“…Omar et al (2006) similarly reported FCRR reduction from a combination of Burkholderia cepacia with a reduced rate of the fungicide carbendazim in the UK. The integration of Bacillus subtillis (Companion ® ) with either the fungicide hymexazol or the resistance elicitor acibenzolar-s-methyl produced greater reductions in the FCRR disease index than any of the treatments alone (Myresiotis et al, 2012). Integration of Trichoderma harzianum with the resistance elicitor chitosan resulted in enhanced management of FCRR in a greenhouse trial in Tunisia (ElMohamedy et al, 2014).…”

Integration of different methods for sustainable management of Fusarium wilt of tomato revealed that all the treatments were able to significantly reduce the disease severity over control. Among the treatments, the minimum disease severity was recorded in the T 3 treatment where treatment was given as seed treatment with T. harzianum + soil application of neem cake powder + foliar spray of carbendazim, representing the value 4.82, 8.23, 12.37 and 16.37 per cent against 10.75, 14.84, 20.00 and 25.75 per cent in case of control at 30, 45, 60 and 75 days age of plant, respectively. Integrated approach has also been able to increase shoot length as 27.00, 42.15, 54.98, and 65.07 cm at 30, 45, 60 and 75 days age of plant, respectively whereas in case of control it was 18.60, 25.70, 34.63 and 44.29. Similarly, fresh and dry shoot and root weight have also been found increased in case of integrated approaches. Biochemical analysis of the treated plants revealed that highest soluble protein and total phenol content is observed in T3 treatment (Seed treatment with T. harzianum + soil treatment with neem cake powder and foliar spray with carbendazim), showing 37.85, 36.78 and 35.76 mg/gm of fresh leave of protein and 2.40, 2.14 and 2.04 mg/gm of fresh leave of phenol at 30, 45 and 60 days age of plant. As per yield is concerned, it has found that the maximum yield was obtained per plant from the treatment given as seed treatment with T. harzianum + soil treatment with neem cake powder + foliar spray with carbendazim, showing the value of 500 g per plant which was followed by the treatment given as seed treatment with T. harzianum + soil treatment with neem cake powder + foliar spray with neem leaf extract showing 470 g per plant.

“…Bacillus pumilus, a Gram-positive bacterium belonging to the B. subtilis group (8), has been widely used as a plant growth-promoting rhizobacterium to prevent plant disease caused by pathogenic bacteria and fungi (9). However, numerous B. pumilus strains have also been reported to cause several human and plant diseases (10,11).…”

We characterized two newly isolated myoviruses, Bp8p-C and Bp8p-T, infecting the ginger rhizome rot disease pathogen Bacillus pumilus GR8. The plaque of Bp8p-T exhibited a clear center with a turbid rim, suggesting that Bp8p-T could transform into latent phage. Lysogeny assays showed that both the two phages could form latent states, while Bp8p-T could form latent phage at a higher frequency and stability than Bp8p-C. The genomes of Bp8p-C and Bp8p-T were 151,417 and 151,419 bp, respectively; both encoded 212 putative proteins, and only differed by three nucleotides. Moreover, owing to this difference, Bp8p-C encoded a truncated, putative actin-like plasmid segregation protein Gp27-C. Functional analysis of protein Gp27 showed that Gp27-T encoded by Bp8p-T exhibited higher ATPase activity and assembly ability than Gp27-C. The results indicate that the difference in Gp27 affected the phage lysogenic ability. Structural proteome analysis of Bp8p-C virion resulted in the identification of 14 structural proteins, among which a pectin lyase-like protein, a putative poly-gamma-glutamate hydrolase, and three proteins with unknown function, were firstly identified as components of the phage virion. Both phages exhibited specific lytic ability to the host strain GR8. Bp8p-C showed better control effect on the pathogen in ginger rhizome slices than Bp8p-T, suggesting that Bp8p-C has a potential application in bio-control of ginger rhizome rot disease. Bacteriophages (phages) are viral predators of bacteria that propagate by infecting the host (1) and, based on the mode of replication of the phage genome, they are classified as lytic or lysogenic phages. To maintain the lysogenic state, phage gene expression is regulated by the phage lysogenic regulatory system. The lytic switch mechanism of the temperate phage has been well studied (2), which illustrates the classical lysogen conversion mechanism of and similar phages. Several other strategies for phage lysogenic conversion have also been observed. For example, a single nucleotide mutation in the LexA-binding site of phage SPC32H induces phage SPC32H to maintain the lysogenic state (1). According Yoshihiko et al., a temperate phage, c-st, with a linear genome can transform into a circular plasmid prophage in the host, Clostridium botulinum, which provides phage c-st the ability to exhibit unstable lysogeny (3). Meanwhile, the TubZ-like plasmid segregation system protein encoded by c-st is essential for partition of the prophage plasmid (4).Plasmid segregation systems are essential for accurate partition of large and essential plasmids to daughter cells during cell division (5). The plasmid segregation system typically consists of three components: a centromere-like DNA region, a small DNA-binding adaptor protein, and a nucleotide-driven motor protein with NTPase activity. Based on the nature of the motor proteins, three major classes of segregation systems have been identified to date and can be described as ParA-like system (type I, ParABS system), ParM-like system (type...

Evaluation of plant‐growth‐promoting rhizobacteria, acibenzolar‐S‐methyl and hymexazol for integrated control of Fusarium crown and root rot on tomato

Abstract: The results of the study indicate that, when bacilli PGPR strains were combined with pesticides, there was an increased suppression of Forl on tomato plants, and thus they may prove to be important components in FCRR integrated management.
