“…Although the mRNA levels of the putative GA metabolism-related genes EgGA20ox and EgGA2ox were affected by light quality at some stages, they did not appear to correspond to those of EgFTL and EgSOC1L. As Nakano et al 2011 have suggested that the GA pathway is possibly related to the regulation of flowering by vernalization and photoperiod, expression of GA metabolism-related genes was analyzed in this study and the previous study using the EgFTL overexpressor Li et al, 2015 . However, the coordination of expression of GA metabolism-related genes and EgFTL was not observed in either study.…”

The effects of overnight radiation with monochromatic light on flower budding using far-red-and blue light-emitting diodes FR and B, respectively were investigated in Eustoma grandiflorum under controlled temperature and 8-h sunlight. Flower budding was promoted by FR and B, while it was not observed under short-day conditions with an 8-h photoperiod during the treatment period. The flower budding with FR was earlier than with B. Expression analysis of flowering-related genes and potential light quality-responsive genes was performed to find genes involved in light quality-dependent regulation of flowering. The levels of EgFTL and EgSOC1L mRNA increased preceding flower budding with FR and B, suggesting that both genes could be involved in the effects on flowering brought about by far-red and blue lights. Later and lower expression of these genes induced by B compared to FR could be associated with the weak promotion of flowering by blue light in E. grandiflorum. In potential light quality-responsive genes, the level of EgBTB-POZ1 mRNA peaked with EgFTL with FR. Collectively, EgFTL and EgSOC1 likely promote flowering with FR and B, and EgBTB-POZ1 might be possibly involved in the promotion of flowering with FR.

“…Studies had been conducted to identify Lisianthus MADS family genes (Ishimori and Kawabata, 2014) and study their functions (Li et al, 2015). However, without the support of high-throughput sequencing results such as transcriptomes or genomes, it is often more difficult to conduct gene function studies or gene family identification (Nakano et al, 2011).…”

Lisianthus (Eustoma grandiflorum) is an important ornamental plant native to North America. So far, the number of basic molecular research reports on Lisianthus is relatively small, especially the research related to the molecular mechanism of response to drought stress. In this experiment, transcriptome second-generation sequencing technology was used to study Lisianthus seedlings under drought stress. The results showed that the transcriptome sequencing data had good quality control results. In order to obtain genetic information on this basis, the sequences were spliced using software such as Trinity and Corset, a total of 102,014 non-redundant genes were obtained, including 2,929 coding genes which were found to belong to 79 transcription factor families after analyzing. Annotating all genes, Zhongguo coffee was found to be the species with the highest comparison similarity. Finally, simple sequence repeat (SSR) analysis was performed on the gene sequences, and all SSR information contained in non-redundant genes and transcription factor coding genes had been obtained. The results of this study can provide candidate molecular resources for subsequent studies on Lisianthus 's response to drought stress in the future.

“…In contrast to the data on the analysis of flowering of Eustoma in cultivation, little information is available on differences in flowering time among accessions and genetic markers that can help distinguish between such differences. The gene EgFT, the FT homolog of E. grandiflorum, acts similarly to Arabidopsis FT in regulating the flowering transition by activating floral meristem identity genes (Li et al 2015, Nakano et al 2011. However, to clarify the mechanism for regulation of flowering time in Eustoma, further genetic analysis and cultivation under strictly controlled environmental conditions are needed.…”

Development of an SSR marker-based genetic linkage map and identification of a QTL associated with flowering time in Eustoma

et al. 2021

Lisianthus (Eustoma grandiflorum) is an important floricultural crop cultivated worldwide. Despite its commercial importance, few DNA markers are available for molecular genetic research. In this study, we constructed a genetic linkage map and to detect quantitative trait loci (QTLs) for important agronomic traits of lisianthus. To develop simple sequence repeat (SSR) markers, we used 454-pyrosequencing technology to obtain genomic shotgun sequences and subsequently identified 8263 putative SSRs. A total of 3990 primer pairs were designed in silico and 1189 unique primer pairs were extracted through a BLAST search. Amplification was successful for more than 1000 primer pairs, and ultimately 278 SSR markers exhibited polymorphism between the two lisianthus accessions evaluated. Based on these markers, a genetic linkage map was constructed using a breeding population derived from crosses between the two accessions, for which flowering time differed (>140 days when grown under 20°C). We detected one QTL associated with flowering time (phenotypic variance, 27%; LOD value, 3.7). The SSR marker located at this QTL may account for variation in flowering time among accessions (i.e., three accessions whose nodes of the first flower were over 30 had late-flowering alleles of this QTL).
