Special Issue Information

Dear Colleagues,

Spice crops are one of the most important crops in the world and play an important role in the human table with their unique aroma and medicinal value. Since the release of the Arabidopsis genome sequence in 2000, more than 400 plant genome sequences have become available. Meanwhile, various technologies and bioinformatics tools have been developed for sequencing, assembling, annotating, and analyzing plant genomes. Now that the genomes of spice crops such as garlic, green onion, onion, and ginger have been published, this Special Issue of Agronomy will focus on the genetics, genomics, and breeding of spice crops. We welcome all original research papers and reviews on genomics, genetics, and gene function analysis of spice crops and believe that your contribution will significantly impact the future of spice crop breeding.

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. Agronomy 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.

In recent years, frequent high temperatures and heavy rainfall in summer in China have led to a large-scale reduction in Welsh onion (Allium fistulosum L.) production. This experiment used “Hanchuan” Welsh onion as test material to analyze the effect of high temperature and waterlogging on the dry matter quality, root structure, oxygen species (ROS) metabolism, and photosynthetic performance. The results showed that waterlogging or high-temperature stress could lead to a decrease in dry matter content and root activity in various parts of Welsh onion, significantly increasing the content of reactive oxygen species (ROS) in Welsh onion roots and leaves, accelerating membrane lipid peroxidation, and significantly reduce the chlorophyll content and photosynthetic performance of Welsh onion. Among them, the damage caused by waterlogging and high-temperature interaction stress to Welsh onion is the most significant. On the 8th day of treatment, the net photosynthetic rate (Pn) of high-temperature normal water supply, normal-temperature waterlogging, and high-temperature waterlogging decreased by 53.62%, 26.4%, and 87.59%, respectively, compared to the control. The results of this study provide insight into the extent of damage to Welsh onion under different moisture and temperature conditions, which will help explore scientific methods to alleviate the damage caused by high temperature and waterlogging in Welsh onion in the future.
