“…Proline is one of the commonest osmolytes in plants, and seems to be a reliable marker of stress in Phaseolus, as in many other genera. Many reports have shown significant increases in Pro contents in Phaseolus plants submitted to water stress (23,24), but the correlation between Pro accumulation and stress tolerance remains unclear since apparently contradictory results have been reported using different bean varieties (25,26). The present study revealed that Pro accumulation is a common response to water stress in the four analysed bean cultivars, in agreement with the aforementioned published results.…”

Genetic improvement of crop drought tolerance has become an urgent need for increasing agricultural yields and food production, to feed a growing human population in the context of global climate change. To get insights into the most relevant mechanisms underlying drought resistance in beans, we have analysed the responses to water deficit of three Phaseolus vulgaris (common bean) and one P. coccineus (runner bean) cultivars, focusing on the accumulation of specific osmolytes, a conserved response to abiotic stress in plants. Changes in osmolyte levels were correlated with the relative tolerance to water stress of the studied cultivars. Drought tolerance in Phaseolus largely depends on the accumulation of myo-inositol; glycine betaine may also contribute to tolerance in P. coccineus (but not in P. vulgaris). Proline, another common osmolyte, is a reliable marker of the level of stress affecting bean plants, but is not directly involved in tolerance mechanisms, as its drought-dependent accumulation is lowest in the most tolerant cultivar. We suggest that, by measuring the levels of proline and myo-inositol in water-stressed plants, a large number of cultivars could be easily and rapidly screened to select promising candidates to be used in breeding programmes for improving drought tolerance in beans.

“…The last biomarker of stress analysed was proline (Pro), a common osmolyte in plants, which accumulates in response to different types of abiotic stress, including drought, in a large number and variety of species [25,74]. Many studies reported significant increases in Pro contents in Phaseolus plants subjected to water stress [27][28][29][30]56], in which this osmolyte seems to be involved in the stress response but not in the tolerance mechanism. In the case of Lima bean, Arteaga et al [63] found higher Pro concentration in the cultivars more tolerant to salt stress, concluding that it could play an important role in their stress tolerance.…”

Agrobiodiversity and adaptability to environmental changes derived from global warming are challenges for the future of agriculture. In this sense, landraces often have high levels of genetic variation, tightly connected with the changing environmental conditions of a territory. The genus Phaseolus, with five domesticated species, is one of the most important sources of proteins, carbohydrates and micronutrients in various countries. This study aimed to compare the adaptation capacity to drought, in the vegetative growth phase, of a commercial cultivar and two landraces traditionally cultivated in the Mediterranean basin of Phaseolus lunatus (Lima bean). Growth and biochemical responses of the analysed genotypes to different water-deficit treatments were evaluated and compared. In addition, the effectiveness of the voltammetric method for evaluating stress levels in cultivated plants was tested. The studied parameters revealed that P. lunatus is a drought-tolerant species, showing similar results for the three cultivars. However, contrary to what was expected from the germination phase results, the commercial variety Peru showed some better responses under water stress conditions. Finally, the voltammetric method proved to be a good and fast tool for assessing oxidative stress in cultivated plants, showing results in agreement with total phenolic compounds and total flavonoid fluctuations.

“…In the present study, 18 genotypes, part of the available collection of the ethyl methane sulphonate (EMS) mutant lines from the Agricultural University-Plovdiv of Phaseolus vulgaris seed collection (Svetleva et al, 2012), and local Phaseolus spp. accessions from Bulgaria were selected based on morphological field observations and preliminary physiological and molecular data (Table 1).…”

The conservation and research of genetic resources of key crops and their use in the global farming system present the main trends for developing sustainable agriculture and producing healthy food products. This study aims to investigate the available genetic resources of (Phaseolus spp. L.) landraces and breeding lines/varieties to identify promising genotypes with a view to their further use for breeding as a source of new germplasm. Investigation and evaluation of 18 accessions of Phaseolus spp. L. from Bulgaria for economically important agronomic traits and molecular approaches using ISSR and SCAR marker systems were carried out. The genetic characterization by seven SCAR markers was applied to the selected genotypes to determine the genes associated with the resistance to economically important diseases.The population structure of Phaseolus spp. L. was determined using the grouping method based on Bayesian models based on six ISSR markers and STRUCTURE software. Based on a comparison between the ISSR molecular marker and descriptors results and the higher Q value, the no admixture ancestry model and correlated allele frequencies were the parameters combination selected for describing the population structure of the selected genotypes. The correspondence between the ISSR-based analysis and the descriptors showed that 14 (77.78%) of the 18 Phaseolus accessions groups were in the same cluster in both methods. Promising genotypes have been identified based on the applied integrated research approach -phenotypic and genotypic with the potential for integrating into breeding programs as a source of new germplasm of Phaseolus spp. L.
