A high-throughput phenotyping assay for precisely determining stalk crushing strength in large-scale sugarcane germplasm. FRONTIERS IN PLANT SCIENCE 2023; 14:1224268. [PMID: 37546250 PMCID: PMC10399216 DOI: 10.3389/fpls.2023.1224268] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Accepted: 07/04/2023] [Indexed: 08/08/2023]
Abstract
Sugarcane is a major industrial crop around the world. Lodging due to weak mechanical strength is one of the main problems leading to huge yield losses in sugarcane. However, due to the lack of high efficiency phenotyping methods for stalk mechanical strength characterization, genetic approaches for lodging-resistant improvement are severely restricted. This study attempted to apply near-infrared spectroscopy high-throughput assays for the first time to estimate the crushing strength of sugarcane stalks. A total of 335 sugarcane samples with huge variation in stalk crushing strength were collected for online NIRS modeling. A comprehensive analysis demonstrated that the calibration and validation sets were comparable. By applying a modified partial least squares method, we obtained high-performance equations that had large coefficients of determination (R2 > 0.80) and high ratio performance deviations (RPD > 2.4). Particularly, when the calibration and external validation sets combined for an integrative modeling, we obtained the final equation with a coefficient of determination (R2) and ratio performance deviation (RPD) above 0.9 and 3.0, respectively, demonstrating excellent prediction capacity. Additionally, the obtained model was applied for characterization of stalk crushing strength in large-scale sugarcane germplasm. In a three-year study, the genetic characteristics of stalk crushing strength were found to remain stable, and the optimal sugarcane genotypes were screened out consistently. In conclusion, this study offers a feasible option for a high-throughput analysis of sugarcane mechanical strength, which can be used for the breeding of lodging resistant sugarcane and beyond.

The positive feedback regulatory loop of miR160-Auxin Response Factor 17-HYPONASTIC LEAVES 1 mediates drought tolerance in apple trees. PLANT PHYSIOLOGY 2022; 188:1686-1708. [PMID: 34893896 PMCID: PMC8896624 DOI: 10.1093/plphys/kiab565] [Citation(s) in RCA: 22] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Accepted: 11/10/2021] [Indexed: 05/25/2023]
Abstract
Drought stress tolerance is a complex trait regulated by multiple factors. Here, we demonstrate that the miRNA160-Auxin Response Factor 17 (ARF17)-HYPONASTIC LEAVES 1 module is crucial for apple (Malus domestica) drought tolerance. Using stable transgenic plants, we found that drought tolerance was improved by higher levels of Mdm-miR160 or MdHYL1 and by decreased levels of MdARF17, whereas reductions in MdHYL1 or increases in MdARF17 led to greater drought sensitivity. Further study revealed that modulation of drought tolerance was achieved through regulation of drought-responsive miRNA levels by MdARF17 and MdHYL1; MdARF17 interacted with MdHYL1 and bound to the promoter of MdHYL1. Genetic analysis further suggested that MdHYL1 is a direct downstream target of MdARF17. Importantly, MdARF17 and MdHYL1 regulated the abundance of Mdm-miR160. In addition, the Mdm-miR160-MdARF17-MdHYL1 module regulated adventitious root development. We also found that Mdm-miR160 can move from the scion to the rootstock in apple and tomato (Solanum lycopersicum), thereby improving root development and drought tolerance of the rootstock. Our study revealed the mechanisms by which the positive feedback loop of Mdm-miR160-MdARF17-MdHYL1 influences apple drought tolerance.

Priming by High Temperature Stress Induces MicroRNA Regulated Heat Shock Modules Indicating Their Involvement in Thermopriming Response in Rice. Life (Basel) 2021; 11:life11040291. [PMID: 33805566 PMCID: PMC8067039 DOI: 10.3390/life11040291] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 03/08/2021] [Accepted: 03/11/2021] [Indexed: 01/09/2023] Open
Abstract
Rice plants often encounter high temperature stress, but the associated coping strategies are poorly understood. It is known that a prior shorter exposure to high temperature, called thermo-priming, generally results in better adaptation of the plants to subsequent exposure to high temperature stress. High throughput sequencing of transcript and small RNA libraries of rice seedlings primed with short exposure to high temperature followed by high temperature stress and from plants exposed to high temperature without priming was performed. This identified a number of transcripts and microRNAs (miRs) that are induced or down regulated. Among them osa-miR531b, osa-miR5149, osa-miR168a-5p, osa-miR1846d-5p, osa-miR5077, osa-miR156b-3p, osa-miR167e-3p and their respective targets, coding for heat shock activators and repressors, showed differential expression between primed and non-primed plants. These findings were further validated by qRT-PCR. The results indicate that the miR-regulated heat shock proteins (HSPs)/heat shock transcription factors (HSFs) may serve as important regulatory nodes which are induced during thermo-priming for plant survival and development under high temperatures.

Current breeding and genomic approaches to enhance the cane and sugar productivity under abiotic stress conditions. 3 Biotech 2020; 10:440. [PMID: 33014683 PMCID: PMC7501393 DOI: 10.1007/s13205-020-02416-w] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Accepted: 08/28/2020] [Indexed: 01/07/2023] Open
Abstract
Sugarcane (Saccharum spp.) crop is vulnerable to many abiotic stresses such as drought, salinity, waterlogging, cold and high temperature due to climate change. Over the past few decades new breeding and genomic approaches have been used to enhance the genotypic performance under abiotic stress conditions. In sugarcane, introgression of genes from wild species and allied genera for abiotic stress tolerance traits plays a significant role in the development of several stress-tolerant varieties. Moreover, the genomics and transcriptomics approaches have helped to elucidate the key genes/TFs and pathways involved in abiotic stress tolerance in sugarcane. Several novel miRNAs families /proteins or regulatory elements that are responsible for drought, salinity, and cold tolerance have been identified through high-throughput sequencing. The existing sugarcane monoploid genome sequence information opens new gateways and opportunities for researchers to improve the desired traits through efficient genome editing tools, such as the clustered regularly interspaced short palindromic repeat-Cas (CRISPR/Cas) system. TALEN mediated mutations in a highly conserved region of the caffeic acid O-methyltransferase (COMT) of sugarcane significantly reduces the lignin content in the cell wall which is amenable for biofuel production from lignocellulosic biomass. In this review, we focus on current breeding with genomic approaches and their substantial role in enhancing cane production under the abiotic stress conditions, which is expected to provide new insights to plant breeders and biotechnologists to modify their strategy in developing stress-tolerant sugarcane varieties, which can highlight the future demand of cane, bio-energy, and viability of sugar industries.
