ECE-CYC1 Transcription Factor CmCYC1a May Interact with CmCYC2 in Regulating Flower Symmetry and Stamen Development in .

Background: The attractive inflorescence of , its capitulum, is always composed of ray (female, zygomorphy) and disc (bisexual, actinomorphy) florets, but the formation mechanism remains elusive. The gene diversification pattern of the ECE (CYC/TB1) clade has been speculated to correlate with the capitulum. Within the three subclades of ECE, the involvement of CYC2 in defining floret identity and regulating flower symmetry has been demonstrated in many species of Asteraceae, including .

The PopbZIP2-PopMYB4 regulatory module enhances disease resistance in poplars by modulating proanthocyanidin accumulation.

Anthracnose, caused by Colletotrichum gloeosporioides, is a significant fungal disease that affects poplar trees globally, leading to reduced yields and substantial economic losses. Proanthocyanidins (PAs) play a key role in resistance to fungal pathogens; however, the mechanisms by which PAs mediate resistance to anthracnose in poplar remain poorly understood. In this study, we identified PopbZIP2, a transcription factor-encoding gene that was initially expressed in infected leaves and subsequently in uninfected leaves in response to C.

[Population structure and fruiting ability of ].

We analyzed age structure and dynamics, spatial distribution patterns, and reproductive capabilities of four populations in Xinjiang, to evaluate the survival status of the species and explore the reasons behind its endangerment. The results showed that the populations had fewer individuals in the youngest (Ⅰ) and oldest (Ⅵ-Ⅷ) age classes, with a predominance of middle-aged individuals, resulting in an irregular pyramid-shaped distribution, described as "high in the middle, low on both sides". The populations were generally growing, but were susceptible to external environmental disturbances (＞0, ＞0).

A 49-bp deletion of results in a double flower phenotype in .

The double flower is an important trait with substantial ornamental value. While mutations in TOE-type or () genes play a crucial role in enhancing petal number in ornamental plants, the complete mechanism underlying the formation of double flowers remains to be fully elucidated. Through the application of bulked segregant analysis (BSA), we identified a novel gene, (), characterized by a 49-bp deletion in double-flowered .

'Zhizhang Guhong Chongcui' is a new cultivar of with cross-cultivar group characteristics. It has typical characteristics of cinnabar purple cultivar group and green calyx cultivar group. It has green calyx, white flower, and light purple xylem, but the mechanism remains unclear.

Genome-Wide Identification of Callose Synthase Family Genes and Their Expression Analysis in Floral Bud Development and Hormonal Responses in .

Callose is an important polysaccharide composed of beta-1,3-glucans and is widely implicated in plant development and defense responses. Callose synthesis is mainly catalyzed by a family of callose synthases, also known as glucan synthase-like (GSL) enzymes. Despite the fact that GSL family genes were studied in a few plant species, their functional roles have not been fully understood in woody perennials.

Integrative Analysis of Metabolome and Transcriptome Revealed Lutein Metabolism Contributed to Yellow Flower Formation in .

is a famous ornamental woody tree with colorful flowers. with yellow flowers is one of the most precious varieties. Regretfully, metabolites and regulatory mechanisms of yellow flowers in are still unclear.

Phylogeny of Gene Family and Expression Analysis of Flower Coloration and Stress Response in .

The gene family plays a crucial role in the cleavage of carotenoids, converting them into apocarotenoids. This process not only impacts the physiology and development of plants but also enhances their tolerance toward different stresses. However, the character of the gene family and its role in ornamental woody remain unclear.

Genome assembly and resequencing analyses provide new insights into the evolution, domestication and ornamental traits of crape myrtle.

Crape myrtle () is a globally used ornamental woody plant and is the representative species of . However, studies on the evolution and genomic breeding of have been hindered by the lack of a reference genome. Here we assembled the first high-quality genome of using PacBio combined with Hi-C scaffolding to anchor the 329.

The Secrets of Meristems Initiation: Axillary Meristem Initiation and Floral Meristem Initiation.

The branching phenotype is an extremely important agronomic trait of plants, especially for horticultural crops. It is not only an important yield character of fruit trees, but also an exquisite ornamental trait of landscape trees and flowers. The branching characteristics of plants are determined by the periodic initiation and later development of meristems, especially the axillary meristem (AM) in the vegetative stage and the floral meristem (FM) in the reproductive stage, which jointly determine the above-ground plant architecture.
