Abiotic stress-induced gene expression in pineapple as a potential genetic marker

Advanced Agrochem, Journal Year: 2024, Volume and Issue: 3(2), P. 133 - 142

Published: Jan. 19, 2024

Pineapple, a popular tropical fruit with diverse culinary and health applications, has gained significant attention due to its economic importance, benefits, scientific exploration. Abiotic stress been shown have detrimental effects on physiological aspects of pineapple, such as photosynthesis rate internal browning. However, physical parameters are inadequate in providing accurate assessment, early detection, enabling marker-assisted breeding for pineapple under abiotic stress. Genetic markers provide valuable insights into plant defense mechanisms tolerance, the identification key genes pathways involved. The aim this review was discuss potential genetic reliable tool studying pineapple. It focuses involved response their utility markers, while also discussing changes. responsiveness several gene families, including CPK, CBL, CYS, Dof, TALE, SBP, WRKY, ZIP, R2R3-MYB, DREB, known before. Therefore, harnessing these can yield comprehending effectively managing A comprehensive understanding is essential enhancing agricultural productivity developing stress-resistant varieties.

Genome-wide identification of the class III peroxidase gene family of sugarcane and its expression profiles under stresses

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 14

Published: Jan. 30, 2023

Plant-specific Class III peroxidases (PRXs) play a crucial role in lignification, cell elongation, seed germination, and biotic abiotic stresses.The class peroxidase gene family sugarcane were identified by bioinformatics methods realtime fluorescence quantitative PCR.Eighty-two PRX proteins characterized with conserved domain as members of the R570 STP. The ShPRX genes divided into six groups phylogenetic analysis sugarcane, Saccharum spontaneum, sorghum, rice, Arabidopsis thaliana. promoter cis-acting elements revealed that most contained regulatory involved ABA, MeJA, light responsiveness, anaerobic induction, drought inducibility. An evolutionary indicated ShPRXs was formed after Poaceae Bromeliaceae diverged, tandem duplication events played critical expansion sugarcane. Purifying selection maintained function proteins. SsPRX differentially expressed stems leaves at different growth stages S. spontaneum. However, SCMV-inoculated plants. A qRT-PCR showed SCMV, Cd, salt could specifically induce expression sugarcane.These results help elucidate structure, evolution, functions provide ideas for phytoremediation Cd-contaminated soil breeding new varieties resistant to mosaic disease, salt, Cd stresses.

RNA-seq-based comparative transcriptome analysis reveals the role of CsPrx73 in waterlogging-triggered adventitious root formation in cucumber

Horticulture Research, Journal Year: 2024, Volume and Issue: 11(4)

Published: Feb. 28, 2024

Abstract Abiotic stressors like waterlogging are detrimental to cucumber development and growth. However, comprehension of the highly complex molecular mechanism underlying can provide an opportunity enhance tolerance under stress. We examined hypocotyl stage-specific transcriptomes waterlogging-tolerant YZ026A waterlogging-sensitive YZ106A, which had different adventitious rooting ability waterlogging. performed better stress by altering its antioxidative machinery demonstrated a greater superoxide ion (O 2−) scavenging ability. KEGG pathway enrichment analysis showed that high number differentially expressed genes (DEGs) were enriched in phenylpropanoid biosynthesis. By pairwise comparison weighted gene co-expression network analysis, 2616 DEGs obtained categorized into 11 modules. Amongst modules, black was identified as common module yielded novel key regulatory gene, CsPrx73. Transgenic plants overexpressing CsPrx73 root (AR) formation conditions increase reactive oxygen species (ROS) scavenging. Silencing expression virus-induced silencing adversely affects AR condition. Our results also indicated CsERF7-3, waterlogging-responsive ERF transcription factor, directly bind ATCTA-box motif promoter initiate expression. Overexpression CsERF7-3 enhanced formation. On contrary, CsERF7-3-silenced decreased In conclusion , our study demonstrates CsERF7-3–CsPrx73 allows cucumbers adapt more efficiently promoting production ROS

Class III Peroxidases in the Peach (Prunus persica): Genome-Wide Identification and Functional Analysis

Plants, Journal Year: 2024, Volume and Issue: 13(1), P. 127 - 127

Published: Jan. 2, 2024

Class III peroxidases are plant-specific and play a key role in the response to biotic abiotic stresses, as well plant growth development. In this study, we investigated 60 POD genes from Prunus persica based on genomic transcriptomic data available NCBI analysed expression of individual with qPCR. Peroxidase were clustered into five subgroups using phylogenetic analysis. Their exon–intron structure conserved motifs analysed. Analysis showed that PpPOD varied significantly different tissues, at developmental stages under stress treatments. All divided low- high-expressed genes, most highly expressed identified for tissues (PpPOD12 PpPOD42 flower buds PpPOD73, PpPOD12, PpPOD42, PpPOD31 fruits). The relationship between cold tolerance level peroxidase was revealed. These studies carried out first time peach confirmed chilling may be related specificity antioxidant complex gene expression.
