Fusarium head blight (FHB) or head Scab is a very devastating fungal disease of wheat. Epidemics results with severe yield losses and overall seed quality reduction due to mycotoxins contaminated grains. Several species of Fusarium are found associated with the disease. But, incidence and severity of FHB and the composition of Fusarium species involved are reported to vary among geographical regions and years due to variations in climatic condi-tions and cropping practices. Climatic conditions, and even local variations in weather, can limit the range of species observed even if several are present, and influence their relative frequency of recovery. Our present study gives an idea about the distribution dynamics of FHB causing Fusarium spp. at three different locations in India. Most of the species can be found in much of geographical area affected but individual species dominate a specific re-gion. Analysis of the results of present study indicated that three Fusarium spp. i.e. F. graminearum, F. pallidoroseum and F. oxysporum were found as-sociated with FHB but F. graminearum was the dominant in all the location surveyed. Other two species are also associated with the disease but fre-quency was low. As these geographical locations represent different climatic conditions, the high relative distribution frequency of F. graminearum indi-cates its better adaptability to variable environmental conditions. Under-standing the pathogen distribution dynamics may also provide insights into the epidemiology and evolutionary potential of Fusarium spp. and could lead to improved management strategies under present climate change scenario.

Fusarium head blight (FHB) or head scab is emerging as a destructive disease affecting the quantity and quality of wheat worldwide. Several Fusarium spe-cies have been associated with the disease but their composition varies among geographical regions and years. Climatic factors like temperature, pH and humidity influence the growth, survival and infestation of Fusarium species. In the present study, response of thirty six isolates of three Fusarium spp. viz F. graminearum, F. oxysporum and F. pallidoroseum (F. semitectum) to different temperature and pH was assessed by analysing their in vitro growth rate (mm/day) on potato dextrose agar (PDA) medium. We found that all the isolates responded differentially but interestingly isolates of F. graminearum showed better tolerance at broader range of temperature and pH. This attributes make F. graminearum a widely distributed and potent pathogen of wheat.

Fusarium head blight (FHB), caused by Fusarium spp., has become one of the most destructive diseases in the world’s wheat growing areas , especially in the humid and semihumid regions (Paillard et al. 2004, Mesterhazy 1978, Stack & Mullen 1985; Kiecana 1987; Kiecana et al. 1988). Six winter wheat cultivars, recently released and widely grown in Trasylvania, have been evaluated for FHB resistance during 2006. The evaluation was made by means of artificial inoculations with Fusarium graminearum and assesment of symptom intensity by computing AUDPC index (Area Under Developmental Progress Curve). Based on these data, two cultivars (Dumbrava and Turda 195) were considered as resistant, two cultivars (Ardeal and Arieşan) as medium resistant and other two cultivars (Fundulea 4 and GK Öthalom) as susceptible to FHB. The reaction to FHB of the six tested cultivars, based on the postharvest indices, showed significant differences among these cultivars as far as the yield elements and the total grain yield were considered. Actually, in the resistant cultivars, both the total grain yield and some of the yield elements (spike wight, grain weght/spike and 1000 kernel weigt) were significantly less affected by FHB than in medium resistant and susceptible cultivars.

Fusarium crown rot of wheat has become more prevalent in China. To investigate the phylogenetic structure of Fusarium causing wheat crown rot in China, wheat basal stems with symptoms of the disease were collected from 2009 to 2013 in Jiangsu, Anhui, Henan, Hebei, and Shandong provinces. In total, 175 Fusarium isolates were collected and their mycotoxin chemotypes and distribution were identified. Among the 175 isolates, 123 were Fusarium asiaticum; 95 of these were the chemotype 3-acetyl-deoxynivalenol (3-AcDON) and 28 were nivalenol (NIV). Thirty-seven isolates belonged to F. graminearum, which were all 15-AcDON. Smaller numbers of isolates consisted of F. acuminatum, F. pseudograminearum, and F. avenaceum. The virulence of F. asiaticum and F. graminearum isolates on wheat crowns and heads was comparable. The virulence of isolates of the DON and NIV chemotype were statistically similar, but DON tended to be more aggressive. The DON concentrations in grains from wheat heads inoculated with isolates causing either Fusarium head blight or crown rot were similar. In the five provinces, F. asiaticum of the 3-AcDON chemotype was the predominant pathogen causing crown rot, followed by F. graminearum. Recent changes in causal Fusarium species, chemotypes, and distribution in China are discussed.

