摘要

在日本落叶松中共鉴定出12个SPL基因家族成员。这12种LkSPLs在体细胞胚胎发生过程中的表达模式表明它们参与了体细胞胚胎的发育。此外，激素响应谱表明，LkSPLs受植物激素的转录调控，包括SA（水杨酸）、ABA（脱落酸）、IAA（吲哚-3-乙酸）、GA（赤霉素）和MeJA（茉莉酸甲酯），从而介导其生物学功能。

SPL gene family in Larix kaempferi: identification, functional analysis, and roles in somatic embryogenesis and hormonal regulation

A total of 12 SPL gene family members were identified in Larix kaempferi. The expression patterns of these 12 LkSPLs during somatic embryogenesis suggest their involvement in somatic embryo development. Furthermore, the hormone-responsive profiles indicate that the LkSPLs are transcriptionally regulated by phytohormones, including SA (salicylic acid), ABA (abscisic acid), IAA (indole-3-acetic acid), GA (gibberellin), and MeJA (methyl jasmonate), thereby mediating their biological functions.

期刊介绍： Trees - Structure and Function publishes original articles on the physiology, biochemistry, functional anatomy, structure and ecology of trees and other woody plants. Also presented are articles concerned with pathology and technological problems, when they contribute to the basic understanding of structure and function of trees. In addition to original articles and short communications, the journal publishes reviews on selected topics concerning the structure and function of trees.
