Carotenoid cleavage oxygenases (CCOs) are a family of dioxygenases, which specifically catalyze the cleavage of conjugated double bonds in carotenoids and apocarotenoids in plants. In this study, genome-wide analysis of CCO genes in pepper plants was performed using bioinformatic methods. At least 11 members of the CCO gene fa.. Read More»

Selection of sorghum hybrids grown under aluminum saturation
Authors: C.B. Menezes, G.A. Carvalho Junior, L.A. Silva, K.C. Bernardino, J.V. Magalh�£es, C.T. Guimar�£es, L.J.M. Guimar�£es and R.E. Schaffert
The purpose of this study was to evaluate 165 hybrids derived from lines previously selected for aluminum (Al) tolerance. Nine check cultivars were used, eight commercial hybrids and one experimental hybrid. Hybrids were evaluated at three levels of Al saturation (0, 20 and 40% on average). The differences between the environm.. Read More»

Molecular characterization and functional analysis of a Flowering locus T homolog gene from a Phalaenopsis orchid
Authors: D.M. Li, F.B. LÃ?Â?, G.F. Zhu, Y.B. Sun, H.L. Liu, J.W. Liu and Z. Wang
Warm day and cool night conditions significantly induce reproductive spike formation in Phalaenopsis plants; hence, determining the flowering mechanism regulating the reproductive transition is important. Flowering locus T (FT) plays important roles in flowering induction in several plants. To explore spike i.. Read More»

Use of a synthetic lethal screen to identify genes related to TIF51A in Saccharomyces cerevisiae
Authors: Frigieri MC, Thompson GM, Pandolfi JR, Zanelli CF and Valentini SR
The putative eukaryotic translation initiation factor 5A (eIF5A) is an essential protein for cell viability and the only cellular protein known to contain the unusual amino acid residue hypusine. eIF5A has been implicated in translation initiation, cell proliferation, nucleocytoplasmic transport, mRNA decay, and actin polariza..

Isolation and characterization of NBS-LRR- resistance gene candidates in turmeric (Curcuma longa cv. surama)
Authors: R.K. Joshi, S. Mohanty, E. Subudhi and S. Nayak
Turmeric (Curcuma longa), an important asexually reproducing spice crop of the family Zingiberaceae is highly susceptible to bacterial and fungal pathogens. The identification of resistance gene analogs holds great promise for development of resistant turmeric cultivars. Degenerate primers designed based on known resistance ge.. Read More»

B chromosomes in popcorn (Zea mays L.)
Authors: Ricci GL, Silva N, Pagliarini MS and Scapim CA
Cytological analysis of microsporogenesis in 72 popcorn plants, comprising nine from the original population (CMS-43, S0) and 63 from seven cycles of self-fertilization (S1 to S7), one plant of S0 generation (plant 2) was identified with B chromosomes. The number of B chromosomes varied from two to three in the same anther. Th.. Read More»

Temporal genetic differentiation in cultured and natural beds of the brown mussel Perna perna (Mytilidae)
Authors: Appio KT and Weber LI
Perna perna is the most important cultivated mussel of Santa Catarina, Brazil, sustaining an important economic input for many local families. Natural stocks of P. perna are depleted by the extraction of adults and seeds for consumption and culture. The aim of the present study was to use the microsatellite locus pms-2 to stud.. Read More»

Identification of floral genes for sex determination in Calamus palustris Griff. by using suppression subtractive hybridization
Authors: C.Y. Ng, R. Wickneswari and C.Y. Choong
Calamus palustris Griff. is an economically important dioecious rattan species in Southeast Asia. However, dioecy and onset of flowering at 3-4 years old render uncertainties in desired female:male seedling ratios to establish a productive seed orchard for this rattan species. We constructed a subtractive library for .. Read More»

Assessment of phylogenetic relationship of rare plant species collected from Saudi Arabia using internal transcribed spacer sequences of nuclear ribosomal DNA
Authors: F. Al-Qurainy, S. Khan, M. Nadeem, M. Tarroum and A. Alaklabi
The rare and endangered plants of any country are important genetic resources that often require urgent conservation measures. Assessment of phylogenetic relationships and evaluation of genetic diversity is very important prior to implementation of conservation strategies for saving rare and endangered plant species. We used internal transcribed spacer se.. Read More»

Cassava diversity in Brazil: the case of carotenoid-rich landraces
Authors: Nagib Nassar, Vizzotto CS, Schwartz CA and Pires Junior OR
In Brazil, the center of cassava origin, cassava landraces have acquired through their domestication a large diversity in relation to many economic traits such as high content of carotenoids and excellent palatability among other characters. One of these clones, which has been grown by indigenous Brazilian farmers and is now b.. Read More»
