The colour of plant organs is a useful trait in crop breeding. The pod colours of soybeans primarily include black, brown and tan types, which are controlled by two classical genetic loci, L1 and L2. Most wild soybeans have black pods, which reflect a possible role in adaptation to the natural environment. Here, an improved chromosome segment substitution line (CSSL) population SojaCSSLP3 was established to identify the L1 gene. The segment on the 19th chromosome represented by the SSR marker Satt313 was found to link with locus L1. The region was further delimited three times with increased SSR and InDel markers using a population derived from a heterozygous plant of CSSL124 from SojaCSSLP3. The L1 gene was finally located in a 184.43‐kb region between SSR_19p09 and Indel_19P7. Thirteen putative genes in this region were analysed with qRT‐PCR. The expression level of Glyma19 g27460, which is a member of the SANT superfamily with a MYB DNA‐binding domain, was significantly upregulated in black pods and was recognized to be the most likely candidate for the L1 gene.  相似文献   

Phenotypic variation within a Hungarian landrace of runner bean (Phaseolus coccineus L.)

Summary A landrace seed lot of runner bean (Phaseolus coccineus L.), obtained from the Budapest region, Hungary, was separated into five seed groups according to seed coat colour. 131 plants were grown randomly, and observed for 27 morphological and physiological characters. The collected data were analysed by ANOVA.Numerical taxonomy of the data employed Principal Components Analysis to generate scatter diagrams and Cluster Analysis to generate dendrograms, both before and after removing data on the four anthocyanin colour characters (seed coat, calyx, stem and flower colour) as these characters are probably controlled by a single major gene. The progenies from the five distinct parental seed groups showed much overlap in characteristics, indicating that they were not distinct lines but comprised a largely panmictic population.Some character associations were detected: plants from white seeds matured significantly later than those from black seeds, plants from white seeds with a few dark spots produced seeds significantly heavier than average, whereas those from white or black seeds produced significantly lighter seeds, although the average seed yield per plant did not differ significatly.  相似文献   

Discovery of a new gene causing dark green cotyledons and pathway of pigment synthesis in lentil (Lens culinaris Medik)     

B. Sharma  M.K. Emami 《Euphytica》2002,124(3):349-353

A new gene is reported which functions as a master gene for synthesis of the pigments determining cotyledon colour in lentil. This gene is different from the two earlier reported genes which are responsible for synthesis of yellow (gene Y) and brown (gene B) pigments. Double recessive homozygous condition of these two genes results into loss of both pigments and, consequently, produces light green cotyledons. The new gene, in contrast, produces dark green cotyledons in recessive condition irrespective of the dominance or recessive state of the Y and B genes. It is hypothesized that the new gene for dark green cotyledon colour (Dg) acts at an earlier stage in the biosynthesis of the two cotyledon-specific pigments, which are derived from a common precursor, whose synthesis is blocked when Dg mutates to its recessive condition. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献   

Inheritance of seedling colour in faba bean (Vicia faba L.)     

P. L. J. Metz  A. van Norel  A. A. M. Buiel  J. P. F. G. Helsper 《Euphytica》1992,59(2-3):231-234

Summary The inheritance of purple seedling colour was studied, in relation to the genetic control of flower colour. It was found that purple seedling colour is likely to be controlled by a single gene and that the trait is dominant over green seedling colour. White flowering prohibited the expression of the purple seedling colour, and is therefore thought to be epistatic.This character can be used to estimate rate of outcrossing in breeding programmes, as well as contribute to our knowledge of the biosynthesis of plant pigments and secondary metabolites such as tannins.  相似文献   

Introgression of alleles of the isozymic locus glucosephosphate isomerase-2 (GPI-2) from the CC genome of Brassica carinata to the CC genome of Brassica alboglabra and their independent segregation from seed colour     

M. H. Rahman   《Plant Breeding》2001,120(4):363-364

A yellowish brown‐seeded Brassica alboglabra was resynthesized from a (B. alboglabra×Brassica carinata) ×B. alboglabra cross, followed by self‐pollination. The resynthesized B. alboglabra lost the allele of the isozymic locus glucosephosphate isomerase‐2 (GPI‐2) from natural B. alboglabra, which was replaced by an allele from the corresponding genome in B. carinata. A simple Mendelian segregation of these two alleles was observed in the F₂ population of a natural × resynthesized B. alboglabra cross. Furthermore, these two alleles segregated independently from the seed colour.  相似文献
