    Functional Analysis of the Genotypic Differences in Response of Pea (Pisum sativum L.) to Calcareous-Induced Iron Deficiency

    Sameh Barhoumi1, Hasna Ellouzi2, Abdelmajid Krouma1,3,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.2, pp. 521-536, 2023, DOI:10.32604/phyton.2022.023555

    Abstract Lime-induced iron chlorosis is a major nutritional disorder causing severe plant growth and yield reduction in the calcareous soils of Tunisia. The understanding the behavior of key metabolic functions of peas on calcareous soils, the identification of useful traits of tolerance, and the exploration of the genotypic differences in response to this constraint remain the most efficient approaches due to their coast, environmental benefits, and sustainability. For this purpose, a greenhouse experiment was conducted on three pea genotypes (Alexandra: Alex, Douce de provence: DP, and Merveille de Kelvedon: MK) cultivated on calcareous soil (Fe-deficient) and fertile soil (control). Plant growth,… More >

    Physiological Responses of Pea Plants to Salinity and Gibberellic Acid

    Houneida Attia1,2,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.1, pp. 149-164, 2023, DOI:10.32604/phyton.2022.022363

    Abstract Pea is a seed legume. It is rich in cellulose fibre and protein. It is also a significant source of minerals and vitamins. In this paper, we set out to better characterize the physiological responses of Pisum sativum L. to the combined effects of NaCl, 100 mM and gibberellins (GA3). Our analysis revealed that NaCl caused a decrease in growth resulting in a reduction in root elongation, distribution and density, leaf number and leaf area, and a decrease in dry matter of roots and shoots. However, the contribution of GA3 in the salty environment induced an increase in these different… More >

    Land equivalent ratio, grain and pod yield and ethereal extract of Helianthus annuus L. in monoculture and associated with Pisum sativum L. in function of stabilized urea

    Piña-González JL1, EJ Morales-Rosales2, A Domíngez-López2, JF Ramírez-Dávila2, G Estrada-Campuzano2, O Franco-Mora2

    Phyton-International Journal of Experimental Botany, Vol.83, pp. 101-108, 2014, DOI:10.32604/phyton.2014.83.101

    Abstract The aim of this study was to assess the land equivalent ratio, biomass, grain yield and ethereal extract of Helianthus annuus in monoculture and associated with Pisum sativum in function of stabilized urea (0, 40, 80 kg N/ha) in El Cerrillo, México. It was also estimated pod yield obtained by P. sativum as a pure stand and associated with H. annuus. The six treatments (in each experiment) were evaluated in a 2 × 3 factorial experiment in a randomized complete block design with four replications. When F values were significant, the honestly significant difference test at the 5% level of… More >

    Cloning and characterization of 66 kDa streptavidin-binding peptides (SBP) of Pisum sativum L. embryo specific to var. Alaska

    BIOCELL, Vol.43, No.3, pp. 155-166, 2019, DOI:10.32604/biocell.2019.06814

    Abstract The aim of the current research was to clone and to characterize the partial 66 kDa streptavidin-binding peptide (SBP) found in the germinated embryos of Pisum sativum L. var. Alaska. The pea (P. sativum var. Alaska) embryos possess prominent 66 kDa SBPs that gradually disappeared after few hours of germination in germinated embryos, but not in the cotyledons. The total RNA was isolated from embryos of P. sativum but could not be isolated from the cotyledons. The partial nucleotides sequences of 66 kDa SBPs of embryonic stalk (P. sativum var. Alaska) were cloned and identified using pMOSBlue vector. 66 kDa… More >
