“…Polyamines and especially the thylakoid-associated polyamines play a decisive role in protecting photosynthetic apparatus against oxidative stress. He et al (2008) found that Put induced the changes of endogenous polyamines in the photosynthetic apparatus to some extent, might be involved in the reduction of H 2 O 2 contents and membrane lipid peroxidation under salt stress. This result is supported by our experiments that Put reduced the number of plastoglobuli resulting from gradual thylakoid membrane degradation induced by salinity (Unpublished data).…”

“…When the same gene was transformed into sweet potato (Ipomoea batatas), the transgenic plants demonstrated more tolerance to salt and drought than the wild type (Kasukabe et al 2006). He et al (2008) reported changes in enzymatic and nonenzymatic antioxidant capacity of the SPDS over expressing transgenic Pyrus communis in response to NaCl stress. Compared to wild type, the transgenic lines had higher activities of antioxidant enzymes, less H 2 O 2 and MDA content.…”

Polyamines (PAs) are aliphatic polycations that are widespread in living organisms. In this review, we are focusing the correlation between endogenous PA titers and physiological perturbations and on the protective role of various analogues of PAs against abiotic stresses. PAs are involved in many physiological processes, such as cell growth and development and also respond to diverse abiotic stresses. Polyamines level shifts in different ways depending on several factors, such as plant species, tolerance or sensitivity to stress, and duration of stress. Exogenously supplied PAs protected plants from abiotic stress, whereas transgenic plants overexpressing PA biosynthetic genes exhibited stress tolerance. On the other hand, loss-of-function mutant of PA biosynthetic genes, or decrease of PA titers, resulted to decrease stress tolerance.

“…An ADC2 knockout mutant ( adc2 -1 ) was more sensitive to salt stress, which was reversed by exogenous Put (Urano et al 2004 ). In the same way, Arabidopsis He et al ( 2008 ) acl5 / spms mutant, defective for Spm production, is more sensitive to drought and salt stress, and Put application reverses the sensitivity to the defi ned abiotic stresses . Heterologous overexpression of PA genes, ADC/ODC/SAMDC/SPDS, which leads to accumulation of higher PA levels in transgenic plants, was found to make the transformed plants-Arabidopsis , rice, tobacco, and tomato-tolerant to abiotic stresses (Minocha and Sun 1997 ;Thu-Hang et al 2002 ;Kasukabe et al 2004 ;Wen et al 2008 ).…”

Agricultural production and quality are adversely affected by various abiotic stresses including water defi cit conditions (drought), salinity, extreme temperatures (heat, cold), light intensities beyond those saturating for photosynthesis, and radiation (UV B,C ). This is exacerbated when such exposure occurs during seed germination and reproductive phases of development. Estimates of crop losses can amount to billions of US dollars worldwide. To prevent such losses, it is necessary to develop stress-tolerant crops. One approach is to identify resistant germplasm using breeding strategies assisted by molecular markers and transfer those attributes to sensitive varieties, but this approach is a timely process. Introduction of genes that can improve stress tolerance in crops against heat, drought, and salinity is relatively a more effective technology. In this regard, the scientifi c community is well placed since a number of critical genes, particularly transcription factors that regulate gene expression in response to environmental stresses, have been identifi ed and the proof-of-the-concept validated. Translation of the technology into major crops (rice, wheat, sorghum, and maize) and vegetable/fruit crops is the need of the times.
