Abstract
Faba bean (Vicia faba L.) is one of the most widely grown cool season legume crops in the world. Winter faba bean normally has a vernalization requirement, which promotes an earlier flowering and pod setting than unvernalized plants. However, the molecular mechanisms of vernalization in faba bean are largely unknown. Discovering vernalization-related candidate genes is of great importance for faba bean breeding. In this study, the whole transcriptome of faba bean buds was profiled by using next-generation sequencing (NGS) and single-molecule, real-time (SMRT) full-length transcriptome sequencing technology. A total of 29,203 high-quality non-redundant transcripts, 21,098 complete coding sequences (CDS), 1,045 long non-coding RNAs (lncRNAs), and 12,939 simple sequence repeats (SSRs) were identified. Furthermore, 4,044 differentially expressed genes (DEGs) were identified through pairwise comparisons. By Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, these differentially expressed transcripts were found to be enriched in binding and transcription factor activity, electron carrier activity, rhythmic process, and receptor activity. Finally, 50 putative vernalization-related genes that played important roles in the vernalization of faba bean were identified; we also found that the levels of vernalization-responsive transcripts showed significantly higher expression levels in cold-treated buds. The expression of VfSOC1, one of the candidate genes, was sensitive to vernalization. Ectopic expression of VfSOC1 in Arabidopsis brought earlier flowering. In conclusion, the abundant vernalization-related transcripts identified in this study will provide a basis for future researches on the vernalization and faba bean breeding and established a reference full-length transcriptome for future studies on faba bean.

[PMID: 31781953 DOI: 10.1007/s00425-019-03308-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/18/2019] [Accepted: 11/02/2019] [Indexed: 05/20/2023]
Abstract
This study unravels the transcriptional response of a highly productive faba bean cultivar under vernalization treatment. Faba bean (Vicia faba L.) is a member of the Leguminosae family and an important food crop worldwide providing valuable nutrients for humans. However, genome-wide studies and comprehensive sequencing resources of faba bean remain limited. Vernalization is crucial for enhanced yields in a number of winter-sown crops. However, the effects of vernalization on faba bean remain unknown. In this study, we generated a high-quality transcriptome assembly and functional annotation source for vernalized faba bean (Vicia faba L.) cv. Tongxian-2, a domesticated cultivar from southern China. A total of 369.9 million clean Illumina paired-end RNA-Seq reads were generated, and the transcriptome was assembled into 68,683 unigene sequences, with an average length of 1018 bp and an N50 of 1652 bp. Comprehensive functional annotation provided putative functional descriptions for more than 70% of the faba bean transcripts. We annotated a total of 1560 faba bean transcripts encoding transcription factors (TFs) belonging to 55 distinct TF families. The bHLH (168 transcripts), ERF (123 transcripts) and WRKY (105 transcripts) contained the largest number of TFs in response to vernalization. Genome-wide transcript changes comparing vernalized and unvernalized seedlings were investigated using bioinformatics approaches, which revealed a strong repression of photosynthesis and carbon metabolism, while genes participating in 'response to stress' were significantly induced. We also specifically identified vernalization-induced twenty-two 'pollen-pistil interaction' genes. A detailed functional annotation and expression profile analyses unveiled a number of protein kinases, which were specifically induced in vernalized seedlings. We also identified a total of 6852 simple sequence repeats (SSRs) in 6552 transcripts, representing a valuable genomic molecular marker resource for faba bean. In summary, this study provides new insights into the vernalization process in this economically valuable crop. The transcriptome data obtained provides us with a valuable candidate gene resource for future functional and molecular breeding studies. These data will contribute to the genome annotation for ensuing genome projects.

Faba Bean Cultivation - Revealing Novel Managing Practices for More Sustainable and Competitive European Cropping Systems. FRONTIERS IN PLANT SCIENCE 2018; 9:1115. [PMID: 30116251 PMCID: PMC6083270 DOI: 10.3389/fpls.2018.01115] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/19/2018] [Accepted: 07/11/2018] [Indexed: 05/14/2023]
Abstract
Faba beans are highly nutritious because of their high protein content: they are a good source of mineral nutrients, vitamins, and numerous bioactive compounds. Equally important is the contribution of faba bean in maintaining the sustainability of agricultural systems, as it is highly efficient in the symbiotic fixation of atmospheric nitrogen. This article provides an overview of factors influencing faba bean yield and quality, and addresses the main biotic and abiotic constraints. It also reviews the factors relating to the availability of genetic material and the agronomic features of faba bean production that contribute to high yield and the improvement of European cropping systems. Emphasis is to the importance of using new high-yielding cultivars that are characterized by a high protein content, low antinutritional compound content, and resistance to biotic and abiotic stresses. New cultivars should combine several of these characteristics if an increased and more stable production of faba bean in specific agroecological zones is to be achieved. Considering that climate change is also gradually affecting many European regions, it is imperative to breed elite cultivars that feature a higher abiotic-biotic stress resistance and nutritional value than currently used cultivars. Improved agronomical practices for faba bean crops, such as crop establishment and plant density, fertilization and irrigation regime, weed, pest and disease management, harvesting time, and harvesting practices are also addressed, since they play a crucial role in both the production and quality of faba bean.
