Fall 2009
Identification of salt- resistant tree species and genotypes is needed for rehabilitation of lands affected by salinity in Mexico. This dissertation consists of four studies for analyzing the responses of Pinus leiophylla seedlings to salt. In the first study, resistance to salt stress was...

Over-expression of PIP2;5 aquaporin in a Populus tremula×P.alba clone and its effects on plant responses to low root temperature and osmotic stress
DownloadFall 2015
This dissertation describes the studies that examined: 1. Production of transgenic poplar over-expressing the poplar aquaporin PIP2;5 and 2. Comparison of the physiological properties of a transgenic poplar with the wild-type under different stress conditions including a) short-term low root...

Physiological responses of glycophytic and halophytic grasses Poa pratensis, Poa juncifolia, and Puccinellia nuttalliana to salt stress
DownloadFall 2017
Responses of two halophytic grasses Puccinellia nuttalliana and Poa juncifolia to treatments with NaCl were compared with the glycophytic grass Poa pratensis to better understand salt tolerance mechanisms in these plants. The experiments were carried out under controlled-environment conditions...

Root oxygen deprivation (root hypoxia) in flooding-prone areas is detrimental to most terrestrial plants and results in growth reductions and mortality. Although plants widely vary in their waterlogging tolerance, our understanding of these variations is limited to the ability of some plants to...
