Effects of the fungal endophyte Phomopsis liquidambari on nitrogen uptake and metabolism in rice

Improvement of nitrogen accumulation and metabolism in rice (Oryza sativa L.) by the endophyte Phomopsis liquidambari

“…Lyons et al (1990) also reported that the infection of tall fescue by the fungal endophyte Acremonium coenophialum resulted in a mean increase in GS activity of 32%; however, no significant effect on NR activity was observed in tall fescue. The solution culture results of our previous study (Yang et al, 2014) showed that the N metabolism-relevant genes (OsNR1, OsGS1, OsGS2, OsNADH-GOGAT) of young rice seedlings were up-regulated in P. liquidambari-infected plants under low N treatment. Sherameti et al (2005) found that the endophytic fungus Piriformospora indica could stimulate N accumulation by enhancing the expression of NR in plant roots.…”

“…Our previous study used quantitative PCR to estimate endophyte densities in roots and in shoots of infected and uninfected rice plants grown under three N levels and found that the endophyte density was significantly reduced in roots and in shoots with increased N levels (Yang et al, 2014). In Lolium perenne, Rasmussen et al (2007) also found that a high N supply reduced the fungal endophyte density.…”

“…Previous work in a growth chamber hydroponic study reported a strong and complex rice seedling transcriptional response to P. liquidambari, and this endophyte stimulated the expression of several genes involved in N uptake and metabolism in rice seedlings, suggesting the beneficial effects of P. liquidambari concerning N use in rice plants (Yang et al, 2014). However, the duration of the hydroponic experiment was short in comparison with the natural life span of the rice host, and the growth environment of hydroponic rice is controlled.…”

“…Our previous research indicated that the fungal endophyte Phomopsis liquidambari could produce 3-indoleacetic acid, abscisic acid, and vitamin B1 in vitro Chen et al, 2011). Cross host species inoculation of rice with P. liquidambari revealed that this endophyte forms a mutualistic symbiotic relationship with rice, promotes the growth and yield of rice, and significantly reduces the required amount of soil N fertilizer (Yuan et al, 2007;Li et al, 2009;Yang et al, 2014).…”

Biomass yield, nutritive value and accumulation of minerals in Trifolium subterraneum L. as affected by fungal endophytes

“…These effects could be a consequence of the substantial benefits that endophytic fungi may confer on hosting plants, such as drought tolerance (Hall et al 2014), resistance to herbivory and pathogens (Thom et al 2013;Romeralo et al 2015), enhanced nutrient uptake (Yang et al 2014), and increased competitive ability (Vázquez-de-Aldana et al 2013). However, this influence appears to be variable and clearly dependent on the species of endophyte, the host genotype and environmental conditions (Ahlholm et al 2002).…”
