Abstract

Patchouli (Pogostemon cablin), is an industrially important aromatic plant that produces patchouli oil. The present experiment aimed to generate polyploid plants of patchouli with increased herb yield, oil production, and higher patchouli alcohol content. In the present study, colchicine, a chemical compound known to induce polyploidy was used at concentrations of 0.2% and 0.3% for 48 h. The diploid variety CIM-Shrestha (2n = 2X = 32) was used as the starting point. Polyploidy was successfully induced in vitro conditions and confirmed through various analyses including chromosome counting, anatomical, morphological, and gene expression studies. Treating the diploid callus with 0.2% colchicine resulted in viable and stable tetraploid seedlings. These tetraploids had a chromosomal count of 2n = 4x = 64. Tetraploids exhibited distinct morphological, anatomical, and chemical characteristics, such as thicker leaves, more oil glands, higher chloroplast numbers, larger stomata size, patchouli alcohol, and α-Guaiene. In field conditions, the induced tetraploids remained stable and the majority of tetraploid lines showed higher oil content and patchouli alcohol concentrations compared to diploid plants, although herb yield was lower in tetraploids. In the gene expression study, five (PcHMGR, PcFPPS, PcTPSCF2, PcTPSB15, and PcPTS, along with the expression of the control gene Pc18S) pathway genes related to the patchouli alcohol production pathway were studied. The Real Time-qPCR results show that there was no significant change in the expression of any of the five analyzed genes.

通过形态解剖学、细胞学、化学分型和分子方法诱导广藿香(Pogostemon cablin Benth.)
广藿香(Pogostemon cablin)是一种重要的工业芳香植物,可生产广藿香油。本实验旨在培育广藿香多倍体植株,以提高药草产量、产油量和广藿香醇含量。本研究以二倍体品种 CIM-Shrestha(2n = 2X = 32)为起点,使用浓度为 0.2% 和 0.3% 的秋水仙素(一种已知可诱导多倍体的化合物),持续 48 小时。在离体条件下成功诱导了多倍体,并通过染色体计数、解剖学、形态学和基因表达研究等各种分析进行了确认。用 0.2% 的秋水仙素处理二倍体胼胝体,可培育出成活且稳定的四倍体幼苗。这些四倍体的染色体数为 2n = 4x = 64。四倍体表现出明显的形态、解剖和化学特征,如叶片更厚、油腺更多、叶绿体数量更高、气孔更大、广藿香醇和α-愈创木酚含量更高。在田间条件下,诱导的四倍体保持稳定,与二倍体植物相比,大多数四倍体品系的含油量和广藿香醇浓度更高,但四倍体的药草产量较低。在基因表达研究中,研究了与广藿香醇生产途径相关的五个途径基因(PcHMGR、PcFPPS、PcTPSCF2、PcTPSB15 和 PcPTS,以及对照基因 Pc18S 的表达)。实时 qPCR 结果表明,所分析的五个基因的表达均无明显变化。

期刊介绍: This journal highlights the myriad breakthrough technologies and discoveries in plant biology and biotechnology. Plant Cell, Tissue and Organ Culture (PCTOC: Journal of Plant Biotechnology) details high-throughput analysis of gene function and expression, gene silencing and overexpression analyses, RNAi, siRNA, and miRNA studies, and much more. It examines the transcriptional and/or translational events involved in gene regulation as well as those molecular controls involved in morphogenesis of plant cells and tissues. The journal also covers practical and applied plant biotechnology, including regeneration, organogenesis and somatic embryogenesis, gene transfer, gene flow, secondary metabolites, metabolic engineering, and impact of transgene(s) dissemination into managed and unmanaged plant systems.
