“…This is perhaps because the roots of S. grandis are perennial, while leaves are annual. This is consistent with a hypothesis of predominantly horizontal transmission of endophytes, as old plant tissues would have had more time to accumulate endophytes from the environment (Bertoni and Cabral 1988;Taylor et al 1999;Wang and Guo 2007;Guo et al 2008 ).…”

Endophytic fungi associated with Stipa grandis in the Inner Mongolia steppe were investigated. Thirty-four fungal taxa were identified from plant tissues obtained in four treatments where different plant functional groups were removed. Nine taxa were obtained from leaves and 25 from roots; and no taxa occurred in both leaves and roots. Colonization rates were significantly higher in roots than in leaves. This finding differs from most previous studies and may be due to the small size of the leaves which grow annually, as compared to the roots which persist from year to year under the ground. Alternaria sp. 1 and Pyrenophora sp., both isolated from leaves, were the dominant species in the four treatments. Fusarium redolens was dominant in the roots in treatments I and II, and Phialophora sp. was dominant in treatments III and IV. Horizontal transmission of endophytes may occur between the same and different grass species. This would normally occur through the roots, again accounting for the higher diversity. The results suggest that surrounding plant diversity or plant composition can affect endophyte communities of S. grandis. If endophyte communities alter with change of functional plant groups, then this is likely to affect the dynamics of ecosystem functioning. Global warming and human activities can increase species extinction, therefore, if some functional groups disappear, then the fungi communities will also change.

“…L. chartarum and X. feejeensis were isolated only from twigs of A. marina and B. gymnorrhiza , respectively. These results suggested that some endophytic fungi showed certain tissue preference (Guo et al 2008; Xing et al 2011; Sun et al 2012). …”

“…De Souza Sebastianes et al (2013) reported that the colonisation rate of endophytic fungi was significantly higher in branch than in leaf among three mangrove species in Brazil. The possible explanation might be that the structure and substrates are different between twig and leaf tissues, or that the twigs are more permanent than leaves, which influence the colonisation of endophytic fungi (Taylor et al 1999; Gilbert et al 2002; Wang and Guo 2007; Guo et al 2008). …”

“…For example, Phomopsis fungi were widely isolated from mangroves (Suryanarayanan et al 1998; Suryanarayanan and Kumaresan 2000; Pang et al 2008; Xing et al 2011; Xing and Guo 2011) and non-mangrove plants (Taylor et al 1999; Guo et al 2000, 2008; Cannon and Simmons 2002; Murali et al 2006; Sun et al 2011, 2012). In addition, Pestalotiopsis as generalist fungi were common mangrove endophytes and widely occurred on plants across Palmae, Rhizophoraceae, Planchonellae, and Podocarpaceae in China (Liu et al 2010a, 2012; Xing and Guo 2011; Gong et al 2014).…”

Mangrove forests play an important role in subtropical and tropical coastal ecosystems. Endophytic fungi are widely distributed in various ecosystems and have great contribution to global biodiversity. In order to better understand the effects of mangrove species and tissue types on endophytic fungal community, we investigated cultivable endophytic fungi in leaves and twigs of four mangroves Aegiceras corniculatum, Avicennia marina, Bruguiera gymnorrhiza, and Kandelia candel in Guangxi, China. The four tree species had similar overall colonisation rates of endophytic fungi (24–33%). The colonisation rates of endophytic fungi were higher in twigs (30–58%) than in leaves (6–25%) in the four plant species. A total of 36 endophytic fungal taxa were identified based on morphological characteristics and molecular data, including 35 Ascomycota and 1 Basidiomycota, dominated by Phomopsis, Phyllosticta, Xylaria, Leptosphaerulina, and Pestalotiopsis. The diversity of endophytic fungi was higher in twigs than in leaves in the four plant species. Some endophytic fungi showed host and tissue preference. The endophytic fungal community composition was different among four mangrove species and between leaf and twig tissues.

“…This occurred despite the fact that sampling sites were located in areas subject to differing microenvironments in vivo and in vitro. In vivo microenvironment factors, in particular, have pronounced effects on endophytic microbial communities in plant systems (Guo et al 2008;Martin-Garcia et al 2011).…”

Plants harbors complex and variable microbial communities. Endophytic bacteria play an important function and potential role more effectively in developing sustainable systems of crop production. To examine how endophytic bacteria in sugar beet (Beta vulgaris L.) vary across both host growth period and location, PCR-based Illumina was applied to revealed the diversity and stability of endophytic bacteria in sugar beet on the north slope of Tianshan mountain, China. A total of 60.84 M effective sequences of 16S rRNA gene V3 region were obtained from sugar beet samples. These sequences revealed huge amount of operational taxonomic units (OTUs) in sugar beet, that is, 19-121 OTUs in a beet sample, at 3 % cutoff level and sequencing depth of 30,000 sequences. We identified 13 classes from the resulting 449,585 sequences. Alphaproteobacteria were the dominant class in all sugar beets, followed by Acidobacteria, Gemmatimonadetes and Actinobacteria. A marked difference in the diversity of endophytic bacteria in sugar beet for different growth periods was evident. The greatest number of OTUs was detected during rossette formation (109 OTUs) and tuber growth (146 OTUs). Endophytic bacteria diversity was reduced during seedling growth (66 OTUs) and sucrose accumulation (95 OTUs). Forty-three OTUs were common to all four periods. There were more tags of Alphaproteobacteria and Gammaproteobacteria in Shihezi than in Changji. The dynamics of endophytic bacteria communities were influenced by plant genotype and plant growth stage. To the best of our knowledge, this study is the first application of PCR-based Illumina pyrosequencing to characterize and compare multiple sugar beet samples.
