Special Issue Information

Dear Colleagues,

Flower longevity is an important trait determining the quality of commercial flowers. The vase life of cut flowers is often correlated with the longevity of the petals. Therefore, many papers on petal senescence have been reported. Senescent symptoms of petals are divided into petal wilting and abscission. In the petals of many plants, including carnations, petal senescence is regulated by endogenous ethylene. In contrast, the petal senescence of other plants, including gladioli, is independent from ethylene. Irrespective of ethylene dependence, programmed cell death (PCD) is involved in petal senescence. In ethylene-dependent types of flowers, there have been many studies on ethylene biosynthesis and ethylene signaling networks. It is possible to extend the longevity of petals by using inhibitors of ethylene action or biosynthesis. In ethylene-independent flowers, petal longevity can be regulated by the silencing of genes involved in PCD. In addition, it is known that plant hormones such as cytokinin delay the senescence of petals. In this Special Issue, we welcome the submission of articles containing novel findings that contribute to our understanding of the molecular mechanism of petal senescence exhibiting ethylene-dependent or ethylene-independent characteristics. We also welcome articles on new technologies for controlling petal senescence.

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. Plants is an international peer-reviewed open access semimonthly 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 2700 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.

Botrytis cinerea (B. cinerea) causes gray mold disease (GMD), which results in physiological disorders in plants that decrease the longevity and economic value of horticultural crops. To prevent the spread of GMD during distribution, a rapid, early detection technique is necessary. Thermal imaging has been used for GMD detection in various plants, including potted roses; however, its application to cut roses, which have a high global demand, has not been established. In this study, we investigated the utility of thermal imaging for the early detection of B. cinerea infection in cut roses by monitoring changes in petal temperature after fungal inoculation. We examined the effects of GMD on the postharvest quality and petal temperature of cut roses treated with different concentrations of fungal conidial suspensions and chemicals. B. cinerea infection decreased the flower opening, disrupted the water balance, and decreased the vase life of cut roses. Additionally, the average temperature of rose petals was higher for infected flowers than for non-inoculated flowers. One day before the appearance of necrotic symptoms (day 1 of the vase period), the petal temperature in infected flowers was significantly higher, by 1.1 °C, than that of non-inoculated flowers. The GMD-induced increase in petal temperature was associated with the mRNA levels of genes related to ethylene, reactive oxygen species, and water transport. Furthermore, the increase in temperature caused by GMD was strongly correlated with symptom severity and fungal biomass. A multiple regression analysis revealed that the disease incidence in the petals was positively related to the petal temperature one day before the appearance of necrotic symptoms. These results show that thermography is an effective technique for evaluating changes in petal temperature and a possible method for early GMD detection in the cut flower industry. Full article

Gaseous factors affect post-harvest physiological processes in horticultural crops, including ornamental flowers. However, the molecular responses of cut flowers to the low-oxygen conditions associated with modified atmosphere packaging (MAP) have not yet been elucidated. Here, we show that storage of cut carnation flowers in a sealed polypropylene bag decreased the oxygen concentration in the bag to 3–5% and slowed flower opening. The vase life of carnation flowers after storage for seven days under MAP conditions was comparable to that without storage and was improved by the application of a commercial-quality preservative. The adenylate energy charge (AEC) was maintained at high levels in petals from florets stored under MAP conditions. This was accompanied by the upregulation of four hypoxia-related genes, among which the HYPOXIA-RESPONSIVE ETHYLENE RESPONSE FACTOR and PHYTOGLOBIN genes (DcERF19 and DcPGB1) were newly identified. These results suggest that hypoxia-responsive genes contribute to the maintenance of the energy status in carnation flowers stored under MAP conditions, making this gas-controlling technique potentially effective for maintaining cut flower quality without cooling.
