    Abstract Appropriate knowledge of the parental cultivars is a pre-requisite for a successful breeding program. This study characterized fruit yield, quality attributes, and molecular variations of ten tomato cultivars during three consecutive generations under greenhouse conditions. Peto 86, Castle Rock, and Red Star cultivars showed the highest fruit yield (kg/plant), total phenolic compounds (TPC), and sap acidity. Principal component analysis categorized the evaluated fruit yield into three groups based on their quality attributes. A robust positive correlation appeared among traits inside each group. A positive correlation was likewise noticed between the first and the second groups. However, a negative correlation was… More >

    Phyton-International Journal of Experimental Botany, Vol.92, No.4, pp. 1275-1287, 2023, DOI:10.32604/phyton.2023.026946

    Abstract Barley (Hordeum vulgare L.) is an important economic crop for food, feed and industrial raw materials. In the present research, 112 barley landraces from the Shanghai region were genotyped using genotyping-by-sequencing (GBS), and the genetic diversity and population structure were analyzed. The results showed that 210,268 Single Nucleotide Polymorphisms (SNPs) were present in total, and the average poly-morphism information content (PIC) was 0.1642. Genetic diversity and population structure analyses suggested that these barley landraces were differentiated and could be divided into three sub-groups, with morphological traits of row-type and adherence of the hulls the main distinguishing factors between groups.

    Abstract Every breeding program that aims to create new and improved cultivars with desired traits mostly relies on information related to genetic diversity. Therefore, molecular characterization of germplasms is important to obtain target cultivars with desirable traits. Sweet potato [Ipomoea batatas (L.) Lam] is widely considered the world’s most important crop, with great diversity in morphological and phenotypic traits. The genetic diversity of 20 sweet potato germplasms originating from Bangladesh, CIP, Philippines, Taiwan, and Malaysia were compared, which was accomplished by genetic diversity analysis by exploring 20 microsatellite DNA markers for germplasm characterization and utilization. This information was effective in differentiating… More >

    XIAOJUN ZHOU*, XIAOYU LU, XUBO WANG

    BIOCELL, Vol.46, No.11, pp. 2489-2495, 2022, DOI:10.32604/biocell.2022.020311

    Abstract Euptelea pleiosperma is a characteristic species of East Asian flora with both ornamental and scientific values. Based on the reduced-representation sequencing (RRS) technology of RAD-Seq, this study conducted high-throughput Illumina paired-end sequencing to find SSR marker information in the genome of E. pleiosperma, and to screen and verify polymorphism of SSR markers. We obtained 5.5G of high-quality data using RAD-Seq. The total number of contigs of the RAD tags was 299,376, with the maximum contig length of 2,062 bp and the average length of 445 bp. From these sequences, we identified 20,718 SSR loci, with a distribution density of one… More >

    Diversity Assessment of an Endemic Carpinus oblongifolia (Betulaceae) Using Specific-Locus Amplified Fragment Sequencing and Implications for Conservation

    Sumei Li, Qing Wang, Peng Wang, Shuan Wang, Rutong Yang, Ya Li*

    Phyton-International Journal of Experimental Botany, Vol.91, No.3, pp. 617-632, 2022, DOI:10.32604/phyton.2022.017741

    Abstract Carpinus oblongifolia is an endemic species and the extant wild populations show a fragmentation distribution in the Baohua Mountain of Jiangsu Province in eastern China. Understanding of genetic diversity plays an important role in C. oblongifolia survival and sustainable development. The wild C. oblongifolia population was artificially divided into four subpopulations according to the microhabitats, and another two subpopulations were constructed by progeny seedlings cultivated with the mature seeds. Then, the leaf buds of 80 individuals from six subpopulations were sampled to develop single nucleotide polymorphisms (SNPs) using specific-locus amplified fragment sequencing (SLAF-seq). Based on these SNPs, we aimed to… More >

    Abstract Indo-Burmese region was the primary center of eggplant diversity from where the crop extended to several secondary origins of diversity. In this study, the genetic diversity among fifty-six eggplant accessions collected from three countries was assessed using sixteen polymorphic SSR markers to determine suitable parents for heterotic hybridization. The estimation of genetic diversity among the population of three countries (Bangladesh, Malaysia, and Thailand) varied from 0.57 to 0.74, with Shannon’s index value of 0.65. The mean value of expected heterozygosity and Nei’s index was 0.49, with an average PIC value of 0.83. A dendrogram was constructed based on UPGMA (unweighted… More >

    Development and characterization of Simple Sequence Repeat (SSR) markers from the genomic sequence of sweet potato [Ipomoea batatas L. (Lam)]

    HANNA AMOANIMAA-DEDE, JIACHENG ZHANG, CHUNTAO SU, HONGBO ZHU*

    BIOCELL, Vol.45, No.4, pp. 1095-1105, 2021, DOI:10.32604/biocell.2021.015053

    Abstract Sweet potato is a multifunctional root crop with many essential nutrients and bioactive compounds. Due to its genetic complexity and lack of genomic resources, efficient genetic studies and cultivar development lag far behind other major crops. Simple sequence repeats (SSRs) offer an effective molecular marker technology for molecular-based breeding and for locating important loci in crop plants, but only a few have previously been developed in sweet potato. To further explore new SSR markers and accelerate their use in sweet potato genetic studies, genome-wide characterization and development of SSR markers were performed using the recently published genome of sweet potato… More >

    MADE DIOUF1, SARA DIALLO1, FRANÇOIS ABAYE BADIANE1,2, OUMAR DIACK1, DIAGA DIOUF1,*

    BIOCELL, Vol.45, No.2, pp. 345-362, 2021, DOI: 10.32604/biocell.2021.013706

    Abstract Cowpea is one of the most important legume grains in the sub-Saharan region of Africa used for human consumption and animal feed, but its production is hampered by biotic and abiotic constraints raising the need to broaden its genetic basis. For this purpose, seeds of two cowpea varieties Melakh and Yacine were irradiated with 300 and 340 Gy of gamma-ray, respectively. The developed mutant populations were agromorphologically characterized from M5 to M7, while the genetic diversity of the latter was evaluated using 13 ISSR markers. Based on the agromorphological characterization, variation of flower color, pod length, seed coat color, and… More >

    ALI RAZA1,7,#,*, ABU BAKR UMER FAROOQ2,#, WAQAR AHMAD KHAN3, AHSAN IQBAL4, SADETTIN ÇELİK5, MAHWISH ALI6, RAO SOHAIL AHMAD KHAN1,*

    BIOCELL, Vol.44, No.4, pp. 769-776, 2020, DOI:10.32604/biocell.2020.010207

    Abstract Randomly amplified polymorphic DNA (RAPD) is a tremendously convenient approach used to discriminate between Brassica species owing to its accuracy and speed. RAPD primers generate adequate genetic information that can be used in the primer-marker system. In this work, twenty RAPD-PCR based markers were executed to generate polymorphic data, like polymorphic information content (PIC), mean resolving power (MRP), resolving power (RP), effective multiplex ratio (EMR), and marker index (MI) for the first time and genetic distance among and between six Brassica species were calculated. Our results indicated that 20 primers produced a total of 231 scored band and generated 87%… More >
