Fish and AgNor-mapping of the 45S and 5S rRNA genes in wild and cultivated Capsicum species (Solananceae)
(National Research Council Canada-NRC Research Press, 2016-02)
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 ...
A gene-derived SNP-based high resolution linkage map of carrot including the location of QTL conditioning root and leaf anthocyanin pigmentation
(BioMed Central, 2014-12)
Purple carrots accumulate large quantities of anthocyanins in their roots and leaves. These flavonoid pigments possess antioxidant activity and are implicated in providing health benefits. Informative, saturated linkage ...
Expression and mapping of anthocyanin biosynthesis genes in carrot
(2013-07)
Anthocyanin gene expression has been extensively studied in leaves, fruits and flowers of numerous plants. Little, however, is known about anthocyanin accumulation in roots of carrots or other species. We quantified ...
Mapping a gene on wheat chromosome 4BL involved in a complementary interaction with adult plant leaf rust resistance gene LrSV2
(Springer, 2018-11)
Key message: A complementary gene toLrSV2for specific adult plant leaf rust resistance in wheat was mapped on chromosome 4BL, tightly linked toLr12/31. Abstract: LrSV2 is a race-specific adult plant leaf rust (Puccinia ...
Fine mapping and epistatic interactions of the vernalization gene VRN-D4 in hexaploid wheat
(2014-02)
Wheat vernalization requirement is mainly controlled by the VRN1, VRN2, VRN3, and VRN4 genes. The first three have been cloned and have homoeologs in all three genomes. VRN4 has been found only in the D genome (VRN-D4) and ...
Mapping a gene on wheat chromosome 4BL involved in a complementary interaction with adult plant leaf rust resistance gene LrSV2
(Springer, 2018-08)
A complementary gene to LrSV2 for specific adult plant leaf rust resistance in wheat was mapped on chromosome 4BL, tightly linked to Lr12 / 31. LrSV2 is a race-specific adult plant leaf rust (Puccinia triticina) resistance ...
Physical mapping of the 5S and 18S-25S rRNA genes by FISH as evidence that Arachis duranensis and A. ipaensis are the wild diploid progenitors of A. hypogaea (Leguminosae)
(Botanical Society of America, 2004-09)
The 5S and the 18S-25S rRNA genes were physically mapped by fluorescent in situ hybridization (FISH) in all botanical varieties of cultivated peanut Arachis hypogaea (2n = 4x = 40), in the wild tetraploid A. monticola, and ...
Carotenoids gene markers for sweetpotato (Ipomoea batatas L. Lam): applications in genetic mapping, diversity evaluation and cross‑species transference
(Springer, 2014-04)
Carotenoids play essential biological roles in plants, and genes involved in the carotenoid biosynthesis pathway are evolutionarily conserved. Orange sweetpotato is an important source of β-carotene, a precursor of vitamin ...
Development of anthocyanin markers: gene mapping, genomic analysis and genetic diversity studies in Ipomoea species
(Academia Brasileira de Ciencias, 2022)
The anthocyanins are pigments responsible for a wide range of colours in plants, from blue, red and purple, play essential biological roles as well as their genes are evolutionarily conserved. Purple sweet potatoes have ...
Mapping and candidate gene identification of loci determining tolerance to greenbug (Schizaphis graminum, Rondani) in barley
(Springer, 2013-08)
Greenbug is one of the most aggressive pests of barley and wheat. In Argentina, yield losses of wheat, barley, oat and sorghum crops caused by greenbug are chronic and at times severe. Since Marker Assisted selection for ...
