0.10%-10.22%. Comparing the QTLs detected in the environments of Wuhan and Yangluo, qMHA061.1 and qMHA062.1were in the same linkage region of markers TC1A2-AHGS0153 of linkage group LG06 with contribution percentage of 5.49%-8.95%, qMHA061.2 and qMHA062.2were between the markers AHGS1375 and PM377 on linkage group LG06 with contribution ratio of 2.93%-5.83%, qMHA092.2 and qMHA091.1 were in the same linkage region of the markers GM2839-EM87 in linkage group LG09 with contribution percentage of 0.53%-9.43%. The QTLs repeatedly detected are important for molecular breeding of peanut.

引言

分子遗传图谱广泛应用于基因定位、图位克隆以及分子标记辅助育种。栽培种花生(Arachis hypogaea L.)为异源四倍体(2n=40), 因富含脂肪、蛋白质、白藜芦醇等营养保健成分而深受人们的喜爱, 是我国第二大油料作物^{[1, 2]}。在早期的研究中, 由于栽培种花生的DNA多态性相对较为贫乏, 而野生花生的多态性丰富, 因此, 早期的花生遗传图谱的构建多以野生花生为材料^{[3, 4, 5, 6]}。随着SSR标记的大量开发, 近十多年来的研究结果显示, 栽培种花生中也存在较为丰富的遗传多态性。栽培种花生的遗传图谱的构建不断完善, 重要性状QTL的研究报道不断增多。Varshney等^[7]以栽培种花生的RIL群体为材料, 构建了1个包含135个SSR标记的连锁图, 定位了4个与抗干旱相关的QTL。Ravi等^[8]在Varshney构建遗传连锁图谱的基础上增加了56个标记, 构建了包含191个标记的图谱, 定位了13个与干旱抗性成分相关的QTL。Khedikar等^[9]利用栽培种花生的RIL群体构建了一张含有56个SSR标记涉及14个连锁群的遗传图谱, 定位到与抗锈病相关的11个分子标记。Shirasawa等^[10]构建了一张含有1114个位点的栽培种花生遗传图谱, 获得了与开花期、分枝角度、主茎高、荚果长、荚果厚和荚果宽相关的QTL共9个。Wang等^[11]利用栽培种花生的F₂群体构建了一张包含318个标记的遗传图谱, 定位到15个与番茄斑萎病毒(TSWV)相关的QTL, 37个与叶斑病相关的QTL。张新友等^[12]运用栽培种RIL群体和F₂群体定位了与产量和品质性状相关的QTL 62个。综合分析栽培种花生遗传图谱和QTL的研究结果发现, 花生遗传图谱的构建还很不完善, 缺乏高密度的遗传图谱。花生的主茎高和总分枝数是重要的农艺性状, 很多研究结果都表明, 主茎高和总分枝数与产量性状之间存在显著的相关性^{[13, 14]}, 而且主茎高还与植株的抗倒伏性相关。本文以花生的主茎高和总分枝数为调查性状, 采用2个环境下的数据, 拟构建一张遗传图谱, 这对花生的分子设计育种具有重要意义。

1 材料与方法

1.1 试验材料

根据核心种质的遗传多样性鉴定结果, 选择遗传差异较大的地方龙生型品种富川大花生为母本、从ICRISAT引进的珍珠豆型材料ICG 6375为父本配制杂交组合, 构建218个F₂单株和218个F₃家系的检测群体。

1.2 主茎高和总分枝考察

2012年将F₂材料种植于湖北武汉中国农业科学院油料作物研究所试验农场, 单株收获。2013年将上年收获的每个单株材料的种子分成两等份, 分别在武汉中国农业科学院油料作物研究所试验农场和武汉阳逻基地种植成F₃株系。单粒播种, 每行12株, 行长2.0 m, 种植密度为0.4 m× 0.2 m, 常规田间管理。收获时去掉每个株行的边株, 收获中间10株, 按《花生种质资源描述规范和数据标准》^[15]考察主茎高和总分枝数。

