Plant architecture is dictated by morphogenetic factors that specify the number and symmetry of lateral organs as well as their positions relative to the primary axis. Mutants defective in the patterning of leaves and floral organs have provided new insights on the signaling pathways involved, but there is comparatively little information regarding aspects of the patterning of stems, which play...
Very rapid rates of gene conversion were observed between duplicated alpha-amylase-coding sequences in Drosophila melanogaster. This gene conversion process was also seen in the related species Drosophila erecta. Specifically, there is virtual sequence identity between the coding regions of the two genes within each species, while the sequence divergence between species is close to that expecte...
Potentilla erecta (PE) is a small herbaceous plant with four yellow petals belonging to the Rosaceae family. The rhizome of PE has traditionally been used as an antidiarrheal, hemostatic and antihemorrhoidal remedy. PE contains up to 20% tannins and 5% ellagitannins, mainly agrimoniin. Agrimoniin is a hydrolyzable tannin that is a potent radical scavenger. In this study we tested the anti-infla...
A study was undertaken to compare the anatomy of the laminar floral parts with that of the spathes and leaves of Commelina erecta L. Each flower has two types of petals and two types of sepals. In contrast to the other organs, the petals have a completely open venation system whose vein endings consist solely of modified bundle-sheath cells. Bundle sheaths of leaves and spathes, but not the flo...
Plants use shade avoidance strategy to escape the canopy shade when grown under natural conditions. Previous studies showed that the Arabidopsis receptor-like kinase ERECTA (ER) is involved in shade avoidance syndrome. However, the mechanisms of ER in modulating SAR by promoting hypocotyl elongation are unknown yet. Here, we report that ER regulated hypocotyl elongation in shade avoidance requi...
Heavy metal poisoning is a serious threat in the world of industrialization as almost all the industries use heavy metals in one or the other way. These heavy metals do harm to vitals such as liver, kidney, lung and blood. Liver is the site of biotransformation of xenobiotic substances. Liver is thus the most affected affected organs of the body. The present study highlights toxic stress of mer...
The title compound, C19H20N2O·C2H5OH, is an ethanol solvate of an indol alkaloid which was extracted from the plant Vinca erecta. The fused piperidine ring adopts an approximate boat conformation and the pyrrolidine ring an envelope conformation with one of the methyl-ene C atoms at the flap. An intra-molecular N-H⋯O hydrogen bond forms an S6 ring motif. In the crystal, norfulorocurarine and et...
