Developmental staging of maize microspores reveals a transition in developing microspore proteins.
A method for the preparation of developmentally staged microspores and young pollen from maize (Zea mays) has been devised. The preparations are of sufficient purity and quantity for biochemical analysis, including the analysis of steady-state protein and RNA populations associated with each stage. A major transition in protein populations occurs during the developmental period that encompasses...

متن کاملAssociation of Floral Bud and Anther Size with Microspore Developmental Stage in Campari Tomato
Successful anther/microspore culture largely depends on the use of microspores at appropriate developmental stages at the time of culture, which can be specific for each plant species and genotype. This study was carried out to determine the correlation between morphological characteristics, namely floral bud (FB) length and width and anther length, and specific microspore developmental stages ...
متن کاملGenetic Diversity Analysis of Maize Hybrids Through Morphological Traits and Simple Sequence Repeat Markers
Comparing different methods of estimating the genetic diversity could define their usefulness in plant breeding programs. In this study, a total of 18 morphological traits and 20 simple sequence repeat (SSR) loci were used to study the morphological and genetic diversity among 20 maize hybrids selected from different countries, and to classify the hybrids into groups based on molecular profiles...
متن کاملP-121: Which Developmental Stage is Suitable for Re-vitrification? Compact Stage Re-vitrification or Early Blastocyst Stage Re-vitrification
Background: The aim of this study was evaluation of developmental rate and Bax, Bcl-2 and ErbB4 genes expression following re-vitrification in compact and early blastocysts stages. Materials and Methods: 5-8 cell embryos were collected from female mature mice, 60-62 hours post hCG injection. The embryos were divided to five groups including: fresh, vitrified at 5-8 cells, vitrified at blastocys...
