Characterization of agronomic and quality traits and HSW-G5 compositions from the progenies of common wheat (Triticum aestivum L.) with different protein content
Authors: M. Bian, D.K. Sun, D.F. Sun and G.L.Sun
High molecular weight glutenin subunits (HMW-GS) play an essential role in wheat processing quality. In this study, we evaluated the genetic pattern with HMW-GS composition between generations and examined whether agronomic and quality traits were correlated with each other. A wheat (Triticum aestivum L.) cultivar with high protein content and 2 cultivars.. Read More»

Cassava in South America, Brazil�s contribution and the lesson to be learned from India
Authors: Nagib M.A. Nassar
South America is responsible for about half of the cassava world production. In the 1970’s productivity of the crop on the continent was about 15 ton/ha, and dropped continuously until reaching 12 ton/ha in 2004. India’s productivity of cassava increased from 10 ton/ ha in the 1970’s to 28 ton/ha in 2004. Bra.. Read More»

Molecular cloning, characterization, and expression of Rab5B, Rab6A, and Rab7 from Litopenaeus vannamei (Penaeidae).
Authors: Y.Z. Zhao, X.L. Chen, D.G. Zeng, C.L. Yang, M. Peng and X.H. Chen
The Rab protein family belongs to a superfamily of ras-like GTP-binding proteins. Rab proteins regulate many steps of membrane trafficking. In this study, three Rab family members, Rab5B, Rab6A, and Rab7, designated LvRab5B, LvRab6A, and LvRab7, were cloned from Litopenaeus vannamei. The full-length cDNA sequences of LvRab5B, LvRab6A, and LvRab7 were 1383.. Read More»

Analysis of transferability of microsatellite primers (SSR) in wild Passiflora species and intraspecific genetic diversity in Passiflora alata
Authors: M.A.A. Silva, M.M. Souza, G.S. Silva, C.A.F. Melo, R.X. Corr�ªa, I.S. Ara�ºjo and L.D.H.C.S. Concei�§�£o
The genus Passiflora L. is the most representative of Passifloraceae, with over 500 known species, among which 150-200 originated from Brazil. In addition to the great commercial importance of this genus for the fruit market, many of the species have exotic flowers with a huge diversity of colors and can thereby be ex.. Read More»

The Candida albicans AAA ATPase homologue of Saccharomyces cerevisiae Rix7p (YLL034c) is essential for proper morphology, biofilm formation and activity of secreted aspartyl proteinases
Authors: A.S.A. Melo, A.C.B. Padovan, R.C. Serafim, L. Puzer, A.K. Carmona, L. Juliano Neto, A. Brunstein and M.R.S. Briones
Proper morphology is essential for the ability of Candida albicans to switch between yeast and hyphae and thereby sustain its virulence. Here we identified, by differential screening, a novel C. albicans AAA ATPase encoding gene, CaYLL34 (RIX7), with enhanced expression in hyphae. Phylogenetic analysis suggests that CaYLL34 be..

Effects of the plant steroidal hormone, 24-epibrassinolide, on the mitotic index and growth of onion (Allium cepa) root tips
Authors: Howell WM, Keller III GE, Kirkpatrick JD, Jenkins RL, Hunsinger RN and McLaughlin EW
The purpose of the present study was to determine the effects of the steroidal plant hormone, 24-epibrassinolide (BL), on the mitotic index and growth of onion (Allium cepa) root tips. The classical Allium test was used to gather and quantify data on the rate of root growth, the stages of mitosis, and the number of mitoses in .. Read More»

Study of chromosomal and nucleolar aspects in testes of Nysius californicus (Heteroptera: Lygaeidae)
Authors: Souza HV, Bicudo HEMC and Itoyama MM
In Nysius californicus (family Lygaeidae, subfamily Orsillinae), a pest commonly known as the seed bug, the chromosome complement is 2n = 16 (12A + 2m + XY), testes are formed by seven seminiferous tubules covered by an orange-colored membrane, and spermatogenesis is cystic. At prophase, sex chromosomes are heteropycnotic and .. Read More»

Genetic diversity of Brazilian natural populations of Anthonomus grandis Boheman (Coleoptera: Curculionidae), the major cotton pest in the New World
Authors: Martins WFS, Ayres CFJ and Lucena WA
Twenty-five RAPD loci and 6 isozyme loci were studied to characterize the genetic variability of natural populations of Anthonomus grandis from two agroecosystems of Brazil. The random- amplified polymorphic DNA data disclosed a polymorphism that varied from 52 to 84% and a heterozygosity of 0.189 to 0.347. The index of geneti.. Read More»

A two-step method for identification of the Chinese glutinous rice Suyunuo, based on ISSR-SCAR and allele-specific markers
Authors: Y.B. Lin, Y.M. Zhang, Y.Y. Hang, M.M. Li, G.C. Zhou, X.L. Shen and X.Q. Sun
Suyunuo is a valuable glutinous rice variety cultivated mainly in the Lake Taihu area of China. Historically, Suyunuo was presented to emperors as a tribute, and, still today, enjoys a great reputation in China. This study aimed to develop a unique, specific molecular marker for the identification of Suyunuo rice. Polymerase c.. Read More»

Mitochondrial genome differences between the stingless bees Melipona rufiventris and Melipona mondury (Apidae: Meliponini)
Authors: Barni GS, Strapazzon R, Guerra Jr. JCV and Moretto G
Within the Meliponini, a widely distributed group of stingless bees, Melipona rufiventris has been considered as a single, cohesive species. Recently, analysis of morphological characters led to the splitting of this species into two species, M. mondury and M. rufiventris. The former occurs in the Atlantic Rain Forest ranging ..
