After harvest,cassava(Manihot esculenta Crantz)storage roots undergo rapid postharvest physiological deterioration,producing blue-brown discoloration in the vasculature due to the production of polyphenolics(mainly quinonesand coumarins)by enzymes such as polyphenol oxidase(PPO).Here,we report the application of hen egg-white lysozyme(HEWL),a natural PPO inhibitor,in transgenic cassava to repress the symptoms of postharvest physiological *** HEWL-expressing transgenic plants had lower levels of the two main cassava coumarins tested,scopoletin and scopolin,compared with wild ***-expressing cassava also showed increased tolerance of oxidative ***,the lysozyme-PPO system proved to be functional in plants for repressing PPO-mediated commercial product browning.

This study presents a systematic review of the literature pertaining to dye-sensitized solar cells(DSSCs), in order to anticipate the direction and speed of change in technology trend. To study the general progression in DSSC research, we have assessed the evolution in annual DSSCs publications and their citations. Further, in order to identify the intellectual bases, we have also classified the journals, authors, institutes, and countries according to their scientific productivity in the field of DSSCs research during the period of 2007–2017.

Urban tree inventory is a great tool for gathering data that can be used by different end users. This study attempted to chart the species diversity in planted areas and measure their tree diameter at breast height to screen them for the carbon storage potential. A total of 2860 trees belonging to 36 species were recorded in the planted vegetation in parks and avenue plantation. The dominant species were Azadirachta indicia (25.5%), Conocarpus erectus (19.2%), Ficus spp. (15.5%), Tabebuia rosea (9.2%), Peitophorum pterocarpum (9.0%) and the remaining represents (21.6%) of the tree identified in this study. It was found that the highest contribution of carbon sequestration (CO2 equivalent) is dominated by the Ficus spp. (30.3%) with a total of 3399.3 tCO2eq, followed by Azadirachta indicia (25.4%) with a total of 2845.2 tCO2eq and Conocarpus erectus (20.4%) with a total of 2286 tCO2eq. The entire area has the capability to sequester around 11,213.3 tCO2eq and on average of 3.9 ± 0.1 tCO2eq. In accordance with the findings, it is imperative for the preservation of a sustainable environment to have vegetation that has the capacity to store carbon. The study suggests, there is potential to increase carbon sequestration in urban cities through plantation programs on existing and new land uses and along roads.
