Background & Aim: Satureja khuzistanica Jamzad. is an aromatic and medicinal perennial plant belongs to family mint (Lamiaceae). It is also an Iranian exclusive endemic species, its essential oil components are widely used in medicinal, culinary, and perfume industries. Experimental: Flowers were collected in 10 regions in Khuzistan and Lorestan provinces, Iran at early anthesis durin...

Transcription through immunoglobulin switch (S) regions is essential for class switch recombination (CSR), but no molecular function of the transcripts has been described. Likewise, recruitment of activation-induced cytidine deaminase (AID) to S regions is critical for CSR; however, the underlying mechanism has not been fully elucidated. Here, we demonstrate that intronic switch RNA acts in tra...

Self-incompatibility (SI) in angiosperms is a genetic mechanism that promotes outcrossing through rejection of self-pollen. In the Solanaceae, SI is determined by a multiallelic S locus whose only known product is an S RNase. S RNases show a characteristic pattern of five conserved and two hypervariable regions. These are thought to be involved in the catalytic function and in allelic specifici...

Class switch DNA recombination (CSR) of the immunoglobulin heavy chain (IgH) locus crucially diversifies antibody biological effector functions. CSR involves the induction of activation-induced cytidine deaminase (AID) expression and AID targeting to switch (S) regions by 14-3-3 adaptors. 14-3-3 adaptors specifically bind to 5'-AGCT-3' repeats, which make up for the core of all IgH locus S regi...

Tricholoma matsutake is an ectomycorrhizal fungus that has obligate symbiotic relationships with Pinus densiflora. Its fruiting body a distinctive flavor and traded at high price. Thus, it been significant source of income for rural communities in Korea. We hypothesized biotic factors considerably influence the formation T. mushroom, soils producing share similar microbial characteristics. Ther...

The five H-2t haplotypes are all intra-H-2 recombinants which have identical K and D regions, but differ in the central regions of the complex. Analyses of H-2, Ia and Ss-Slp types indicate that the crossover in H-2t1 took place between the K and I regions, in the H-2t2 between G and D, in H-2t3 and H-2t4 between the I-B and I-C subregions and in H-2t5 between I and S. The set of recombinants w...

We propose an empirical sulphur abundance determination method based on the strong sulphur emission lines, [S ii] λλ6716, 6731 and [S iii] λλ9069, 9531 in H ii regions. From a compilation of literature data we have made a calibration of sulphur abundance versus ([S ii] + [S iii])/Hβ, similar to what has been widely used for the more easily observable iso-electronic element oxygen. This enables ...
