During Arabidopsis seed development, the growing embryo invades and consumes the surrounding endosperm tissue. The signalling pathways that coordinate the separation of the embryo from the endosperm and the concomitant breakdown of the endosperm are poorly understood. We have identified a novel bHLH transcription factor, ZHOUPI (ZOU), which mediates these(More)
The Polycomb group (PcG) and trithorax group (trxG) genes play crucial roles in development by regulating expression of homeotic and other genes controlling cell fate. Both groups catalyse modifications of chromatin, particularly histone methylation, leading to epigenetic changes that affect gene activity. The trxG antagonizes the function of PcG genes by(More)
In Arabidopsis, mutations in the Pc-G gene CURLY LEAF (CLF) give early flowering plants with curled leaves. This phenotype is caused by mis-expression of the floral homeotic gene AGAMOUS (AG) in leaves, so that ag mutations largely suppress the clf phenotype. Here, we identify three mutations that suppress clf despite maintaining high AG expression. We show(More)
Soybean [Glycine max (L.) Merrill] is an important crop worldwide. In this study, a Chinese local soybean cultivar, Hedou 12, was resequenced by next generation sequencing technology to develop INsertion/DELetion (INDEL) markers for genetic mapping. 49,276 INDEL polymorphisms and 242,059 single nucleotide polymorphisms were detected between Hedou 12 and the(More)
Vegetative growth of Chinese cabbage undergoes the four successive stages which are characterized with the definite types of juvenile, rosette, folding and head leaves. From shoot tips of Chinese cabbage at early folding stage, we constructed a cDNA library and screened the differentially expressed cDNA clones using the cDNAs derived from developing folding(More)
Heteroblasty refers to the changes in leaf shape and size (allometry) along stems. Although evolutionary changes involving heteroblasty might contribute to leaf diversity, little is known of the extent to which heteroblasty differs between species or how it might relate to other aspects of allometry or other developmental transitions. Here, we develop a(More)
Ectopic expression of the MYB transcription factor of AmROSEA1 from Antirrhinum majus has been reported to change anthocyanin and other metabolites in several species. In this study, we found that overexpression of AmRosea1 significantly improved the tolerance of transgenic rice to drought and salinity stresses. Transcriptome analysis revealed that a(More)
Soybean (Glycine max Merr.) is the world's most widely grown legume and provides an important source of protein and oil. Improvement of seed quality requires deep insights into the genetic regulation of seed development. The endosperm serves as a temporary source of nutrients that are transported from maternal to filial tissues, and it also generates(More)
The seventh and eighth authors' names are spelled incorrectly. The correct names are: Flavia de Lima Alves and Juri Rappsilber. The following information is missing from the Funding section: The Wellcome Trust generously funded this work through a Senior Research Fellowship to JR (103139), a Centre core grant (092076) and an instrument grant (108504).(More)
Soybean (Glycine max) is one of the most important crops in the world, and its yield is largely determined by grain weight and grain size. However, the genes that regulate soybean seed size have not been identified. CYP78A, which is highly conserved within terrestrial plants, regulates organ development. In Arabidopsis, AtCYP78A5/KLU has been shown to(More)
