    Abstract Iva xanthiifolia, an invasive annual weed species native to North American prairies, is an agricultural problem in different parts of the world and represents a health hazard as an allergen to humans. This study addresses the limited literature on its germination requirements, focusing on base temperature, base water potential, and salinity tolerance. Seeds from a Serbian population near Belgrade were tested to various conditions. The experiments were conducted using temperatures ranging from 1 °C to 30 °C and water potentials ranging from 0 to –2 MPa, while salinity tolerance was tested at three temperatures (1, 3, and 6 °C) and five salinity levels (0 to 16 dS/m). Results indicate higher germination rates at lower temperatures (1 °C) compared to higher temperatures (30 °C), with a base temperature of 0.7 ± 0.37 °C. Germination decreased with increased water potential, showing a base water potential of -1.58 ± 0.07 MPa. Salinity tolerance was observed, with germination even at 16 dS/m (the final germination rate was 54.5 % ±2.88). Additionally, germination was observed declining with increasing temperature in a saline environment. As germination is one of the major determinants of a species’ success, the possible spreading of this species under different climate change scenarios was simulated. Results of future distribution modelling suggested sensitivity to precipitation changes and potential northward expansion of this species. This research enhances our understanding of Iva xanthiifolia traits, useful for supporting management strategies for its control and mitigation of its impact, even under future climate change and land-use scenarios.

    Abstract Environmental factors like temperature and soil humidity are recognized as influencing factors on photosynthetic response and organic productivity, distribution and biochemical characteristics of plants. Here we present measurements of gas exchange parameters, water-use efficiency (WUE) and nitrogen-use efficiency (NUE) of field-grown invasive species Ambrosia artemisiifolia L., Ambrosia trifida L. and Iva xanthifolia Nutt., in order to define their potentials as colonizers. Biogenic volatile organic compounds (BVOC) in leaves and flowers depending on soil humidity were also investigated. Results indicated species A. artemisiifolia as the colonizer with the highest physiological potential because of its high WUE in its vegetative phase and also the highest NUE and the highest photosynthesis/dark respiration ratio in its flowering phenological phase. It was found that the volatile compounds of Ambrosia species and Iva xanthifolia consist mainly of terpenic compounds. There was a significant difference among the species regarding qualitative composition of monoterpens and sesquiterpens and specific qualitative and quantitative ratio of monoterpens in flowers and leaves of A. artemisiifolia.

    Abstract Bacillus species are among the most researched and frequently applied biocontrol agents. To estimate their potential as environmentally friendly microbial-based products, reliable and rapid plant colonization monitoring methods are essential. We evaluated repetitive element-based (rep) and Random Amplified Polymorphic DNA (RAPD) PCR (Polymerase Chain Reaction) genotyping in a diversity assessment of 251 strains from bulk soil, straw, and manure samples across Serbia, highlighting their discriminative force and the presence of unique bands.

    Abstract In recent years, countries in Southeast Europe are facing climate changes characterized by extreme hot weather, which contribute to the increased frequency of Aspergillus species. Because of these changes, Aspergillus parasiticus was isolated, for the first time, from maize grain in Serbia (Nikolic et al, 2018). The presence of black powdery mycelia on maize ears indicated occurrence of species of the genus Aspergillus section Nigri, which led to the need for detailed identification of these fungi. Disease incidence ranged from 10 and 15% in August 2013. Maize ears with black powdery symptoms were collected from field in Zemun Polje, Serbia. Symptomatic kernels were surface sterilized with 1% sodium hypochlorite solution for 3 min, rinsed three times with sterilized water, then incubated at 25°C in the dark for 7 days on potato dextrose agar (PDA). Twenty isolates were identified as genus Aspergillus section Nigri. Monospore cultures formed black cottony colonies with a yellowish border on PDA. The average colony diameter was 50 mm. In order to reliably identify, isolates were transferred to Malt Extract agar (MEA) and Czapek Yeast Autolysate agar (CYA) (Samson et al, 2014). On CYA fungal colonies consisted of a white mycelium, covered by a layer of black conidiophores. On MEA fungal colonies were dense, black, with yellowish border. The reverse side was colorless to pale yellow, with a yellow ring in the middle. The average size of conidia was 4.3 µm. The conidia were globose to sub-globose, smooth to roughened, which coincides with previous research (Silva et al, 2020). Given that the fungi Aspergillus niger and Aspergillus welwitschiae are morphologically indistinguishable (Susca et al, 2016), species level identification was completed by analysis of a partial sequence of the internal transcribed spacer (ITS) region (ITS1/ITS4 primers) and calmodulin gene (CMD5/CMD6 primers) (Samson et al., 2014). The sequences were compared with the sequences of A. welwitschiae strains registered in the GenBank database based on nucleotide similarity, and results showed 99,64 and 100% similarity with ITS (OL711714) and calmodulin (KX894585), respectively. The sequence was deposited in GenBank with accession numbers OQ456471 (ITS) and OQ426518 (calmodulin). We also confirmed the presence of this species with specific primers (AWEL1/AWEL2) designed by Susca et al. 2020. Pathogenicity test was performed in Zemun Polje on the same maize hybrid from which the fungal species was isolated. Using artificial inoculations by the injecting conidial suspension into the silk channel, three days after 50% of plants reached the silking stage. Twenty ears were inoculated with each isolate, in four replicates (Reid et al, 1996). Inoculum was prepared from 7-day-old colonies on PDA, and 2 ml of a conidial suspension (1×106 spores/ml) was used. Control plants were inoculated with sterile water. All inoculated ears showed symptoms, similar to those from field infections. Control ears were symptomless. The fungus was reisolated and was morphologically identical to the original isolates, thus completing Koch's postulates. Based on molecular, morphological and pathogenic properties, the isolates were identified as A. welwitschiae. This is the first report of A. welwitschiae as the causal agent of black maize ear rot not only in Serbia, but also in the other countries of the Western Balkans. Given that the fungus A. welwitschiae synthesizes both ochratoxin A (OTA) (Battilani et al, 2006) and fumonisin (FB) (Frisvad et al, 2011), further studies should be focused on assessment its aggressiveness and toxicological profile.

    Abstract The diversity of plant-associated bacteria is vast and can be determined by 16S rRNA gene metabarcoding. Fewer of them have plant-beneficial properties. To harness their benefits for plants, we must isolate them.

    Abstract Bacillus species are among the most researched and frequently applied biocontrol agents. To estimate their potential as environmentally friendly microbial-based products, reliable and rapid plant colonization monitoring methods are essential. We evaluated repetitive element-based (rep) and Random Amplified Polymorphic DNA (RAPD) PCR (Polymerase Chain Reaction) genotyping in a diversity assessment of 251 strains from bulk soil, straw, and manure samples across Serbia, highlighting their discriminative force and the presence of unique bands. RAPD 272, OPG 5, and (GTG)₅ primers were most potent in revealing the high diversity of a sizable environmental Bacillus spp. collection. RAPD 272 also amplified a unique band for a proven biocontrol strain, opening the possibility of Sequence Characterized Amplified Region (SCAR) marker design. That will enable colonization studies using the SCAR marker for its specific detection. This study provides a guide for primer selection for diversity and monitoring studies of environmental Bacillus spp. isolates.
