The dwarfing gene D-53 Is one of a few dominant genes for dwarfing In rice （Oryza satlva L.）. In the present study, our genetic analysis confirmed that mutant characteristics including dwarfing, profuse tlllerlng, thin stems and small panicles are all controlled by the dominant D-53 gene. We measured the length of each Internode of KL908, a D-53-carrylng line, and classified the dwarfism of KL908 Into the dn-type. In addition, we measured elongation of the second sheath and a-amylase activity In the endosperm, and we characterized KL908 as a dwarf mutant that was neither glbberelllc acid-deficient nor glbberelllc acid-Insensitive. Using a large F2 population obtained by crossing KL908 with a wild-type variety, NJ6, the D-53 gene was mapped to the terminal region of the short arm of chromosome 11, with one simple sequence repeat marker, Ds3, co-segregating, and the other, K81114, located 0.6 cM away.

Cotton stem trichome and seed fibers belong to the single-cell structure formed by the protrusion of epidermal cells. Compared with fibers, the cotton stem trichome are easier to observe and study, but its genetic basis and molecular mechanism are still poorly understood. After long term of observation, we found that both cultivated tetraploid cottons(Gossypium hirsutum and ***) differed greatly in stem trichome phenotype. Most *** have little or no trichome, whereas all of the cultivated G. hirsutum varieties have trichome on stem. In addition, two species have significantly difference in trichome density, length and trichome number, according to which, stem trichome of cultivated tetraploid cottons can be roughly divided into four types(Ⅰ-Ⅳ). Upland cottons normally have the long single and cluster stem trichome(type Ⅰ and Ⅱ), while Sea island cottons only have short cluster trichome(type Ⅲ and Ⅳ). genetic mapping using the F2 populations between varieties with different type of trichome and without stem trichome revealed that the type Ⅰ trichome of upland cotton were mainly controlled by genes on chromosomes A06 and D08, the type Ⅱ were mainly controlled by genes on A06, whereas the type Ⅲ and Ⅳ stem trichome of Sea Island cotton were mainly controlled by genes on D08. When more cross combinations were observed, it was found that the resultant F1 consistently showed the obvious different trihome phenotype among crosses with different type of tichome, while those from varieties with the same type of trichome showed the same trichome phenotype, suggesting that different types of trichome in tetraploid cotton were controlled by different genetic foundation. More ratio of wild upland cotton do not have trichome on their stem than modern varieties, whereas in Sea island cotton less ratio of wild accessions having the glabrous stem than modern varieties. In both Upland and Island cottons, a very close relationship between fuzzy fiber number/fiber leng

Plant height is an important agronomic trait in cereal crops. A dwarfing mutant NM9 is identified from a mutant library of the common wheat cultivar NAU9918 created by ethylmethyl sulfide（EMS） treatment of dry seeds. To identify this mutant, the phynotype, anatomical structure and endogenous hormones concentration of NM9 have been detected. The mutant plant showed obvious phenotypic differences in comparison with the wild type, especially the reduced height, increased tiller number, elongated spike and grain length. The mutant is insensitive to exogenous GA, IAA or BR. Differences of endogenous hormone concentration of ABA, IAA, GA, BR and ZR between NM9 and NAU9918 are confirmed in root, leaf and spike at different growth stages. The plant height of NM9 is dwarfed by reducing parenchyma cells elongation in internode. Allelism tests of the dwarfing gene in NM9 and varieties with different known dwarfing genes, indicating that the dwarfing gene in NM9 is non-allelic to Rht-B1 b, Rht-D1 b, Rht-B1 c, Rht-8 or Rht-D1 c. A genetic analysis using two F2 segregating populations indicated that a single recessive mutation on wheat chromosome 2 A, between two SSR markers gwm122 and gwm71. For the dwarfism phenotype and location, the dwarfing gene in NM9 is designed as Rht-x, temproarily.

