A complete pathway towards improving drought tolerance in rice by discovering candidate genes is illustrated (Figure 2) and briefly described in this paper and includes (i) selecting a specific environment, (ii) creating controlled populations by selecting germplasm adapted to the target environment, (iii) describing the morphological, molecular, and physiological mechanisms involved in the tolerance of the parents, and (iv) integrating this information into models used for QTL analysis and positional cloning (Figure 2). several techniques or approaches, or a comprehensive review paper with concise and precise updates on the latest Singh R., Singh Y., Xalaxo S., et al. A., et al. Two QTLs, qDTY 3.2 and qDTY 12.1 , with large effects on grain yield under drought were identified in the Sabitri background in separate QTL mapping studies. All the improved hybrids (7A/R3-1 and 5A/R3-1) showed moderate resistance to rice blast with disease scores of 3 and 2.5. Molecular breeding for the development of blast and bacterial blight resistance in rice cv. These hybrids are widely grown in arid areas in southern China. Several SNP chips have been developed based on genome sequence information and are available for large-scale genotyping. Co-expression of the stress-inducible zinc finger homeodomain ZFHD1 and NAC transcription factors enhances expression of the ERD1 gene in Arabidopsis. interesting to authors, or important in this field. Rafalski J. PubMed Therefore, CBB23 was used as the donor parent for MAS. This is mainly due to the utilization of semi-dwarf breeding and the development of hybrid rice [2].

Drought Resistance in Rice from Conventional to Molecular Breeding: A Review Drought is the leading threat to agricultural food production, especially in the cultivation of rice, a semi-aquatic plant. Woldesemayat AA, Modise DM, Gemeildien J, Ndimba BK, Christoffels A. PLoS One. Feature Among various metabolic processes, photosynthesis is a vital complex process during drought stress. These candidate genes include a large family of genes expressed under drought stress. Tran L.-S. P., Nakashima K., Sakuma Y., et al. To this end, the current review focuses on reported work on mechanisms and some effects of drought stress on rice yield, as well as management strategies to overcome the effects of drought on rice. Chamarthi S., Kumar A., Vuong T., et al. Liu W.Q., Fan Y.Y., Chen J., Shi Y.F., Wu J.L. Hanhui3 and the NIL and its derived hybrids were grown in fields at the Shanghai Agrobiological Gene Center (Shanghai, China) and were screened for their resistance against BB via the artificial clip inoculation method. Drought stress strongly affects the quantity and quality of plant growth through three main steps (Figure 1). Please enable it to take advantage of the complete set of features! Developing Drought Tolerant Crops Conventional breeding requires the identification of genetic variability to drought among crop varieties, or among sexually compatible species, and introducing this tolerance into lines with suitable agronomic characteristics. Rice (Oryza sativa L.), the major staple food crop of the world, faces a severe threat from widespread drought. volume3,pages 3240 (2014)Cite this article. A co-dominant sequence-tagged site (STS), marker PB9-1, which is linked to the Pi2 gene, was developed for marker-assisted selection (MAS) [15]. Currently, 84 blast resistance genes have been identified, and 24 of these genes (Pb1, Pia, Pib, Pid2, Pid3, Pik, Pi54, Pik-m, Pik-p, Pish, Pit, Pita, Piz-t, Pi1, Pi2, Pi5, Pi2, pi21, Pi25, Pi36, Pi37, Pi56, Pi63, and PiCO39) have been cloned and characterized (http://www.ricedata.cn/gene/gene_pi.htm (accessed on 29 August 2022)). These results demonstrate that the heterozygous and homozygous Pi2 gene in the NIL and its three-line hybrids improved their disease resistance to rice blast. Hoekstra F. A., Golovina E. A., Buitink J. Saddique M. A., Ali Z., Khan A. S., Rana I. View chapter Purchase book published in the various research areas of the journal. The new PMC design is here! Therefore, it is necessary to develop new cultivars with resistance to both biotic and abiotic stressors. This review describes advances in breeding for aroma and drought tolerance in rice and investigates the possibility of combing these traits in one variety . The hybrid 5A/R3-1 exhibited blast and BB resistance, as well as the highest yield among the investigated hybrids. Federal government websites often end in .gov or .mil. The improved NIL, R3-1, showed moderate resistance to rice blast with a disease score of 3.5. Interdisciplinary researchers have been attempting to dissect and comprehend the mechanisms of plant tolerance to drought stress using various methods; however, the limited success of molecular breeding and physiological approaches suggests that we rethink our strategies. These results demonstrate that the NIL and its derived three-line hybrids showed improved disease resistance to BB. New advances in marker development, sequencing, and genomic analysis have provided the opportunity to reconsider the method of creating populations suitable for analysis and to challenge the precise players in drought tolerance. However, many studies have shown that the grain yield of these cultivars may not be sufficient to meet demand [143]; (ii) expression of physiological ideotypes for rice under drought to improve yield, then identifying sources of variation for these traits to introduce into selected varieties: in other words, genomics, breeding, and physiology approaches are integrated to improve drought tolerance in rice [144]. Hybrids derived from the improved NIL showed no significant differences compared with the hybrids derived from the recurrent parent, Hanhui3, in traits such as days to 50% flowering, plant height, no. Yuan L.P. The results of the drought resistance identification show that there were no significant differences in traits between Hanhui3 and the NIL under drought conditions. There are various platforms that can be applied for transcriptional profiling, including PCR-based differential display PCR (DDRT-PCR) [110], cDNA-amplified fragment length polymorphism (cDNA-AFLP) [111], cDNA and suppression subtractive hybridization (SSH) [112], cDNA and oligonucleotide microarrays [113], and digital expression analysis based on EST counts [114]. Additionally, miRNAs have been demonstrated to be involved in drought responses and tolerance in many crop plants, such as soybean and rice, and can improve drought tolerance in plants [109]. The schematic pathway from selection of parental lines to gene identified. Foley J. After the rice was transplanted, intermittent irrigation was applied in the rice fields. Linked markers for foreground selection of Pi2, xa5, and Xa23 genes. Konopka-Postupolska D., Clark G., Goch G., et al. Identification of novel soybean microRNAs involved in abiotic and biotic stresses. Breeding high-yielding drought-tolerant rice: genetic variations and Compared with phenotypic selection, GS selection can reduce the selection time for most traits and has emerged as an important method to predict genotype performance. Gu J.-F., Qiu M., Yang J.-C. Interestingly, the lesion length of the BB of the recurrent parent Hanhui3 was significantly longer than those of the derived hybrids.

Takahashi T., Kakehi J.-I. Regardless, marker-assisted breeding is not a perfect tool because it is effective only with major QTLs; hence, minor QTLs would be underrepresented in the selection process, resulting in missed genetic gains. Epub 2013 May 20. In the present research programme, the stress responsive genes were identified within the QTLs associated with drought tolerance. (7,11,13,14) recent studies on intertissue and interorgan signaling in plant stress responses and adaptation are also When this NIL was crossed with the CMS lines 7A and 5A, the hybrids (heterogeneous genotypes with resistance loci) showed a similar disease resistance to the homologous NIL.
