“…These signalling molecules are important to plant defence as well [ 15 ]. However, photosynthetic activity is deeply affected under biotic stressors such as F. verticillioides on maize [ 16 ]. In the case of Fusarium head blight, it causes a significant reduction in the net photosynthesis rate of the flag leaf of wheat plants [ 17 ].…”

Coating seeds with bio-control agents is a potentially effective approach to reduce the usage of pesticides and fertilizers applied and protect the natural environment. This study evaluated the effect of seed coating with Meyerozyma guilliermondii, strain INAT (MT731365), on seed germination, plant growth and photosynthesis, and plant resistance against Fusarium culmorum, in durum wheat under controlled conditions. Compared to control plants, seed coating with M. guilliermondii promoted the wheat growth (shoot and roots length and biomass), and photosynthesis and transpiration traits (chlorophyll, ɸPSII, rates of photosynthesis and transpiration, etc.) together with higher nitrogen balance index (NBI) and lower flavonols and anthocyanins. At 21 days post infection with Fusarium, M. guilliermondii was found to reduce the disease incidence and the severity, with reduction rates reaching up to 31.2% and 30.4%, respectively, as well as to alleviate the disease damaging impact on photosynthesis and plant growth. This was associated with lower ABA, flavonols and anthocyanins, compared to infected control. A pivotal function of M. guilliermondii as an antagonist of F. culmorum and a growth promoter is discussed.

“…The fluorescence transients were modified in the plants infected with S. sclerotiorum, which indicates that this pathogen affects the photosynthetic capacity of the soybean plant. Baghbani et al [52] demonstrated a similar outcome from the presence of the phytopathogen Fusarium sp., which affects the OJIP transients of maize plants. Photosynthesis declines naturally following infection by fungi, generally as a result of the reduction in active leaf area and the loss of chlorophyll [53,54].…”

Sclerotinia sclerotiorum is a necrotrophic parasitic fungus that causes Sclerotinia stem rot (SSR), which is currently one of the most difficult agronomic crop diseases to control. A number of plants of the Brazilian Cerrado biome have been shown to be important sources of symbiotic microorganisms with biotechnological potential, so we decided to test the potential of bacteria isolated from the dwarf jelly palm, Butia archeri (Arecaceae) for the control of the pathogenic effects provoked by S. sclerotiorum. For this, we bioprimed seeds and evaluated the effects of this biopriming on the OJIP transient patterns prior to and following infection by the phytopathogen. Plants treated with the BA48R strain of Enterobacter sp., and in particular, those treated with the BA88R strain of Bacillus cereus presented the best results in terms of the loss/gain of the physiological and symptomatological variables evaluated. The plants bioprimed with BA88R presented high post-infection levels of total chlorophyll (33.35 FCIs) and chlorophyll a (26.39 FCIs), maintained a high Nitrogen Balance Index (NBI = 18.87), and synthesized low concentrations of flavonoids (1.39). These plants also maintained high levels of PIABS (1.111) and PITOTAL (1.300) following infection, and low levels of Di0/RC (0.602), which indicates that, in the presence S. sclerotiorum, the efficiency of the photosynthesis in the plants treated with these bacteria was less affected in the reaction centers, as confirmed by the negative amplitude recorded in the L band. The present study reconfirms the importance of the use of chlorophyll fluorescence for the diagnosis of disease and conditions of stress in crop plants, in addition to demonstrating the effectivenesss of the BA48R bacterial strain and, in particular, the BA88R strain on systemic resistance induction and suppression of S. sclerotiorum in Glycine max plants, with enormous potential for the development of more sustainable agricultural processes.

Sensitivity Assessment of Varieties, Effectiveness of Weed Control by Selected Herbicides, and Infection of the Fusarium in Maize (Zea mays L.) Cultivation

et al. 2020

The amount of maize yield depends on many factors. Among them, plant health plays a significant role. Herbicide selectivity (of mesotrione, 2,4-D, and bromoxynil) for different maize varieties was assessed in greenhouse experiments. The effectiveness of herbicides (MCPA, 2,4-D + dicamba) and spraying mixture of the herbicide MCPA with mepiquat chloride was tested on Chenopodium album L. and self-seeding winter oilseed rape (Brassica napus L.). The genetic distance between selected maize varieties and species composition of pathogens of the genus Fusarium isolated from the seeds of the discussed crop were examined. Research results indicated that individual herbicides differed in the selectivity in relation to maize, which depended on the crop variety. The selected herbicides showed high efficacy against the plants used in the experiment. The addition of mepiquat chloride to the composition of the spraying liquid did not affect the level of weed control. No relationship was found between the genetic distance of maize varieties and their sensitivity to selected herbicides. The presence of Fusarium subglutinans, Fusarium proliferatum, and Fusarium verticillioides was found in the samples of maize varieties.
