miR-71b regulation of insulin/IGF-1 signaling during starvation in planarians

Y. Y. Wu, Zhao, J. M., Liu, Q., Guo, Q., Liu, Z., Wang, X. X., Wang, C. Y., Li, R. Y., Zhang, Y. Z., and Zhang, S. T., miR-71b regulation of insulin/IGF-1 signaling during starvation in planarians, vol. 14, pp. 11905-11914, 2015.

Planarians, which have a large population of stem cells called neoblasts, are molecularly tractable model systems used in the study of regeneration. However, planarians have strong resistance to hunger and have developed growth arrest strategies. For example, they can change their size and undergo growth regression during starvation periods. The results of the current study show that the microRNA, miR-71b, and the insulin/IGF-1 signaling pathway have important functions in the development of starvation-induced planarians.

Agrobacterium-mediated transformation of tomato (Solanum lycopersicum L.) using the expansin 10 (CsEXP10) gene

Y. D. Sun, Luo, W. R., Sun, S. Y., and Ni, L., Agrobacterium-mediated transformation of tomato (Solanum lycopersicum L.) using the expansin 10 (CsEXP10) gene, vol. 14, pp. 16215-16221, 2015.

The cucumber expansin 10 (CsEXP10) gene was previously cloned from young cucumber fruits but its role has not been defined. To determine the role of this gene in plant growth and development, a CsEXP10 gene transformation system was established. The open reading frame of the gene was inserted behind the CaMV35S promoter of vector pCAMBIA1301, and the construct was introduced into tomato plants by Agrobacterium-mediated transformation.

Genetic stability of micropropagated plants of Crambe abyssinica Hochst using ISSR markers

E. T. Werner, Soares, T. C. B., Gontijo, A. B. P. L., Neto, J. D. Souza, and Amaral, J. A. Tdo, Genetic stability of micropropagated plants of Crambe abyssinica Hochst using ISSR markers, vol. 14, pp. 16450-16460, 2015.

Crambe (Crambe abyssinica) is a non-edible annual herb, which was first cultivated to extract oil for industry, and now has great potential for biodiesel production. The objective of this investigation was to evaluate the genetic stability of micropropagated plants of the C. abyssinica Hochst cultivar ‘FMS brilhante’ using polymerase chain reaction techniques based on inter-simple sequence repeat (ISSR) molecular markers.
