Abstract— Cereinae comprises 14 genera distributed in Neotropical dry forest formations such as the Caatingas of northeastern Brazil or rocky outcrops north southeastern Brazil. Historically, taxonomy group has been very controversial, especially regarding generic circumscriptions, and phylogenetic relationships within are still poorly understood. To investigate delimitation subtribe infra-subt...

Significant advances in sequencing technologies and genome-wide association studies (GWAS) have revealed substantial insight into the genetic architecture of human phenotypes. In recent years, the application of this approach in bacteria has begun to reveal the genetic basis of bacterial host preference, antibiotic resistance, and virulence. Here, we consider relevant differences between bacter...

Phytic acid (myo-inositol hexakisphosphate, InsP(6)) hydrolysis by Bacillus phytase (PhyC) was studied. The enzyme hydrolyses only three phosphates from phytic acid. Moreover, the enzyme seems to prefer the hydrolysis of every second phosphate over that of adjacent ones. Furthermore, it is very likely that the enzyme has two alternative pathways for the hydrolysis of phytic acid, resulting in t...

We have used a nove1 assay based on protein fusions with h repressor to identify two small regions within phytochrome’s carboxy-terminal domain that are capable of mediating dimerization. Using an in vivo assay, fusions between the DNA binding, amino-terminal domain of h repressor and fragments from oat PhyA phytochrome have been assayed for increased repressor activity, an indicator of dimeriz...

The global transition state regulator AbrB controls more than 100 genes of the Bacillus relatives and is known to interact with varying DNA-sequences. The DNA-binding domain of the AbrB-like proteins was proposed to be located exclusively within the amino-terminal ends. However, the recognition of DNA, and specificity of the binding mechanism, remains elusive still in view of highly differing r...

Phylogenetic data from plastid (ndhF and rbcL) and nuclear (PHYC) genes indicate that, within the order Malpighiales, Elatinaceae are strongly supported as sister to Malpighiaceae. There are several putative morphological synapomorphies for this clade; most notably, they both have a base chromosome number of X = 6 (or some multiple of three or six), opposite or whorled leaves with stipules, uni...

We have used a novel assay based on protein fusions with lambda repressor to identify two small regions within phytochrome's carboxy-terminal domain that are capable of mediating dimerization. Using an in vivo assay, fusions between the DNA binding, amino-terminal domain of lambda repressor and fragments from oat PhyA phytochrome have been assayed for increased repressor activity, an indicator ...
