A Genome-Wide Screen for Wortmannin-Resistant Mutants in The Phosphorylation-Impaired Mutants Are Resistant to Signaling Defect.

Complex human diseases such as metabolic disorders, cancer, neurodegenerative diseases, and mitochondrial dysfunctions arise from the biochemical or genetic defects in various cellular processes. Therefore, it is important to understand which metabolic processes are affected by which cellular impairment. Because genome-wide screening of mutant collections (haploid/diploid deletion library) provides important clues for the understanding of conserved biological processes and for finding potential target genes, we screened the haploid mutant collection of with wortmannin that inhibits phosphatidylinositol-3-kinase signaling.

Small RNA and degradome deep sequencing reveals drought-and tissue-specific micrornas and their important roles in drought-sensitive and drought-tolerant tomato genotypes.

Drought stress has adverse impacts on plant production and productivity. MicroRNAs (miRNAs) are one class of noncoding RNAs regulating gene expression post-transcriptionally. In this study, we employed small RNA and degradome sequencing to systematically investigate the tissue-specific miRNAs responsible to drought stress, which are understudied in tomato.

Calli cultures from Abies equi-trojani (Aschers et Sinten) and changes in antioxidant defense system enzymes.

This study was conducted to explain difficulties of indirect regeneration of forest trees in tissue culture conditions. For this purpose, changes of antioxidant defense system enzymes; superoxide dismutase (SOD), peroxidase (POD) activities were determined during calli formation on young apical shoots of Abies equi-trojani (Aschers et Sinten). Young apical shoots were collected from naturally growing trees and cultured on two different media; Murashige and Skoog (MS) and McCown Woody plant medium (WPM) supplemented with growth regulators benzyl amino purine (BAP), 2,4-dichloro phenoxy acetic acid (2.
