Salt stress-induced cell death in the unicellular green alga Micrasterias denticulata
Programmed cell death (PCD) is a key element in normal plant growth and development which may also be induced by various abiotic and biotic stress factors including salt stress. In the present study, morphological, biochemical, and physiological responses of the theoretically immortal unicellular freshwater green alga Micrasterias denticulata were examined after salt (200 mM NaCl or 200 mM KCl)...
متن کاملBeta-tubulin mutants of the unicellular green alga Chlamydomonas reinhardtii.
Two beta-tubulin mutants of the unicellular green alga Chlamydomonas reinhardtii have been isolated on the basis of altered sensitivity to the growth-inhibitory effect of colchicine. The two mutations of colR4 and colR15 have been found to be tightly linked, mapping to a previously unmarked site in linkage group XII. The drug-resistance phenotypes of both mutations segregated in genetic crosses...
متن کاملCooperative processing of primary miRNAs by DUS16 and DCL3 in the unicellular green alga Chlamydomonas reinhardtii
We have previously reported that the RNA-binding protein Dull slicer 16 (DUS16) plays a key role in the processing of primary miRNAs (pri-miRNAs) in the unicellular green alga Chlamydomonas reinhardtii. In the present report, we elaborate on the interaction of DUS16 with Dicer-like 3 (DCL3) during pri-miRNA processing. Comprehensive analyses of small RNA libraries derived from mutant and wild-t...
متن کاملSelenite transport and its inhibition in the unicellular green alga Chlamydomonas reinhardtii.
The influence of time, ambient concentration, and medium composition on selenite (Se(IV)) uptake by the unicellular green alga Chlamydomonas reinhardtii has been investigated. The aims of the performed experiments were to describe the kinetics of accumulation, to characterize transport capacities, to identify key nutrients influencing absorption, and to establish links between speciation and bi...
متن کاملChanges in the shape of mitochondria following osmotic stress to the unicellular green alga Chlamydomonas reinhardii.
The effects of various stresses on mitochondrial activity and structure within the unicellular green alga Chlamydomonas reinhardii were investigated using the fluorescent probe rhodamine 123. Within control cells, treatment with rhodamine 123 stained an intense fluorescent network, which was considered to be mitochondrial from the similarity in structure to models of mitochondria reconstructed ...
