    Carotenoids: New Applications of “Old” Pigments

    Stefan M. Kolašinac1, Zora P. Dajić Stevanović1,*, Sofija N. Kilibarda1,  Aleksandar Ž. Kostić2,*

    Phyton-International Journal of Experimental Botany, Vol.90, No.4, pp. 1041-1062, 2021, DOI:10.32604/phyton.2021.015996

    Abstract Carotenoids represent a large group of mainly red, orange, and yellow natural metabolites mainly involved in regulation of many metabolic processes. Carotenoids are beneficial for human health. Current study describes the importance, chemical composition and functioning of carotenoids. It is well known that carotenoids support pigments acting in light absorbance mechanisms during photosynthesis, and are known to protect the chlorophyll molecules from oxidative stress and reactive oxygen species (ROS) damage. Carotenoids are involved in signaling processes in plants, responses to environmental stresses, pollination, germination and reproduction, and development regulation. As nutrients of strong antioxidant activity… More >

    An Efficient Ciphertext-Policy Attribute-Based Encryption Scheme with Policy Update

    Changji Wang1, *, Yuan Yuan2

    CMC-Computers, Materials & Continua, Vol.63, No.2, pp. 1031-1041, 2020, DOI:10.32604/cmc.2020.06278

    Abstract Ciphertext-policy attribute-based encryption (CP-ABE) is a promising cryptographic solution to the problem for enforcing fine-grained access control over encrypted data in the cloud. However, when applying CP-ABE to data outsourcing scenarios, we have to address the challenging issue of policy updates because access control elements, such as users, attributes, and access rules may change frequently. In this paper, we propose a notion of access policy updatable ciphertext-policy attribute-based encryption (APU-CP-ABE) by combining the idea of ciphertext-policy attribute-based key encapsulation and symmetric proxy re-encryption. When an access policy update occurs, data owner is no longer required… More >

    Phyton-International Journal of Experimental Botany, Vol.85, pp. 1-6, 2016, DOI:10.32604/phyton.2016.85.001

    Abstract Antagonistic bacteria used as biological control agent may loss effectiveness at the field due to environmental factors such as UV radiation, dryness and high temperature. An inexpensive alternative to protect antagonistic bacteria against such factors is the use of microencapsulating agents. In this work, the effect of microencapsulation of Bacillus subtilis with commercial gums on their antagonistic capacity against Meloidogyne incognita was evaluated. The efficiency of the microencapsulation was verified by the difference between the initial and final concentrations of protein release. The effectiveness as antagonist was evaluated against M. incognita in tomato under greenhouse More >
