“…"Quina" or "Cascarilla" are the most common names for Cinchona plants whose bark has medicinal properties. Each species has different concentrations of alkaloids [4] and may vary according to locality, altitude, soil type, age of the tree and time of harvest [1,5]. Therefore, the species of the Cinchona genus have been used as an effective medicine against malaria in the 17th century [6] since they possess a component called "quinine" [6].…”

The genus Cinchona belongs to the Rubiaceae family and comprises native Peruvian tree species distributed in tropical areas. It is currently endangered due to human disturbance and overexploitation for medicinal, forestry and food uses. To date, the current and future distribution of Cinchona spp. under the climate change scenario is unknown. Here, we modeled the present and future spatial distribution of the genus Cinchona using bioclimatic, edaphic and topographic variables using the maximum entropy algorithm (MaxEnt). The results indicate that 8.08% (103,547.89 km2) and 6.02% (77,163.81 km2) of the surface of Peru possesses areas with high and moderate distribution probabilities, respectively, to host the genus Cinchona, distributed mainly in the departments of Cusco, Amazonas, San Martín and Cajamarca. Furthermore, according to future climate scenarios, the areas of high suitability will increase their extension for the years 2050 and 2070 by 3.65% and 3.9%, respectively. Since Peru seeks to promote the forest sector to be the other force for its development, this study can be considered as a basis for the establishment of priority zones for the conservation, restoration, reforestation and sustainable management of Cinchona spp. species in Peru.

“…Moreover, in tomato [ 30 ], cucumber [ 31 ] and Mesona chinensis [ 32 ], positive responses of plant radial growth to RL were found. However, there are also reports indicating the positive role of BL on plant growth; for instance, BL enhanced the shoot length and bud numbers of in vitro-cultured Cinchona officinalis [ 19 ] and promoted hypocotyl elongation of arugula [ 33 ]. Similarly, the highest-level BL treatment showed the highest plant height, leaf number, total leaf area, and leaf biomass in Hydrocotyle bonariensis [ 34 ], with similar results apparent in eggplant treated by BL [ 35 ].…”

“…Red and blue lights are the main subjects of study due to their prominent roles in the regulation of plant life activities [ 12 ]. For example, red and blue lights affect plant height, biomass, stem diameter, and bud numbers in opposing directions [ 17 , 18 , 19 ]. Red and blue lights are the main light types that regulate stomatal movement, but this is subject to significant species-specific differences [ 20 , 21 ].…”

“…Light quality is a critical environmental factor in tissue culture. Recently, reports have studied the impact of various light spectra on the growth of plants in vitro in many species, including pitaya [ 17 ], potato [ 18 ], Cinchona officinalis [ 19 ], Leucojum aestivum [ 22 ], Swertia chirayita [ 23 ], Pyrus communis [ 24 ], Valencia orange [ 25 ] and banana [ 26 ]. However, to date, no such study has been conducted on in vitro-grown cassava plants.…”

Light quality is highly important for growth control of in vitro plant cultures. Here, we investigated the effect of blue light (BL), red light (RL) and combined red and blue light (RBL) on in vitro cassava growth. Our results indicate that RL facilitated radial elongation of cassava and increased stomatal conductance as well as glucose, sucrose, fructose and starch content in leaves and cellulose content in the stem. It also enhanced SOD and POD activities but decreased the stomatal density and chlorophyll and carotenoid content in leaves. In addition, RL leads to shorter palisade cells, denser chloroplasts and more starch granules. These phenotypic changes were inverted following BL treatment. The expression levels of photosynthesis-related genes MeLHCA1, MeLHCA3, MePSB27-2, MePSBY, MePETE1 and MePNSL2 in leaves were at their lowest following RL treatment, while the expression levels of MePSB27-2, MePSBY, MePETE1 and MePNSL2 were at their highest after BL treatment. The phenotypic changes after RBL treatment were between the values observed for the RL and BL treatments alone. Moreover, the responses of SC8 and SC9 cassava varieties to light quality were largely conserved. As such, we believe that the results of this study lay the foundation for controlling the in vitro growth of cassava seedlings by light quality.
