Iron is essential for plants. However, excess iron toxic, leading to oxidative stress and decreased productivity. Therefore, plants must use finely tuned mechanisms keep homeostasis in each of their organs, tissues, cells organelles. A few the genes involved have been identified recently, we used some protein sequences as queries look corresponding rice (Oryza sativa) genome. We assigned possible functions thirty-nine new genes. Together with four previously reported sequences, analyzed a...
Adventitious rooting is essential for vegetative propagation of woody species. We studied the effects auxin and light on development adventitious roots in cuttings obtained from seedlings Eucalyptus saligna Smith E. globulus Labill an attempt to characterize process identify factors controlling rhizogenesis. Root was scored as percentage, root density (roots per rooted cutting), mean time length. In both species, reduced presence auxin. Cuttings 2-month-old were responsive lower...
Abstract Cell culture of Taxus cuspidata represents an alternative to whole plant extraction as a source taxol and related taxanes. Feeding phenylalanine callus cultures was previously shown result in increased yields, probably due the involvement this amino acid precursor for N ‐benzoylphenylisoserine side chain taxol. Inthis study, we have examined effect various concentrations phenylalanine, benzoic acid, ‐benzoylglycine, serine, glycine, alanine, 3‐amino‐3‐phenyl‐propionic on...
We characterized the adventitious rooting response of Eucalyptus globulus Labill. to various concentrations calcium, nitrogen, phosphorus, iron, manganese, zinc, boron and copper. The parameters analyzed were percent rooting, root number, length mean time. Root number significantly affected by mineral nutrition, whereas time percentage seemed be closely related auxin availability. was nitrogen source influenced iron source. Based on these results, we evaluated combinations several minerals...
Abstract Plants of the genus P inus are able to grow in a wide range environments, many which quite harsh and extreme. High benefit–cost ratio pine plantations resides on relatively low demand for management investments high economic environmental services returns. Pine forests work as sinks atmospheric carbon, contributing greenhouse effect mitigation. They important sources numerous useful products, including not only wood cellulose but also nonwood products used by chemical, food,...
Abstract Background Eucalyptus globulus and its hybrids are very important for the cellulose paper industry mainly due to their low lignin content frost resistance. However, rooting of cuttings this species is recalcitrant exogenous auxin application often necessary good root development. To date one most accurate methods available gene expression analysis quantitative reverse transcription-polymerase chain reaction (qPCR); however, reliable use technique requires reference genes...
Abstract The literature describes different rooting protocols for Arabidopsis thaliana as models to study adventitious rooting, and results are generally perceived comparable. However, there is a lack of investigations focusing on the distinct features, advantages limitations each method in with both wild‐type (WT) ecotypes their respective mutants. This investigation was undertaken evaluate process three experimental systems, all using A. , analysing same parameters after transient exposure...
