Pre-Harvest Sprouting Resistance in Bread Wheat: A Speed Breeding Approach to Assess Dormancy QTL in Backcross Lines.

In this study, BC1F3:4 generation plants derived from the hybrid crosses of Rio Blanco × Nevzatbey, Rio Blanco × Adana99, and Rio Blanco × line 127 were used as experimental material. These hybrids incorporated QTLs associated with pre-harvest sprouting (PHS) resistance through molecular techniques. Key agronomic traits, including plant height, spike length, the number of grains per spike, grain weight, and physiological maturity, were evaluated in both greenhouse and growth room settings under accelerated growth (speed breeding) conditions.

Planting Geometry May Be Used to Optimize Plant Density and Yields without Changing Yield Potential per Plant in Sweet Corn.

Planting geometry is one of the most important management practices that determine plant growth and yield of corn. The effects of eight planting geometries (35 × 23 cm, 40 × 21 cm, 45 × 19 cm, 50 × 18 cm, 55 × 17 cm, 60 × 16 cm, 65 × 15 cm, 70 × 15 cm) on plant growth and yields of three sweet corn hybrids (Argos F, Challenger F, Khan F) were investigated under Erzurum, Türkiye conditions in 2022 and 2023 years. Variance analysis of the main factors shows a highly significant effect on whole traits but in two-way interactions some of the traits were significant and in the three-way interactions, it was insignificant.

Investigation of the Influence of Polyamines on Mature Embryo Culture and DNA Methylation of Wheat ( L.) Using the Machine Learning Algorithm Method.

Numerous factors can impact the efficiency of callus formation and regeneration in wheat cultures through the introduction of exogenous polyamines (PAs). The present study aimed to investigate plant regeneration and DNA methylation patterns utilizing the inter-primer binding site (iPBS) retrotransposon and coupled restriction enzyme digestion-iPBS (CRED-iPBS) methods in wheat. This investigation involved the application of distinct types of PAs (Put: putrescine, Spd: spermidine, and Spm: spermine) at varying concentrations (0, 0.

Genetic Diversity and Population Structure in Türkiye Bread Wheat Genotypes Revealed by Simple Sequence Repeats (SSR) Markers.

Wheat genotypes should be improved through available germplasm genetic diversity to ensure food security. This study investigated the molecular diversity and population structure of a set of Türkiye bread wheat genotypes using 120 microsatellite markers. Based on the results, 651 polymorphic alleles were evaluated to determine genetic diversity and population structure.

Effects of mammalian sex hormones on in vitro organogenesis of common bean (Phaseolus vulgaris L.).

Beans are an important plant species and are one of the most consumed legumes in human nutrition, especially as a protein, vitamin, mineral, and fiber source. Common bean (Phaseolus vulgaris L.) is a plant that also has an important role in natural nitrogen fixation.

Mutagenic effects of sodium azide on in vitro mutagenesis, polymorphism and genomic instability in wheat (Triticum aestivum L.).

Introduction: Breeding studies are commonly conducted to develop new cultivars with high yield levels and improved quality traits. Chemically-induced mutations are used to create genetic variations in wheat genomes. Various physical and chemical mutagens are used to increase frequency of mutations and facilitate the selection processes.

Improvement of Drought Tolerance by Exogenous Spermidine in Germinating Wheat ( L.) Plants Is Accompanied with Changes in Metabolite Composition.

Drought is one of the most important environmental factors reducing the yield and production of crops, including wheat. Polyamines are closely associated with plant stress tolerance. The present study investigated the mechanisms through seed germination with spermidine protecting wheat varieties from drought stress.

Determining Genetic Diversity and Population Structure of Common Bean ( L.) Landraces from Türkiye Using SSR Markers.

Assessment of genetic diversity among different varieties helps to improve desired characteristics of crops, including disease resistance, early maturity, high yield, and resistance to drought. Molecular markers are one of the most effective tools for discovering genetic diversity that can increase reproductive efficiency. Simple sequence repeats (SSRs), which are codominant markers, are preferred for the determination of genetic diversity because they are highly polymorphic, multi-allelic, highly reproducible, and have good genome coverage.

The Effect of Mammalian Sex Hormones on Polymorphism and Genomic Instability in the Common Bean ( L.).

Mammalian sex hormones are steroid-structured compounds that support the growth and development of plants at low concentrations. Since they affect the physiological processes in plants, it has been thought that mammalian sex hormones may cause modifications to plant genomes and epigenetics. This study aims to determine whether different mammalian sex hormones (17 β-estradiol, estrogen, progesterone, and testosterone) in several concentrations (0, 10, 10, and 10 mM) affect genetic or epigenetic levels in bean plants, using in vitro tissue cultures from plumule explants.

iPBS-Retrotransposon Markers in the Analysis of Genetic Diversity among Common Bean ( L.) Germplasm from Türkiye.
