“…The class III homeodomain-leucine zipper (HD-ZIP III) family of transcription factors (TFs) is unique to the plant kingdom; it plays important roles in regulating embryo patterning, meristem formation, organ polarity, vascular development, and meristem function (Mcconnell et al 2001;Du and Wang 2015;Bustamante et al 2016;Shi et al 2016). The HD-ZIP III family of Arabidopsis consists of five members, including REVOLUTA (REV), PHABULOSA (PHB), PHAVOLUTA (PHV), CORONA (CNA) and ATHB8 (Baima et al 1995;Green et al 2005).…”

Background: Manual topping is a routine agronomic practice for balancing the vegetative and reproductive growth of cotton (Gossypium hirsutum) in China, but its cost-effectiveness has decreased over time. Therefore, there is an urgent need to replace manual topping with new approaches, such as biological topping. In this study, we examined the function of GhREV transcription factors (a class III homeodomain-leucine zipper family, HD-ZIP III) in regulating the development of shoot apical meristem (SAM) in cotton with the purpose of providing candidate genes for biological topping of cotton in the future. Results: We cloned four orthologous genes of AtREV in cotton, namely GhREV1, GhREV2, GhREV3, and GhREV4. All the GhREVs expressed in roots, stem, leaves, and SAM. Compared with GhREV1 and GhREV3, the expression level of GhREV2 and GhREV4 was higher in the SAM. However, only GhREV2 had transcriptional activity. GhREV2 is localized in the nucleus; and silencing it via virus-induced gene silencing (VIGS) produced an abnormal SAM. Two key genes, GhWUSA10 and GhSTM, which involved in regulating the development of plant SAM, showed about 50% reduction in their transcripts in VIGS-GhREV2 plants.Conclusion: GhREV2 positively regulates the development of cotton SAM by regulating GhWUSA10 and GhSTM potentially.

“…Coincidently, CesA 8 from Arabidopsis was found to play a role in secondary cell wall synthesis in flax [1]. In addition to cellulose synthases, FLAs and BGALs have also been reported to be involved in the formation of cellulose rich gelatinous fibers [1,[16][17][18]. Among the DEGs in the cluster 2, FLA 11/12 and BGAL 3/9 are up-regulated in ER and FER (Additional file 1: Table S2).…”

“…Gene transcriptional regulatory networks and signaling cascade integrating signals for secondary cell wall biosynthesis have been gradually uncovered in recent years. NAC (NO APICAL MERI-STEM, ATAF1, ATAF2, and CUP-SHAPED COTYLE-DON 2) and MYB (myeloblastosis) transcription factors are thought to be the master switches that regulate the downstream transcription factors involved in the weaving of the network [14][15][16][17][18]. In one of the proposed models, at least three layers of regulators, which include NAC domain master regulators in the tier 3, two MYB domain regulators in the tier 2 and many other regulators in the tier 1, are likely to be directly involved in regulating secondary cell wall biosynthesis [18].…”

Background: Boehmeria nivea L. Gaud (Ramie) produces one of the longest natural fibers in nature. The bark of ramie mainly comprises of the phloem tissue of stem and is the raw material for fiber. Therefore, identifying the molecular regulation of phloem development is important for understanding of bast fiber biosynthesis and improvement of fiber quality in ramie. Results: In this study, we collected top bud (TB), bark from internode elongating region (ER) and bark from internode fully elongated region (FER) from the ramie variety Zhongzhu No. 1. Histological study indicated that these samples contain phloem tissues at different developmental and maturation stages, with a higher degree of maturation of phloem tissue in FER. RNA sequencing (RNA-seq) was performed and de novo transcriptome was assembled. Unigenes and differentially expressed genes (DEGs) in these three samples were identified. The analysis of DEGs by using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) revealed clear differences in gene expression between ER and FER. Some unigenes involved in secondary cell wall biosynthesis were up-regulated in both ER and FER, while unigenes for some cell wall components or cell wall modifications showed differential expression between ER and FER. In addition, the ethylene respond factors (ERFs) in the ethylene signaling pathway were up-regulated in FER, and ent-kaurenoic acid oxidase (KAO) and GA 20-oxidase (GA20ox) for gibberellins biosynthesis were up-regulated while GA 2-oxidase (GA2ox) for gibberellin inactivation was down-regulated in FER.Conclusions: Both morphological study and gene expression analysis supported a burst of phloem and vascular developmental processes during the fiber maturation in the ramie stem, and ethylene and gibberellin are likely to be involved in this process. Our findings provide novel insights into the phloem development and fiber maturation in ramie, which could be useful for fiber improvement in ramie and other fiber crops.
