Abstract

The PIN (PIN-formed) proteins act as vital carriers, regulating auxin polar transport and playing a crucial role in plant growth and development. Cymbidium ensifolium (Orchidaceae) is a perennial herbaceous plant highly esteemed for its high ornamental value. The lotus-shape flowers of C. ensifolium are favored by consumers for their distinctive flower shape with shorter petals. To deepen our understanding of the members and characteristics of PIN gene family in C. ensifolium, this study performed genome-wide identification and analysis of CePIN members, including their physicochemical properties, protein and gene structures, conserved motifs, phylogenetic evolution, promoter components, and expression patterns. The results revealed a total of 16 PIN gene family members in the genome of C. ensifolium. Expression analysis demonstrated significant differential expression of all 16 CePINs across different tissues. Notably, a close correlation was observed between the expression of CePIN1a and CePIN3 and the formation of lotus-shape flowers in C. ensifolium. These findings provide a foundational understanding for further exploration of CePIN functions and offer valuable insights for studying petal development in C. ensifolium.

分析大花蕙兰的 PIN 基因家族发现其在花瓣发育中的潜在功能

PIN 蛋白（PIN-formed）作为重要的载体，调节着植物生长素的极性运输，在植物的生长和发育过程中发挥着至关重要的作用。大花蕙兰（兰科）是一种多年生草本植物，因其极高的观赏价值而备受推崇。大花蕙兰的莲花形状独特，花瓣较短，深受消费者青睐。为了加深对莲形草中 PIN 基因家族成员及其特征的了解，本研究对莲形草中的 PIN 基因成员进行了全基因组鉴定和分析，包括其理化性质、蛋白质和基因结构、保守基序、系统进化、启动子成分和表达模式。结果表明，C. ensifolium 基因组中共有 16 个 PIN 基因家族成员。表达分析表明，所有 16 个 CePIN 在不同组织中都有明显的表达差异。值得注意的是，CePIN1a 和 CePIN3 的表达与莲花的形成密切相关。这些发现为进一步探索 CePIN 的功能提供了基础性认识，并为研究大花芹菜的花瓣发育提供了宝贵的见解。

期刊介绍： Tropical Plant Biology covers the most rapidly advancing aspects of tropical plant biology including physiology, evolution, development, cellular and molecular biology, genetics, genomics, genomic ecology, and molecular breeding. It publishes articles of original research, but it also accepts review articles and publishes occasional special issues focused on a single tropical crop species or breakthrough. Information published in this journal guides effort to increase the productivity and quality of tropical plants and preserve the world’s plant diversity. The journal serves as the primary source of newly published information for researchers and professionals in all of the aforementioned areas of tropical science.
