Research ArticleOpen accessEvery word in the titleDifferences in the Response of Diploid and Tetraploid Anthurium andraeanum Seedling Roots to Salt StressYun Zhang, Yongping Zhang, Yongxu Qiao et al.To investigate the effects of salt stress on the growth, development, and endogenous hormone content of roots in diploid and tetraploid seedlings of Anthurium andraeanum, the enhanced salt tolerance was elucidated. The seedlings of A. andraeanum 'Pink champion' were placed at NaCl concentrations of 0, 50, 100, 150, and 200 mmol·L⁻¹. The results indicated that NaCl stress can reduce leaf … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 29 Jan 2026 · 1,776 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleMolecular Characterization of Banana (AA) Diploids with Contrasting Levels of Black and Yellow Sigatoka ResistanceClaudia Fortes Ferreira, Sebastiao Oliveira Silva, Nivia Paula Damasceno Sobrinho et al.Most banana cultivars are susceptible to many diseases, whereas Sigatoka leads to greatest yield losses. One of the strategies to overcome this disease is thorough banana genetic breeding which consists in the obtainment of improved (AA) diploids which are then crossed with triploids obtaining (AAAB) tetraploid disease resistant bananas also presenting other important agronomic characteristics. The prior knowledge of the … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,652 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProteins polymorphism of some populations of Lygeum spartum L. in AlgeriaAbderrezak Djabeur, Meriem Kaid-Harche, Douadi KhelifiLygeum spartum L. represent a natural barrier in the Algerian high plateaus against the advances of sand and turning into a desert. This species has two levels of ploïdy (diploïd cytotype 2n = 16 and polyploidy cytotype 2n = 40). Protein profile of several populations of this species have inter and intra specific variability. The polymorphic bands observed in the … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,093 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGeneration of Five New Musa Hybrids With Resistance To Black Sigatoka and High YieldRicardo Hernández, Teresa Ramírez, Juan Carlos Noa-Carrazana et al.The ability to identify genetic variation is indispensable to effective management and use of genetic resources. This work is the first approach concerning to generation and genetic differentiation of new Musa hybrid lines obtained in INIVIT (Cuba), crossing Musa acuminata male diploid (AA) x female triploid (ABB), genotypes selected by their resistant character to pests and diseases. From the obtained … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 8,811 accessesView PDF Cite
