Proline accumulation is involved in plant osmotic stress tolerance. Given that DNA methylation is related to almost all metabolic processes through regulation of gene expression, we suspected that this epigenetic modification and proline biosynthesis are probably related. To test this, we investigated whether osmotic stress-induced proline accumulation is associated with DNA methylation modific...

Mobilization of N from leaves of barley (Hordeum vulgare L.) during water stress, and the role of proline as a mobilized species, were examined in plants at the three-leaf stage. The plants responded to water stress by withdrawing about 25% of the total reduced N from the leaf blades via phloem translocation. Most of this N loss was during the first 2 days while translocation of (14)C-photosynt...

Two isomers of hydroxyproline are present in sandal leaves (Santalum album L.), cis-4-hydroxy-Lproline in the free state (Radhakrishnan & Giri, 1954) and bound trans-4-hydroxy-L-proline, which forms a minor proportion (4%) of total hydroxyproline (Kuttan & Radhakrishnan, 1969). Bound trans-4-hydroxy-L-proline in plants (Lamport, 1965) is presumably synthesized by a mechanism similar to that in ...

Abstract Salinity is one of abiotic stress that affects plant growth and production. The objective this study was to investigate the effect salinity vermicompost on morphology physiology parameters Calliandra haematocephala. experiment carried out with treatments at 1000, 2000 3000 ppm in addition control (tap water, 280 ppm), 5%, 10%, 15%, 20% control. results indicated increasing level result...
