“…Strain YC0136 was inoculated on organophosphorus medium and cultured at 30 • C for 7 days until a transparent circle formed around the colonies. The ratio of transparent circle diameter (D)/colony diameter (d) indicated the capacity for phosphate solubilization (Kanse et al, 2015).…”

Paenibacillus polymyxa is an important member of the plant growth-promoting rhizobacteria. P. polymyxa YC0136 inoculation had beneficial effect on growth promotion and biological control of tobacco (Nicotiana tabacum L.) under field conditions. This study aimed to reveal the growth-promoting mechanisms of strain YC0136. In growthpromotion assays, tobacco plant height was increased by 8.42% and 8.25% at 60 and 90 days, respectively, after inoculation with strain YC0136. Strain YC0136 also promoted the accumulation of tobacco biomass in varying degrees. Following inoculation with strain YC0136, 3,525 and 4,368 tobacco genes were up-regulated and down-regulated, respectively. Strain YC0136 induced the expression of plant hormone-related genes in tobacco, including auxin, cytokinin, and gibberellin, as well as transcription factors related to stress resistance such as WRKY and MYB. In addition, strain YC0136 induced the up-regulation of genes in the phenylpropanoid biosynthesis pathway by 1.51-4.59 times. Interaction with tobacco also induced gene expression changes in strain YC0136, with 286 and 223 genes up-regulated and down-regulated, respectively. Tobacco interaction induced up-regulation of the ilvB gene related to auxin biosynthesis in strain YC0136 by 1.72 times and induced expression of some nutrient transport genes. This study contributes to our understanding of the growth-promoting mechanisms of strain YC0136 on tobacco and provides a theoretical basis for the application of P. polymyxa YC0136 as a biological fertilizer.

“…(2011) transferred the accepted species of Penicillium subgenus Biverticillium into Talaromyces and Houbraken & Samson (2011) transferred Eupenicillium species into Penicillium . This was well received by the general community working on these fungi ( Houbraken et al. 2011a,b, Visagie & Jacobs 2012, Visagie et al.…”

As part of a worldwide survey of the indoor mycobiota, dust was collected from nine countries. Analyses of dust samples included the culture-dependent dilution-to-extinction method and the culture-independent 454-pyrosequencing. Of the 7 904 isolates, 2 717 isolates were identified as belonging to Aspergillus, Penicillium and Talaromyces. The aim of this study was to identify isolates to species level and describe the new species found. Secondly, we wanted to create a reliable reference sequence database to be used for next-generation sequencing projects. Isolates represented 59 Aspergillus species, including eight undescribed species, 49 Penicillium species of which seven were undescribed and 18 Talaromyces species including three described here as new. In total, 568 ITS barcodes were generated, and 391 β-tubulin and 507 calmodulin sequences, which serve as alternative identification markers.

“…Notably, A. tubingensis was able to solubilize rock phosphate with an efficiency above 97.5% under the range of 0.5 to 3.0% NaCl (Table 2), while T. islandicus had an efficiency above 92.8% in a lower range (0.5 to 1.0% NaCl). P-solubilizing capability under salt stress conditions has also been reported for A.s niger (Xiao et al 2013), A. terreus (Srinivasan et al 2012), and T. funiculosus (Kanse et al 2015). The tolerance to saline stress has been associated to changes in plasma membrane fluidity and mechanisms for K + /Na + exchange to regulate intracellular ion homeostasis (Gunde-Cimerman et al 2009;Santander et al 2019).…”

“…Similarly, Xiao et al (2013) demonstrated the capability of Aspergillus niger WHAK1 to solubilize rock phosphate over a wide range of temperature, pH, salinity, and desiccation. Srinivasan et al (2012) demonstrated the capability of Aspergillus terreus to solubilize rock phosphate under salt stress, and Kanse et al (2015) found a similar performance in Talaromyces funiculosus under different concentrations of NaCl, as well as a relatively high tolerance to the presence of fungicides. Therefore, stress-tolerant fungi are of particular interest to improve the availability of P in crops under changing environmental conditions (Babu and Reddy 2011;Xiao et al 2013).…”

“…In addition, A. tubingensis reduced its P solubilization efficiency to 5.5% when exposed to 100 mg L −1 of carbendazim, while T. islandicus kept its performance above 82.7%. It has been reported that T. funiculosus had a P solubilization efficiency of 45.2% exposed to 12.5 mg L −1 of carbendazim (Kanse et al 2015). In the same study, T. funiculosus was able to solubilize phosphate in the presence of mancozeb or hexaconazole.…”

The purpose of this study was to evaluate the capability of Aspergillus tubingensis and Talaromyces islandicus to solubilize inorganic phosphorus sources, their activity under abiotic stress, and the enhancement of P availability in soils and plant growth. The P-solubilizing capability and acidification mechanism of the strains were assessed in vitro using tricalcium phosphate and rock phosphate. Independent assays were conducted with rock phosphate under NaCl and fungicides carbendazim, chlorothalonil, and propamocarb hydrochloride using a factorial design. Thereafter, the effects of fungal inoculations in rock phosphate-amended soil and P nutrition of Zea mays were assessed in a greenhouse experiment. Both fungi solubilized P in vitro via acidification through the exudation of acetic, citric, lactic, malic, quinic, and succinic acids. The P-solubilizing efficiency of A. tubingensis was maintained above 97.5% under 0.5 to 3.0% NaCl, up to 28.7% in the treatment with carbendazim, up to 5.3% with chlorothalonil, and above 96.5% with propamocarb hydrochloride; while T. islandicus efficiency decreased to 45.2% in a NaCl concentration-dependent trend, and maintained it above 80% in the fungicide treatments. The inoculation with A. tubingensis increased the available P in the amended soil by up to 65% after 30 days and resulted in 87% higher foliar P content, 111% greater plant height, and 25% greater dry weight of maize shoots. Similarly, T. islandicus contributed to these parameters in 55, 67, 90, and 17%, respectively. These findings suggest their potential as qualified phosphorus solubilizing microorganisms to develop novel and sustainable approaches for P fertilization in agriculture.
