Proteomic analysis of naturally occurring boron tolerant plant Gypsophila sphaerocephala L. in response to high boron concentration.

Gypsophila sphaerocephala is a naturally Boron (B) tolerant species that can grow around the B mining areas in Turkey, where the B concentration in soil reaches a lethal dose for plants (up to ∼8900mgkg (∼140mM). While its interesting survival capacity in extremely B containing soils, any molecular research has been conducted to understand its high tolerance mechanism yet. In the present study, we have performed a proteomic analysis of this plant to understand its high tolerance towards B-stress.

High-throughput transcriptome analysis of barley (Hordeum vulgare) exposed to excessive boron.

Boron (B) is an essential micronutrient for optimum plant growth. However, above certain threshold B is toxic and causes yield loss in agricultural lands. While a number of studies were conducted to understand B tolerance mechanism, a transcriptome-wide approach for B tolerant barley is performed here for the first time.

Randomly amplified polymorphic-DNA analysis for detecting genotoxic effects of Boron on maize (Zea mays L.).

This study was carried out to investigate the genotoxic effect of boron (B) on maize using randomly amplified polymorphic DNA (RAPD) method. Experimental design was conducted under 0, 5, 10, 25, 50, 100, 125, and 150 ppm B exposures, and physiological changes have revealed a sharp decrease in root growth rates from 28% to 85%, starting from 25 ppm to 150 ppm, respectively. RAPD-polymerase chain reaction (PCR) analysis shows that DNA alterations are clearly observed from beginning to 100 ppm.

Transcriptome-wide identification of R2R3-MYB transcription factors in barley with their boron responsive expression analysis.

MYB family of transcription factors (TF) comprises one of the largest transcription factors in plants and is represented in all eukaryotes. They include highly conserved MYB repeats (1R, R2R3, 3R, and 4R) in the N-terminus. In addition to this, they have diverse C-terminal sequences which help the protein gain wide distinct functions, such as controlling development, secondary metabolism, hormonal regulation and response to biotic and abiotic stress.

Genotoxic effects of catmint (Nepeta meyeri Benth.) essential oils on some weed and crop plants.

This study investigates the genotoxicity of the essential oils extracted from the aerial parts of catmint (Nepeta meyeri Benth.) against two weeds (Bromus danthoniae and Lactuca serriola) and two crop plants (Brassica napus and Zea mays). The essential oils of N.
