“…Bast fibres and silks are two of the most popular sources of textile fabric in Chinese history. Ramie, commonly known as China grass, is one of the most important bast fibre crops in ancient China, and its fibres have been used as textiles for over 4700 years, according to archaeological evidence (Liao et al ., 2014). Presently, ramie is the second most important fibre crop in China, and its growth acreage and quantity of fibre production are second only to those of cotton (Liu et al ., 2014a).…”

Summary Ramie is an important fibre‐producing crop in China; however, the genetic basis of its agronomic traits remains poorly understood. We produced a comprehensive map of genomic variation in ramie based on resequencing of 301 landraces and cultivars. Genetic analysis produced 129 signals significantly associated with six fibre yield‐related traits, and several genes were identified as candidate genes for respective traits. Furthermore, we found that natural variations in the promoter region of Bnt14G019616 were associated with extremely low fibre abundance, providing the first evidence for the role of pectin methylesterase in fibre growth of plants. Additionally, nucleotide diversity analysis revealed that breeding selection has been markedly focussed on chromosome 9 in which ~ 39.6% sequence underwent selection, where one gibberellin‐signalling‐repressed DELLA gene showed distinct selection signatures in the cultivars. This study provides insights into the genetic architecture and breeding history of fibre yield traits in ramie. Moreover, the identification of fibre yield‐related genetic loci and large‐scale genomic variation represent valuable resources for genomics‐assisted breeding of this crop.

“…It has been grown for at least 6000 years in Asia. Approximately 70,000 ha are now cultivated worldwide (primarily in China), with 124,000 tonnes harvested in 2013 (http://faostat3.fao.org/) [1]. Ramie is valued primarily for its long, strong phloem (i.e., bast) fibers, which are used in textiles, most often as a blend with other types of fibers.…”

Ramie (Boehmeria nivea) is a perennial crop valued for its strong bast fibers. Unlike other major bast fiber crops, ramie fiber processing does not include retting, but does require degumming, suggesting distinctive features in pectin and the development and composition of fibers. A comprehensive transcriptome assembly of ramie has not been made available, to date. We obtained the sequence of RNA transcripts (RNA Seq) from the apical region of developing ramie stems and combined these with reads from public databases for a total of 157,621,051 paired-end reads (30.3 billion base pairs Gbp) used as input for de novo assembly, resulting in 70,721 scaffolds (≥200 base pairs (bp); N 50 = 1798 bp). As evidence of the quality of the assembly, 36,535 scaffolds aligned to at least one Arabidopsis protein (BLASTP e-value ≤ 10 −10 ). The resource described here for B. nivea will facilitate an improved understanding of bast fibers, cell wall, and middle lamella development in this and other comparative species.

“…Others have reported that ramie originated from the middle and lower reaches of the Yellow River based on the distribution of wild resources and historical data [7]. However, the exact geographic region of domestication has not been identified yet [8]. Today, the loss of ramie from its most important natural habitat in China and the need to effectively utilize its genetic resources in crop improvement, highlight the study of the genetic diversity of this species as fundamental.…”

Ramie (Boehmeria nivea L. Gaud) is one of the most important natural fibre crops. For enhanced crop development, it is necessary to understand its population structure and genetic relationships. In this study, we assessed the genetic diversity and population structure of 134 ramie accessions (with three plants per accession) from 12 regions by using 36 simple sequence repeat markers. The 36 microsatellite primers revealed 149 alleles in 134 ramie populations, with an average of 4.14 alleles per locus. The structure analysis divided the 134 ramie accessions into three groups (I, II and III), and into further six subgroups (a, b, c, d, e and f). In Subgroup b, 13 accessions were from Guizhou Province, 9 accessions were from Sichuan Province and the remaining 20 accessions were from Chongqing (4), Hunan (8), Guangxi (4), Jiangxi (2), Yunan (1) and Taiwan (1). In Subgroup d, 22 accessions were from Guizhou Province and the remaining 17 accessions were from Chongqing (6), Sichuan (5) and Yunnan (6). It can be inferred that the genetic background of these ramie accessions did not always correlate with their geographical regions. Similar results were found in Subgroups a and f. The pair-wise genetic similarity coefficients between the 134 accessions ranged from 0.390 to 0.939, which suggested that there was abundant genetic diversity in the ramie accessions. These markers have provided important information about the genetic structure of ramie, which can contribute to future breeding and improvement programmes for these resources.
