Rice NON-YELLOW COLORING1 Is Involved in Light-Harvesting Complex II and Grana Degradation during Leaf Senescence[W]
TLDR
The data collectively suggest that the identified SDR protein NYC1 plays essential roles in the regulation of LHCII and thylakoid membrane degradation during senescence. Expand
S Locus F-Box Brothers: Multiple and Pollen-Specific F-Box Genes With S Haplotype-Specific Polymorphisms in Apple and Japanese Pear
TLDR
The unique multiplicity of SFBB genes as the pollen S candidate is discussed in the context of mechanistic variation in the S-RNase-based GSI system. Expand
Self-Incompatibility in the Genus Arabidopsis: Characterization of the S Locus in the Outcrossing A. lyrata and Its Autogamous Relative A. thaliana
TLDR
Comparative mapping of the A. lyrata and Brassica S loci indicates that the S locus of crucifers is a dynamic locus that has undergone several duplication events since the Arabidopsis–Brassica split and was translocated as a unit between two distant chromosomal locations during diversification of the two taxa. Expand
Two short-chain dehydrogenase/reductases, NON-YELLOW COLORING 1 and NYC1-LIKE, are required for chlorophyll b and light-harvesting complex II degradation during senescence in rice.
TLDR
Analysis of the nyc1 mutant, which shows the stay-green phenotype, and the nol mutant in rice, suggest that NOL and NYC1 are co-localized in the thylakoid membrane and act in the form of a complex as a chlorophyll b reductase in rice. Expand
Genetic analysis of Nicotiana pollen-part mutants is consistent with the presence of an S-ribonuclease inhibitor at the S locus
TLDR
The absence of pollen S deletions in this study and perhaps other studies suggests that pollen S might be required for pollen viability, possibly because its product acts as an S-RNase inhibitor. Expand
Defect in non-yellow coloring 3, an alpha/beta hydrolase-fold family protein, causes a stay-green phenotype during leaf senescence in rice.
TLDR
A new stay-green mutant in rice, nyc3, which encodes a plastid-localizing alpha/beta hydrolase-fold family protein with an esterase/lipase motif and the possible function of NYC3 in the regulation of chlorophyll degradation is discussed. Expand
Striking sequence similarity in inter- and intra-specific comparisons of class I SLG alleles from Brassica oleracea and Brassica campestris: implications for the evolution and recognition mechanism.
TLDR
31 novel SLG sequences of Brassica oleracea and Brassica campestris are reported and it is suggested that SLG diversification predates speciation and that intragenic recombination has contributed to the generation of the high level of sequence variation in SLG alleles. Expand
Participation of Chlorophyll b Reductase in the Initial Step of the Degradation of Light-harvesting Chlorophyll a/b-Protein Complexes in Arabidopsis*
TLDR
It is reported that chlorophyll b reductase, which catalyzes the first step of chlorophyLL b degradation, plays a central role in LHCII degradation, and that trimeric L HCII is a substrate of LHC II degradation. Expand
Coevolution of the S-locus genes SRK, SLG and SP11/SCR in Brassica oleracea and B. rapa.
TLDR
It is found that three S haplotypes lacking SLG genes in B. rapa are found, confirming that SLG is not essential for the SI recognition system and operation of diversifying selection to maintain the diversity of these regions is suggested. Expand
Molecular characterization of mutations induced by gamma irradiation in rice.
TLDR
Reverse genetics applications may be possible for gamma irradiation-induced deletions in rice by mismatch cleavage analysis used in Targeting Induced Local Lesions IN Genomes (TILLING) to detect small deletions and base substitutions or by using array comparative genomic hybridization (aCGH), to detect large deletions.
