“…8). The observed increase due to Enterobacter is a sign of immune stimulation since chlorogenate is considered a storage of caffeate and an intermediate of lignin biosynthesis (Rutherford et al 2013). Both Azospirillum brasilense and Bacillus sp.-induced chlorogenic and rutin accumulation in neotropical trees under drought stress (Tiepo et al 2020).…”

Plant Growth Promoting Bacteria have proven themselves in agricultural applications not only as biofertilizers but also as biocontrol agents against different phytopathogens. In this study, we focused on investigating the ability of Enterobacter cloacae to induce the immune response of Zea mays against Fusarium oxysporum infection. The bacterium was transformed with a plasmid to express Green Fluorescence Protein and used in a greenhouse experiment in combination with Fusarium infection in different treatments. E. cloacae successfully colonized the root, resulting in enhanced physical growth with great investment in leaf area, photosynthetic pigment production, and reduced anthocyanin content. E. cloacae left a considerable resistance to root rot caused by Fusarium, as the disease severity was reduced from 74.2% (in the case of Fusarium infection alone) to about 35.8% (in the case of E. cloacae addition 14 days before fungal infection). The amount of salicylic acid (SA) was markedly elevated, and Pathogen-Related Protein showed up to an eightfold increase in the expression level. From these results, we suppose that E. cloacae induces SA-dependent systemic acquired resistance, which allows pre-colonized plants to resist Fusarium infection.

“…This care is very important because, before the optimal point of maturation, in addition to the imbalance between the sugar and acid contents, it has already been shown that important nutrients are sequestered (for example, bound to tannins). That is why they remain in the milling bagasse (Rutherford, 2013).…”

Cachaça - the drink obtained by the distillation of fermented must from sugar cane juice – has been manufactured on an artisanal scale by thousands of Brazilian producers since the 16th century. However, in the 1970s, the survival of these producers was seriously threatened, due to the emergence of and competition from industrial cachaça, produced in significantly larger volumes and sold at very low prices. To help them face the situation, a robust project was designed to support small producers, integrating actions from government institutions, universities and producer associations. Since then, cachaça of rural origin has risen in the market as a reference for quality, richness and sensorial diversity – reaching high level of recognition and appreciation. Recently, Brazilian legislation authorized the name “alembic cachaça”, which was conditioned exclusively to batch distillation in copper stills. However, the technological advances introduced go beyond the distillation process, and characterize marked differences in relation to industrial cachaça. The objective of this article is to highlight the paradigms of good production practices for still cachaça – with emphasis on the fact that the origin can be attested using chemical markers.

“…The sugarcane borer, Datraea sacharalis , is one of the most serious pests, destroying the plant by invading the young stem portion of the sugarcane [ 10 ]. Epicuticular wax may act as a barrier, influencing the behavior and survival of larvae, and this can partially explain the differences between the sugarcane varieties in insect resistance [ 11 ]. Furthermore, some wax metabolites, such as alcohols and short-length chain aldehydes, have resistance to stalk borers [ 12 , 13 ].…”

Sugarcane wax has the potential to be utilized as a novel natural insecticide, which could help to reduce the large yield losses caused by agricultural pests. By employing the gas chromatography–mass spectrometry (GC-MS) approach, we conducted a study to analyze the composition of epicuticular wax from the rind of the sugarcane variety YT71210. A total of 157 metabolites, categorized into 15 classes, were identified, with naphthalene, a metabolite with insect-resistant properties, being the most prevalent. The feeding trial experiment suggested that sugarcane wax is toxic to silkworms by impacting the internal organs. Intestinal microbial diversity analysis suggested that the abundance of Enterococcus genus was significantly increased in both ordure and gut of silkworm after wax treatment. The results indicated that the feeding of wax has an adverse effect on the gut microbial composition of silkworms. Our findings lay a foundation for the efficacy of sugarcane waxes as a valuable natural insecticide and for the prediction of promising sugarcane varieties with insect resistance.
