Leaf morphology related genes revealed by integrating Pan-transcriptome, GWAS and eQTL analyses in a Liriodendron population.

Leaf plays an indispensable role in plant development and growth. Although many known genes related to leaf morphology development have been identified, elucidating the complex genetic basis of leaf morphological traits remains a challenge. Liriodendron plants are common ornamental trees due to their unique leaf shapes, while the molecular mechanism underlying Liriodendron leaf morphogenesis has remained unknown.

Comprehensive deciphering the alternative splicing patterns involved in leaf morphogenesis of Liriodendron chinense.

Alternative splicing (AS), a pivotal post-transcriptional regulatory mechanism, profoundly amplifies diversity and complexity of transcriptome and proteome. Liriodendron chinense (Hemsl.) Sarg.

Genome-wide association study of multiyear dynamic growth traits in hybrid Liriodendron identifies robust genetic loci associated with growth trajectories.

The genetic factors underlying growth traits differ over time points or stages. However, most current studies of phenotypes at single time points do not capture all loci or explain the genetic differences underlying growth trajectories. Hybrid Liriodendron exhibits obvious heterosis and is widely cultivated, although its complex genetic mechanism underlying growth traits remains unknown.

Genome-wide identification of genes in and functional characterization of .

is a relic tree species of the family Magnoliaceae with multiple uses in timber production, landscape decoration, and afforestation. often experiences drought stress in arid areas. However, the molecular basis underlying the drought response of remains unclear.

Overexpression of the gene in alters the cotyledon morphology and increases rosette leaf number.

Background: The unique 'mandarin jacket' leaf shape is the most famous trait of and this characteristic gives aesthetic and landscaping value. However, the underlying regulatory mechanism of genes involved in the leaf development of has remained unclear.

Methods: Based on transcriptome data of leaves at different developmental stages from , we identified differentially expression genes (DEGs) functioning in leaf development.

Transcriptomic profiling of the floral fragrance biosynthesis pathway of Liriodendron and functional characterization of the LtuDXR gene.

Floral fragrance, which has the function of attracting pollinators, is a class of volatile secondary metabolites mainly released by the secretory tissue of petals. Terpenoids are key components of floral volatile substances. Previous studies have shown that there are significant differences in the concentration and composition of volatile floral fragrances, especially terpenoids, between Liriodendron chinense and L.

Genetic divergence and local adaptation of Liriodendron driven by heterogeneous environments.

Ecological adaptive differentiation alters both the species diversity and intraspecific genetic diversity in forests, thus affecting the stability of forest ecosystems. Therefore, knowledge of the genetic underpinnings of the ecological adaptive differentiation of forest species is critical for effective species conservation. In this study, single-nucleotide polymorphisms (SNPs) from population transcriptomes were used to investigate the spatial distribution of genetic variation in Liriodendron to assess whether environmental variables can explain genetic divergence.

Genome-wide survey and identification of AP2/ERF genes involved in shoot and leaf development in Liriodendron chinense.

Background: Liriodendron chinense is a distinctive ornamental tree species due to its unique leaves and tulip-like flowers. The discovery of genes involved in leaf development and morphogenesis is critical for uncovering the underlying genetic basis of these traits. Genes in the AP2/ERF family are recognized as plant-specific transcription factors that contribute to plant growth, hormone-induced development, ethylene response factors, and stress responses.

Genome-Wide Identification and Expression Analysis of Family Genes Associated with Petal Pigment Synthesis in .

The MYB transcription factor family is one of the largest families in plants, and its members have various biological functions. genes are involved in the synthesis of pigments that yield petal colors. plants are widely cultivated as ornamental trees owing to their peculiar leaves, tulip-like flowers, and colorful petals.

Isolation, expression, and functional analysis of the geranylgeranyl pyrophosphate synthase (GGPPS) gene from Liriodendron tulipifera.

Terpenoids are important secondary metabolites in plants and are involved in stress responses and pollinator attraction. Geranylgeranyl pyrophosphate synthase (GGPPS) is a key synthase in the 2C-methyl-D-erythritol-4-phosphate (MEP) pathway of terpenoid synthesis, catalyzing the synthesis of diterpenoids. Liriodendron tulipifera is a nectar plant in North America.

Alternative Splicing Enhances the Transcriptome Complexity of .

Alternative splicing (AS) plays pivotal roles in regulating plant growth and development, flowering, biological rhythms, signal transduction, and stress responses. However, no studies on AS have been performed in , a deciduous tree species that has high economic and ecological value. In this study, we used multiple tools and algorithms to analyze transcriptome data derived from seven tissues hybrid sequencing.

Cloning, Characterization and Functional Analysis of the Gene, a Homologue of Derived from .

Flower colour and colour patterns are crucial traits for ornamental species; thus, a comprehensive understanding of their genetic basis is extremely significant for plant breeders. The tulip tree ( Linn.) is well known for its flowers, odd leave shape and tree form.
