| 1 | Feedback Regulation of FLC by FLOWERING LOCUS T (FT) and FD through a 5’ FLC Promoter Region in Arabidopsis显示文摘Dear Editor, Recently, it was reported that the florigenic FT protein bound to a 3’ region of the potent floral repressor FLC (FLOWERING LOCUS C) to activate the expression of long noncoding antisense RNAs known as COOLAIR and consequently repress FLC expression to control flowering time and seed dormancy in Arabidopsis (Chen and Penfield, 2018). Here, we show that FT represses FLC expression through a 5' promoter region, but not COOLAIR. | Xiao Luo Tao Chen Xiaolin Zeng Dingwei He Yuehui He | 2019 | Molecular Plant2019，12，3： | 10 |
| 2 | Genetic analysis and fine mapping of the pubescence gene GL6 in rice (Oryza sativa L.)显示文摘The pubescence of the leaf blade surface is an important agronomic characteristic for rice morphology and significantly influences rice growth as well as physiological characteristics. This characteristic was analyzed in F1 and F2 plants derived by crossing cultivar 75-1-127 with the indica cultivar Minghui 63, as well as the glabrous cultivar Lemont and indica cultivar 9311. Results indicated that the pubescence of the leaf blade surface was a dominant trait and controlled by a single gene. The GL6 gene was primarily mapped on rice chromosome 6 with recessive F2 population derived from 75-1-127/Minghui 63 by combining bulked segregation analysis and recessive class analysis using the Mapmaker3.0/MapDraw software. The genetic distances between the simple sequence repeat markers RM20491 and RM20547 were 7.2 and 2.2 cM, respectively. The GL6 gene was fine mapped in the interval between InDel-106 and InDel-115 at genetic distances of 0.3 and 0.1 cM, respectively. The large, recessive F2 population was derived from 75-1-127/Minghui 63. A high-resolution genetic and physical map of GL6 was constructed. Derived from the map-based sequences published by the International Rice Genome Sequencing Project, the GL6 gene was localized at an interval of 79 (japonica) and 116.82 kb (9311) bracketed by InDel-106 and InDel-115 within the BAC accession numbers AP008403 and AP005760. Seven annotated genes (japonica) and eight annotated genes (9311) were present. The basis was further set for GL6 cloning and function analysis. | ZENG YueHui ZHU YongSheng LIAN Ling XIE HongGuang ZHANG JianFu XIE HuaAn | 2013 | Chinese Science Bulletin2013，58，24： | 6 |
| 3 | Molecular basis of CONSTANS oligomerization in FLOWERING LOCUS T activation显示文摘The transcription factor CONSTANS(CO)integrates day-length information to induce the expression of florigen FLOWERING LOCUS T(FT)in Arabidopsis.We recently reported that the C-terminal CCT domain of CO forms a complex with NUCLEAR FACTOR-YB/YC to recognize multiple cis-elements in the FT promoter,and the N-terminal tandem B-box domains form a homomultimeric assembly.However,the mechanism and biological function of CO multimerization remained unclear.Here,we report that CO takes on a head-to-tail oligomeric configuration via its B-boxes to mediate FT activation in long days.The crystal structure of B-boxesCOreveals a closely connected tandem B-box fold forming a continuous head-to-tail assembly through unique CDHH zinc fingers.Mutating the key residues involved in CO oligomerization resulted in a non-functional CO,as evidenced by the inability to rescue co mutants.By contrast,a transgene encoding a human p53-derived tetrameric peptide in place of the B-boxesCOrescued co mutant,emphasizing the essential role of BboxesCO-mediated oligomerization.Furthermore,we found that the four TGTG-bearing cis-elements in FT proximal promoter are required for FT activation in long days.Our results suggest that CO forms a multimer to bind to the four TGTG motifs in the FT promoter to mediate FT activation. | Xiaolin Zeng Xinchen Lv Rui Liu Hang He Shiqi Liang Lixian Chen Fan Zhang Liu Chen Yuehui He Jiamu Du | 2022 | Journal of Integrative Plant Biology2022，64，3： | 2 |
| 4 | Genetic and Epigenetic Understanding of the Seasonal Timing of Flowering显示文摘The developmental transition to flowering in many plants is timed by changing seasons,which enables plants to flower at a season that is favorable for seed production.Many plants grown at high latitudes perceive the seasonal cues of changing day length and/or winter cold(prolonged cold exposure),to regulate the expression of flowering-regulatory genes through the photoperiod pathway and/or vernalization pathway,and thus align flowering with a particular season.Recent studies in the model flowering plant Arabidopsis thaliana have revealed that diverse transcription factors engage various chromatin modifiers to regulate several key flowering-regulatory genes including FLOWERING LOCUS C(FLC)and FLOWERING LOCUS T(FT)in response to seasonal signals.Here,we summarize the current understanding of molecular and chromatin-regulatory or epigenetic mechanisms underlying the vernalization response and photoperiodic control of flowering in Arabidopsis.Moreover,the conservation and divergence of regulatory mechanisms for seasonal flowering in crops and other plants are briefly discussed. | Yuehui He Tao Chen Xiaolin Zeng | 2020 | Plant Communications2020，1，1： | 2 |
