AbstractDysregulation or crosstalk of signal transduction pathways contributes to disease development. Despite the initial success of identifying causal links between source and target proteins in simple or well-studied biological systems, it remains challenging to investigate alternative pathways specifically associated with a disease. We develop a Gene network-based integrative approach for Inferring disease-associated signaling Pathways (GIP). Specifically, we identify alternative pathways given source and target proteins. GIP was applied to human breast cancer data. Experimental results showed that GIP identified biologically meaningful pathway modules associated with antiestrogen resistance.

Putting Green

Sand topdressing is applied to maintain or enhance playability of the turf surface of putting greens. Anthracnose is a devastating disease of annual bluegrass (ABG; Poa annua) putting green turf, caused by Colletotrichum cereale. The disease is more severe on weakened turf and reputed to be exacerbated by management practices that wound turf. A 2-year field study was initiated in 2007 to evaluate the effects of foot traffic (0 versus 327 footsteps m−2, equivalent to 200 rounds day−1) and sand topdressing (0 and 0.3 liter m−2 every week) on anthracnose severity of ABG mowed at 3.2 mm. Surprisingly, foot traffic reduced anthracnose severity as much as 28%, regardless of sand topdressing, during both years. Although sand topdressing initially increased disease severity (up to 7%) in 2007, continued applications decreased severity by 9% later in August 2007 and again in 2008. The treatment combination of foot traffic 5 days week−1 and weekly sand topdressing resulted in the best turf quality by the end of both seasons. Results indicate that the practice of sand topdressing can be continued even under conditions of intense foot traffic and anthracnose disease development on ABG putting greens.

Colletotrichum species cause anthracnose disease on the economically important spice crop chili. A total of 24 Colletotrichum species are known to infect chili and cause anthracnose. C. scovillei belongs to the C. acutatum species complex, and it shows greater aggressiveness than other species, particularly in the case of inoculation onto the nonwounded fruits of chili plants. The current work introduces an initial Illumina-Nanopore hybrid draft genome for C. scovillei TJNH1 together with the related annotations. Knowledge of this genome sequence provides an important reference genome of C. scovillei and will help further understand the pathogenic mechanism of C. scovillei to plant.

Abstract. Darmadi AAK, Suprapta DN, Khalimi K. 2020. Potential antagonistic rhizobacteria to control Colletotrichum scovillei, the cause of anthracnose disease in chili pepper. Biodiversitas 21: 2727-2734. Six species of Colletotrichum were identified as the cause of anthracnose disease on Bali Island, Indonesia in 2018. These species were C. scovillei, C. acutatum, C. nymphaeae, C. gloesporioides, C. truncatum, and C. fructicola. Among them, C. scovillei was the most prevalent at 55% of all samples tested. This study was conducted to find potential antagonistic rhizobacteria isolated from various rhizospheres of plants grown in Bali. A total of 1,040 rhizobacteria isolates were tested for their antagonistic activity against the growth of C. scovillei on potato dextrose agar. Results showed that 10 isolates inhibited the growth of C. scovillei by more than 80%. Among these isolates C1 and C7B possessed inhibitory activity at 94.9% and 94.3%, respectively. Molecular identification based on analysis of 16S rRNA gene showed that isolate C1 belonged to the species Paenibacillus polymyxa, whereas isolate C7B was identified as Bacillus siamensis. According to scanning electron serious damage on mycelia of C. scovillei was observed. Wrinkles were observed on mycelia of C. scovillei grown jointly with rhizobacterial isolate C1, whereas no wrinkle was observed on C. scovillei grown solely. Three compounds were detected in the hexane phase of cell-free filtrate P. polymyxa C1, namely, 3-hydroxy-2-butanone and 2,3-butanediol. These compounds may be responsible for antifungal activity against C. scovillei.

The life cycle of Colletotrichum lindemuthianum fungus, susceptibility of Armenian bean varieties to anthracnose disease, as well as its development dynamics have been investigated in conditions of Lor community in Aremenia. Preventive measures have reduced the winter stock of pathogen infection and intensity of the disease development, while double application of Quadris and Revus Top fungicides during the vegetation period suppressed the development of anthracnose by 86.3-88.6 % and 91.6-92.4 %, respectively, as compared to the recorded indices in the control variant. Thus, the recommended fungicides can be used alternately to combat bean anthracnose.

Anthracnose disease on chili pepper has been known to seriously interfere with the plant growth and obviously reduce the yield. The disease is caused by Colletotrichum spp. In Bali, Indonesia, six species of Colletotrichum have been identified: Colletotrichum scovillei, C. acutatum, C. nymphaeae, C. gloeosporioides, C. truncatum, and C. fructicola. However, among them the C. scovillei was found to be the most prevalent cause of anthracnose on chili pepper in Bali. Two species of antagonist against C. scovillei, namely Paenibacillus polymyxa C1 and Bacillus siamensis C7B, have been identified. In this study the effectiveness of P. polymyxa C1 formulation was evaluated under greenhouse condition on chili pepper cultivars Cabe Besar. Application of formulation was conducted by a mini hand sprayer once to five times with a week interval. Results of the study showed that treatment with five applications significantly (p < 0.05) reduced the disease incidence, disease intensity, and the yield loss of chili pepper cultivar Cabe Besar. Alose relationship was observed between the number of applications with disease intensity, with coefficient of determination (R2) at 0.929. These results revealed that the formulation of P. polymyxa C1 effectively control the anthracnose disease on chili pepper, particularly on chili pepper cultivar Cabe Besar, and thus can be recommended for field testing to confirm its stability under field conditions.