1.3 DNA提取及PCR扩增

选取幼嫩叶片, 采用改良CTAB法提取DNA, 用1%的琼脂糖凝胶电泳检测DNA浓度与纯度。所用引物序列来源于参考文献^{[16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33]}。PCR体系为10 μ L, 含10 mmol L^-1Tris-HCl (pH 8.3)、50 mmol L^-1KCl、300~400 μ mol L^-1 dNTPs、10~40 pmol L^-1引物对、10~20 ng模板DNA。PCR程序为Touchdown, 扩增条件为94℃预变性3 min; 93℃变性30 s, 65℃退火30 s (每个循环-1℃), 72℃延伸1 min, 共10个循环; 93℃变性30 s, 55℃退火30 s, 72℃延伸1 min, 共20个循环; 72℃延伸10 min。PCR产物经6%变性聚丙烯酰胺凝胶电泳检测, 硝酸银染色, 显影, 扫描保存。

1.4 分子标记数据统计

统计每份材料扩增的条带, 与母本相同的带型记为“ 1” , 与父本相同的带型记为“ 2” , 同时具有亲本带型的记为“ 3” , 缺失或者不清的带型记为“ 0” 。

1.5 遗传图谱构建及QTL定位

运用JoinMap 3.0构建遗传图谱, 首先采用New Project构建新的工作文件夹, 对options内的参数进行设置, 设置LOD≥ 3, 步长设置为0.05; 选择右边的LOD grouping (tree)等选项; 选择population内的create groups for mapping, 即得相应连锁群。连锁分群时应用WinQTLCart2.5复合区间作图法进行QTL定位, 以LOD值≥ 2.5作为检测标准。QTL的命名以性状加所在连锁群加年份命令, 若同一连锁群上出现2个或以上QTL时, 则QTL后面加“ .” 表示, 比如qMHA061.2表示位于LG06连锁群在第1个环境下即武汉环境下检测到的第2个与主茎高相关的QTL。

2 结果与分析

2.1 SSR多态性

利用已经公开发表的图谱上公布的SSR和EST-SSR引物^{[19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35]}共2653对在双亲(富川大花生和ICG6375)中进行筛选, 获得多态性引物275对(表1), 占8.52%。将获得的多态性引物在F₂代群体的218个单株中检测, 共检测到281个位点, 多态率为8.71%。其中AHGS1314、AHGS1470、AHGS1672、AHGS2429、TC6E1和GNB533等6对引物均扩增出了2个位点。

通过统计F₂代群体各单株的带型, 在检测到的281个位点中, 符合孟德尔分离比例的标记共137个, 占48.76%。

2.2 遗传图谱构建

根据F₂代群体中检测得到的281个多态性标记, 运用JoinMap 3.0软件进行遗传连锁分析, 获得包含20个连锁群的连锁图(图1), 各连锁群的信息列于表2。在281个多态性标记中, 有234个标记进入连锁群, 47个标记未进入连锁群。构建的图谱总长度为1683.43 cM, 连锁群长度在36.11~131.48 cM之间, 平均每个连锁群长度为84.17 cM; 每个连锁群的标记数在6~15个之间, 平均为11.7个; 相邻两两标记间的平均距离为7.19 cM, 图谱上偏分离标记共116个, 占49.57%。分析各连锁群的长度, 最长的为LG06, 达131.48 cM; 最短的为LG14, 仅36.11 cM。共有9个连锁群的长度> 84.17 cM, 包括LG01、LG09、LG10等, 其余11个连锁群的长度< 84.17 cM。比较分析各连锁群上的标记数, 发现除LG08和LG14这2个连锁群较少外(分别为6个和7个), 其余18个连锁群相对较多, 在9~15个之间。

表2结果还表明, 图谱上的相邻两两标记间的距离不同。相邻两两标记之间的距离≤ 10 cM的有162个, 占69.23%。相邻标记之间距离最小为1.61 cM, 位于LG06连锁群上的GM623与AHGS0153之间; 距离最大为 32.7 cM, 位于同一连锁群(LG06)上的AHGS1512与pPGPseq15D3之间。图谱上偏分离标记分布也不均匀。LG15连锁群上偏分离标记最多, 11个标记发生了偏分离, 占连锁群上标记数目的84.62%。LG04和LG18连锁群上的偏分离标记最少, 均只有2个标记发生了偏分离, 分别占22.22%和20%。

