Agropyron cristatum (P genome) is a Triticeae species from the wheat tertiary gene pool which has economic importance as forage and also displays traits beneficial to wheat. Resistance leaf rust was previously mapped short arm of chromosome 1P (1PS) in A. by development compensating Robertsonian translocation involving 1PS long 1B (1BL). In this study, engineered using ph1b mutation induce 1BS/...

We investigated twenty-six strains of Xanthidium antilopaeum Kütz. and seven strains of X. cristatum Ralfs isolated from various European localities or obtained from public culture collections. A combination of molecular, geometric morphometric, and morphological data were used to reveal the patterns of the phylogenetic and morphological differentiation of these taxonomically very compli-cated ...

Salinity, which is more common in semi-arid and arid areas, increasing every day with climate change, poor quality irrigation water, soil structure. High salt concentration restricts plant production causes productivity loss agriculture. To sustain agriculture saline soils, the determination of species resistant to salinity comes into prominence areas problems. For this reason, research was per...
