A DUPLICATED COPY OF THE MEIOTIC GENE ZIP4 PRESERVES UP TO 50% POLLEN VIABILITY AND GRAIN NUMBER IN POLYPLOID WHEAT

A Duplicated Copy of the Meiotic Gene ZIP4 Preserves up to 50% Pollen Viability and Grain Number in Polyploid Wheat

Although most flowering plants are polyploid, little is known of how the meiotic process evolves after polyploidisation to stabilise and preserve fertility.On wheat polyploidisation, the major meiotic gene ZIP4 on chromosome 3B duplicated onto 5B and diverged (TaZIP4-B2).TaZIP4-B2 was recently shown to promote homologous pairing, synapsis and cross

MODCEL-MHUS: a comprehensive multilayer hydrodynamic unified simulation for stormwater, sanitary sewer systems, and urban surface

Numerous countries and regions have embraced implementing a separate sewer system, segregating sanitary and storm sewers into distinct systems.However, the functionality Books of these systems often needs to improve due to irregular interconnections, resulting in a mixed and malfunctioning system.Sewage collection is crucial for residential sanitat