2.3 表型性状的变异

通过对亲本和218个F₃家系的主茎高和总分枝数在武汉和阳逻环境下的鉴定, 获得的结果列于表3。从表3看出, 2个亲本在2种环境下的差异为20 cm左右, 总分枝数相差12条左右。武汉环境下F₃的平均主茎高56.27 cm, 变异范围31.50~87.50 cm; 总分枝数17.66条, 变异范围4.00~61.00条; 主茎高和总分枝数的最高值与最低值间的差异均超出了双亲之间的差异。阳逻环境下F₃的平均主茎高54.30 cm, 变异范围31.00~86.00 cm; 总分枝数18.04条, 变异范围4.30~55.40条; 阳逻环境下的主茎高和总分枝数的最高值与最低值间的差异也均超出了双亲之间的差异。统计分析不同主茎高范围的家系数和不同分枝数范围的家系数, 获得的分布图列于图2。从图2看出, 两种环境下的主茎高分布基本一致, 符合正态分布; 总分枝数的分布也基本一致, 呈偏正态分布。

Relationship of resveratrol content and resistance to aflatoxin accumulation caused by Aspergillus flavus in peanut seeds.

Acta Agron Sin, 2012, 38: 1875-1883 (in Chinese with English abstract)

Resveratrol is an important component of phytoalexins responding to biotic and abiotic stresses. To investigate the possible influence of peanut resveratrol on aflatoxin production by Aspergillus flavus , we selected eight peanut varieties (lines) resistant or susceptible to aflatoxin accumulation resveratrol content and aflatoxin production. The results showed that the average resveratrol content (37.3 µg kg –1 ) of resistant varieties (lines) was significantly higher than that of susceptible ones (13.3 µg kg –1 ) in naturally dried seeds. Resveratrol accumulation amount increased by twice in imbibed resistant peanut seeds, and by 1.6 flod in those of the susceptible ones, and the consequent aflatoxin content declined in the imbibed seeds from 37.6% to 75.8%. However, the resistant varieties (lines) had lower aflatoxin content compared with the susceptible seeds in the imbibition treatments. Resveratrol content in peanut seeds was negatively correlated with aflatoxin production. Trials in vitro also demonstrated that resveratrol could inhibit aflatoxin production in medium. It was suggested that resveratrol is one of the phytoalexins highly related to resistance to aflatoxin production in peanut seeds. As resveratrol has been reported to have certain functions in human health protection, increased resveratrol in peanut would enhance food safety of peanut products and contribute to consumer’s health.caused by Aspergillus flavus to determine

选用抗黄曲霉产毒的花生品种 (系)和高产毒品种 ( 系), 采用强产毒菌株AF2202人工接种水分吸涨的花生种子, 培养7 d后，测定接种和未接种的花生种子中白藜芦醇及黄曲霉毒素含量，探讨白藜芦醇与花生种子黄曲霉产毒抗性之间的关系。结果表明，抗黄曲霉产毒花生品种 ( 系)的白藜芦醇含量较高，平均为37.3 µg kg –1 ，高产毒品种含量相对较低，平均为13.3 µg kg –1 ，抗、感品种之间存在显著差异。吸胀处理后抗产毒花生品种 (系)白藜芦醇含量提高2.0倍，感病品种 (系)仅提高1.6倍，对不同品种(系)处理后的种子二次接种，令黄曲霉毒素含量下降37.6%~75.8%，但吸胀处理后抗产毒品种(系)的黄曲霉毒素含量仍低于感病品种(系)。相关分析表明，花生白藜芦醇含量与黄曲霉毒素含量呈显著负相关，并且在离体培养基中添加浓度大于3.0 μg mL –1 的白藜芦醇可导致黄曲霉菌产毒量大幅下降，说明白藜芦醇对黄曲霉产毒具有抑制作用。
