background: we describe karyotypic variations and the in vitro methods for plant propagation and conservation as well as detailed chromosomal analysis of (aloe vera l.) and aloe littoralis from iran during flowering stage. objectives: this karyotypic was discovered because of a difference in the position of the chromosome and due to genomic differentiation in domesticated populations of the ira...

The authors imparted the main concept of infochemical communication and its realization in the first micromachinebased chemoemitter. We present herein details on the microfabrication and functionality of its elements, particularly the biomicroreactor and the evaporator. The functionality of the integrated chemoemitter has been evidenced in an electrophysiological assay using antennae of male Sp...

Extracellular self-DNA (esDNA) is produced during cell and tissue damage or degradation and has been shown to induce significant responses in several organisms, including plants. While the inhibitory effects of esDNA have been shown in conspecific individuals, little is known on the early events involved upon plant esDNA perception. We used electrophysiology and confocal laser scanning microsco...

The negative fitness consequences of close inbreeding are widely recognized, but predicting the long-term effects of inbreeding and genetic drift due to limited population size is not straightforward. As the frequency and homozygosity of recessive deleterious alleles increase, selection can remove (purge) them from a population, reducing the genetic load. At the same time, small population size...

Aeluropus littoralis is a monocot halophyte grass and provide valuable genetic resources for understanding the molecular mechanisms of stress-responsive genes, and improving tolerance to abiotic stresses in economically important crops. In an attempt to identify salt stressed responsive genes, 154 isolated expressed sequence tags (EST) from A. littoralis were bioinformatically analyzed and func...

BACKGROUND Various proteins that display carbohydrate-binding activity in a Ca(2+)-dependent manner are classified into the C-type lectin family. They have one or two C-type carbohydrate-recognition domains (CRDs) composed of 110-130 amino acid residues in common. C-type lectins mediate cell adhesion, non-self recognition, and immuno-protection processes in immune responses and thus play signif...

The monotypic genera Epiplagiops Blanchard, 1943 and Tetragrapha Brauer and Bergenstamm, 1891 are revised. Both are invalidated and synonymized with Chetogena Rondani, 1856. Their type-species, Epiplagiops littoralis Blanchard, 1943 and Tetragrapha tessellata Brauer and Bergenstamm, 1891, are studied, redescribed, illustrated, and transferred to Chetogena. A lectotype is designated for T. tesse...
