Dirigent (DIR) proteins are key regulators of lignin and lignan biosynthesis and play critical roles in plant hormone responses, abiotic stress tolerance, and growth and development. This study identified and characterized 47 genes in Moso bamboo, classifying them into three groups. Phylogenetic and comparative analyses revealed strong evolutionary conservation, with the Moso bamboo genes being most closely related to those in rice and maize.

However, its molecular functions remain largely unknown in , which is one of the most economically and ecologically important bamboo species and the most widely distributed one in China. This study identified 17 genes in and classified them into seven subgroups, showing a closer evolutionary relationship to genes from rice.

The CPP gene family of Moso bamboo was identified through bioinformatics, and the structural and functional attributes of the gene, including its physicochemical properties, evolutionary relationships, and gene-protein structures, were revealed. Additionally, the current study also offers valuable information on the patterns of gene expression in bamboo shoots during the period of accelerated development.

The proliferation of vigorous lianas usually forms liana canopies over the crowns of host trees and liana mats on the ground of open areas or large forest gaps. While research on liana canopies has increased significantly in recent decades, our understanding of liana mats remains limited. (Convolvulaceae), a fast-growing liana, forms mature liana mats that can persist for decades, characterized by numerous upright searcher shoots that extend from the liana mats in search of supports.

Herein, an individual peptide nanoparticle encapsulation strategy is proposed via surface adsorption, in which peptide molecules undergo granulation and subsequently aggregate with polymer molecules, forming a network via electrostatic interactions. Under the water phase, surplus polymer molecules dissolve, leading to a single nanoparticle encapsulation with a core-shell structure.

Although 'Shatian' pummelo (Citrus grandis), a traditional cultivated variety, possesses the self-incompatible trait, the role of S-RNases in the self-incompatibility of 'Shatian' pummelo is poorly understood. To identify genes associated with self-incompatibility in citrus, we identified 16 genes encoding homologs of ribonucleases in the genomes of sweet orange (Citrus sinensis) and clementine mandarin (Citrus clementine).

To accelerate the pummelo breeding program, it is essential to obtain extensive genetic information and develop relative molecular markers. Here, we obtained a 12-Gb transcriptome dataset of pummelo through a mixture of RNA from seven tissues using Illumina pair-end sequencing, assembled into 57,212 unigenes with an average length of 1010 bp.
