“…MvRL is also a chitin‐binding protein like MuBL and MuLL, but it is a mannose‐binding and ion‐dependent protein, unlike the M. urundeuva lectins, which indicates distinct mechanisms of carbohydrate recognition. Cellulase modulation by peptide molecules was also reported by Fayyaz‐ur‐Rehman et al ., who demonstrated that peptides isolated from aqueous extracts of Azadirachta indica and Buxus sempervirens leaves exerted an inhibitory effect on cellulases from the bug Planococcus citri . Those authors concluded that these leaves can be a source of peptides for the control of this insect.…”

“…On citrus, P. citri damages plants by feeding on roots, bark, foliage and fruit [2]. During feeding P. citri injects toxic saliva into plants and extracts phloem sap, and induces symptoms including defoliation, fruit discoloration and fruit drop [2]. In addition, P. citri secretes copious amounts of honeydew leading to the development of sooty mold which also leads to reduced fruit quality and lowered plant vigor through the loss of photosynthetic capacity.…”

The citrus mealybug, Planococcus citri, is an important plant pest with a very broad plant host range. P. citri is a phloem feeder and loss of plant vigor and stunting are characteristic symptoms induced on a range of host plants, but P. citri also reduces fruit quality and causes fruit drop leading to significant yield reductions. Better strategies for managing this pest are greatly needed. RNA interference (RNAi) is an emerging tool for functional genomics studies and is being investigated as a practical tool for highly targeted insect control. Here we investigated whether RNAi effects can be induced in P. citri and whether candidate mRNAs could be identified as possible targets for RNAi-based P. citri control. RNAi effects were induced in P. citri, as demonstrated by specific target reductions of P. citri actin, chitin synthase 1 and V-ATPase mRNAs after injection of the corresponding specific double-stranded RNA inducers. We also used recombinant Tobacco mosaic virus (TMV) to express these RNAi effectors in Nicotiana benthamiana plants. We found that P. citri showed lower fecundity and pronounced death of crawlers after feeding on recombinant TMV-infected plants. Taken together, our data show that actin, chitin synthase 1 and V-ATPase mRNAs are potential targets for RNAi against P. citri, and that recombinant TMV is an effective tool for evaluating candidate RNAi effectors in plants.

“…Hence, the WAO process catalyzed the high solubilization of the hemicellulose sugars from the solid fraction but was unable to result in cause a major hydrolysis of the solubilized hemicellulose molecules into monosaccharides [25]. The heavy metals were analyzed using ICP-OES indicated that Ag, Pb, Hg were not detected which could be inhibitory to the enzymes during enzymatic hydrolysis [26].…”

The present work explores the potential of wet air oxidation (WAO) for pretreatment of mixed lignocellulosic biomass to enhance enzymatic convertibility. Rice husk and wheat straw mixture (1:1 mass ratio) was used as a model mixed lignocellulosic biomass. Post-WAO treatment, cellulose recovery in the solid fraction was in the range of 86% to 99%, accompanied by a significant increase in enzymatic hydrolysis of cellulose present in the solid fraction. The highest enzymatic conversion efficiency, 63% (by weight), was achieved for the mixed biomass pretreated at 195°C, 5 bar, 10 minutes compared to only 19% in the untreated biomass. The pretreatment under the aforesaid condition also facilitated 52% lignin removal and 67% hemicellulose solubilization. A statistical design of experiments on WAO process conditions was conducted to understand the effect of process parameters on pretreatment, and the predicted responses were found to be in close agreement with the experimental data. Enzymatic hydrolysis experiments with WAO liquid fraction as diluent showed favorable results with sugar enhancement up to 10.4 g L -1 .
