The aim of the present study was to scrutinize the response of banana (Grand Naine variety) plants when interacting with dead or live pathogen, Fusarium oxysporum f.sp. cubense, a causative agent of Panama disease. Response of plants was evaluated in terms of induction of defense-related marker enzyme activity, namely, peroxidase (POX), polyphenol oxidase (PPO), β-1,3 glucanase, chitinase, and phenolics. Plant's interaction with live pathogen resulted in early induction of defense to restrain penetration as well as antimicrobial productions. However, pathogen overcame the defense of plant and caused disease. Interaction with dead pathogen resulted in escalating defense response in plants. Later on plants inoculated with dead pathogen showed resistance to even forced inoculation of live pathogen. Results obtained in the present study suggest that dead pathogen was able to mount defense response in plants and provide resistance to Panama disease upon subsequent exposure. Therefore, preparation from dead pathogen could be a potential candidate as a biocontrol agent or plant vaccine to combat Panama disease.

Species belonging to the genus of Pseudomonas are known to possess metabolic versatility and are capable of adapting to various environments. One such strain BG, possessing urease activity, was isolated from marine water from the Gulf of Khambhat, Gujarat. 16S rRNA gene sequence analysis was performed to identify the isolate, which showed that it was the closest neighbor to be Pseudomonas aeruginosa strain BS8. Strain BG was accessed (meant to be assessed?) for multiple plant growth promoting and biocontrol traits. It tested positive for indole-3-acetic acid (IAA) production with 19 mg ml -1 of IAA yield, phosphate solubilization with 13 mg ml -1 solubilization of tri-calcium-phosphate and it showed maximum of 27 mg ml -1 of ammonia production. Further, BG isolate could produce hydrocyanic acid, siderophore, catalase and showed growth inhibition of Aspergillus flavus and Fusarium oxysporum f. sp. cubense confirming its potential antifungal activity. The marine isolate also showed 17.92 ± 1.79 unit min -1 ml -1 urease activity, and further, the presence of genes responsible for urease enzyme in strain BG was identified by amplification using gene specific primers. Talc based biofertilizer using strain BG was prepared and tested on seedling growth of Chickpea, where biofertilizer treated seeds showed enhanced growth. Thus, it was concluded that marine P. aeruginosa BG showed plant growth promotion and biocontrol abilities along with urease activity.

“…In literature, banana's quality assessment differs considering the factors that are investigated, but most studies focused on the Cavendish variety, which has become a standard on the global market because of its bigger and heavier bunches (Ding et al, 2007) and better resistance to physiopathology (Thakker et al, 2011). Considering the type of attributes that are investigated, peel colour may not necessarily indicate the quality or ripening stage of product since pulp and peel differ in their rate of ripening with respect to temperature (Nyanjage et al, 2001)., Thus, different quality attributes must be determined inaddition to colour, such as, nutraceutic, and texture, which are also influential to consumer's decision and shelf life (Tsamo et al, 2014).…”

The Multiple Factor Analysis (MFA) was applied to assess deterioration patterns and evaluate quality stability of bananas samples with 5 different origins. Quality evaluation (weight loss, dry matter, colour, total soluble solids, texture and nutraceutical analysis) was conducted at 21°C for up to 12 days of storage time. Ecuador samples retained a better colour and firmer texture during shelf life while Cameroon samples demonstrated very poor quality for almost all quality indicators. Although MFA showed a similar shelf life pattern for all banana samples, it was possible to observe a greater quality retention of Ecuador samples, represented by higher score values at dimension 1 than other samples. Even though there were significant differences of nutraceutical values during shelf life, the MFA contribution plot demonstrated that nutraceutical quality was not a good indicator of deterioration among the samples, especially with texture and colour parameters.
