Identification of microsatellite markers in coffee associated with resistance to Meloidogyne exigua
Authors: T.B. Pereira, T.A. Setotaw, D.N. Santos, A.N.G. Mendes, S.M.L. Salgado, G.R. Carvalho and R.M. Rezende
Meloidogyne species are destructive phytonematodes that result in reduced yields of coffee. The classic test for resistance to Meloidogyne exigua in coffee progenies is both expensive and time-consuming. The use of molecular marker techniques can assist the selection process when it is difficult to measure the phenotype, such as in cases of resistance to .. Read More»

Morphoagronomic characterization and genetic diversity of a common bean RIL mapping population derived from the cross Rud�¡ x AND 277
Authors: L.C. Silva, R.O. Batista, R.S.R. Anjos, M.H. Souza, P.C.S. Carneiro, T.L.P.O. Souza, E.G. Barros and J.E.S. Carneiro
Recombinant inbred lines (RILs) are a valuable resource for building genetic linkage maps. The presence of genetic variability in the RILs is essential for detecting associations between molecular markers and loci controlling agronomic traits of interest. The main goal of this study was to quantify the genetic diversity of a common beanRIL population deri.. Read More»

Analysis of genetic diversity and population structure in a tomato (Solanum lycopersicum L.) germplasm collection based on single nucleotide polymorphism markers
Authors: T. Wang, Q.D. Zou, S.Y. Qi, X.F. Wang, Y.Y. Wu, N. Liu, Y.M. Zhang, Z.J. Zhang and H.T. Li
Knowledge of genetic diversity is important to assist breeders in the selection of parental materials and in the design of breeding programs. In this study, we genotyped 348 inbred tomato lines, representing vintage and contemporary fresh-market varieties, by using 52 single nucleotide polymorphisms (SNPs); 45 of these were found to be polymorphic. The av.. Read More»

Isolation and characterization of the papaya MADS-box E-class genes, CpMADS1 and CpMADS3, and a TM6 lineage gene CpMADS2
Authors: M.-J. Lee, W.-J. Yang, C.-T. Chiu, J.-J. Chen, F.-C. Chen and L.-S. Chang
Papaya (Carica papaya L.) plants are polygamous, with female, male, and hermaphroditic flowers. To understand the roles of MADS-box genes in flower development and sex determination, we cloned cDNAs of E-class genes CpMADS1 and CpMADS3 and a TM6 lineage of the B-class gene CpMADS2 from young..

Genome-wide comparison of AP2/ERF superfamily genes between Gossypium arboreum and G. raimondii
Authors: Z.P. Lei, D.H. He, H.Y. Xing, B.S. Tang and B.X. Lu
The APETALA2/ethylene response factor (AP2/ERF) transcription factor superfamily is known to regulate diverse processes of plant development and stress responses. We conducted a genome-wide analysis of the AP2/ERF gene in Gossypium arboreum and G. raimondii. Using RPSBLAST and HMMsearch, a total of 271 and 269 AP2/ERF genes were identified in the G. arbor..

Photosynthesis enhanced oxidative stress tolerance in high-yield rice varieties (Oryza sativa var. japonica L.) in the field
Authors: X.D. Wei, L. Jin and X. Li
The objective of this study was to understand varietal differences in photosynthetic characteristics, chlorophyll fluorescence, antioxidant capability, and yield of japonica rice varieties. Nanjing 44, Oryza sativa var. japonica (average yield of 12.7 t/ha), Nanjing 46, and Nanjing 5055 (average yields of 11.3 and 11.5 t/ha) were included as “super&.. Read More»

Evaluation of genetic variability in in vitro sodium azide-induced Dendrobium �Earsakul� mutants
Authors: A. Wannajindaporn, O. Poolsawat, W. Chaowiset and P.A. Tantasawat
In vitro mutagenesis of Dendrobium ‘Earsakul’ was carried out by incubating the protocorm-like bodies in 0-5 mM sodium azide for 1 h. Twenty-eight putative mutants were evaluated for genetic variability compared to untreated control plants using inter-simple sequence repeat (ISSR) analysis. Polymo.. Read More»

Salicornia europaea L. Na+/H+ antiporter gene improves salt tolerance in transgenic alfalfa (Medicago sativa L.)
Authors: L.Q. Zhang, Y.D. Niu*, H. Huridu, J.F. Hao, Z. Qi and A. Hasi
In order to obtain a salt-tolerant perennial alfalfa (Medicago sativa L.), we transferred the halophyte Salicornia europaea L. Na+/H+ antiporter gene, SeNHX1, to alfalfa by using the Agrobacterium-mediated transformation method. The transformants were confirmed by both PCR and RT-PCR analyse.. Read More»

Dipterocarpus alatus (Dipterocarpaceae) is widely distributed in lowland forests in central and southern Vietnam, Cambodia, Laos, Myanmar, Philippines, Thailand, and India. Due to over-exploitation and habitat destruction, the species is now threatened. The genetic variation within and among populations of D. alat.. Read More»

Protein ubiquitination is extensively involved in the regulation of a considerable number of physiological processes in plant cells. E2 (ubiquitin-conjugating enzyme, UBC), one of the essential enzymes of eukaryotic ubiquitination, catalyzes protein ubiquitination together with E1 and E3. In this study, we cloned four full-length cDNANnUBCs of Nelumbo nuc.. Read More»
