Abstract
Background Early maturity in spring bread wheat is highly desirable in the regions where it enables the plants to evade high temperatures and plant pathogens at the end of the growing season. Methods To reveal the genetic loci responsible for the maturity time association analysis was carried out based on phenotyping for an 11-year period and high-throughput SNP genotyping of a panel of the varieties contrasting for this trait. The expression of candidate genes was verified using qPCR. The association between the SNP markers and the trait was validated using the biparental F2:3 population. Results Our data showed that under long-day conditions, the period from seedling to maturity is mostly influenced by the time from heading to maturity, rather than the heading time. The QTLs associated with the trait were located on 2A, 3B, 4A, 5B, 7A and 7B chromosomes with the 7BL locus being the most significant and promising for its SNPs accelerated the maturity time by about 9 days. Gene dissection in this locus detected a number of candidates, the best being TraesCS7B02G391800 (bZIP9) and TraesCS7B02G412200 (photosystem II reaction center). The two genes are predominantly expressed in the flag leaf while flowering. The effect of the SNPs was verified in F2:3 population and confirmed the association of the 4A, 5B and 7BL loci with the maturity time.

Salmonella typhimurium detection and ablation using OmpD specific aptamer with non-magnetic and magnetic graphene oxide. Biosens Bioelectron 2023; 234:115354. [PMID: 37126873 DOI: 10.1016/j.bios.2023.115354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 04/25/2023] [Accepted: 04/25/2023] [Indexed: 05/03/2023]
Abstract
Foodborne diseases have increased in the last few years due to the increased consumption of packaged and contaminated food. Major foodborne bacteria cause diseases such as diarrhea, vomiting, and sometimes death. So, there is a need for early detection of foodborne bacteria as pre-existing detection techniques are time-taking and tedious. Aptamer has gained interest due to its high stability, specificity, and sensitivity. Here, aptamer has been developed against Salmonella Typhimurium through the Cell-Selex method, and to further find the reason for specificity and sensitivity, OmpD protein was isolated, and binding studies were done. Single molecular FRET experiment using aptamer and graphene oxide studies has also been done to understand the mechanism of FRET and subsequently used for target bacterial detection. Using this assay, Salmonella Typhimurium can be detected up to 10 CFU/mL. Further, Magnetic Graphene oxide was used to develop an assay to separate and ablate bacteria using 808 nm NIR where temperature increase was more than 60 °C within 30 s and has been shown by plating as well as a confocal live dead assay. Thus, using various techniques, bacteria can be detected and ablated using specific aptamer and Graphene oxide.

Wang H, Zhang Y, Norris A, Jiang CZ. S1-bZIP Transcription Factors Play Important Roles in the Regulation of Fruit Quality and Stress Response. FRONTIERS IN PLANT SCIENCE 2022; 12:802802. [PMID: 35095974 PMCID: PMC8795868 DOI: 10.3389/fpls.2021.802802] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Accepted: 12/20/2021] [Indexed: 06/14/2023]
Abstract
Sugar metabolism not only determines fruit sweetness and quality but also acts as signaling molecules to substantially connect with other primary metabolic processes and, therefore, modulates plant growth and development, fruit ripening, and stress response. The basic region/leucine zipper motif (bZIP) transcription factor family is ubiquitous in eukaryotes and plays a diverse array of biological functions in plants. Among the bZIP family members, the smallest bZIP subgroup, S1-bZIP, is a unique one, due to the conserved upstream open reading frames (uORFs) in the 5' leader region of their mRNA. The translated small peptides from these uORFs are suggested to mediate Sucrose-Induced Repression of Translation (SIRT), an important mechanism to maintain sucrose homeostasis in plants. Here, we review recent research on the evolution, sequence features, and biological functions of this bZIP subgroup. S1-bZIPs play important roles in fruit quality, abiotic and biotic stress responses, plant growth and development, and other metabolite biosynthesis by acting as signaling hubs through dimerization with the subgroup C-bZIPs and other cofactors like SnRK1 to coordinate the expression of downstream genes. Direction for further research and genetic engineering of S1-bZIPs in plants is suggested for the improvement of quality and safety traits of fruit.

Differentially expressed bZIP transcription factors confer multi-tolerances in Gossypium hirsutum L. Int J Biol Macromol 2020; 146:569-578. [PMID: 31923491 DOI: 10.1016/j.ijbiomac.2020.01.013] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2019] [Revised: 01/01/2020] [Accepted: 01/03/2020] [Indexed: 12/23/2022]
Abstract
Basic leucine zipper (bZIP) transcription factor plays an important role in various biological processes, such as response to biotic and abiotic stresses. In this study we performed a systematic investigation and analysis of bZIP gene family in Gossypium hirsutum to predict their functions in response to different abiotic stresses. A total of 207 bZIP genes were identified from Gossypium hirsutum genome and classified into 13 subfamilies through phylogenetic analysis, which was testified by the analysis of conserved motifs and exon-intron structures. Annotation of GHbZIPs was performed based on well-studied Arabidopsis bZIPs to speculate the gene function. RNA-seq analysis was conducted to identify the co-expressed and differentially expressed bZIPs under cold, heat, salt and PEG treatments. Promoter analysis and interaction network of GHbZIP proteins demonstrated that ABA-activated signaling pathway was pivotal in the regulation of GHbZIPs, and GHbZIPs involved in ER stress were supposed to function through interaction with other GHbZIPs and ABA pathway. Cis-elements in the upstream and downstream of GHbZIPs interaction network were also discussed. These findings provided us with clues about functions of bZIP in Gossypium hirsutum.
