“…Climatic conditions affect the crop cycle considering the direct interference in plant phenology, and therefore in the growth phases (Lazreg-Aref et al, 2017). Thus, based exclusively on the variables presented above, the obtained results suggest that the fig tree cv "Roxo de Valinhos" can be cultivated at the production level in domestic and commercial orchards under the soil and climatic conditions of Bom Jesus, Piauí.…”

The phenological adaptability and growth of the fig tree (Ficus carica L.) was observed periodically in the Brazilian semi-arid, State of Piauí, Brazil. The study was done using in 46 plants of the fig tree cv “Roxo de Valinhos”, in Bom Jesus, Piauí in the period from April to August of 2018. The meteorological elements associated with phenology were: air temperature, relative humidity, precipitation, and photoperiod. The results revealed significant relations between the phenology, growth, and climatic conditions showing promising answers for the cultivation of the fig tree cv “Roxo de Valinhos”, in the semi-arid region of Piauí.

“…The jelly fig latex collected was apparently reduced in the afternoon. In contrast, it was reported that the maximum F. carica latex was obtained upon fruit harvest in late afternoon 30 . The average yield of jelly fig achenes obtained was ~650 tonnes per year according to the Taiwan official annual report from 2017 to 2021.…”

BACKGROUND The achenes/seeds of endemic jelly fig (Ficus pumila var. awkeotsang) fruit have been applied to prepare a traditional beverage in Taiwan. Upon fruit harvest, jelly fig latex exuded from stalks was discarded. Protease activity was monitored in its latex. Proteases capable of hydrolyzing proteins have many application aspects based on diverse characteristics. Commercial plant proteases are frequently from latex. RESULTS The latex protease of jelly fig, termed FaFicin, was purified to homogeneity with a molecular mass of ~32 kDa on sodium dodecyl sulfate–polyacrylamide gel electrophoresis. According to liquid chromatographic–tandem mass spectrometric analyses, the expected protein band of protease was matched to ficin A, ficin B or chymopapain from common fig or papaya. Iodoacetamide, an inhibitor of cysteine protease, inhibited its protease activity completely. Hence FaFicin was identified as a papain‐like cysteine protease (PLCP), exhibiting more than 80% and 70% activity as assayed at pH 5–8 and 40–70 °C, respectively. It maintained ~89% of initial activity after 120 min at 55 °C and pH 7. Moreover, FaFicin could degrade the myosin and actin of meat, and clot milk. CONCLUSION The ficin FaFicin was obtained, purified and identified as a PLCP member from agricultural waste: jelly fig latex. It possessed activity under a wide range of pH values and temperature, and exhibited excellent thermostability. Based on its initial evaluation as a meat tenderizer and milk clotting reagent, the application of FaFicin was possible, which may extend utilization of jelly fig. © 2022 Society of Chemical Industry.
