在长期进化过程中,大豆基因组经历了两次复制事件,约75%的基因都存在多拷贝,大豆共有四个TERMINAL FLOWER 1(TFL1)基因TFL1a、TFL1b、TFL1c和TFL1d,其中TFL1b(Dt1)被认为是参与大豆结荚习性调控的重要基因,同时也参与调控大豆开花。但大豆中其他TFL1同源基因的功能尚不清楚。近日,广州大学刘宝辉/孔凡江团队在The Cr...
Generation of mobile TFL1 in the chalazal endosperm, which is close to maternal vascular tissues, could provide a hitherto-unknown means to control seed development by mother plants. TERMINAL FLOWER1 (TFL1) is key factor that controls flowering time and inflorescence meristem identity. Here, the...
Plants monitor seasonal cues to optimize reproductive success by tuning onset of reproduction and inflorescence architecture. TERMINAL FLOWER 1 (TFL1) and FLOWERING LOCUS T (FT) and their orthologs antagonistically regulate these life history traits, yet their mechanism of action, antagonism and targets...

TERMINAL FLOWER 1 (TFL1) is known to be involved in the transcriptional repression of genes for inflorescence development. Two TFL1 transcripts with different 3' UTR were cloned from black cherry (Prunus serotina Ehrh.) using reverse transcription-polymerase chain reaction (RT-PCR) and rapid ...
TERMINAL FLOWER1 (TFL1) is a key regulator of flowering time and the development of the inflorescence meristem in Arabidopsis thaliana. TFL1 and FLOWERING LOCUS T (FT) have highly conserved amino acid sequences but opposite functions. For example, FT promotes flowering and TFL1 represses it; ...
In plant development, the flowering transition and inflorescence architecture are modulated by two homologous proteins, FLOWERING LOCUS T (FT) and TERMINAL FLOWER 1 (TFL1). The florigen FT promotes the transition to reproductive development and flowering, while TFL1 represses this transition. Despite ...
(Kardailsky et al.1999; Tsuji and Taoka2014; Tsuji2017). InArabidopsis, TERMINAL FLOWER 1 (TFL1) of the FT/TFL1 family of proteins has been identified as a local floral inhibitor expressed in the SAM (Shannon and Meeks-Wagner1991; Bradley et al.1997). FT/TFL1 encodes a pair of ...
在这里,我们报道了拟南芥终端花1 (TFL1)是在合点胚乳中产生的一种可移动调节因子,它通过稳定脱落酸不敏感5(ABSCISIC ACIDINSENSITIVE 5)而移动到合胞外周胚乳中,及时介导胚乳纤维素化和种子大小。我们进一步证明,ras相关的核GTPases与TFL1相互作用,并调节其转运到合胞体外周胚乳。我们的研究结果表明,TFL1是调控...
植物FLOWERING LOCUS T/TERMlNAL FLOWERl(FT/TFLl)基因家族是一个进化上高度保守的基因家族,它在植物的花发育过程中具有重要作用:其成员FT基因编码的蛋白产物是可以长距离转运的成花激素,在花形成过程中起关键作用,另一成员TFL1基因则在花序的形成和维持过程中起重要作用.本文就近年来国内外对植物FT/TFL1基因家族...
