Panicle exsertion (PE) is an important morphological trait that is closely associated with spikelet fertility and grain yield. To understand the genetic basis of PE and its relationships with yield and yield-related traits, a recombinant inbred population consisting of 240 lines derived from a cross between an Indica cultivar ‘Kasalath’ and a Japonica germplasm ‘TD70’, was studied over two years.

Expression of LTP genes in response to saline stress in rice seedlings

G. P. Moraes, Benitez, L. C., Amaral, M. Ndo, Vighi, I. L., Auler, P. A., da Maia, L. C., Bianchi, V. J., and Braga, E. J. B., “Expression of LTP genes in response to saline stress in rice seedlings”, vol. 14, pp. 8294-8305, 2015.

Saline stress is one of the primary factors limiting increased rice productivity in the southern region of Brazil. Farming can be affected by salinity that is due to both the origin of the soils as well as the irrigation water. Lipid transfer proteins (LTPs) have many physiological functions, including in the response to saline stress. Therefore, the objective of this study was to quantify the relative expression of 11 genetic isoforms that encode LTP1-type proteins in rice genotypes tolerant and sensitive to saline stress in the vegetative period.
