“…In plants, it is a key enzyme in the biosynthesis of flavonoids (Knogge, Schmelzer and Weissenböck 1986; Dao, Linthorst and Verpoorte 2011) that has been shown to possess antimicrobial activity (Orhan et al . 2010; Mousa and Raizada 2013), playing a role in plant defense against pathogens. Nevertheless, no differences were found in the RNA accumulation levels of chitinases and TLPs, but one CHS was significantly downregulated in planta (Fig.…”

Dark septate endophytes (DSEs) present a group of widespread root-colonizing fungi. The role of these endophytes in ecosystems and their interactions with plant pathogens are not well understood. In the current study, we assessed the antagonistic potential of the model DSE Cadophora sp. against the tomato soilborne pathogens Rhizoctonia solani, Pythium aphanidermatum and Verticillium dahliae. To investigate their interactions, we conducted in vitro assays followed by a greenhouse experiments in which tomato plants were inoculated with different combinations of the DSE and pathogens. RNA accumulation of selected tomato pathogenesis-related genes and of Cadophora sp. genes with putative antifungal function was analyzed. Cadophora sp. inhibited the growth of the fungal pathogens in vitro and vice versa; a negative impact of the pathogens on the growth of the DSE was also detected. In roots, however, this mutual negative interaction could not be observed. Expression analyses of plant genes could not explain this differential effect, but among the Cadophora sp. genes analyzed, a gene coding for a chalcone synthase was downregulated in planta. The data indicate that plants can change the interaction between fungi and, therefore, in vitro detected antagonism does not necessarily reflect the situation inside the plant.

Purpose The high salt content in soil decreases soil structure and fertility. We inquired the effects of manure combined phosphorus (P) fertilizer on the soil organic carbon (SOC) stock, soil aggregate stability and P availability in coastal saline-alkali soil. Methods A 2-year field experiment was arranged with manure and P fertilization in saline-alkaline soil of Yellow River Delta including: four manure treatments (C0, C1, C2 and C3, which was 0, 500, 1000 and 2000 kg C ha− 1, respectively) under two P fertilization levels (P1 and P2, which was 105 and 75 kg P ha− 1, respectively). Results Compared with C0 treatment, soil available P (AP) and microbial P in C2 treatment was significantly increased under the two P levels (p < 0.05). Under same C treatment, optimized P application did not significantly reduce soil AP pool. Under the two P levels, compared with C0 treatment, the mean weight diameter and > 0.25 mm aggregates proportion were significantly increased in C2 treatment (p < 0.05). As the binder for macroaggregates formation, SOC stock was increased by 5.98% and 5.11% in P1C2 and P2C2 treatments, respectively. And humus content increased with manure application. The fulvic acid (FA) content in C3 treatment was highest. However, the humin (HU) content in C2 treatment was highest. This might be because the increase of FA improved the activity of microorganisms and decomposed part of HU. Soil physicochemical properties were increased with manure application. Conclusions Appropriate manure and optimized P fertilizer was conducive P availability, increased aggregate stability and SOC stock.
