“…Producing ACC deaminase was reported as an important mechanism for PGPB to resist stress for host plants [27], while in this study, most of the strains producing ACC deaminase didn't play an effective role in promoting plant growth. It may be because the slow drying in this study did not promote ethylene production.…”

Two hundred and thirty-two bacterial strains were isolated from the rhizospheric soil of Populus euphratica which is the dominant tree living in extreme arid regions in northwest China. Some strains with plant growth-promoting bacteria related metabolic characteristics were able to promote drought resistance in plants after inoculation. Ten strains with the greatest effects increased the dry weight of wheat shoots from 0.5 to 34.4 %, and the surface area of the root systems from 12.56 to 212.17 % compared to the control after drought treatment whereas no obvious promoting effect was observed in normal water conditions. These 10 strains were identified to be of the genera Pseudomonas, Bacillus, Stenotrophomonas and Serratia by 16S rRNA (rrs) gene sequence alignment. Among these strains, Serratia sp. 1-9 and Pseudomonas sp. 5-23 were the two most effective strains. Both of them produced auxin and the production increased significantly when cultured under simulated drought conditions which are inferred to be the most plausible mechanism for their plant growth-promoting effect under drought stress.

“…Because of their spore-forming ability, they could resist adverse ecological conditions, and this feature is evident in the isolates obtained from L. perfoliatum growing in extreme drought, saline, heat and alkali conditions. This kind of abundance has also been observed in endophytic bacteria from roots of the halophyte P. strombulifera (Sgroy et al 2009). …”

Li Y., Cheng C., An D. (2017): Characterisation of endophytic bacteria from a desert plant Lepidium perfoliatum L. Plant Protect. Sci., 53: 32-43.Sixty-two endophytic bacteria from the leaves, roots, and stems of healthy Lepidium perfoliatum L. were isolated and characterised. From the results, 89, 87, 90, and 97% isolates could tolerate 12% NaCl, 30% PEG 6000, 50°C and pH 10, respectively. 74% isolates could form a biofilm. Besides, 28 isolates could improve the germination rate of host seeds under different degree of drought stress. These data suggest that the endophyte isolates show considerable resistance to abiotic stress and assist their plant hosts to germinate under drought stress.

“…and P. variotti. In another study, Sgroy et al (2009) used A. alternata to show that two endophytic bacteria (Brevibacterium halotolerans, Bacillus pumilus) isolated from Prosopis strombulifera, can inhibit fungal growth. Hui et al (2012) isolated one endophytic species (Bacil lus subtilis) from Prunus mume with antifungal properties against A. alternata and Fusarium sp.…”

A b s t r a c tA total of 181 cultivable endophytic bacterial isolates were collected from stems of 13 species of herbs inhabiting Europe (Poland): Chelido nium majus L., Elymus repens L., Erigeron annuus L., Euphrasia rostkoviana Hayne, Foeniculum vulgare L., Geranium pratense L., Humulus lupulus L., Matricaria chamomilla L., Mentha arvensis L., Papaver rhoeas L., Rosmarinus officinalis L., Solidago gigantea L. and Vinca minor L. The isolates were screened for their antifungal activity and fifty three were found to inhibit fungal growth. Of these, five had strong antifungal properties. These selected isolates were identified as: Pseudomonas azotoformans, P. cedrina, Bacillus subtilis group and Erwinia persicina. 370In the past few years the search for endophytes inhabiting medicinal plants intensified. It is now recognized that herbs are a very rich source of microorganisms with different biochemical properties. Numerous recent studies have been devoted to the identification of endophytes colonizing herbs from Asian countries. One study isolated 18 endophytic bacteria from herbal plants in Indonesia, such as citrus, turmeric, Androgra phis paniculata and Piper crocatum (Soka et al., 2012). Another study obtained 19 bacterial endophytes and 113 fungal endophytes from plants grown in India: Digitalis lanata, Digitalis purpurea, Plantago ovata and Dioscorea bulbifera (Ahmed et al., 2012). Indian herbs were also investigated by Amirita and colleagues, who managed to isolate 334 fungal strains inhabiting the internal tissues of Adhatoda vasica, Costus igneus, Coleus aromaticus and Lawsonia (Amirita et al., 2012). Another study of medicinal plants grown in Taiwan isolated 156 fungal endophytes from 20 species from the Lauraceae and Rutaceae family (Ho et al., 2012). In 2014 our team presented endophytic microflora of Hypericum perforatum (Rekosz-Burlaga et al., 2014). From stems and leaves of the tested plants four bacterial strains were isolated.The aim of the present study was to describe the endophytic microflora of selected medicinal plants inhabiting European countries. Isolated bacteria were tested for their antifungal properties against a plant pathogenic fungi and strains displaying the greatest antifungal activity have been classified according to their morphological, physiological and molecular characteristics.Plant samples were collected from two areas in central Poland, near Kozienice town (51.575°N, 21.750°E) and in Warsaw city (52.259°N, 21.020°E), during the vegetative seasons of 2007 and 2008. Bacterial endophytes were isolated from stems of 13 native growing herbal plant species: Chelidonium majus L., Elymes repens L., Erigeron annuus L., Euphrasia rostkoviana Hayne, Foeniculum vulgare L., Geranium pratense L., Humulus lupulus L., Matricaria chamomilla L., Mentla arvensis L., Papaver rhoeasL., Rosmarinus officinalis L. Solidago gigantea L. and Vinca minor L. Bacterial isolation from plant material was performed according to the procedure of Hung and Annapurna (2004). Five plants of each species were...
