“…Some Penicillium spp. can release fixed phosphorus in the soil and make it available to plants ( Morales et al, 2007 ; Pandey et al, 2008 ; Saber et al, 2009 ; Sahoo and Gupta, 2014 ) or serve both as disease control agent and biofertilizer ( Ownley and Benson, 1992 ; Dong et al, 2006 ). For example, dry mycelium of P. chrysogenum was successfully used for the control of Fusarium wilt and Verticillium wilt as well as nutrient source in cotton production ( Dong et al, 2006 ).…”

The association of plants and microbial communities is crucial for crop production, and host plants influence the composition of rhizosphere microbiomes. Pulse crops play an important role in the development of sustainable cropping systems, and producers in the Canadian prairies often increase the frequency of pulses in their cropping systems. In this study, we determined the shifts in the fungal community of pea (Pisum sativum L.) rhizosphere, as influenced by the frequency of pulses in rotation, using high throughput sequencing. Six cropping systems containing pea (P), lentil (Lens culinaris Medik., L), hybrid canola (Brassica napus L., C), wheat (Triticum aestivum L., W), and oat (Avena sativa L., O) in different intensities were tested. The fungal communities were assessed at the flowering stage in the fourth and fifth year of the 4-year rotations. Cropping system had a significant impact on the composition of the rhizosphere fungal community, and the effect of crop rotation sequence was greater and explained more of the variation than the effect of previous crops. The rotation with consecutive pulses (WPLP) decreased fungal evenness and increased the proportion of pathotrophs. Fusarium was a dominant and ubiquitous pathotrophic genus. Olpidium virulentus, Botrytis cinerea, Fusarium solani, F. graminearum, and Alternaria eichhorniae were generally more abundant in pulse intensive rotations (WPLP, WLOP, and WPOP), the exception being F. solani which was not promoted by lentil. Reads of O. virulentus and B. cinerea were most abundant in pea preceded by lentil followed by the reads of Mortierella elongata in pea preceded by wheat. Pea consistently had higher grain yield when grown in diversified rotations including wheat, canola/lentil, and oat than rotations with two repeated crops (canola or pea). Cropping system affected the soil physicochemical properties, and soil pH was the main driver of fungal community shift. No evidence of beneficial microorganisms involvement in plant productivity was observed, but the high abundance of pathotrophs in pulse intensified rotations suggests the possibility of pathogen buildup in the soil with increasing pulse frequency. Diversifying rotation sequences minimized disease risk and increased pea production, in this study. Careful selection of plant species appears as a strategy for the management of rhizosphere fungal communities and the maintenance of crop production system’s health.

“…Fungi are prominent inhabitants of the soil microbiota, accounting more biomass than bacteria hence greater ability to solubilize inorganic phosphorous (Sharma et al., 2013). Aspergillus niger, Aspergillus candidus, Aspergillus fumigatus, Aspergillus parasiticus, Aspergillus rugulosus, Penicillium simplicissimum, Pseudeurotium zonatum, Penicillium rubrum, Trichoderma harzianum , and Trichoderma viride are among the widely known phosphate solubilizing fungus (PSF) (Mendes et al., 2014; Sahoo et al, 2014; Zhao &, Lin, 2001).…”

Phosphorus (P), the second most essential nutrient, plays a remarkable role in energy transfer, storage, plant growth, and development. It is the least mobile and accessible to plants in most soil conditions as compared to the other key nutrients. Phosphate‐solubilizing fungus (PSF) plays a vital role in supplying phosphorous to plants from the soil. Hence this research intends to assess the phosphorous and nutritional status of collected soil samples as well as isolation of potential fungal strains. Twelve soil samples were taken from three costal districts of Odisha (Bhadrak, Jajpur, and Balasore). All six key soil parameters like pH, electrical conductivity, organic carbon, nitrogen, phosphorous, and potassium were examined for correlation and found to be significantly associated with each other. Fungal colonies were enumerated, grown and pure colonies were found. A total of four potential fungal strains were isolated, screened from rhizospheric soil and evaluated for their phosphate solubilization efficiency on Pikovskaya's agar selective media. They produce the halo zones around their colony approximately 3.3 cm (PRF2), 2.96(PRF3), and 3.06(PRF4) cm within 10 days of incubation. Aspergillus niger was a highly efficient strain in solubilizing phosphate with the solubilization index (SI) of 3.56 cm and also showed the greatest drop in pH in the PVK broth containing rock phosphate.
