“…• Zhang et al (1996) have shown that treating cotton seeds with G4 and G6 strains of Gliocladium virens and the GB03 and GB07 strains of Bacillus subtilis suppress the incidence of Fusarium wilt of cotton in soil infested with Fusarium oxysporum f. sp. vasinfectum and Meloidogyne incognita under green house conditions.…”

Abstract:Seed treatment refers to the application of certain agents physical, chemical or biological to the seed prior to sowing in order to suppress, control or repel pathogens, insects and other pests that attack seeds, seedlings or plants and it ranges from a basic dressing to coating and pelleting. Introduction and ban of arsenic (used from 1740 until 1808) is the key milestones in the history of modern seed treatment till then a continuous research and advancement in this technology is going on. The technological advancement prepared a roadmap for refining existing seed treatment technologies and future work on technologies like fluid drilling as a way to sow germinated seeds where gel can also serve as a delivery system for other materials, seed priming advances the early phase of germination without redicle emergence. Another advanced technology, solid matrix priming (SMP) has been evaluated as a means to advances the germination of seeds and serve as a carrier for useful material too. Physical and biological seed treatments alone an alternative to chemicals or in combination with a chemical treatment are being used worldwide because of their environmental safety and socioeconomic aspects. Biological seed treatments are expected to be one of the fastest growing seed treatment sectors in the near future, in part because they are easier to register at Environment Protection Agency (EPA). Lack of awareness to seed treatments at farmer's level is one of the limiting factors in disease management and hence, efforts should be made at farmer's level to adopt the technology. Keeping the all above facts in mind, selected seed treatment technologies with their improvement and significance will be discussed in this review.

“…Certain fungi appear more frequently than others, in particular, the species Aspergillus fumigatus (9.2%), Trichoderma harzianum (6.4%), Mucor hiemalis f. corticolus (3.6%) and Penicillium decumbens (3.6%) appear to be very common (Table 3). Penicillium trzebinskianum (= Penicillium lividum WESTLING) is reported to be a new record for the soil samples from Turkey in addition to the records from foodstuff, cereal and outdoor/indoor air (AYATA 1990, ARAN and EKE 1987, TOPAL 1999 (HOWELL 1982, ZHANG et al 1996.…”

This study involves the isolation and identification of soil borne fungi from different altitudes of Iyidere-Ikizdere vicinity in Rize, Turkey. The qualitative and quantitative fungal composition of the soil of Iyidere-Ikizdere vicinity was surveyed seasonally during a year (between summer 2003 and spring 2004). The soil samples were collected from 10 different locations. Some physical and chemical properties of the soil samples were studied. Soil samples were observed to have the proper pH levels (pH 4.00-6.75) for the growth of microfungi. By using a soil dilution technique, the mycological analysis of 40 soil samples were studied at 25 cm depth. The number of microfungi ranged from 2,000-160,000 CFU g(-1). 249 different microfungi belonging to 15 genera were isolated. 45 of the isolates were Mycelia Sterilia. Penicillium, Aspergillus, Trichoderma and Fusarium were the most abundant genera (26.8%, 14.8%, 9.6% and 8.4%, respectively). Penicillium phialosporum, Penicillium trzebinskianum and Gliocladium virens were reported for the first time in Turkey.

“…Their ability to produce dormant, heat-and desiccation-tolerant spores unlike Gram-negative microbes not only enables them to survive severe stress in the field, but has also led to their utilization in commerce because of the easy dispersal and long shelf life of their spores [5]. Bacillus species reported as having PGP ability include B. subtilis [6][7][8], B. amyloliquefaciens [9], B. pumilus [10], B. licheniformis [11], B. thuringiensis [12], B. cereus [13], B. megaterium [14], and many others.

Bacillus simplex—A Little Known PGPB with Anti-Fungal Activity—Alters Pea Legume Root Architecture and Nodule Morphology When Coinoculated with Rhizobium leguminosarum bv. viciae

Two strains, 30N-5 and 30VD-1, identified as Bacillus simplex and B. subtilis, were isolated from the rhizospheres of two different plants, a Podocarpus and a palm, respectively, growing in the University of California, Los Angeles (UCLA) Mildred E. Mathias Botanical Garden. B. subtilis is a well-known plant-growth promoting bacterial species, but B. simplex is not. B. simplex 30N-5 was initially isolated on a nitrogen-free medium, but no evidence for nitrogen fixation was found. Nevertheless, pea OPEN ACCESSAgronomy 2013, 3 596 plants inoculated with B. simplex showed a change in root architecture due to the emergence of more lateral roots. When Pisum sativum carrying a DR5::GUSA construct, an indicator for auxin response, was inoculated with either B. simplex 30N-5 or its symbiont Rhizobium leguminosarum bv. viciae 128C53, GUS expression in the roots was increased over the uninoculated controls. Moreover, when pea roots were coinoculated with either B. simplex 30N-5 or B. subtilis 30VD-1 and R. leguminosarum bv. viciae 128C53, the nodules were larger, clustered, and developed more highly branched vascular bundles. Besides producing siderophores and solubilizing phosphate, the two Bacillus spp., especially strain 30VD-1, exhibited anti-fungal activity towards Fusarium. Our data show that combining nodulating, nitrogen-fixing rhizobia with growth-promoting bacteria enhances plant development and strongly supports a coinoculation strategy to improve nitrogen fixation, increase biomass, and establish greater resistance to fungal disease.
