The Rice Tapetum Degeneration Retardation Gene Is Required for Tapetum Degradation and Anther Development[W]
TLDR
Results indicate that TDR is a key component of the molecular network regulating rice tapetum development and degeneration, and two genes, Os CP1 and Os c6, encoding a Cys protease and a protease inhibitor, were shown to be the likely direct targets of TDR. Expand
Genome-Wide Analysis of Basic/Helix-Loop-Helix Transcription Factor Family in Rice and Arabidopsis1[W]
TLDR
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. Expand
PERSISTENT TAPETAL CELL1 Encodes a PHD-Finger Protein That Is Required for Tapetal Cell Death and Pollen Development in Rice1[C][W][OA]
TLDR
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. Expand
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]
TLDR
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. Expand
EAT1 promotes tapetal cell death by regulating aspartic proteases during male reproductive development in rice.
TLDR
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. Expand
The ABORTED MICROSPORES Regulatory Network Is Required for Postmeiotic Male Reproductive Development in Arabidopsis thaliana[W][OA]
TLDR
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. Expand
OsC6, Encoding a Lipid Transfer Protein, Is Required for Postmeiotic Anther Development In Rice1[W][OA]
TLDR
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). Expand
The FLORAL ORGAN NUMBER4 Gene Encoding a Putative Ortholog of Arabidopsis CLAVATA3 Regulates Apical Meristem Size in Rice1[W]
TLDR
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. Expand
Defective Pollen Wall Is Required for Anther and Microspore Development in Rice and Encodes a Fatty Acyl Carrier Protein Reductase[C][W][OA]
TLDR
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. Expand
Genome-wide analysis of plant nat-siRNAs reveals insights into their distribution, biogenesis and function
TLDR
The results suggest that nat-siRNAs display distinct distribution patterns and are generated by DCL1 and/or DCL3, and the levels of some nat-SIRNAs were regulated by specific biotic or abiotic stress conditions in Arabidopsis and rice. Expand
