Authors: X. Cao1*, X.M. Zhou1*, R. Gan2*, L.Q. Jiang2, L. Lu2, Y. Wang2, N. Fan2, Y. Yin1, N.H. Yan1, W.H. Yu1 and X.Y. Liu 2
Genetic variations within the paired box gene 6 (PAX6) gene are associated with congenital aniridia. To detect the genetic defects in a Chinese twin family with congenital aniridia and nystagmus, exons of PAX6 were amplified by polymerase chain reaction (PCR), sequenced and compared with a reference database. Six members from the family of three generatio.. Read More»

Identification and validation of a new grain weight QTL in rice
Authors: J.M. Bian, H.H. He, C.J. Li, H. Shi, C.L. Zhu, X.S. Peng, J.R. Fu, X.P. He, X.R. Chen, L.F. Hu and L.J. Ouyang
The genetic control of grain weight (GW) remains poorly understood. Quantitative trait loci (QTLs) determining the GW of rice were identified using a natural GW mutant, sgw. Using a segregating population derived from sgw (low GW) and cultivar 9311 (âÃ?Â?Ã?Â?9311âÃ?Â?Ã?Â?; indica, high GW), the chromosome segment associated with GW was detecte.. Read More»

Epistasis and inheritance of plant habit and fruit quality traits in ornamental pepper (Capsicum annuum L.)
Authors: R.M.C. Santos, E.R. do R�ªgo, A. Bor�©m, M.F. Nascimento, N.F.F. Nascimento, F.L. Finger and M.M. R�ªgo
Two accessions of ornamental pepper Capsicum annuum L., differing in most of the characters studied, were crossed, resulting in the F1 generation, and the F2 generation was obtained through self-fertilization of the F1 generation. The backcross generations RC1 and RC2 were obtained through crossing between F1 and the parents P1 and P2, respectively. Morph.. Read More»

DNA-based and geometric morphometric analysis to validate species designation: a case study of the subterranean rodent Ctenomys bicolor
Authors: J.F.B. Stolz, G.L. Gon�§alves, L. Leipnitz and T.R.O. Freitas
The genus Ctenomys (Rodentia: Ctenomyidae) shows several taxonomic inconsistencies. In this study, we used an integrative approach including DNA sequences, karyotypes, and geometric morphometrics to evaluate the taxonomic validity of a nominal species, Ctenomys bicolor, which was described based on only one specimen in 1912 by Miranda Ribeiro, and since t..

TaALMT1 promoter sequence compositions, acid tolerance, and Al tolerance in wheat cultivars and landraces from Sichuan in China
Authors: C. Han1*, S.F. Dai1*, D.C. Liu1, Z.J. Pu2, Y.M. Wei1, Y.L. Zheng1, D.J. Wen1, L. Zhao1 and Z.H. Yan1
Previous genetic studies on wheat from various sources have indicated that aluminum (Al) tolerance may have originated independently in USA, Brazil, and China. Here, TaALMT1 promoter sequences of 92 landraces and cultivars from Sichuan, China, were sequenced. Five promoter types (I', II, III, IV, and V) were observed in 39 cultivars, and only three promot..

Proline partially overcomes excess molybdenum toxicity in cabbage seedlings grown in vitro
Authors: J. Kumchai1, J.-Z. Huang2, C.-Y. Lee2, F.-C. Chen2 and S.-W. Chin2
In vitro grown cabbage (Brassica oleracea var. capitata) seedlings exposed to excess molybdenum (Mo) ions exhibited severely reduced plant growth at the cotyledonary stage. Adding 80 mM proline (Pro) to the Mo-treated medium could help 50% seedlings to overcome the toxicity and grow true leaves. Under excess Mo stress, seedlings accumulated blue/purple an.. Read More»

Establishment and molecular characterization of a sweet potato germplasm bank of the highlands of Paran�¡ State, Brazil
Authors: L.K.P. Camargo1,2, A.F. M�³gor2, J.T.V. Resende1 and P.R. Da-Silva3
The sweet potato (Ipomoea batatas L.) is a crop of great importance in developing countries, as a food staple, for animal feed, and potentially for biofuel. Development of cultivars adapted to specific regions within these countries would be useful. To start a breeding program, the first step is the establishment of a germplasm bank. We initiated a sweet .. Read More»

Identification of the isoamylase 3 gene in common wheat and its expression profile during the grain-filling period
Authors: G.Z. Kang, G.Q. Liu, W. Xu, Y.J. Zhu, C.Y. Wang, H.Q. Ling and T.C. Guo
In higher plants, isoamylase-type starch debranching enzyme catalyzes the α-1,6-glucosidic linkages of glycogen and phytoglycogen. We cloned an isoamylase-type starch debranching enzyme ISA3 cDNA sequence (2883 bp), designated as TaISA3, from common wheat (Triticum aestivum), using the rapid amplification of cDNA ends method. The open reading frame .. Read More»

Twelve introgressed oil palm (Elaeis guineensis) progenies of Nigerian dura x Deli dura were evaluated for bunch yield, yield attributes, bunch quality components and vegetative characters at the Malaysian Palm Oil Board Research Station, in Keratong, Pahang, Malaysia. Analysis of variance revealed significant to highly signif.. Read More»

The identification of germplasm genetic variability in breeding programs of the common bean (Phaseolus vulgaris) is essential for determining the potential of each combination of parent plants to obtain superior genotypes. The present study aimed to estimate the extent of genetic diversity in 172 lines and cultivars of the common bean by integrating five .. Read More»
