“…Two new protein bands at molecular weight 47.2 KD and 16.3 KD were appeared in all infected plants treated with Bio-Zeid and Bio-Arc while, not appeared in the control plants. These results are in agreement with those reported by El-Askary et al (2003) and Akladious et al, (2015). They showed that new protein bands induced in infected plants treated with the bio-products act as a protein marker in resistance mechanisms; such response allows plants to become more tolerant to the pathogens.…”

This study evaluated the efficacy of two commercial biocides, i.e. Bio-Zeid (Trichoderma album) and Bio-Arc (Bacillus megaterium) against Fusarium wilt disease of tomato caused by Fusarium oxysporum f. sp. lycopersici (FOL) and F. solani (FS). Application of these biocides as soil treatment significantly (P=0.05) reduced the percentage of the disease severity of tomato wilt caused by both pathogens under greenhouse conditions at growing seasons 2016 and 2017 when compared to the control treatment. Untreated and treated infected tomato plants (Super strain B cv.) with the tested products were subjected to study the alterations in gene expression using protein profile and four different isozymes(esterase, peroxidase, chitinase and Superoxide Dismutase isozyme) systems. Treated tomato plants showed differences in protein and isozymes banding patterns compared to untreated plants. Two new protein bands at molecular weight 47.2 KD and 16.3 KD were appeared in all infected plants treated with Bio-Zeid and Bio-Arc while, not appeared in control plant. This indicates that these treatments were able to induced new protein bands which increase resistance in tomato plants to Fusarium wilt infection. All treatments were able to induced new protein bands patterns which increasing resistance to Fusarium wilt, but treatment with Bio-Arc was the best because it induced the higher numbers of new protein bands. At the same time, new esterase band (EST-5a), peroxidase (PRX-4a), chitinase (Chit-5b) and Superoxide Dismutase isozyme (SOD-1a) bands were detected in all treatments while not appeared in the control.

Canavanine (CAN) is a nonproteinogenic amino acid, and its toxicity comes from its utilization instead of arginine in many cellular processes. As presented in previous experiments, supplementation of tomato (Solanum lycopersicum L.) with CAN led to decreased nitric oxide (NO) level and induced secondary oxidative stress. CAN improved total antioxidant capacity in roots, with parallel inhibition of enzymatic antioxidants. The aim of this work was to determine how CAN-dependent limitation of NO emission and reactive oxygen species overproduction impact content, localization, and metabolism of phenolic compounds (PCs) in tomato roots. Tomato seedlings were fed with CAN (10 and 50 µM) for 24 or 72 h. Inhibition of root growth due to CAN supplementation correlated with increased concentration of total PCs; CAN (50 µM) led to the homogeneous accumulation of PCs all over the roots. CAN increased also flavonoids content in root tips. The activity of polyphenol oxidases and phenylalanine ammonia-lyase increased only after prolonged treatment with 50 µM CAN, while expressions of genes encoding these enzymes were modified variously, irrespectively of CAN dosage and duration of the culture. PCs act as the important elements of the cellular antioxidant system under oxidative stress induced by CAN.

“…Biological control is becoming increasingly important in integrated pest management programs, especially when discussing integrated production towards sustainable agriculture. Many plant and plant extracts have been reported to have antimicrobial properties against plant pathogenic fungi (Sharmin et al, 2013;Vergnes, 2014;Akladious et al, 2015;Santos et al, 2015). Allamanda species extract has been proved as effective in controlling plant pathogenic fungi (Islam, 2004;Ravikumar et al, 2013;Basar et al, 2011;Mone et al, 2013;Barros et al, 2015;Brito et al, 2018).…”

This research aims to analyze the effect of the extract from a native plant from Caatinga, Allamanda blanchetti, in the induction of resistance mechanisms in a sugarcane variety smut-susceptible. Initially, it carried out a phytochemical analysis to know the main plant compounds used in this study. Diverse chemicals content in ethanolic extract from A. blanchetii were detected by thin-layer chromatography (TLC). Flavonoids, were more abundant compounds following by terpenes, stereroids and saponins. Under greenhouse conditions the sugarcane plants, SP-791011 (smut-susceptible), were sprayed with extracts from A. blanchetti extracted at cold at concentrations of 1000 ppm and acilbenzolar-S-metil (ASM) (100 mg/L). Leaves were collected at 0, 24 and 48 hours after spraying and used in the RT-PCR analysis for to identify the defense gene expression. Change in gene expression were observed in the different treatments, especially in the expression of pathogenesis-related (PR) genes. The extract of A. blanchetti induced an increase in the glucanase expression and was more effective than ASM inducer. SNPR1 gene show increased in the two treatment. The results indicate that A. blanchetti extracts was able to activate the resistance mechanism as observed in resistant plants. This paper is the first report about the use of Caatinga natural plant extracts inducing resistance genes against Sporisorium scitamineum in sugarcane susceptible genotype.
