Drought stress response in Jatropha curcas: Growth and physiology

Aquaporin JcPIP2 is involved in drought responses in Jatropha curcas.

Water channel proteins, aquaporins, play fundamental roles in transmembrane water movements in plants. A new full-length cDNA encoding aquaporin was isolated from the seedlings of Jatropha curcas. The gene of the plasma membrane intrinsic protein (PIP) from J. curcas (JcPIP2) contained an 843 bp open reading frame encoding a protein of 280 amino acids. The amino acid sequence showed 94% identit...

Jatropha curcas L. Root Structure and Growth in Diverse Soils

Unlike most biofuel species, Jatropha curcas has promise for use in marginal lands, but it may serve an additional role by stabilizing soils. We evaluated the growth and structural responsiveness of young J. curcas plants to diverse soil conditions. Soils included a sand, a sandy-loam, and a clay-loam from eastern Mexico. Growth and structural parameters were analyzed for shoots and roots, alth...

Growth and antioxidant responses in Jatropha curcas cotyledons under lead stress.

Jatropha curcas embryos were grown in vitro to observe the effects of lead on cotyledon responses. The cotyledon biomass increased initially and then decreased with increasing lead concentration. The SOD activity increased gradually up to 200 microM and then decreased. The POD activity showed a similar trend. The CAT activity was increased at all lead concentrations, the highest activity being ...

Towards domestication of Jatropha curcas

91 10.4155/BFS.09.4 © 2010 Future Science Ltd Jatropha curcas L. (further referred to as Jatropha) is a rapidly emerging biofuel crop currently attracting a lot of interest and investments [1]. This stem-succulent [2] deciduous tree or shrub produces seeds rich in toxic oil (27–40% [3]). The oil can be extracted easily with techniques of different sophistication levels [4,5]. The crude Jatropha...
