Formation mechanism and regulation analysis of trumpet leaf in L.

Introduction: The research on plant leaf morphology is of great significance for understanding the development and evolution of plant organ morphology. As a relict plant, the leaf morphology typically exhibits bifoliate and peltate forms. However, throughout its long evolutionary history, Ginkgo leaves have undergone diverse changes.

Transcriptome and metabolome analyses of lignin biosynthesis mechanism of .

Background: , as an important plant for ecological protection, is a pioneer tree species for afforestation in arid and barren mountainous areas. Lignin has the functions of water and soil conservation, strengthening plant mechanical strength and resisting adverse environmental effects and plays an important role in the ecological protection benefits of .

Methods: In this study, annual dynamic observations of the lignin content in roots, stems and leaves of one-year-old seedlings of a half-sib family were carried out, and combined transcriptome and metabolome analyses were carried out during three key stages of stem development.

Multi-omics analysis reveals the ontogenesis of basal chichi in Ginkgo biloba L.

Chichi is a unique biological phenomenon observed in Ginkgo biloba L.. In this study, multi-omics analysis was used to compare basal chichi (C) with roots (R) and stems (S) to explore the regulatory mechanisms of basal chichi ontogenesis.

Transcriptome profile analysis reveals the ontogenesis of rooted chichi in Ginkgo biloba L.

The Ginkgo biloba L. chichi is a unique organ. To explore the molecular mechanisms underlying the ontogenesis of G.

Transcriptome sequencing of active buds from Populus deltoides CL. and Populus × zhaiguanheibaiyang reveals phytohormones involved in branching.

Branching in woody plants affects their ecological benefits and impacts wood formation. To obtain genome-wide insights into the transcriptome changes and regulatory mechanisms associated with branching, we performed high-throughput RNA sequencing to characterize cDNA libraries generated from active buds of Populus deltoides CL. 'zhonglin2025' (BC) and Populus × zhaiguanheibaiyang (NC).

Transcriptome Profile Analysis from Different Sex Types of Ginkgo biloba L.

In plants, sex determination is a comprehensive process of correlated events, which involves genes that are differentially and/or specifically expressed in distinct developmental phases. Exploring gene expression profiles from different sex types will contribute to fully understanding sex determination in plants. In this study, we conducted RNA-sequencing of female and male buds (FB and MB) as well as ovulate strobilus and staminate strobilus (OS and SS) of Ginkgo biloba to gain insights into the genes potentially related to sex determination in this species.

Identification and Characterization of MicroRNAs in Ginkgo biloba var. epiphylla Mak.

Ginkgo biloba, a dioecious plant known as a living fossil, is an ancient gymnosperm that stands distinct from other gymnosperms and angiosperms. Ginkgo biloba var. epiphylla (G.

[Research on systematic evolution of ginkgo biloba based on chemical composition of wood].

In the present article, the authors mensurated the infrared spectra of 22 conifer and broadleaf trees such as ginkgo biloba L., cycas revoluta thunb., Populus tomentosa Carr and so on using FTIR, analyzed the difference of a number of absorb peaks in fingerprint area, the characteristic absorb peak position of cellulose and lignin of these trees and their alternation regulations of relative intensity, then discussed the evolutional issue of ginkgo biloba.

[Quantitative genetic analysis and multiple trait selection of pharmaceutical composition on Ginkgo biloba L. leaves].

The China possesses more than 70% Ginkgo resources in the world. The purposes of this research are to collect fine seedling and grafting clones in China, to probe genetic law on flavone glycosides and terpenes on Ginkgo leaves, and select leaf-used cultivars of high-pharmaceutical composition. In this research, we have collected 87 clones from 13 provenances and have carried out randomized block experiment at Tancheng, Laizhou and Yaoxiang in Shandong Province.
