“…tumdia is a popular vegetable in China, and becoming geographical indication products of Chongqing city. In recent years, ARF genes have gained widespread attention due to the large number of family members and their response to most of life processes in plants, and ARFs were genome-wide identified in Arabidopsis, rice, maize and wheat successively [6,7,8,9]. In this study, we characterized 65 B.juncea ARF genes by genome-wide analysis (S1 Table), which is a higher number than reported in other species.…”

“…Analysis of BjARF gene expression showed that these genes could be divided into four groups, and partial BjARF members were significantly expressed in plant tissues or different varieties. Many ARFs (AtARF2, AtARF7, AtARF19, OsARF1, OsARF5, OsARF19, OsARF24, SlARF2, and SlARF19) were found to be involved in regulating the development of plant roots, stems, leaves and flowers [9,20,31,51,52]. In this study, 12 candidate genes were subjected to expression pattern analysis.…”

“…To date, numerous studies have characterized the ARF gene family based on genomewide identification in many plant species, such as Arabidopsis [6], rice [7], maize [8], wheat [9], rapeseed [10], apple [11], barely [12], Vitis vinifera [13], tomato [14], Populus trichocarpa [15], Brassica rapa [16], and Brassica napus [17]. In Arabidopsis, 22 ARF genes (except one pseudogene) have been identified, which were categorized into three clades based on their amino acid sequence.…”

Auxin signalling is vital for plant growth and development, from embryogenesis to senescence. Recent studies have shown that auxin regulates biological processes by mediating gene expression through a family of functionally original DNA-binding auxin response factors, which exist in a large multi-gene family in plants. However, to date, no information has been available about characteristics of the ARF gene family in Brassica juncea var. tumida. In this study, 65 B. juncea genes that encode ARF proteins were identified in the B. juncea whole-genome, classified into three phylogenetical groups and found to be widely and randomly distributed in the A-and B-genome. Highly conserved proteins were also found within each ortholog based on gene structure and conserved motifs, as well as clustering level. Furthermore, promoter cis-element analysis of BjARFs demonstrated that these genes affect the levels of plant hormones, such as auxin, salicylic, gibberellin acid, MeJA, abscisic acid, and ethylene. Expression analysis showed that differentially expressed BjARF genes were detected during the seedling stage, tumor stem development and the flowering period of B. juncea. Interestingly, we found that BjARF2b_A, BjARF3b_A, BjARF6b_A, and BjAR-F17a_B were significantly expressed in tumor stem, and an exogenous auxin assay indicated that these genes were sensitive to auxin and IAA signaling. Moreover, eight of the nine BjARF10/16/17 genes and all of the BjARF6/8 genes were involved in post-transcriptional regulation, targeted by Bj-miR160 and Bj-miR167c, respectively. This analysis provides deeper insight of diversification for ARFs and will facilitate further dissection of ARF gene function in B. juncea.

Plant polyploids tend to have large leaves, but their formation mechanism has not yet been well explained. Therefore, daily transcriptomic differences between triploids and diploids from a synthetic Populus sect. Tacamahaca three times a day (i.e., 04:00, 09:00, and 21:00) were investigated using high-throughput RNA-seq analysis. In this study, we identified several transcription factors associated with giant leaves. The combined effects included the high expression of several transcription factors (WRKY, MYB, etc.) and hormone-related genes (e.g., activates auxin, cytokine, and brassinosteroid synthesis-related genes) that accelerate the synthesis and accumulation of endogenous hormones. High levels of growth hormones were maintained by reducing the genes’ expression of hormone metabolism and degradation. The coordination of hormones accumulated sufficient materials and energy for leaf growth and development. Thereby, cell division and growth were accelerated which enhanced the photosynthesis of leaves, and the increased accumulation of photosynthetic products led to giant triploid leaves. This study lays the foundation for revealing the molecular mechanisms in the formation of giant leaves in polyploids.

“…It is a phenyl-urea compound that has been substantiated to have the cytokinin potency across plant species [24][25][26][27]. Growth regulators' signal conversions into metabolic activities and developmental morphologies in cells or organisms have been established in biology [28][29][30][31][32][33]. The concept is broadly utilized for downstream applications particularly in cell, tissue, and organ cultures as well as plant transformation across plant species [24,[34][35][36][37].…”

Background: Daylilies are a lucrative crop used for its floral beauty, medicinal proprieties, landscaping, fire prevention, nutritional value, and research. Despite the importance, daylilies remain extremely challenging for multiplying in vitro. The response difficulty is exacerbated because a few good protocols for daylilies micropropagation are generally difficult to reproduce across genotypes. An efficient strategy, currently applied at Langston University, is to systematically explore individual tissues or organs for their potential to micropropagation. This article is a partial report of the investigation carried out under room environmental conditions and focuses on developing an efficient daylilies in vitro propagation protocol that uses the stem tissue as the principal explant. Results: In less than three months, using thidiazuron, the use of the stem tissue as the in vitro experimental explant was successful in inducing multiple shoots several folds greater than current daylilies shoot organogenesis protocols. The study showed that tissue culture can be conducted successfully under unrestricted room environmental conditions as well as under the controlled environment of a growth chamber. It also showed that splitting lengthwise stem explants formed multiple shoots several folds greater than cross-sectioned and inverted explants. Shoot conversion rate was mostly independent of the number of shoots formed per explants. The overall response was explant and genotype-dependent. Efficient responses were observed in all thidiazuron treatments. Conclusion: An efficient protocol, which can be applied for mass multiple shoots formation using the daylilies stem tissue as the main explant, was successfully developed. This could lead to a broad and rapid propagation of the crop under an array of environmental conditions to meet the market demand and hasten exogenous gene transfer and breeding selection processes.
