Compartmentalization of S-RNase and HT-B degradation in self-incompatible Nicotiana
TLDR
It is suggested that S-RNase trafficking and the stability of HT-B are central to S-specific pollen rejection.
Phylogeny of the sundews, Drosera (Droseraceae), based on chloroplast rbcL and nuclear 18S ribosomal DNA Sequences.
TLDR
Preliminary phylogenetic analyses of DNA sequences of the chloroplast rbcL gene for 59 species of Drosera revealed that all DroserA species form a clade sister to aClade including Dionaea and Aldrovanda, suggesting that the snap traps of Aldrovandas and Dionaea are homologous despite their morphological differences.
Molecular analysis of the stylar-expressed Solanum chacoense small asparagine-rich protein family related to the HT modifier of gametophytic self-incompatibility in Nicotiana.
TLDR
The isolation and characterization of two Solanum chacoense homologues of the Nicotiana HT modifier are presented and results confirm the role of the HT modifier in solanaceous SI and indicate that only the HT-B isoform is directly involved in SI.
Insights into the evolution of self-compatibility in Lycopersicon from a study of stylar factors.
TLDR
The results argue for several independent mutations in the S-RNase gene over the course of Lycopersicon diversification, and that loss of S- RNase function is unlikely to be the primary cause of the loss of self-incompatibility.
Multiple features that distinguish unilateral incongruity and self-incompatibility in the tomato clade.
TLDR
There are significant differences between SI and UI in the tomato clade, in that pollen tube growth differs between these two rejection systems, and some stylar SI factors, including S-RNase and HT-B, are not required for UI.
DIFFERENTIAL STAINING WITH ORCEIN, GIEMSA, CMA, AND DAPI FOR COMPARATIVE CHROMOSOME STUDY OF 12 SPECIES OF AUSTRALIAN DROSERA (DROSERACEAE)'
TLDR
Differential stainings with orcein, Giemsa, CMA, and DAPI were compared in 12 species of Western Australian Drosera and it is suggested that D. helodes and D. sewelliae are closely related.
Cultivated tomato has defects in both S-RNase and HT genes required for stylar function of self-incompatibility.
TLDR
The results suggest that the breakdown of self-incompatibility in cultivated tomato is associated with loss-of-function mutations in both S-RNase and HT genes.
A natural variant of NAL1, selected in high-yield rice breeding programs, pleiotropically increases photosynthesis rate
TLDR
It is shown that the quantitative trait locus GPS (GREEN for PHOTOSYNTHESIS) in rice (Oryza sativa L.) controls photosynthesis rate by regulating carboxylation efficiency.
Unmasking Novel Loci for Internal Phosphorus Utilization Efficiency in Rice Germplasm through Genome-Wide Association Analysis
TLDR
The loci reported here are the first identified for PUE in any crop that is not confounded by differential P uptake among genotypes, and would thus benefit from targeted introgressions of these loci from traditional donors to improve plant growth in phosphorus-limited cropping systems.
