Special Issue Information

Dear Colleagues,

Plant infectious-disease caused by pathogenic microorgisms such as fungi, oomycetes , bacteria,virus and nematodes can lead to annually economic loses of $220 billion. Among them, fungi is the most important type of plant pathogen, seriously threatening the producation of plants, The Top 10 plant pathgenic fungi are Magnaporthe oryzae, Botrytis cinerea, Puccinia spp., Fusarium graminearum, Fusarium oxysporum, Blumeria graminis, Mycosphaerella graminicola, Colletotrichum spp., and Ustilago maydis, and Melampsora lini. Significant scientific advances are achieved on different specific areas relevant to disease management in last decade, high-throughput sequencing, rapid detection and diagnosis, plant immune and genetic diversity, microbiome, advanced omics, novel bio-protectants and new green targeted fungicide, for example.

With this Special Issue of Plants, we welcome study of all aspects focusing on the management strategy towards plant fungal disease, espeaclially for the top 10 and related fungi. Integrative research of management program to provide broader impact and success, as well as reviews that offer original perspectives, are all welcome.

Rice spikelet rot disease (RSRD) affects the production and market price of rice, and can be harmful to humans and livestock. In this study, 51 strains of Fusarium spp. were isolated from rice spikelets in the Lin’an, Yuhang, and Fuyang regions. The isolates comprised four composite species: Fusarium incarnatum-equiseti species complex (FIESC), Fusarium asiaticum species complex (FSAMSC), Fusarium fujikuroi species complex (FFSC), Fusarium commune species complex (FNSC), and five species of Fusarium spp. (F. luffae, F. sulawesiense, F. asiaticum, F. fujikuroi, and F. commune). The separation rate of F. sulawesiense was the highest (41.2%), followed by F. asiaticum at 37.3%. The results of this study, compared with those of other studies, found that the newly discovered species of Fusarium spp. associated with RSRD were FSAMSC (F. asiaticum) and FNSC (F. commune). Temperature is one of the important factors causing RSRD; the optimal growth temperature for F. sulawesiense and F. commune was 30 °C, and the optimal growth temperature for other species was 25 °C. A high temperature of 35 °C did not inhibit the growth of Fusarium, as F. commune and F. fujikuroi could grow at this temperature. At 20–30 °C, the growth rate of F. asiaticum was higher than those of other strains. To determine whether the occurrence of RSRD is related to the correlation between Fusarium and other fungi in rice spikelets under different health conditions, the genetic diversity of fungi in rice spikelets was analyzed by amplicon Internal Transcribed Spacer (ITS) sequencing, and the correlations between strains of Fusarium spp. were measured. The results showed that the fungal diversity of diseased rice spikelets (RD) was higher than that of relatively healthy rice spikelets (RH). Curvularia spp., which was affected by the condition of the spikelets, was negatively correlated with Fusarium spp. in RH and positively correlated with Fusarium spp. in RD. Therefore, Fusarium spp. and Curvularia spp. can jointly cause the occurrence of RSRD. The results of the study are significant for understanding the occurrence of RSRD and formulating prevention and control measures. Full article

Saffron corm rot (SCR), the most serious disease affecting saffron, has been confirmed to be caused by Fusarium oxysporum in previous studies. Compared to other fungal species, F. oxysporum exhibits host specialization, a special phenomenon associated with the secreted in xylem (SIX) genes. This study examined the pathogenicity specialization of F. oxysporum isolated from saffron corms with SCR disease. The results showed that this F. oxysporum strain was strongly pathogenic to saffron corms, causing SCR; weakly pathogenic to the corms of freesia, which is in the Iridaceae family along with saffron; and not pathogenic to watermelon, melon, and tomato. Other formae speciales of F. oxysporum were not pathogenic to saffron corms. This suggests that F. oxysporum saffron strains exhibit obvious pathogenicity specialization for Iridaceae spp. Subsequently, the F. oxysporum saffron strain (XHH35) genome was sequenced, and a comparative genomics study of XHH35 and three other formae speciales was conducted using OrthoVenn3. XHH35 contained 90 specific genes absent in the other three formae speciales. These genes are involved in certain key biological processes and molecular functions. Based on BLAST homology searching, the F. oxysporum saffron strain (XHH35) genome was predicted to contain seven SIX genes (SIX 4, SIX 6, SIX 7, SIX 10, SIX 11, SIX 12, and SIX 14) highly homologous to F. oxysporum f. sp. lycopersici, which was verified using polymerase chain reaction (PCR) amplification. The corresponding individual phylogenetic tree indicated that the F. oxysporum saffron strain (XHH35) showed a separate branch with different formae speciales. This study is the first-ever report of F. oxysporum f. sp. crocus, a new forma specialis. Based on the specificity of its SIX genes, the SIX 10 gene was selected to further establish a rapid identification technique for F. oxysporum f. sp. crocus, which will be useful in future research.
