Molybdenum cofactor sulfurases (MCSUs) are important enzymes for plant development and response to environmental queues, including processes such as nitrogen metabolism and regulation of the abscisic acid levels in plant tissues. We cloned and sequenced MCSU gene from barley and performed in silico comparison with rice, tomato, and Arabidopsis. Physico-chemical properties and subcellular predictions were found to be similar in different plant species. All MCSUs had three critical domains: aminotransferase class-V (Pfam: PF00266), MOSC N-terminal beta barrel (Pfam: PF03476), and MOSC (Pfam: PF03473). Secondary structure analysis revealed that random coils were the most abundant, followed by α-helices and extended strands. …

Turkish Journal of Agriculture and Forestry
Numerous diseases caused by fungal pathogens influence the annual production of sugar beet. In order to obtain a plant resistant to fungi, genetic transformation has been applied to the sugar beet. To invade a plant tissue, phytopathogenic fungi produce several cell wall-degrading enzymes (CWDEs); polygalacturonases (PGs) are pathogenicity factors produced at the earlier stages of a fungal infection that depolymerize the homogalacturonan. One of the strategies used by plants to limit the degradation of the cell wall polysaccharides by fungal CWDEs is the production of proteinaceous inhibitors. Against fungal, microbial, and insect PGs, plants produce cell wall-associated polygalacturonase-inhibiting proteins (PGIPs). …

Turkish Journal of Agriculture and Forestry
Lentil, which belongs to the family Leguminosae (Fabaceae), is a diploid (2n = 2x = 14 chromosomes) self-pollinating crop with a genome size of 4063 Mbp. Because of its nutritional importance and role in the fixation of nitrogen from the atmosphere, lentil is a widely used crop species in molecular genetic studies. By using DNA markers, to date, a limited number of polymorphic bands have been generated. Therefore, it is necessary to develop additional markers to saturate the genome at high density. Single nucleotide polymorphism (SNP) markers are promising for this purpose because of their abundance, stability, and heredity; they …

Impacts Of Logging And Prescribed Burning In Longleaf Pine Forests Managed Under Uneven-Aged Silviculture, Ferhat Kara, Edward Francis Loewenstein
Impacts Of Logging And Prescribed Burning In Longleaf Pine Forests Managed Under Uneven-Aged Silviculture, Ferhat Kara, Edward Francis Loewenstein
Turkish Journal of Agriculture and Forestry
The longleaf pine (Pinus palustris Mill.) ecosystem has historically been very important in the southeastern United States due to its extensive area and high biodiversity. Successful regeneration of longleaf pine forests requires an adequate number of well-distributed seedlings. Thus, mortality of longleaf pine seedlings during logging operations and prescribed burning appears to be important. Longleaf forests have been commonly managed using even-aged silvicultural methods, but, recently, interest in the use of uneven-aged (UEA) methods has increased in these forests. Research on the impact of UEA logging in longleaf forests is limited. In addition, the influence of overstory density on the …
