Ling Qiu et al.
PCR-based rye (Secale cereale L.) chromosome-specific markers can contribute to the effective utilization of elite genes of rye in wheat (Triticum aestivum L.) breeding programs. In the present study, 578 new PCR-based rye-specific markers ...
FISH and AgNor mapping of the 45S and 5S rRNA genes in wild and cultivated species of Capsicum (Solananceae) [0.03%]
野生和栽培辣椒物种(茄族)中45S和5S rRNA基因的鱼和AgNor染色体定位

Marisel A Scaldaferro et al.
Chromosome number and position of rDNA were studied in 12 wild and cultivated species of the genus Capsicum with chromosome numbers x = 12 and x = 13 (22 samples). For the first time in these species, the 5S and 45S rRNA loci were localized...
Development of a high-resolution melting marker for selecting Fusarium crown and root rot resistance in tomato [0.03%]
开发用于筛选番茄抗链格孢菌冠腐和根腐病的高分辨率熔解标记
Bichseam Kim,Nahui Kim,Jun Young Kim et al.
Bichseam Kim et al.
Fusarium crown and root rot is a severe fungal disease of tomato caused by Fusarium oxysporum f. sp. radicis-lycopersici (FORL). In this study, the genomic location of the FORL-resistance locus was determined using a set of molecular marker...
Extensive length variation in the ribosomal DNA intergenic spacer of yellow perch (Perca flavescens) [0.03%]
条斑鲈(Perca flavescens)核糖体DNA间隔区的高度多态性变异

Bidénam Kakou
The intergenic spacer (IGS) is located between ribosomal RNA (rRNA) gene copies. Within the IGS, regulatory elements for rRNA gene transcription are found, as well as a varying number of other repetitive elements that are at the root of IGS...
Insight into octoploid strawberry (Fragaria) subgenome composition revealed by GISH analysis of pentaploid hybrids [0.03%]
五倍体杂交草莓(GISH分析)揭示八倍体草莓(Fragaria)亚基因组组成的新见解
Bo Liu,Elizabeth G Poulsen,Thomas M Davis
Bo Liu
As the product of interspecific hybridization between its two ancestral octoploid (2n = 8x = 56) species (Fragaria chiloensis and F. virginiana), the cultivated strawberry (F. ×ananassa) is among the most genomically complex of crop plants...
Chromosomal mapping of H3 histone and 5S rRNA genes in eight species of Astyanax (Pisces, Characiformes) with different diploid numbers: syntenic conservation of repetitive genes [0.03%]
八种不同二倍体数的Astyanax鱼类中H3组蛋白和5S rRNA基因的染色体定位：重复序列基因的同线性保留
