Special Issue Information

Dear Colleagues,

Fiber crops, as the world’s most important crops, play a significant role in the revolution of modern bio-based textiles products eventually replacing much of the petrochemical industry. Molecular genetics and functional genomics are leading the way to improving breeding efficiency by understanding the crops genome and gene regulation, and applying this information to the identification of markers, favorable genes alleles, or metabolic processes. Moreover, advances in modern biotechnology have resulted in the development of powerful techniques that have greatly promoted crop improvement with economic progress, sustainable productivity, and environmental compatibility. For example, cotton has been a leader in the use of biotechnology. The commercialization of Bt cotton and herbicide-resistant cotton in the world is just the beginning of the biotechnological revolution. More advanced biotechnologies include gene editing (for example, protein modification by coding sequence mutation or over/suppressed expression by promoter manipulation), cell engineering, and asexual breeding. The advances in new biotechnologies have made it possible to develop plants that contain genes that were not possible to be developed by sexual approaches. A crop breeding revolution will be taking place with generation of biotech products for fiber crop improvement on more complex traits, such as quality, drought, salinity, or fertilizer use.

We welcome submissions of different types of manuscripts, including original research papers, reviews, and methods, including, but not limited to: significant progress on structural and functional genomics, genetics, and the application of modern breeding biotechnologies in fiber crops. This collection of articles will provide the knowledge base and new solutions for fiber crops improvement.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agriculture is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Agave angustifolia is an important crassulacean acid metabolism plant species, with wide applications in beverage and sisal fiber production. In this study, we carried out a transcriptome analysis of A. angustifolia leaves, generating a total of 58,482,436 clean reads through Illumina paired-end sequencing. De novo transcriptome assembly generated 67,314 unigenes, with about half of them having homologs in four public databases. In the Nr database, Asparagus officinalis was shown to be most closely related to agave, and the early angiosperm Amborella trichopoda was selected as an outgroup species. We further identified five, two, seven, seven, seven, six and six CAD genes in asparagus, amborella, A. deserti, A. tequilana, A. americana, A. hybrid H11648 and A. angustifolia, respectively. The maximum likelihood phylogenetic tree revealed the species-specific expansion of CAD genes in arabidopsis, rice and agave. The expression analysis indicated the conservatively expressed CAD1/2/4/6, providing candidate targets for manipulation to improve lignin traits. The species-specific expression of CAD3/5/7 indicates the existence of different regulatory mechanisms controlling the expression of these genes in agave species. This study presents the first transcriptome dataset of A. angustifolia, facilitating future studies on lignin biosynthesis in agave. Full article
