Summary

Crops are used to diversify the human diet, improve health, and enhance the living environment. Crops have a complex genetic basis that makes it difficult to develop improved agronomic, physiological, and nutritional quality traits. Multiple abiotic and biotic stressors (such as salts, droughts, climate change, heavy metals, disease attacks, minerals, nutrients, etc.) severely impair crop yield, quality, and other associated traits. In recent years, numerous biotechnological (genetics and breeding approaches) and biological strategies (not limited to those based on emerging OMICS technologies) have significantly assisted in increasing sustainable crop production, with improved yields, quality, and better environmental adaptability. However, studies on the genetic diversity of crops are not comprehensive enough, and the genetic basis of crop-specific traits has not been systematically analysed. Thus, it is necessary to explore the potential variation of related traits based on unique genetics, genomics, phenomics, and physiology-based research that would offer vital insights for an in-depth understanding of advanced, significant regulatory mechanisms in crop plants, aiming at the development of improved varieties. Thus, it is imperative to explore the new genetic variations of related traits at the physiological and molecular levels to discover and utilize the key novel genetic resources.

 

The multi-direction studies (not restricted to particulars) on the genetics, genomics, breeding, pathology, and physiology aspects of large agricultural plant species are the focus of this special issue. We warmly invite manuscripts that emphasise useful biological applications and cutting-edge biotechnological techniques for enhancing crop productivity under broad scenarios.

 

Scope of the Special Issue:

• Emerging research on genetics, genomics, and physiology of crop plants.

• Application of improved biological methods for crop cultivation.

    Abstract Bell pepper (Capsicum annuum L.), along with potato and tomato, is one of the three most cultivated vegetables in the world. Bell pepper is worldwide accepted due to its characteristics of color, smell, flavor, and texture. Bell pepper is also considered a nutritious food due to its vitamin and antioxidant contents. In Mexico, bell pepper production has a high value because it is grown for the international markets, particularly the United States of America. Nevertheless, the abscission of flowers and fruits is a factor that limits the yield, hinders the planning of activities, and causes a More >

    Genetic Variability and Phenotypic Correlations Study among Grain Quality Traits and Mineral Elements Concentrations in Colored and Non-Colored Rice (Oryza sativa L.)

    Phyton-International Journal of Experimental Botany, Vol.93, No.7, pp. 1733-1748, 2024, DOI:10.32604/phyton.2024.052739
    (This article belongs to the Special Issue: Recent Research Trends in Genetics, Genomics, and Physiology of Crop Plants)
    Abstract Twenty-four rice genotypes were examined to assess genetic variability, heritability, and correlations for seven-grain quality traits, eight nutritional elements, and protein. ANOVA revealed significant differences for the quality traits studied. For every trait under study, the phenotypic coefficient of variation was higher than the correspondence genotypic coefficient of variation. Heritability in a broad sense varied from 29.75% for grain length to 98.31% for the elongation trait. Hulling percentage recovery had a highly significant positive correlation with milling and head rice percentage. Consequently, milling percentage had a highly positive correlation with head rice percentage. In amylose… More >

    Comparative and Phylogenetic Analysis of the Complete Chloroplast Genomes of 19 Species in Rosaceae Family

    Riwa Mahai, Rongpeng Liu, Xiaolang Du, Zejing Mu, Xiaoyun Wang, Jun Yuan
    Phyton-International Journal of Experimental Botany, Vol.93, No.6, pp. 1203-1219, 2024, DOI:10.32604/phyton.2024.051559

    Abstract Rosaceae represents a vast and complex group of species, with its classification being intricate and contentious. The taxonomic placement of many species within this family has been a subject of ongoing debate. The study utilized the Illumina platform to sequence 19 plant species from 10 genera in the Rosaceae. The cp genomes, varying in size from 153,366 to 159,895 bp, followed the typical quadripartite organization consisting of a large single-copy (LSC) region (84,545 to 87,883 bp), a small single-copy (SSC) region (18,174 to 19,259 bp), and a pair of inverted repeat (IR) regions (25,310 to… More >

    Abstract The cytokinin oxidase/dehydrogenase (CKX) enzyme is essential for controlling the fluctuating levels of endogenous cytokinin (CK) and has a significant impact on different aspects of plant growth and development. Nonetheless, there is limited knowledge about CKX genes in tomato (Solanum lycopersicum L.). Here we performed genome-wide identification and analysis of nine SlCKX family members in tomatoes using bioinformatics tools. The results revealed that nine SlCKX genes were unevenly distributed on five chromosomes (Chr.1, Chr.4, Chr.8, Chr.10, and Chr.12). The amino acid length, isoelectric points, and molecular weight of the nine SlCKX proteins ranged from 453 to 553, 5.77… More >
