Published: Jan. 17, 2025

ABSTRACT Plant oils play a crucial role in human nutrition, industrial applications and biofuel production. While the enzymes involved fatty acid (FA) biosynthesis are well‐studied, regulatory networks governing these processes remain largely unexplored. This review explores intricate modulating seed oil biosynthesis, focusing on key pathways factors. Seed content is determined by efficiency of de novo FA synthesis as well influenced sugar transport, lipid metabolism, inhibitors fine‐tuning mechanisms. At center this network WRINKLED1 (WRI1), which plays conserved promoting across various plant species. WRI1 interacts with multiple proteins, its expression level regulated upstream regulators, including members LAFL network. Beyond network, we also discuss potential nuclear factor‐Y (NF‐Y) soybean an emphasis NF‐YA NF‐YB their associated proteins. NF‐Y represents promising avenue for future efforts aimed at enhancing accumulation improving stress tolerance soybean. Additionally, application omics‐based approaches great significance. Advances omics technologies have greatly facilitated identification gene resources, opening new opportunities genetic improvement. Importantly, several transcription factors participate responses, highlighting link between two processes. comprehensive elucidates complex mechanisms underlying regulation offering insights into biotechnological strategies production crops.

NRAMP gene family in Kandelia obovata: genome-wide identification, expression analysis, and response to five different copper stress conditions

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 14

Published: Jan. 4, 2024

Natural resistance-associated macrophage proteins (NRAMPs) are a class of metal transporters found in plants that exhibit diverse functions across different species. Transporter facilitate the absorption, distribution, and sequestration metallic elements within various plant tissues. Despite extensive identification NRAMP family genes species, full analysis these tree species is still necessary. Genome-wide bioinformatics were performed to understand roles copper (CuCl2) stress Kandelia obovata (Ko). In Arachis hypogaea L., Populus trichocarpa, Vitis vinifera, Phaseolus vulgaris Camellia sinensis, Spirodela polyrhiza, Glycine max L. Solanum lycopersicum, genome-wide study gene was earlier.The domain 3D structural variation, phylogenetic tree, chromosomal distributions, structure, motif analysis, subcellular localization, cis-regulatory elements, synteny duplication expression profiles leaves CuCl2 all investigated this research. order comprehend notable obovata, comprehensive investigation conducted at genomic level. This successfully five genes, encompassing one pair resulting from wholegenome had undergone segmental duplication. The examination position revealed an unequal distribution KoNRAMP chromosomes 1, 2, 5, 7, 18. KoNRAMPs can be classified into three subgroups (I, II, SLC) based on phylogeny analyses, similar lycopersicum.

Effect of Partial Elimination of Mitochondrial DNA on Genome-Wide Identified AOX Gene Family in Chlamydomonas reinhardtii

Processes, Journal Year: 2024, Volume and Issue: 12(8), P. 1654 - 1654

Published: Aug. 7, 2024

Using Chlamydomonas as a model organism, we attempted to eliminate mitochondrial DNA (mtDNA) similar rho0 or rho− cells (completely partially mtDNA-eliminated cells) in yeast. We successfully generated named crm- cells, causing the inactivation of activity. used three different chemicals mtDNA including acriflavine (AF), ethidium bromide (EB) and dideoxycytidine (ddC) which prevents replication, inhibits POLG (DNA polymerase gamma) terminates chain, respectively. The qPCR method was detect copy number selected rrnL6 gene for detection mitochondria, well CC-124 strain. A reduction led higher expression AOX1, UCP1, PGRL1 ICL1, indicates disturbance mitochondria–chloroplast ATP NADPH balance. AOX genes further study this family carried out genome-wide search identify green algae (C. reinhardtii). Our results revealed that C. reinhardtii contains four genes, i.e., CrAOX1, CrAOX2, CrAOX3 CrAOX4, are distributed on Chr 3, Chr7 Chr9. All CrAOX were predicted localize mitochondria using bioinformatics tools. Phylogenetic analysis suggests these CrAOXs subdivided into groups existing same group could perform identical functions. Collinearity describes strong evolutionary relationships AOXs between unicellular multicellular Volvox carteri. GO (gene ontology) annotation played an integral part carrying alternate oxidative respirative activities. Three putative miRNAs, cre-miR1162-3p, cre-miR1171 cre-miR914, targeting CrAOX2 identified. studies have laid foundation use elucidating functional characteristics family.

Copper-containing amine oxidases (CuAOs) are known to have significant involvement in the process of polyamine catabolism, as well serving crucial functions plant development and response abiotic stress. A genome-wide investigation CuAO protein family was previously carried out sweet orange (Citrus sinensis) cherry (Prunus avium L.). Six (KoCuAO1-KoCuAO6) genes were discovered for first time Kandelia obovata (Ko) genome through a analysis conducted better understand key roles gene obovata. This study encompassed an into various aspects analysis, including characterization identification, subcellular localization, chromosomal distributions, phylogenetic tree structure motif duplication cis-regulatory element domain 3D structural variation expression profiling leaves under five different treatments copper (CuCl2). Phylogenetic suggests that these KoCuAOs, like cherry, may be subdivided three subgroups.
