Assignment of unanchored scaffolds in genome of Brassica napus by RNA-seq analysis in a complete set of Brassica rapa-Brassica oleracea monosomic addition lines

借助全套白菜-甘蓝单体附加系的转录组数据定位甘蓝型油菜基因组中未锚定位置的测序片段

 HUO Dong-ao, ZHU Bin, TIAN Gui-fu, DU Xu-ye, GUO Juan, CAI Meng-xian

起源于两个祖先二倍体种,白菜(AA, 2n=20)和甘蓝(CC, 2n=18)种间杂交的经济油料作物甘蓝型油菜具有非常复杂的基因组结构。其超过10%的测序组装序列未能锚定到对应染色体上,这些序列大部分归属于C亚基因组。先前,利用已获得的重组型祖先白菜,在异源四倍体甘蓝型油菜品系“Oro”的遗传背景中,一整套的甘蓝型油菜A亚基因组附加一条C亚基因组染色体的单体附加系被获得。这套单体附加系有效降低了甘蓝型油菜基因组的复杂性。于此,我们评估了那些属于未锚定序列基因在单体附加系和重组型白菜中的表达植。随后通过对这些基因表达量的多重比较确定未能锚定的测序序列属于哪一条C基因组染色体。一共54.68%(44.11Mb)的未锚定的C基因组序列(80.67Mb)分配到对应的C基因组染色体上。这项工作显示出该套附加系在提升甘蓝型油菜基因组质量方面的价值

Strategies to enhance cottonseed oil contents and reshape fatty acid profile employing different breeding and genetic engineering approaches

 Iram Sharif, Jehanzeb Farooq, Shahid Munir Chohan, Sadaf Saleem, Riaz Ahmad Kainth, Abid Mahmood, Ghulam Sarwar

Cottonseed oil is the valuable byproduct extracted after seed cotton processing for lint. It confers a huge contribution to total vegetable oil production and ranked the 2nd to meet global edible oil requirements. Over centuries, breeders mainly focused to improve lint production and fiber quality. Now attention has been given to improve the cottonseed oil percentage, its functional and nutritional properties. However, these efforts are less than other major oilseed crops which left cottonseed oil market behind in term of consumer demand and kept cottonseed oil industry at vulnerable position. Considerable progress has been made to alter the relative percentage of fatty acid composition still intensified efforts have been required to meet the global oilseed demand. The objective of this review is to explore the cotton germplasm variation for seed oil carrying potential, its utilization in suitable breeding programs, seed oil biosynthetic pathways, major genes, and QTLs linked to quantity and quality enhancement of oil and deployment of modern genomic tools, viz., gene silencing and transgenic development to ameliorate its nutritional properties.

Assessment of genetic effects on important breeding traits in reciprocal DH populations of winter oilseed rape (Brassica napus L.)

 Laurencja Szała, Teresa Cegielska-Taras, Elżbieta Adamska, Zygmunt Kaczmarek

Here we present a study on the genetic effects of agronomic and seed quality traits in double haploid (DH) populations, which were developed by microspore culture from reciprocal F1 hybrids produced between cultivar Californium and DH W-15. Each of the populations consisted of 25 DH lines. The field experiments were conducted in a randomized complete block design with three replications during three growing seasons. Field observations were recorded on seed yield and its structure: the number of branches and pods per plant, the number of seeds per pod, the 1 000-seed weight, the content of fat in the seeds, and three unsaturated fatty acids (oleic, linoleic, linolenic) in the seed oil. In order to investigate the influence of cross direction on the studied traits, parental effects were evaluated on the basis of differences between reciprocal DH populations. The maternal effect was revealed on the number of seeds per pod and the effect of the paternal form on linolenic acid content. The occurrence of transgression effects also depended on the direction of crossing and this was particularly noticeable in terms of the number of seeds per pod. The use of multivariate statistical methods allowed for the simultaneous characterization and grouping of tested lines in terms of several traits. Graphic images of the distribution of DH lines in the space of the two first canonical variates showed a great variation between the two reciprocal populations, both in terms of yield and its components, as well as fat and those unsaturated fatty acids.

Physiological and molecular responses to cold stress in rapeseed (Brassica napus L.)

甘蓝型油菜对低温胁迫的生理及分子应答

 YAN Lei, Tariq Shah, CHENG Yong, LÜ Yan, ZHANG Xue-kun, ZOU Xi-ling

本研究以不同耐寒性油菜品种1801和C20为材料,分析油菜在不同低温胁迫条件下(4℃,2℃,0℃,-2℃和-4℃)的响应机制。结果表明:在-2℃和-4℃低温条件下,C20和1801幼苗存活率分别为0%-0%和100%-75%。低温胁迫条件下,1801幼苗中脯氨酸、可溶性糖、可溶性蛋白的积累量和抗氧化酶酶活性的积累量均大于C20;1801幼苗脱落酸和赤霉素的含量增加,C20幼苗脱落酸含量增加,赤霉素的含量无显著变化。4℃条件下,与对照相比,C20和1801幼苗中过氧化氢和丙二醛的含量均增加,当温度下降至-2℃和-4℃时,1801幼苗中过氧化氢和丙二醛的含量持续下降。通过实时荧光定量PCR测定了1801和C20在低温胁迫下抗寒基因COLD1CBF4COR6.6COR15COR25的表达量变化,结果表明1801幼苗中抗寒基因的表达量远高于C20。低温胁迫下,与C20相比,1801在激素水平、抗氧化物酶活性及渗透调节方面具有更强的调控作用。本研究为油菜低温胁迫的生理和分子应答机制研究提供了重要参考。

