TLDR
More than 120 different formae speciales have been identified based on specificity to host species belonging to a wide range of plant families as mentioned in this paper, which can cause severe losses in many vegetables and flowers, field crops, such as cotton, and plantation crops such as banana, date palm and oil palm.Abstract:
Taxonomy: Kingdom Fungi; Phylum Ascomycota; Class Sordariomycetes; Order Hypocreales; Family Nectriaceae; genus Fusarium. Host range: Very broad at the species level. More than 120 different formae speciales have been identified based on specificity to host species belonging to a wide range of plant families. Disease symptoms: Initial symptoms of vascular wilt include vein clearing and leaf epinasty, followed by stunting, yellowing of the lower leaves, progressive wilting, defoliation and, finally, death of the plant. On fungal colonization, the vascular tissue turns brown, which is clearly visible in cross-sections of the stem. Some formae speciales are not primarily vascular pathogens, but cause foot and root rot or bulb rot. Economic importance: Can cause severe losses in many vegetables and flowers, field crops, such as cotton, and plantation crops, such as banana, date palm and oil palm. Control: Use of resistant varieties is the only practical measure for controlling the disease in the field. In glasshouses, soil sterilization can be performed.

Identification and characterization of pathogens causing saffron corm rot in China
TL;DR: In this article , the authors used a combination of amplicon sequencing and traditional isolation methods to identify the causal agents, main infection source, of saffron corm rot, and found that the diversity of microbial communities in diseased saffral corms and soil decreased significantly compared with healthy corm and soil, indicating that fungi from several genus such as Fusarium spp. and Botrytis spp., have been previously reported to be the pathogens.

TL;DR: In this paper , the authors inspected global transcription factor profiles (TFomes) and their potential roles in coordinating CCs and ACs functions to accomplish host-specific pathogenicity, and found a clear positive correlation between the sizes of TFome and proteome of an organism.

TL;DR: In this paper , the authors conducted a time-lapse analysis of one susceptible and one resistant cultivar over a two-week period following infection and found that the susceptible cultivar showed a strong onset of symptoms from 6 to 8 days after inoculation, which was associated with changes in metabolites in both cultivars.

Current Status of the Gene-For-Gene Concept
TL;DR: The gene-for-gene hypothesis suggests that for each gene that conditions reaction in the host there is a correspond ing gene in the parasite that conditions pathogenicity.
