“…It is necessary to conduct studies to determine the effect of Acinetobacter sp on some metabolic pathways in potato seedlings which may have influence on tuber production [62] , [63] , [64] , [65] . The results obtained in the present work are similar to those reported by Frommel et al [66] , Nowak et al [67] and Sturz [68] .…”

One of the most serious diseases in potato cultivars is caused by the pathogen Phytophthora infestans, which affects leaves, stems and tubers. Metalaxyl is a fungicide that protects potato plants from Phytophthora infestans. In Mexico, farmers apply metalaxyl 35 times during the cycle of potato production and the last application is typically 15 days before harvest. There are no records related to the presence of metalaxyl in potato tubers in Mexico. In the present study, we evaluated the effect of Acinetobacter sp on metalaxyl degradation in potato seedlings. The effect of bacteria and metalaxyl on the growth of potato seedlings was also evaluated. A metabolite profile analysis was conducted to determine potential molecular biomarkers produced by potato seedlings in the presence of Acinetobacter sp and metalaxyl. Metalaxyl did not affect the growth of potato seedlings. However, Acinetobacter sp strongly affected the growth of inoculated seedlings, as confirmed by plant length and plant fresh weights which were lower in inoculated potato seedlings (40% and 27%, respectively) compared to the controls. Acinetobacter sp also affected root formation. Inoculated potato seedlings showed a decrease in root formation compared to the controls. LC-MS/MS analysis of metalaxyl residues in potato seedlings suggests that Acinetobacter sp did not degrade metalaxyl. GC–TOF–MS platform was used in metabolic profiling studies. Statistical data analysis and metabolic pathway analysis allowed suggesting the alteration of metabolic pathways by both Acinetobacter sp infection and metalaxyl treatment. Several hundred metabolites were detected, 137 metabolites were identified and 15 metabolic markers were suggested based on statistical change significance found with PLS-DA analysis. These results are important for better understanding the interactions of putative endophytic bacteria and pesticides on plants and their possible effects on plant metabolism.

“…Other crops were already tested as for the use of bacteria to improve plant behavior in order to obtain better yields under conditions adverse to plant development. For example, Nowak et al (1999) studied the effects of bacteria on potato transplanting. The authors verified that plants inoculated with bacteria behaved better in years with low rainfalls, but this did not occur in years with severe drought or heavy rains.…”

“…the ability to adapt to changing environmental conditions) [73,74]. Documented benefits of plant-microbe symbiosis include greater growth rates (shoots and roots) [71,75,76] and host's overall surface area [77], greater proliferation of root hairs (i.e., root branching and improved root-soil contact for greater nutrient and water uptake) [78,79] and increased resistance to biotic and abiotic stresses [65,76] (e.g., transplantation, drought, and heat) [80][81][82]. Larger bacterial communities predominately result in greater plant growth promotion [65,83].…”

Through the development of superior plant varieties that benefit from high agrochemical inputs and irrigation, the agricultural Green Revolution has doubled crop yields, yet introduced unintended impacts on environment. An expected 50% growth in world population during the 21st century demands novel integration of advanced technologies and low-input production systems based on soil and plant biology, targeting precision delivery of inputs synchronized with growth stages of crop plants. Further, successful systems will integrate subsurface water, air and nutrient delivery, real-time soil parameter data and computer-based decision-making to mitigate plant stress and actively manipulate microbial rhizosphere communities that stimulate productivity. Such an approach will ensure food security and mitigate impacts of climate change.
