Authors: M.A. Rodrigues, E.P. Amorim, C.F. Ferreira, C.A.S. Ledo and J.R.F. Santana
Natural fruit finger drop in bananas is one of the major concerns of producers as well as consumers. The aim of this study was to estimate the genetic diversity among 15 diploid bananas with different levels of resistance to finger drop (RFD) using SSR and ISSR (inter-simple sequence repeat) markers, and assess the possibility..

Genetic relationship among Labisia pumila (Myrsinaceae) species based on ISSR-PCR
Authors: E. Karimi, H.Z.E. Jaafar, M.A. Aziz, S. Taheri and R. AzadiGonbad
The genus Labisia (Myrsinaceae) is a popular medicinal plant in Malaysia. We examined the genetic relationship among three varieties of L. pumila var. pumila, L. pumila var. alata, L. pumila var. lanceolata and Labisia paucifolia using an ISSR assay. Fifty-eight primers were tested, among which 18 gave reliable polymorphic ban.. Read More»

High genetic variation among Aschersonia placenta (Clavicipitaceae) isolates from citrus orchards in China
Authors: P.P. Wang1,2, X.H. Song1,3 and H.Y. Zhang
Aschersonia placenta had been recognized as an important fungal pathogen of whiteflies. In recent years, natural occurrence of Aschersonia in whitefly populations was observed in many citrus orchards in the southern regions of China. We analyzed 60 A. placenta isolates obtained from Chinese citrus orchards, using inter-simple sequence repeats to examine t.. Read More»

Genetic diversity in natural populations of Theobroma subincanum Mart. in the Brazilian Amazon
Authors: L.H. Rivas1, L.D. Giustina1, L.N. Luz2, I.V. Karsburg1, T.N.S. Pereira2 and A.A.B. Rossi1
The genus Theobroma, recently reclassified in the family Malvaceae, comprises some species with high economic potential, including the cupuí, Theobroma subincanum Mart., which has not yet been domesticated, and whose genetics and population structure are mostly unknown. This study aimed to assess the population structure and genetic diversity in na.. Read More»

Genetic diversity of spineless Cereus jamacaru accessions using morphological and molecular markers
Authors: F.I.C. Oliveira, P.N. Bordallo, A.C.R. Castro and D. Correia
This is the first study to examine the genetic diversity of mandacaru cactus (Cereus jamacaru P. DC.). Plants of spineless mandacaru are commonly found in gardens and parks of urban areas in northeastern Brazil. In addition to exploring their ornamental potential, morphological, and genetic characterization may contribute to the development of plant mater.. Read More»

Genetic diversity of Cosmos species revealed by RAPD and ISSR markers
Authors: A. Rodr�?guez-Bernal, J.L. Pi�?±a-Escutia, L.M. V�?¡zquez-Garc�?a and A.M. Arzate-Fern�?¡ndez
The genus Cosmos is native of America and is constituted by 34 species; 28 of them are endemic of Mexico. The cosmos are used as a nematicide, antimalarial, and antioxidative agent. The aim of this study was to estimate the genetic diversity among 7 cosmos species based on random amplified polymorphic DNA (RAPD) and inter-simple sequences repeats (ISSR) m.. Read More»

Capsicum species are frequently described in terms of genetic divergence, considering morphological, agronomic, and molecular databases. However, descriptions of genetic differences based on anatomical characters are rare. We examined the anatomy and the micromorphology of vegetative and reproductive organs of several Capsicum species. Four Capsicum acces.. Read More»

Identification of hybrids between triticale and Aegilops juvenalis (Thell.) Eig and determination of genetic similarity with ISSRs
Authors: A. Gradzielewska, D. Gruszecka, J. Le�?�?niowska-Nowak and E. Paczos-Grz�?�?da
Wide hybridization expands the gene pool of cultivated species and can produce genotypes with practical value, often resistant to diseases. In plants, ISSRs are often used for hybrid identification as well as for diversity evaluation. We estimated genetic similarity among advanced genetic stocks of triticale hybrids and identified Aegilops juvenalis intro.. Read More»
