Remodeled respiration in ndufs4 with low phosphorylation efficiency suppresses Arabidopsis germination and growth and alters control of metabolism at night.

Respiratory oxidative phosphorylation is a cornerstone of cellular metabolism in aerobic multicellular organisms. The efficiency of this process is generally assumed to be maximized, but the presence of dynamically regulated nonphosphorylating bypasses implies that plants can alter phosphorylation efficiency and can benefit from lowered energy generation during respiration under certain conditions. We characterized an Arabidopsis (Arabidopsis thaliana) mutant, ndufs4 (for NADH dehydrogenase [ubi ...[more]

Transcription profiling of EDS1- and SA-dependent genes in nudt7-1

Project description:nudt7-1 mutant plant exhibit stunted growth, enhanced basal resistance, elevated SA levels and spontaneous leaf cell death that is restricted to single cells but does not spread. All of these phenotypes depend on EDS1, a key regulator of plant innate immunity. Moreover, SA depletion in nudt7-1 results in EDS1-dependent cell death exacerbation and strong growth retardation. In this this experiment, we used 4-week-old soil-grown plants to seek for EDS1- and SA-regulated genes in nudt7-1 to identify novel components of the EDS1- and SA-signalling pathways.

microRNA expression profile in isolated human pancreatic islets and in human pancreatic islet-derived extracellular vesicles -EVs-

Project description:Human pancreatic islets were isolated from pancreas of deceased donors by Ricordi's procedure and cultured in CMRL 1066 medium additioned with human albumin. EVs were isolated from conditioned medium derived from islet culture after isolation. Once isolated, RNA of islets and islet-derived EVs was extracted and analyzed for microRNA expression within 48 hours after isolation.

Transcription profiling of Arabidopsis thaliana LFY mutant plants transformed with different LFY orthologs to investigate evolutionary divergence of LFY function

Project description:The aim of this experiment is to test the ability of the ortholog of Arabidopsis LFY gene from flowering and non flowering species to complement an Arabidopsis LFY mutant. Plants expressing, in a homozygous lfy12 background, the open reading frame of LFY orthologs under the control of Arabidopsis LFY promoter were synchronously induced to flower by growing plants in short days for 30 days then shifting them to Long Day for an additional 8 days. Shoot apices were dissected at either d0 or d8 in long days. Two biological replicates were performed. The following genotypes were used: Col - wild type arabidopsis; reference strain LFY (lfy12; LFY::AthLFY) - Arabidopsis UNI (lfy12; LFY::UNI) - Pisum ALF (lfy12; LFY::ALF) - Petunia WelNDLY (lfy12; LFY::WelNDLY) - Welwitschia mirabilis CrLFY1 (lfy12; LFY::CrLFY1) - Ceratopteris richardii CrLFY2 (lfy12; LFY::CrLFY2) - Ceratopteris richardii lfy-2; weak lfy allele lfy-9; intermediate leafy allele lfy-12; strong leafy allele.
