Identification and functional characterization of esterases in Euschistus heros (Hemiptera, Pentatomidae) and their relationship with thiamethoxam and lambda-cyhalothrin
Authors: L.A. Hegeto, L. Ronqui, A.S. Lapenta and F.A. Albuquerque
The brown stink bug Euschistus heros is the most abundant species of the soybean-sucking bugs, and causes large economic losses. Applying different chemical groups of organosynthetic insecticides for its control increases the potential for resistance. Esterases are a group of enzymes that play a variety of roles in insects, and some of them are related to.. Read More»

Breaking dormancy in freshly matured seeds of Elymus sibiricus, an important forage grass in the Tibetan Plateau
Authors: J.Q. Zhang and Y.R. Wang
Elymus sibiricus L. is an important forage grass widely distributed in Asia and is usually a dominant species on Tibetan Plateau alpine grasslands. Here, we used the seed development indices of 1000 seed weight, seed moisture content, and seed viability to compare the seed characteristics at 10, 20, 30, 40, 50, and 60 days after anthesis (DAA) in five pop..

Molecular characterization of caj�¡, Spondias mombin (Anacardiaceae), by RAPD markers
Authors: A.T.B. Lima, V.A.B. de Souza, R.L.F. Gomes and P.S.C. Lima
The arboreal species Spondias mombin L. (Anacardiaceae) is widely distributed in Brazil, where the fruits, known by the common name of cajá, are an important commercial commodity. We evaluated genetic variability among 32 cajá accessions of the Germplasm Collection of Embrapa Meio-Norte using RAPD technique. Reac.. Read More»

Transferability and utility of white oat (Avena sativa) microsatellite markers for genetic studies in black oat (Avena strigosa)
Authors: P.R. Da-Silva, S.C.K. Milach and L.M. Tisian
Preservation and use of wild oat species germplasm are essential for further improvement of cultivated oats. We analyzed the transferability and utility of cultivated (white) oat Avena sativa (AACCDD genome) microsatellite markers for genetic studies of black oat A. strigosa (AsAs genome) genotypes. The DNA of each black oat g.. Read More»

Isolation and characterization of the promoter sequence of a cassava gene coding for Pt2L4, a glutamic acid-rich protein differentially expressed in storage roots
Authors: C.R. de Souza F.J. Arag�£o E.C.O. Moreira C.N.M. Costa S.B. Nascimento L.J. Carvalho
Cassava is one of the most important tropical food crops for more than 600 million people worldwide. Transgenic technologies can be useful for increasing its nutritional value and its resistance to viral diseases and insect pests. However, tissue-specific promoters that guarantee correct expression of transgenes would be neces.. Read More»

Evaluation of genetic diversity in Piper spp using RAPD and SRAP markers
Authors: Y. Jiang and J.-P. Liu
Random amplified polymorphic DNA (RAPD) and sequence-related amplified polymorphism (SRAP) analysis were applied to 74 individual plants of Piper spp in Hainan Island. The results showed that the SRAP technique may be more informative and more efficient and effective for studying genetic diversity of Piper spp than the RAPD te.. Read More»

Molecular cytogenetic characterization of a new leaf rolling triticale
Authors: E.N. Yang, Z.J. Yang, J.F. Zhang, Y.C. Zou and Z.L. Ren
Leaf rolling occurs in some cereal genotypes in response to drought. We identified and made a phenotypic, cytological and physiological analysis of a leaf-rolling genotype (CMH83) of hexaploid triticale (X Triticosecale Wittmack) that exhibited reduced plant height, rolled and narrow leaves. Gliadin electrophoresis of seed pro.. Read More»

Heirloom tomato gene bank: assessing genetic divergence based on morphological, agronomic and molecular data using a Ward-modified location model
Authors: L.S.A. Gon�§alves R. Rodrigues A.T. do Amaral J�ºnior M. Karasawa C.P. Sudr�©
Accessions in gene banks need to be characterized and evaluated to determine their genetic diversity. We made a joint diversity analysis of the tomato gene bank of the Universidade Estadual do Norte Fluminense Darcy Ribeiro in Rio de Janeiro state, using the Ward-modified location model. Forty Solanum lycopersicum accessions w.. Read More»

Effect of forest fragmentation on microsporogenesis and pollen viability in Eugenia uniflora, a tree native to the Atlantic Forest
Authors: Effect of forest fragmentation on microsporogenesis and pollen viability in Eugenia uniflora, a tree native to the Atlantic Forest
Habitat fragmentation, caused by the expansion of agriculture in natural areas, may be one of the strongest impacts humans have on the ecosystem. These changes can decrease the number of individuals in a population, leading to endogamy. In allogamous species, endogamy can have a negative effect on reproductive capacity. In this study, we analyzed the effe.. Read More»

Molecular evolutionary analysis of the high-affinity K+ transporter gene family in angiosperms
Authors: P. Yang, C. Hua, F. Zhou, B.-J. Zhang, X-N. Cai, Q.-Z. Chen and R.-L. Wang
The high-affinity K+ transporter (HKT) family comprises a group of multifunctional cation transporters widely distributed in organisms ranging from Bacteria to Eukarya. In angiosperms, the HKT family consists primarily of nine types, whose evolutionary relationships are not fully understood. The available sequences from 31 plant species were used to perfo..
