Determination of Phaseolin Types in Common Bean (Phaseolus vulgaris) Varieties from Turkey

Abstract

The purpose of our study was to determine the phaseolin types of common bean varieties widely consumed in Turkey through protein extraction. Twenty-four bean genotypes, consisting of 22 varieties from Kırsehir province of Turkey and two control varieties (Andean and Mesoamerican) were assessed. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) was performed with protein samples extracted from bean genotypes. Gels were stained with Coomassie blue dye R-250 and kept in fixing solution. Our analyses revealed that out of 22 bean samples, 16 contained Andean phaseolin type and 6 contained Mesoamerican phaseolin type. T-test statistical analysis was performed to determine the relationship between seed phaseolin types and seed volumes (length, height and width). The results showed that there was a significant difference between phaseolin and seed volume.

Cell Size Controls Photosynthetic Capacity in a Mesoamerican and an Andean Genotype ofPhaseolus vulgarisL

“…For instance, adaptation to a wide range of hydrological environments by species of Banksia are related to changes in morphological and anatomical characteristics that impact net assimilation (see review by Drake et al 2013; and Harrison et al 2020). Similarly, analysis of wild beans originated in central and south America indicated variabilities in photosynthetic nitrogen use efficiency, stomatal density, leaf chlorophyll content and protein solubility due to adaptation to local temperature and precipitation conditions (Gepts and Bliss, 1988; Koenig et al ., 1990; Jonathan Lynch et al ., 1992; Kami et al ., 1995; Seher et al ., 2014). Some of these modifications involved leaf size and photoperiod responses which could be associated with photosynthetic capacity (Schmutz et al ., 2014).…”
