Diversity of endophytic bacteria in Brazilian sugarcane
Authors: G.S. Magnani, C.M. Didonet, L.M. Cruz, C.F. Picheth, F.O. Pedrosa and E.M. Souza
Endophytic bacteria live inside plant tissues without causing disease. Studies of endophytes in sugarcane have focused on the isolation of diazotrophic bacteria. We examined the diversity of endophytic bacteria in the internal tissues of sugarcane stems and leaves, using molecular and biochemical methods. Potato-agar medium wa.. Read More»

Gelling agents and culture vessels affect in vitro multiplication of banana plantlets
Authors: Y.A. Ka�§ar, B. Bi�§en, �°. Varol, Y.Y. Mendi, S. Ser�§e and S. ��etiner
Agar is the most commonly used gelling agent in media for plant tissue culture. Because of the high price of tissue-culture-grade agar, attempts have been made to identify suitable alternatives. The type of culture vessel and lid also affects the gaseous composition inside the vessel as well as light penetration. In turn, the .. Read More»

Optimization of DNA extraction from seeds and fresh leaf tissues of wild marigold (Tagetes minuta) for polymerase chain reaction analysis
Authors: I. Shahzadi, R. Ahmed, A. Hassan and M.M. Shah
Tagetes, a genus of flowering marigolds in the family Asteraceae (Compositeae), is reported to be a medicinal plant with hypotensive, spasmolytic, anti-inflammatory, antimicrobial, and antifungal properties. Tagetes minuta characteristically contains high concentrations of essential oils, flavonoids, polyphenols, and polysacch.. Read More»

Molecular cloning and characterization of a chlorophyll degradation regulatory gene (ZjSGR) from Zoysia japonica
Authors: K. Teng, Z.H. Chang, G.Z. Xiao, W.E. Guo, L.X. Xu, Y.H. Chao and L.B. Han
The stay-green gene (SGR) is a key regulatory factor for chlorophyll degradation and senescence. However, to date, little is known about SGR in Zoysia japonica. In this study, ZjSGR was cloned, using rapid amplification of cDNA ends-polymerase chain reaction (PCR). The target sequence is 831 bp in length, corresponding to 276 .. Read More»

Improvement of a popcorn population using selection indexes from a fourth cycle of recurrent selection program carried out in two different environments
Authors: A.T. Amaral J�ºnior, S.P. Freitas J�ºnior, R.M. Rangel, G.F. Pena, R.M. Ribeiro, R.C. Morais and A.R. Schuelter
We estimated genetic gains for popcorn varieties using selection indexes in a fourth cycle of intrapopulation recurrent selection developed in the campus of the Universidade Estadual do Norte Fluminense. Two hundred full-sib families were obtained from the popcorn population UNB-2U of the third recurrent selection cycle. The p.. Read More»

Adaptability and phenotypic stability of common bean genotypes through Bayesian inference
Authors: A.M. Corr�ªa, P.E. Teodoro, M.C. Gon�§alves, L.M.A. Barroso,M. Nascimento, A. Santos and F.E. Torres
This study used Bayesian inference to investigate the genotype x environment interaction in common bean grown in Mato Grosso do Sul State, and it also evaluated the efficiency of using informative and minimally informative a priori distributions. Six trials were conducted in randomized blocks, and the grain yield of 13 common .. Read More»

SSR-based molecular analysis of economically important Turkish apricot cultivars
Authors: A.E. Akp�±nar, H. Ko�§al, A. Erg�¼l, K. Kazan, M.E. ��elli, M. Bak�±r, ��. Aslanta��, S. Kaymak and R. Sar�±ba��
Turkey is not only the main apricot (Prunus armeniaca) producer and exporter in the world, but it also has a wide variety of apricot germplasms, owing to its close proximity to the centers of apricot origin. However, there is little or no genetic information on many apricot cultivars that are extensively cultivated in Turkey. .. Read More»

Jasmonates are phytohormones with multiple functions, including plant defense and reproduction
Authors: N.C. Avanci, D.D. Luche, G.H. Goldman and M.H.S. Goldman
The plant hormones jasmonic acid and methyl jasmonate, along with their intermediate compounds, produced in the octadecanoid pathway, are important signaling molecules that are collectively called jasmonates. These are widespread in the plant kingdom and play crucial roles in biotic/abiotic stress responses, as well as in proc.. Read More»

DNA profiling of sugarcane genotypes using randomly amplified polymorphic DNA
Authors: S. Tabasum, F.A. Khan, S. Nawaz, M.Z. Iqbal and A. Saeed
DNA profiles of 40 sugarcane genotypes were constructed with 30 RAPD markers. Sugarcane genotypes of both Saccharum officinarum and S. barberi were included in this study. Multiple alleles were detected from each RAPD; there was a high level of polymorphism. On average, 7.93 alleles were produced per primer, giving a total of .. Read More»

Genetic diversity analysis of Aspergillus flavus isolates from plants and air by ISSR markers
Authors: M.A. Mahmoud, A.M.A. El-Samawaty, M.A. Yassin and A.R.M. Abd El-Aziz
Aspergillus flavus is one of the most abundant and widely distributed fungi on earth. A. flavus produces aflatoxins (AFs), which are toxic secondary metabolites. AFs have harmful effects on public health (humans and animals) and agricultural crops. Inter-simple sequence repeat (ISSR) markers were used to analyze the genetic di.. Read More»
