Polyamines are considered to participate in various processes of plant development. In this study, the possible implication of putrescine catabolism by the copper-containing amine oxidases (CuAOs, EC 1.4.3.6) in the development of roots and hypocotyls was examined. For this purpose, two cDNA clones of Glycine max (L.) Merr. cv. Williams, designated as GmCuAO1 and GmCuAO2, exhibiting extensive s...

Three growth inhibitors which might be involved in phototropism of Sakurajima radish (Raphanus sativus var. hortensis f. gigantissimus Makino) hypocotyls, were isolated as crystalline forms from light-exposed radish seedlings and identified as cis- and trans-raphanusanins and 6-methoxy-2,3,4,5-tetrahydro-1,3-oxazepin-2-one (designated raphanusamide). The cis- and trans-raphanusanins inhibited g...

The process of etiolation contributes significantly to vegetative propagation and root formation woody plants. However, the molecular interaction pattern different factors for etiolated adventitious development in plants remains unclear. In present study, we explored changes at stages Robinia pseudoacacia. Histological transcriptomic analyses were performed lower portion hypocotyls ascertain re...

Salinity in soil can affect Jatropha seedling metabolism, interfering with plant establishment. In this study, the effect of salinity on mobilization reserves during development seedlings was tested. Two genotypes were used and three concentrations NaCl applied between 4th 8th days after germination. The effects growth, terms fresh dry phytomass, ionic partition, sugar quantification, starch, p...

there are many methods for weed management one of them is putting allelopathic and cover crop in weed management programs. in order to study the effect of sowing time (delayed sowing, synchronic sowing) and wheat cultivars (shiraz, roshan, tabasi, niknejad) on allelopathic interaction of wheat and weed species (secale cereale l., avena ludoviciana l.: monocotyledon, convolvulus arvensis l. and ...
