| 1 | 2017年中国植物科学若干领域重要研究进展显示文摘2017年中国植物科学继续保持高速发展态势,重大成果频出,具体表现在中国植物学家在国际顶级学术期刊发表的文章数量平稳上升。中国植物科学领域的研究工作者成果精彩纷呈,如新型广谱抗病机制的发现、水稻广谱抗病遗传基础及机制和疫霉菌诱发病害成灾机制研究等。2017年中国生命科学领域十大进展评选中,有两项植物科学领域的研究成果入选。水稻生物学、进化与基因组学和激素生物学等领域学科发展突出。另外,值得一提的是,长期从事高等植物与代谢途径调控分子网络研究和水稻品种设计育种的李家洋院士的研究成果'水稻高产优质性状形成的分子机理及品种设计'荣获2017年国家自然科学一等奖。这一具有重大国际影响的开创性贡献标志着中国植物科学在该领域的国际科学前沿居于引领和卓越地位。该文对2017年中国本土科学家在植物科学若干领域取得的重要研究成果进行了系统梳理,旨在全面追踪和报道当前中国植物科学领域发展的最新前沿动态,与广大读者共同分享我国科学家所取得的辉煌成就。 | 陈凡 钱前 王台 董爱武 漆小泉 左建儒 杨淑华 林荣呈 萧浪涛 顾红雅 陈之端 姜里文 白永飞 孔宏智 种康 | 2018 | 植物学报2018，53，4： | 12 |
| 2 | VcFT-induced mobile florigenic signals in transgenic and transgrafted blueberries显示文摘FLOWERING LOCUS T(FT)can promote early flowering in annual species,but such role has not been well demonstrated in woody species.We produced self and reciprocal grafts involving non-transgenic blueberry(NT)and transgenic blueberry(T)carrying a 35S-driven blueberry FT(VcFT-OX).We demonstrated that the transgenic VcFT-OX rootstock promoted flowering of non-transgenic blueberry scions in the NT(scion):T(rootstock)grafts.We further analyzed RNASeq profiles and six groups of phytohormones in both NT:T and NT:NT plants.We observed content changes of several hormone metabolites,in a descending order,in the transgenic NT:T,non-transgenic NT:T,and non-transgenic NT:NT leaves.By comparing differential expression transcripts(DETs)of these tissues in relative to their control,we found that the non-transgenic NT:T leaves had many DETs shared with the transgenic NT:T leaves,but very few with the transgenic NT:T roots.Interestingly,a number of these shared DETs belong to hormone pathway genes,concurring with the content changes of hormone metabolites in both transgenic and non-transgenic leaves of the NT:T plants.These results suggest that phytohormones induced by VcFT-OX in the transgenic leaves might serve as part of the signals that resulted in early flowering in both transgenic plants and the non-transgenic NT:T scions. | Guo-qing Song Aaron Walworth Tianyi Lin Qiuxia Chen Xiumei Han LIrina Zaharia Gan-yuan Zhong | 2019 | Horticulture Research2019，6，1： | 3 |
| 3 | Candidate genes underlying QTL for flowering time and their interactions in a wide spring barley(Hordeum vulgare L.) cross显示文摘Response to vernalization and photoperiod are the main determinants controlling the time to flowering in temperate cereals. While the individual genes that determine a plant's response to these environmental signals are well characterized, the combinatorial effect on flowering time of allelic variants for multiple genes remains unresolved. This study investigated the genetic control of flowering-time in a biparental population of spring barley, derived from a wide cross between a late-flowering European and an early-flowering North-American cultivar. While the major flowering time genes are not segregating in the Beka ×Logan cross, large variation in flowering was observed. We identified five QTL, with both parents found to contribute early alleles. The catalog of QTL discovered aligns with several candidate genes affecting flowering time in barley. The combination of particular alleles at HvCEN, HvELF3 and HvFT1 in Logan are responsible for the earliness of this cultivar. Interestingly, earliness for flowering could be further enhanced, with Beka found to contribute three early alleles, including a QTL colocating with a HvFD-like gene, suggesting that there are diverse aspects of the flowering-time pathway that have been manipulated in these two cultivars. Epistatic interactions between flowering-time QTL or candidate genes were observed in field data and confirmed under controlled conditions. The results of this study link photoperiod-dependent flowering-time genes with earliness per se genes into a single model, thus providing a unique framework that can be used by geneticists and breeders to optimize flowering time in barley. | Ana M.Casas Carlota R.Gazulla Arantxa Monteagudo Carlos P.Cantalapiedra Marian Moralejo MPilar Gracia Francisco J.Ciudad William T.B.Thomas Jose L.Molina-Cano Scott Boden Bruno Contreras-Moreira Ernesto Igartua | 2021 | The Crop Journal2021，9，4： | 0 |
