Plants are frequently exposed to microorganisms like fungi, bacteria, and viruses that cause biotic stresses. Fusarium head blight (FHB) is an economically risky wheat disease, which occurs upon graminearum (Fg) infection. Moderately susceptible (cv. "Mizrak 98") "Gun 91") winter type bread cultivars were subjected transcriptional profiling after exposure Fg To examine the early response pathogen in wheat, we measured gene expression alterations mock inoculated root crown of moderately (MS)...

Amylopectin is the principal component of starch. The amylose extender (ae) gene encodes starch-branching enzyme IIb, which critical in determining fine structure endosperm To determine relationship between amylopectin and its physical properties, rice mutant lines defective ae function with altered combination waxy (wx) background were selected for comparative studies primary wild-type starches. endosperms accumulated a high content starch long chains. wx starches showed no significant...

ABSTRACT Salinity is one of the abiotic stresses that lead to an imbalance in physiological processes plants and also affects potato growth productivity maınly semi-arid growing areas. The accumulation Na+ Cl- ions cells very toxic can influence all mechanisms enzymatic actions plants.

This work aims to characterize disproportionating enzyme (DPE1) and its isoform DPE2 in rice. Rice DPE genes (OsDPE1 OsDPE2) were cloned expressed E. coli. The OsDPE1 OsDPE2 encode proteins of 594 946 amino acids with a calculated molecular mass 67 kDa 108 kDa, respectively. Purified recombinant showed highest activity at around pH 7.0 6.0-7.0, optimum reaction temperature was 30°C for 39°C OsDPE2. Recombinant disproportionates maltotriose produce glucose maltopentaose, thus shares the...

The limited germplasm resources of hulless barley restrict the breeding with improved traits. Mutation techniques are an effective tool for generating variation plant studies.

Yalin and line YAA7050-14, were irradiated 100, 150, 200, 250, 300 gray Gamma-rays delivered by a Cobalt 60 source along non-irradiated control...

Abstract Barley is a crucial cereal crop with diverse genetic heritage that includes landraces-traditionally cultivated variants have adapted to varying agro-climatic conditions over centuries. Preserving barley landraces in genebanks of utmost importance for safeguarding diversity and aiding future breeding endeavors. This study aims an agro-morphological characterization selected collection two row conserved the Osman Tosun Genebank. A total 262 accessions were assessed controlled field...

We studied the surface structure and water adsorption behavior of waxy/amylose extender ( wx/ae ) double‐mutant rice starch using scanning electron microscopy, nitrogen gas adsorption, capacity analysis under various relative humidity conditions, nature bound in by differential calorimetry. The sample had a specific area 3.26 m 2 /g pores on its with diameters ranging from 6 to 60 nm. Its was 0.278 weight fraction molecules 0.233, both which are larger than those wx wild‐type (WT) starches....

The effects of chloride salts (NaCl, MgCl2 and CaCl2) with the same electrical conductivity (EC) values on germination, emergence, seedling growth Cl content in chickpea cultivars (Akçin 91, Aziziye, Gökçe, Inci, Iºýk-05 Yaºa-05) were investigated. EC adjusted to 4, 8 16 dS m-1 distilled water was served as control. Germination percentage, mean germination time, radicula plumula lengths, fresh dry weight, (Cl-) test, length, weight emergence test measured. results revealed that increasing...

The aim of this study was to evaluate the effect nitrogen and plant density on some morphological agronomic characteristics grain sorghum in years 2001-2002. Experimental design a split-split, randomized complete block with three replications. Three levels (0, 75 150 kg ha-1) densities (70x10, 70x20 70x30 cm) were applied cultivars. Generally, had no height stalk length. yield per usually non-significant increased tended increase plant. Both have positively affected unit area. effects...

This study investigated the regulation of gene expression in root, leaf, and grain tissues bread wheat (Triticum aestivum L.) response to drought heat stresses at grain-filling stage for first time by transcriptome analysis. The sequencing result, obtained on a Roche 454 GS FLX+, yielded total 117,790,028 base reads 8,351 unigenes with an average length 461 bp. Through analysis, numerous transcripts have been identified be involved maintaining osmotic ionic balance, detecting transmitting...
