“…In what is now Mexico, common bean was likely domesticated concurrently with maize as part of the 'milpa' cropping system (featuring common bean along with maize and squash), which was adopted throughout the Americas 10 . Domestication led to morphological changes, including increased seed and leaf sizes, changes in growth habit and photoperiod responses 11 , and variation in seed coat color and pattern that distinguish culturally adapted classes of beans 12 .…”

Common bean (Phaseolus vulgaris L.) is the most important grain legume for human consumption and has a role in sustainable agriculture owing to its ability to fix atmospheric nitrogen. We assembled 473 Mb of the 587-Mb genome and genetically anchored 98% of this sequence in 11 chromosome-scale pseudomolecules. We compared the genome for the common bean against the soybean genome to find changes in soybean resulting from polyploidy. Using resequencing of 60 wild individuals and 100 landraces from the genetically differentiated Mesoamerican and Andean gene pools, we confirmed 2 independent domestications from genetic pools that diverged before human colonization. Less than 10% of the 74 Mb of sequence putatively involved in domestication was shared by the two domestication events. We identified a set of genes linked with increased leaf and seed size and combined these results with quantitative trait locus data from Mesoamerican cultivars. Genes affected by domestication may be useful for genomics-enabled crop improvement.

“…Generally, the variation in colors is controlled by many loci involved in the biosynthetic pathway of pigments, including flavonoid, anthocyanin and melanin (Clegg and Durbin, 2000;Klungland and Vage, 2000;McClean et al, 2002). The underlying genetics of pigmentation is so complex that understanding the genetic factors causing phenotypic variation is still incomplete, although molecular studies are now advancing for some species.…”

“…The variations in flower colors (Clegg and Durbin, 2000), coat patterns and colors of seeds (McClean et al, 2002) and coat colors of animals (Klungland and Vage, 2000) are typical examples for unordered categorical traits. Moreover, scores obtained by the sensory test for eating qualities of fruits or meats, which are composite traits affected by many constituent biochemical attributes, cannot be described by a simple quantitative genetic model, thus, should be regarded as unordered categorical traits, although the scores may be ordered according to the evaluation of flavors, textures and so on, and have been analyzed with a method based on the conventional linear model (King et al, 2000;Causse et al, 2001Causse et al, , 2002.…”

Many traits including shapes and colors of flowers, fruits and seeds in plants, as well as coat colors and some behavioral properties in animals, are recorded in discrete categories. If categories are ordered, genetic analyses of the categorical traits are often performed using the threshold model, which considers a latent continuous variable, called the liability, underlying a trait and assumes the monotonic relationship between the phenotype and the liability. In some categorical traits, however, descriptions of phenotypes are purely nominal and the phenotypic scores cannot be ordered. The threshold model is unreasonable for the analyses of such unordered categorical traits. In this study, we developed a method for interval mapping of loci affecting unordered categorical traits with more than two categories. The probability of the phenotype of an individual falling in each of the categories was expressed by a polychotomous logistic model, in which the log-odds for each category relative to the reference category were assumed to follow a linear model including genotype at a locus affecting a trait as covariate. Based on the model, the interval mapping using a maximum likelihood method was devised for the analysis of complex categorical traits described with unordered categories. We confined ourselves to the case of F2 populations derived from a cross between two inbred lines, although this approach can easily be extended to the analyses for other populations of general structures. As results of analyses of simulated data show, the method showed high efficiency in detecting the loci affecting unordered categorical traits.

S u m m a r y Introduction:The common bean (Phaseolus vulgaris L.) is an annual plant grown in many countries all over the world including its different varieties in Poland. Herbal raw material are elongated pods -pericarp. Phaseoli pericarpium decreases the glucose blood level. Phaseoli pericarpium extracts manifest duretic properties, can be used in the treatment of edema, kidney diseases with decreased urinary excretion, nephrolithiasis. Objectives: To investigate the usefullness of selected excipients as carriers of dry extract from Phaseolus vulgaris pericarp. Methods: The method of direct tableting was used. In the further stage, the obtained tablets were subjected to appropriate tests. The first stage of the study evaluates Prosolv SMCC 50, PROSOLV EASYtab, EMDEX, Carmellose calcium and PRUV. These were used to manufacture 4 batches of tablets. In the second stage, an oral solid dosage was manufactured on the basis of the formulation composition of batch 1 tablets (Phaseoli pericarpium extract, Prosolv SMCC 50, PRUV). Then, different surfactants (cholesterol oxyethylate n TE = 30, cholesterol oxyethylate n TE = 40, Rofam n TE = 50), were successively added to this formulation, to obtain 3 batches of tablets. All 7 batches were manufactured in the Erweka tableting machine. Then, they were subjected to morphological tests and physicochemical evaluation. The release of active substances to 3 selected acceptor fluids (water, artificial gastric juice, artificial intestinal juice) was measured in accordance with the requirements of the general and specific monographs in European Pharmacopoeia 7. Results: The manufactured tablets had a smooth uniform surface with no stains, spalls or mechanical damage and yellow color originating from the extract. The obtained tablets, with surfactants in their com- INTRODUCTIONPhaseolus is a genus of the family Fabaceae including about 200 species of annual and perennial plants, vines and subshrubs with large leaves and white, yellow or red flowers [1]. The common bean (Phaseolus vulgaris L.) belongs to this family. It is an annual plant originating from South America. It is cultivated in many countries, including Poland, for food, dry seeds and immature pods. It exhibits a wide variety of seed coat patterns and colors [2,3].The pharmacopoeic material described in the Polish Pharmacopoeia VI [4] is the dried pericarp (bean pod, Phaseoli pericarpium) derived only from white-flowered cultivars of Phaseolus vulgaris. The pericarps are curled and slightly thin, up to 20 cm long and up to 2 cm wide. One end has a short beak-like point, while a 1 cm stalk is often attached to the other. The outside surface is pale yellow or dark brown yellow, the inside is covered with a whitish, shiny membrane. In the areas where seeds are present, the pericarp is concave inside and convex outside [4].The main pharmacologically active compounds of Phaseoli pericarpium are: choline, amino acids (arginine, asparagine, leucine, lysine), pipecolic acid, trigonelline, allantoin, phenolic acids, mineral ...
