Genomic variation in 3,010 diverse accessions of Asian cultivated rice
Analyses of genetic variation and population structure based on over 3,000 cultivated rice (Oryza sativa) genomes reveal subpopulations that correlate with geographic location and patterns of introgression consistent with multiple rice domestication events.
EAT1 promotes tapetal cell death by regulating aspartic proteases during male reproductive development in rice.
It is demonstrated that ETERNAL TAPETUM 1 promotes aspartic proteases triggering plant programmed cell death, and reveals a dynamic regulatory cascade in male reproductive development in rice.
The ABORTED MICROSPORES Regulatory Network Is Required for Postmeiotic Male Reproductive Development in Arabidopsis thaliana[W][OA]
It is shown by microarray analysis that the expression of 549 anther-expressed genes was altered in ams buds and that these genes are associated with tapetal function and pollen wall formation, and it is demonstrated that AMS has the ability to bind in vitro to DNA containing a 6-bp consensus motif, CANNTG.
Cytochrome P450 Family Member CYP704B2 Catalyzes the ω -Hydroxylation of Fatty Acids and Is Required for Anther Cutin Biosynthesis and Pollen Exine Formation in Rice[W][OA]
This study indicates that the ω -hydroxylation pathway of fatty acids relying on this ancient CYP704B family, conserved from moss to angiosperms, is essential for the formation of both cuticle and exine during plant male reproductive and spore development.
PERSISTENT TAPETAL CELL1 Encodes a PHD-Finger Protein That Is Required for Tapetal Cell Death and Pollen Development in Rice1[C][W][OA]
A diversified and conserved switch of PTC1/MS1 in regulating programmed male reproductive development in both dicots and monocots is suggested, which provides new insights in plant anther development.
Genome-Wide Analysis of Basic/Helix-Loop-Helix Transcription Factor Family in Rice and Arabidopsis1[W]
The genome distribution of rice b HLH genes strongly supports the hypothesis that genome-wide and tandem duplication contributed to the expansion of the bHLH gene family, consistent with the birth-and-death theory of gene family evolution.

OsC6 plays a crucial role in the development of lipidic orbicules and pollen exine during anther development in rice, and additional evidence is provided that the expression of OsC6 is positively regulated by a basic helix-loop-helix transcription factor, Tapetum Degeneration Retardation (TDR).
Rice MADS3 Regulates ROS Homeostasis during Late Anther Development[W][OA]
It is suggested that MADS3 is a key transcriptional regulator that functions in rice male reproductive development, at least in part, by modulating ROS levels through MT-1-4b.
The FLORAL ORGAN NUMBER4 Gene Encoding a Putative Ortholog of Arabidopsis CLAVATA3 Regulates Apical Meristem Size in Rice1[W]
The isolation and characterization of three floral organ number4 (fon4) alleles and the cloning of the FON4 gene revealed it encodes a small putatively secreted protein, which is the putative ortholog of the Arabidopsis (Arabidopsis thaliana) CLAVATA3 (CLV3) gene.
Defective Pollen Wall Is Required for Anther and Microspore Development in Rice and Encodes a Fatty Acyl Carrier Protein Reductase[C][W][OA]
The isolation and characterization of a rice male-sterile mutant, defective pollen wall, and demonstrate that the monocot DPW from rice complements the dicot Arabidopsis thaliana male sterile2 and is the probable ortholog of MS2, suggest that DPWs participate in a conserved step in primary fatty alcohol synthesis for anther cuticle and pollen sporopollenin biosynthesis in monocots and dicots.
