Summary: Drought stress significantly affects flax plants, causing wilting of leaves and increasing lignin content in fiber flax. The study highlights the rapid responses of flax to drought stress, including morphological, physiological, biochemical, and gene expression changes. These findings provide important evidence for understanding the mechanisms underlying plant response to drought stress.

Summary: This study conducted a systematic genome-wide analysis to identify 587 RING finger genes in flax, classifying them into various categories and groups. These genes were distributed across 15 chromosomes and clustered into three clades based on phylogenetic relationships. The segmental duplicated gene pairs showed a non-synonymous/synonymous substitution ratio of less than 1, indicating negative selection since duplication. Most RING genes in flax exhibited differential expression during seed development or in the shoot apex.

Summary: This study conducted comprehensive genome-wide characterization of the flax WRKY gene family, predicting 102 LuWRKY genes and classifying them into different groups based on structural and phylogenetic features. Expression profiling showed that genes associated with cellulose, hemicellulose, or lignin content were predominantly expressed in stems and roots, while stress response genes were mainly expressed in leaves.

Summary: In this study, nine LuF5H genes were identified from flax genomic data. Bioinformatics analysis revealed the properties, structures, motifs, phylogenetic features, and promoter elements related to these genes. RNA-seq analysis showed that LuF5H3 and LuF5H7 were the main genes involved in flax lignin biosynthesis. Additionally, the expression levels of several LuF5H genes were upregulated under drought, NaCl stress, and brassinosteroid treatment conditions. This study provides valuable data for improving flax fiber quality and reducing manufacturing costs and environmental pollution.

Summary: In this study, 105 WRKY genes were identified in the flax genome, with 26 belonging to group I, 68 to group II, 8 to group III, and 3 to group UN. The WRKY genes showed similarities in gene structure and WRKY motif characteristics within each group. The promoter sequence of WRKY genes contained photoresponsive elements, core regulatory elements, and abiotic stress-related cis-acting elements. The flax WRKY gene family exhibited an even distribution on chromosomes and was mainly concentrated in group I and II. This study provides a foundation for further understanding the evolution and functional analysis of WRKY transcription factors.

Summary: This paper reviews the history, types, research methods, occurrence, and genetic mechanisms of flax breeding, with a focus on apomixis. It discusses the development and genetic mechanisms of apomixis in polyembryonic flax, as well as progress in inducing methods using cytology, embryology, genetics, and molecular biology. The study aims to uncover the rules of apomixis and enhance its utilization efficiency in breeding, while also proposing solutions to existing problems in apomixis breeding of polyembryonic flax and outlining future research directions in flax apomixis.

Summary: The study found that ultrasonic treatment significantly increased lignan content in flax sprouts, particularly secoisolariciresinol diglucoside. It also affected the accumulation of caffeic acid and p-coumaric acid in flax sprouts. Fiber flax sprouts were more sensitive to ultrasonic treatment.

Summary: The study found that under water stress conditions, brown-seeded families had significantly higher heritability and genetic advance for seed yield compared to yellow-seeded families. Additionally, while yellow-seeded families had higher SDG content in non-stress environments, brown-seeded families showed an increase in SDG content under water stress conditions.

Summary: Hydrogen peroxide is an environmentally and economically friendly agent for bleaching flax fibers. It was found that hydrogen peroxide can remove both hemicelluloses and lignin from flax fibers, leading to an increase in fiber whiteness. The correlations between modification conditions and fiber properties allow for tailored utilization of hydrogen peroxide in bleaching and modifying flax fibers.