Simple model based on artificial neural network for early prediction and simulation winter rapeseed yield

 Gniewko Niedbała

The aim of the research was to create a prediction model for winter rapeseed yield. The constructed model enabled to perform simulation on 30 June, in the current year, immediately before harvesting. An artificial neural network with multilayer perceptron (MLP) topology was used to build the predictive model. The model was created on the basis of meteorological data (air temperature and atmospheric precipitation) and mineral fertilization data. The data were collected in the period 2008–2017 from 291 productive fields located in Poland, in the southern part of the Opole region. The assessment of the forecast quality created on the basis of the neural model has been verified by defining forecast errors using relative approximation error (RAE), root mean square error (RMS), mean absolute error (MAE), and mean absolute percentage error (MAPE) metrics. An important feature of the created predictive model is the ability to forecast the current agrotechnical year based on current weather and fertilizing data. The lowest value of the MAPE error was obtained for a neural network model based on the MLP network of 21:21-13-6-1:1 structure, which was 9.43%. The performed sensitivity analysis of the network examined the factors that have the greatest impact on the yield of winter rape. The highest rank 1 was obtained by an independent variable with the average air temperature from 1 January to 15 April of 2017 (designation by the T1-4_CY model).

花生

Arbuscular mycorrhizal fungi combined with exogenous calcium improves the growth of peanut (Arachis hypogaea L.) seedlings under continuous cropping

丛枝菌根真菌与钙协同促进连作花生生长发育

 CUI Li, GUO Feng, ZHANG Jia-lei, YANG Sha, MENG Jing-jing, GENG Yun, WANG Quan, LI Xinguo, WAN Shu-bo

连作严重影响花生生长和产量。丛枝菌根真菌(Arbusular mycorrhizal fungi)和钙离子(Ca2+)在提高植物逆境抗性方面已有很多报道,但对连作花生生长发育的影响还未有研究。本试验通过AMF(Glomus mosseae)结合外源Ca2+对连作花生苗期生长影响的研究。结果表明,二者共同作用显著增加连作条件下花生苗期植株生物量,提高叶片中Ca2+含量、总叶绿素含量、Fv/Fm的比值、抗氧化物酶(POD、SOD和CAT)的活性,降低MDA的含量;另外,AMF结合外源Ca2+显著提高连作花生植株苗期根系活力、根系中总酚和类黄酮含量。为了探讨AMF结合外源Ca2+是如何协同作用提高连作花生生长,进一步分析了不同处理AhCaMAhCDPKAhRAM1AhRAM2基因的表达。结果表明,这些基因在AMF和Ca2+的共同处理下表达水平要显著高于AMF或外源Ca2+单独处理的,表明外源Ca2+可能参与AMF与寄主共生体的形成过程,而共生体的形成可能涉及Ca2+信号转导途径。总之,AMF与外源Ca2+共同作用促进了连作花生的生长发育,这为解决作物连作障碍提供一种可持续的生态的实践方法

Estimates on nitrogen uptake in the subsequent wheat by above-ground and root residue and rhizodeposition of using peanut labeled with 15N isotope on the North China Plain华北平原花生15N同位素标记植株残茬和根际沉积对下季小麦氮素吸收的估算

 ZHANG Kai, ZHAO Jie, WANG Xi-quan, XU He-shui, ZANG Hua-dong, LIU Jing-na, HU Yue-gao, ZENG Zhao-hai

豆科作物在提高作物产量和提高土壤肥力方面发挥着重要作用。因此,它可以作为提高土壤肥力的有机氮源。本研究的目的是量化标记后花生和小麦植株根际沉积、根系和地上生物量中的氮含量,并估算花生残茬氮和土壤残留氮对下季小麦生长的影响。采用棉芯法15N同位素标记的花生和小麦于2014年在中国农业大学吴桥实验站种植,花生残茬设计4个处理,分别为花生残茬不还田(CR0)、花生地上残茬还田(CR1)、花生地下残茬还田(CR2)和花生整株残茬还田(CR3),处理间随机排列。结果表明,在花生和小麦的地上组织(叶子和茎)中积累的被标记15N同位素分别为31.5%和21%。被15N同位素标记的花生和小麦根际沉积氮分别占地下15N同位素的14.91%和3.61%。同位素标记的4个处理CR0、CR1、CR2和CR3地下15N同位素能为下季小麦提供的15N同位素,分别为11.3、5.9、13.5和6.1%。研究认为花生残茬通过在土壤中的分解和氮的根际沉积,对土壤中的氮含量有显著贡献。根据华北平原目前的花生生产水平,可以估算出花生残茬每年可以替代10.5万吨的氮肥。因此,在华北平原复种种植模式中引入花生作物可有效降低农田氮肥的使用并提高种植系统的可持续性

Characterization of groundnut (Arachis hypogaea L.) collection using quantitative and qualitative traits in the Mediterranean Basin

✺ Engin Yol, Seymus Furat, Hari D Upadhyaya, Bulent Uzun

This study was conducted to determine the genetic diversity and relationship among 256 groundnut genotypes of which 132 belong to subsp. hypogaea (Arachis hypogaea L.) and 124 to subsp. fastigiata (Arachis fastigiata L.). The collection was evaluated for eight quantitative and five qualitative traits during three consecutive years under Mediterranean climate conditions. The information on variations in quantitative and qualitative traits identified in the present investigation provided useful genotypes which would be serving parents. These parental genotypes can be used in groundnut breeding programs to develop desirable cultivars in Mediterranean Basin and globally.
