Caracterización morfológica, molecular e histopatología de hongos ophiostomatoides asociados al pino de las alturas (Pinus hartwegii Lindl) Colegio de Postgraduados
Pérez Vera, Omar Alejandro.
Los descortezadores (Coleóptera: Curculionidae: Scolytinae) son vectores de especies de Ophiostoma spp. que causan el manchado azul de la madera y contribuyen a la muerte de árboles en coníferas y angiospermas. En México, Dendroctonus adjunctus es uno de las principales plagas de bosques de pino, Sin embargo, los hongos simbiontes que introduce en sus galerías y las alteraciones que pueden ocasionar en el sistema de conducción de agua del árbol se desconocen. Las especies del género Ophiostoma son difíciles de identificar por características morfológicas; por ello, recientemente se ha utilizado la técnica de reacción en cadena de la polimerasa (PCR) y secuencias de ADN. Por lo anterior, los objetivos de la presente investigación fueron: a)...

Compounds used to produce cloned animals are genotoxic and mutagenic in mammalian assays in vitro and in vivo BJMBR
Oliveira,R.J.; Mantovani,M.S.; da Silva,A.F.; Pesarini,J.R.; Mauro,M.O.; Ribeiro,L.R..
The compounds 6-dimethylaminopurine and cycloheximide promote the successful production of cloned mammals and have been used in the development of embryos produced by somatic cell nuclear transfer. This study investigated the effects of 6-dimethylaminopurine and cycloheximide in vitro, using the thiazolyl blue tetrazolium bromide colorimetric assay to assess cytotoxicity, the trypan blue exclusion assay to assess cell viability, the comet assay to assess genotoxicity, and the micronucleus test with cytokinesis block to test mutagenicity. In addition, the comet assay and the micronucleus test were also performed on peripheral blood cells of 54 male Swiss mice, 35 g each, to assess the effects of the compounds in vivo. The results indicated that both...

Differential water uptake kinetics in axes and cotyledons during seed germination of Vigna radiata under chilling temperature and cycloheximide treatment Braz. J. Plant Physiol.
Chakraborty,R.; Kar,R.K..
Water uptake kinetics of axes and cotyledons of Vigna radiata seeds has been studied during incubation at chilling temperature (4°C) and under cycloheximide treatment. Germination rate of scarified seeds was faster than intact seeds, which can be correlated with their comparative water uptake kinetics. Chilling temperature during incubation significantly slowed down water uptake by both intact and scarified seeds. Treatment with cycloheximide was also somewhat effective in retarding water uptake, but only in scarified seeds. Water uptake by axes isolated from intact seeds (attached or detached from the cotyledons) was inhibited completely by chilling temperature as well as by cycloheximide treatment while these treatments were ineffective in preventing...

Effects of cycloheximide on the mortality of Atta sexdens leaf-cutting worker ants Rev. Bras. entomol.
Sousa,Kátia Kaelly Andrade; Camargo,Roberto da Silva; Forti,Luiz Carlos; Caldato,Nadia.
ABSTRACT Leaf-cutting ants live symbiotically with a fungus that they cultivate on the plant leaves that they cut. The innumerous studies on the plant selection mechanism used by leaf-cutting ants show the researchers’ interest in this issue. Many classical studies propose that plants are selected according to the fungus garden nutritional needs and the absence of potentially harmful substances. This hypothesis is corroborated by behavioral experiments using cycloheximide (fungicide) with citric pulp or forage plants greatly accepted by leaf-cutting ants. According to this hypothesis, under the action of a fungicide, the fungus emits an allomone that informs worker ants that some food is inadequate to its growth. Although some authors state that the...

Long-term habituation (LTH) in the crab Chasmagnathus: a model for behavioral and mechanistic studies of memory BJMBR
A decade of studies on long-term habituation (LTH) in the crab Chasmagnathus is reviewed. Upon sudden presentation of a passing object overhead, the crab reacts with an escape response that habituates promptly and for at least five days. LTH proved to be an instance of associative memory and showed context, stimulus frequency and circadian phase specificity. A strong training protocol (STP) (<FONT FACE="Symbol">³</font>15 trials, intertrial interval (ITI) of 171 s) invariably yielded LTH, while a weak training protocol (WTP) (<FONT FACE="Symbol">£</font>10 trials, ITI = 171 s) invariably failed. STP was used with a presumably amnestic agent and WTP with a presumably hypermnestic agent. Remarkably, systemic administration of low...
