“…Yeasts are unicellular fungi that can also be found in the rhizosphere of plants, but in smaller numbers compared to bacteria and filamentous fungi; however, little information is known about their function in this ecosystem. A wide variety of yeasts present characteristics that promote plant growth (Cloete et al, 2009;Limtong et al, 2014;Nutaratat et al, 2014) via the control of plant pathogens (El-Tarabily, 2004;El-Tarabily and Sivasithamparam, 2006;Korres et al, 2011;Rosa et al, 2010), the production of phytohormones (Nassar et al, 2005), the solubilization of phosphate (Hesham and Mohamed, 2011;Falih and Wainwright, 1995;Mirabal Alonso et al, 2008;Mundra et al, 2011), the oxidation and mineralization of nitrogen and sulfur compounds (Falih and Wainwright, 1995), the production of siderophores (Sansone et al, 2005) and the stimulation of root colonization by mycorrhizal fungi (Mirabal Alonso et al, 2008;Vassileva et al, 2000).…”

-Rhizosphere and phylloplane yeasts are able to produce phytohormones, acting as potential plant growth promoters. The aim of this study was to analyze the production of indole acetic acid (IAA) by yeasts using variations in the culture conditions. The yeasts evaluated were Rhodotorula mucilaginosa and Trichosporon asahii, which were cultivated in a potato broth medium with 20 g/L of glucose or sucrose as the carbon source. The cultivation was carried out at 22°C, 25°C or 30°C, and the initial pH was adjusted to 3.0, 4.5 or 6.0. The cultures were analyzed using a colorimetric technique with Salkowski reagent. The cell count was determined in all of the conditions. The results for T. asahii showed that IAA production with sucrose was superior at pH 6.0, and that with glucose was superior at pH 4.5. These results indicate an association between the carbon source and medium pH. Rh. mucilaginosa (2F32) presented a high IAA production when compared with T. asahii (3S44 and 4C06) or even with other microorganisms referenced in the literature. The highest production (0.655 g/L) was obtained at pH 6.0 with glucose as the carbon source. Variations in the culture conditions did not affect the cell growth of the yeasts.

“…Several hypotheses have been proposed to explain this intriguing phenomenon of inhibition between Candida species, such as competition for food and space, dissemination of inhibitory chemicals produced in the association and even the existence of mediators or molecular messengers that are able to reduce factors related to the virulence of C. albicans (Korres et al 2011;Rossoni et al 2015;Thein et al 2007b). Furthermore, according to Thein et al (2007b), the effect of C. krusei on C. albicans filamentation may be due to competitive adhesion in the early stages of biofilm formation, restricting populations of C. albicans and thereby the formation of hyphae.…”

Candida krusei and Candida glabrata reduce the filamentation of Candida albicans by downregulating expression of HWP1 gene

Pathogenicity of Candida albicans is associated with its capacity switch from yeast-like to hyphal growth. The hyphal form is capable to penetrate the epithelial surfaces and to damage the host tissues. Therefore, many investigations have focused on mechanisms that control the morphological transitions of C. albicans. Recently, certain studies have showed that non-albicans Candida species can reduce the capacity of C. albicans to form biofilms and to develop candidiasis in animal models. Then, the objective of this study was to evaluate the effects of Candida krusei and Candida glabrata on the morphogenesis of C. albicans. Firstly, the capacity of reference and clinical strains of C. albicans in forming hyphae was tested in vitro. After that, the expression of HWP1 (hyphal wall protein 1) gene was determined by quantitative real-time PCR (polymerase chain reaction) assay. For both reference and clinical strains, a significant inhibition of the hyphae formation was observed when C. albicans was incubated in the presence of C. krusei or C. glabrata compared to the control group composed only by C. albicans. In addition, the culture mixed of C. albicans-C. krusei or C. albicans-C. glabrata reduced significantly the expression of HWP1 gene of C. albicans in relation to single cultures of this specie. In both filamentation and gene expression assays, C. krusei showed the higher inhibitory activity on the morphogenesis of C. albicans compared to C. glabrata. C. krusei and C. glabrata are capable to reduce the filamentation of C. albicans and consequently decrease the expression of the HWP1 gene.

“…The first one has a broad spectrum of action, and its function is to inhibit sterol biosynthesis in the plasma membrane, resulting in the alteration of cell formation and structure [7,10,11,12,13]. While the second group inhibits the cell division mechanism (mitosis), by disrupting the tubulin biosynthesis and the mitotic spindle, consequently [6,11,12,14]. In this way, one of the significant advantages associated with the use of azoles is the food preservation against fungi growth and the protection of plants from fungal diseases, increasing thus the production yield [15].…”

Fungi are the primary infectious agents in plants causing significant economic losses in agroindustry. Traditionally, these pathogens have been treated with different synthetic fungicides such as hydroxianilides, anilinopyrimidines, and azoles, to name a few. However, the indiscriminate use of these chemicals has increased fungi resistance in plants. Natural products have been researched as a control, and an alternative to these synthetic fungicides since they are not harmful to health and contribute to the environment caring. This review describes plants extracts, essential oils, and active compounds or secondary metabolites as antifungal agents both, in vitro and in vivo. Active compounds have been recently described as the best candidates for the control of phytopathogenic fungi. When metabolized by plants, these compounds concentrations rely on the environmental conditions and pathogens incidence. However, one issue regarding the direct application of these preformed compounds in plants touch upon their low persistence in the environment, and their even lower bioavailability than synthetic fungicides. Hence the challenge is to develop useful formulations based on natural products to increase the compounds solubility facilitating thus their application in the field while maintaining their properties.