Relative Prevalence

In the main wheat production area of China (The Huang Huai Plain, HHP), both Fusarium graminearum and F. asiaticum, the causal agents of Fusarium head blight (FHB), are present. We investigated whether the relative prevalence of F. graminearum and F. asiaticum is related to cropping systems and/or climate factors. A total of 1844 Fusarium isolates were obtained from 103 fields of two cropping systems: maize-wheat and rice-wheat rotations. To maximize the differences in climatic conditions, isolates were sampled from the north and south HHP region. Based on the phylogenetic analysis of EF-1α and Tri101sequences, 1207 of the 1844 isolates belonged to F. graminearum, and the remaining 637 isolates belonged to F. asiaticum. The former was predominant in the northern region: 1022 of the 1078 Fusarium isolates in the north were F. graminearum. The latter was predominant in the southern region: 581 of the 766 Fusarium isolates belonging to F. asiaticum. Analysis based on generalised linear modelling, the relative prevalence of the two species was associated more with climatic conditions than with the cropping system. Fusarium graminearum was associated with drier conditions, cooler conditions during the winter but warmer conditions in the infection and grain-colonization period, and with the maize-wheat rotation. The opposite was true for F. asiaticum. Except 15-ADON, the trichothecene chemotype composition of F. asiaticum differed between the two cropping systems. The 3-ADON was more prevalent in the maize-wheat rotation; whereas NIV more prevalent in the rice-wheat rotation. The results also suggested that environmental conditions in the overwintering period appeared to be more important than that in the infection and grain-colonization and pre-anthesis sporulation periods in affecting the relative prevalence of F. graminearum and F. asiaticum. More research is needed to study the effect of overwintering conditions on subsequent epidemic in the following spring.

Fusarium head blight (FHB) is a destructive disease of wheat that reduces yield and grain quality. High-throughput proteomic techniques have been used to identify a wide range of candidate proteins involved in host resistance. The majority of the published works on the proteomics of the wheat response to Fusarium graminearum infection are case specific. In the current study, a high-throughput quantitative label-free strategy was employed on bulked rachides of F. graminearum-infected wheat collected from multiple genotypes. Differentially accumulated proteins among the following four pools were identified: mock-inoculated FHB-resistant accessions (RM), mock-inoculated FHB-susceptible accessions (SM), F. graminearum-inoculated FHB-resistant accessions (RFg), and F. graminearum-inoculated FHB-susceptible accessions (SFg). Four pairs of comparisons were made: RFg versus RM, SFg versus SM, RM versus SM, and RFg versus SFg. Proteins were projected onto the consensus intervals of previously reported quantitative trait loci in the FHB-resistant pool by blasting against the Chinese Spring reference sequences. In addition to proteins previously reported in the host response to Fusarium spp., new candidates have emerged in association with resistance or susceptibility, including a group 3 late embryogenesis abundant as a resistance-related protein and a purple acid phosphatase as a susceptibility protein. The protein atlas presented here provides new perspectives on the interaction between F. graminearum and wheat.

The effects of fungicides on Fusarium spp. and their associated mycotoxins in naturally infected winter wheat grain Field trials conducted at the Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry (central part of Lithuania) in 2009 were aimed to evaluate the effect of fungicides on Fusarium Head Blight (FHB) in a naturally infected field. A single application of dimoxystrobin + epoxiconazole (Swing Gold), prothioconazole (Proline), metconazole (Juventus), tebuconazole (Folicur), prothioconazole + tebuconazole (Prosaro) was applied to winter wheat cv. ‘Zentos’ at the manufacturer's recommended doses at anthesis (BBCH 65). The FHB incidence and severity were assessed at milk and hard maturity stages. The percentage of Fusarium infected grain and deoxynivalenol (DON), zearalenone (ZEN) and T-2 toxin (T-2) concentrations in harvested grain were determined. In all fungicide treated plots a significant reduction of FHB incidence and severity was determined; however the fungicides did not exert any effect on the amount of Fusarium-infected grain as compared with the untreated control. A reduction of DON, ZEN and T-2 contents in grain was determined in tebuconazole treatments. Fusarium avenaceum (Fr.) Sacc, F. culmorum (W. G. Sm.) Sacc., F. poae (Peck) Wollenw, F. sporotrichioides Sherb. and F. tricinctum (Corda) Sacc were identified in wheat grain, F. poae was prevalent.
