Cytogenetic and protein quantification in polyploid somatic tissue of Myrmeleon uniformis (Neuroptera, Myrmeleontidae)
(2015-04-27)
Myrmeleon unifomis Malpighian tubules cells were analyzed under two aspects: chro-matin structure and total protein quantifcation in the three larval phases (L<inf>1</inf>, L<inf>2</inf> and L<inf>3</inf>) and in adults. ...
What can cell cycle and ultrastructure tell us about desiccation tolerance in Leucaena leucocephala germinating seeds?
(2016-06-01)
Desiccation tolerance (DT) is the ability to tolerate dehydration to levels below 0.1 g(H2O) g−1(dry mass) and subsequent rehydration without lethal damage. Here, it is proposed that Leucaena leucocephala, a tree species, ...
Cellular and molecular aspects of quinoa leaf senescence
(Elsevier Ireland, 2015-09)
During leaf senescence, degradation of chloroplasts precede to changes in nuclei and other cytoplasmic organelles, RuBisCO stability is progressively lost, grana lose their structure, plastidial DNA becomes distorted and ...
Study of the somaclonal variation produced by different methods of polyploidization in Asparagus officinalis L.
(Springer, 2015-06)
Polyploid plants have been induced in different Asparagus officinalis L. breeding programs in order to obtain plants with improved agronomical traits, such as large spear diameter or segregation ratios with a higher number ...
Ploidy-dependent changes in the epigenome of symbiotic cells correlate with specific patterns of gene expression
(National Academy of Sciences, 2017-04)
The formation of symbiotic nodule cells in Medicago truncatula is driven by successive endoreduplication cycles and transcriptional reprogramming in different temporal waves including the activation of more than 600 ...