Using an F2population derived from the hybrid of Lycopersicon esculentum Mill. ‘XF 98-7’× Lycopersicon pimpinellifolium LA2184, a SSR genetic linkage map of tomato is constructed. The map contains 112 markers and spans 808.4 cM with an average distance of 7.22 cM between loci. Two quantitative trait loci （QTLs） for first flower node on chromosomes 5 and 11, two QTLs for number of flowers per truss on chromosomes 2 and 5, and five QTLs for fruit weight on chromosomes 1, 2, 3, 9 and 12 are identified.

A cucumber (Cucumis sativus L.) molecular linkage map, including 79 random-amplified polymorphic DNAs (RAPD) and two genes , lb for lateral branch and f for female sex expression, is constructed from a cross between a line, S52, with weak lateral growing ability and staminate from Dabieshan Mountains area in China and another line, S06, with strong lateral growing ability and gynoecious from Europe. The map contains nine linkage groups and spans 1110.0 cM with an average distance of 13.7 cM between loci. The lb locus is located in a longer linkage group LG-2 and flanked by two markers, OP-Q5-1 and OP-M-2-2, at 9.3 cM and 15.9 cM, respectively. In the meantime, the RAPD loci, OP-Q5-2 and BC151, in a short linkage group were found to flank f at 13.7 cM and 13.4 cM, respectively. The construction of RAPD map has paved a way for further study of the genes for lateral branch, female sex expression and other agronomic traits in cucumber.

Powdery mildew, caused by Blumeria graminis f. sp. tritici （Bgt）, is one of the most damaging diseases to wheat in the world. The cultivation of resistant varieties of wheat is essential for controlling the powdery mildew epidemic. Wheat landraces are important resources of resistance to many diseases. mapping powdery mildew resistance genes from wheat landraces will promote the development of new varieties with disease resistance. The Chinese wheat landrace Baiyouyantiao possesses characteristic of disease resistance to powdery mildew. To identify the resistance gene in this landrace, Baiyouyantiao was crossed with the susceptible cultivar Jingshuang 16 and seedlings of parents and F1, BC1, F2, and F~：3 were tested with Bgt isolate E09. The genetic results showed that the resistance of Baiyouyantiao to E09 was controlled by a single recessive gene, tentatively designated PmBYYT. An Illumina wheat 90K single-nucleotide polymorphism （SNP） array was applied to screen polymorphisms between F2-resistant and F2-susceptible DNA bulks for identifying the chromosomal location of PmBYYT. A high percentage of polymorphic SNPs between the resistant and susceptible DNA bulks was found on chro- mosome 7B, indicating that PmBYYT may be located on this chromosome. A genetic linkage map of PmBYYTconsisting of two simple sequence repeat markers and eight SNP markers was developed. The two flanking markers were SNP markers W7BL-8 and W7BL-15, with genetic distances of 3 and 2.9 cM, respectively. The results of this study demonstrated the rapid characterization of a wheat disease resistance gene and SNP marker development using the 90K SNP assay. The flanking markers of gene PmBYYTwill benefit marker-assisted selection （MAS） and map-based cloning in breeding wheat cultivars with powdery mildew resistance.

Puccinia striiformis Westend. f. sp. tritici(Pst) pathotype CYR34 is widely virulent and prevalent in ***, we report identification of a strpie rust resistance(Yr) gene, designated Yr041133, in winter wheat line 041133. This line produced a hypersensitive reaction to CYR34 and conferred resistance to 13 other pathotypes. Resistance to CYR34 in line 041133 was controlled by a single dominant gene. Bulked segregant RNA sequencing(BSR-Seq) was performed on a pair of RNA bulks generated by pooling resistant and susceptible recombinant inbred lines. Yr041133 was mapped to a 1.7 c M genetic interval on the chromosome arm 7 BL that corresponded to a 0.8 Mb physical interval(608.9–609.7 Mb) in the Chinese Spring reference genome. Based on its unique physical location Yr041133 differred from the other Yr genes on this chromosome arm.
