Comparative Small RNA Analysis of Pollen Development in Autotetraploid and Diploid Rice
MicroRNAs (miRNAs) play key roles in plant reproduction. However, knowledge on microRNAome analysis in autotetraploid rice is rather limited. Here, high-throughput sequencing technology was employed to analyze miRNAomes during pollen development in diploid and polyploid rice. A total of 172 differentially expressed miRNAs (DEM) were detected in autotetraploid rice compared to its diploid counte...
متن کاملNiche divergence between diploid and autotetraploid Tolmiea.
PREMISE OF STUDY Polyploidy is common in eukaryotes and is of major evolutionary importance over both short and long time-scales. Compared to allopolyploids, autopolyploids remain understudied; they are often morphologically cryptic and frequently remain taxonomically unrecognized, although there is increasing recognition of the high frequency of autopolyploidy in angiosperms. While autopolyplo...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Selection for phenotypic divergence between diploid and autotetraploid Heuchera grossulariifolia.
Much of the diversity of flowering plants is associated with genomic duplication through polyploidy. Little is known, however, about the evolutionary mechanisms responsible for the diversification of novel polyploid lineages. We evaluated the possibility that divergence is driven by natural selection by estimating the strength of phenotypic selection acting on three floral traits in sympatric p...
متن کاملOppositional Allelism in Diploid and Autotetraploid Trifolium Hybridum L.
HE selfand cross-incompatibilities of a number of obligately cross-polliT nated species of flowering plants are genetically determined by series of multiple oppositional alleles. The oppositional or personate incompatibility system was first described, with substantiating data, by EAST and MANGELSDORF (1925) for Nicotiana species. The existence of oppositional alleles has been subsequently demo...
