| 2 | Thermal-responsive genetic and epigenetic regulation of DAM cluster controlling dormancy and chilling requirement in peach floral buds显示文摘The Dormancy-associated MADS-box(DAM)gene cluster in peach serves as a key regulatory hub on which the seasonal temperatures act and orchestrate dormancy onset and exit,chilling response and floral bud developmental pace.Yet,how different temperature regimes interact with and regulate the six linked DAM genes remains unclear.Here,we demonstrate that chilling downregulates DAM1 and DAM3–6 in dormant floral buds with distinct patterns and identify DAM4 as the most abundantly expressed one.We reveal multiple epigenetic events,with tri-methyl histone H3 lysine 27(H3K27me3)induced by chilling specifically in DAM1 and DAM5,a 21-nt sRNA in DAM3 and a ncRNA induced in DAM4.Such induction is inversely correlated with downregulation of their cognate DAMs.We also show that the six DAMs were hypermethylated,associating with the production of 24-nt sRNAs.Hence,the chilling-responsive dynamic of the different epigenetic elements and their interactions likely define distinct expression abundance and downregulation pattern of each DAM.We further show that the expression of the five DAMs remains steadily unchanged or continuously downregulated at the ensuing warm temperature after chilling,and this state of regulation correlates with robust increase of sRNA expression,H3K27me3 and CHH methylation,which is particularly pronounced in DAM4.Such robust increase of repressive epigenetic marks may irreversibly reinforce the chillingimposed repression of DAMs to ensure flower-developmental programming free from any residual DAM inhibition.Taken together,we reveal novel information about genetic and epigenetic regulation of the DAM cluster in peach,which will be of fundamental significance in understanding of the regulatory mechanisms underlying chilling requirement and dormancy release,and of practical application for improvement of plasticity of flower time and bud break in fruit trees to adapt changing climates. | Hong Zhu Pao-Yang Chen Silin Zhong Chris Dardick Ann Callahan Yong-Qiang An Steve van Knocker Yingzhen Yang Gan-Yuan Zhong Albert Abbott Zongrang Liu | 2020 | Horticulture Research2020，7，1： | 9 |
| 3 | Genetic characterization of worldwide Prunus domestica(plum)germplasm using sequence-based genotyping显示文摘Prunus domestica commonly known as European plum is a hexaploid fruit tree species cultivated around the world.Locally it is used for fresh consumption,in jams or jellies,and the production of spirits while commercially the fruit is primarily sold dried(prunes).Despite its agricultural importance and long history of cultivation,many questions remain about the origin of this species,the relationships among its many pomological types,and its underlying genetics.Here,we used a sequence-based genotyping approach to characterize worldwide plum germplasm including the potential progenitor Eurasian plum species.Analysis of 405 DNA samples established a set of four clades consistent with the pomological groups Greengages,Mirabelles,European plums,and d’Agen(French)prune plums.A number of cultivars from each clade were identified as likely clonal selections,particularly among the“French”type prune germplasm that is widely cultivated today.Overall,there was relatively low genetic diversity across all cultivated plums suggesting they have been largely inbred and/or derived from a limited number of founders.The results agree with P.domestica having originated as an interspecific hybrid of a diploid P.cerasifera and a tetraploid P.spinosa that itself may have been an interspecific hybrid of P.cerasifera and an unknown Eurasian plum species.The low genetic diversity and lack of true wild-types coupled with the known cultivation history of Eurasian plums imply that P.domestica may have been a product of inter-specific cross breeding and artificial selection by early agrarian Eurasian societies. | Tetyana Zhebentyayeva Vijay Shankar Ralph Scorza Ann Callahan Michel Ravelonandro Sarah Castro Theodore DeJong Christopher A.Saski Chris Dardick | 2019 | Horticulture Research2019，6，1： | 4 |
| 4 | Identification of phloem-associated translatome alterations during leaf development in Prunus domestica L.显示文摘Phloem plays a fundamental role in plants by transporting hormones,nutrients,proteins,RNAs,and carbohydrates essential for plant growth and development.However,the identity of the underlying phloem genes and pathways remain enigmatic especially in agriculturally important perennial crops,in part,due to the technical difficulty of phloem sampling.Here,we used two phloem-specific promoters and a translating ribosome affinity purification(TRAP)strategy to characterize the phloem translatome during leaf development at 2,4,and 6 weeks post vernalization in plum(Prunus domestica L.).Results provide insight into the changing phloem processes that occur during leaf development.These processes included the early activation of DNA replication genes that are likely involved in phloem cell division during leaf expansion,as well as the upregulation of phloem genes associated with sink to source conversion,induction of defense processes,and signaling for reproduction.Combined these results reveal the dynamics of phloem gene expression during leaf development and establish the TRAP system as a powerful tool for studying phloem-specific functions and responses in trees. | Tamara D.Collum Elizabeth Lutton C.Douglas Raines Christopher Dardick James N.Culver | 2019 | Horticulture Research2019，6，1： | 2 |
| 5 | Alteration of TAC1 expression in Prunus species leads to pleiotropic shoot phenotypes显示文摘Prunus persica(peach)trees carrying the“Pillar”or“Broomy”trait(br)have vertically oriented branches caused by loss-of-function mutations in a gene called TILLER ANGLE CONTROL 1(TAC1).TAC1 encodes a protein in the IGT gene family that includes LAZY1 and DEEPER ROOTING 1(DRO1),which regulate lateral branch and root orientations,respectively.Here we found that some of the native TAC1 alleles in the hexaploid plum species Prunus domestica,which has a naturally more upright stature,contained a variable length trinucleotide repeat within the same exon 3 region previously found to be disrupted in pillar peach trees.RNAi silencing of TAC1 in plum resulted in trees with severely vertical branch orientations similar to those in pillar peaches but with an even narrower profile.In contrast,PpeTAC1 overexpression in plum led to trees with wider branch angles and more horizontal branch orientations.Pillar peach trees and transgenic plum lines exhibited pleiotropic phenotypes,including differences in trunk and branch diameter,stem growth,and twisting branch phenotypes.Expression profiling of pillar peach trees revealed differential expression of numerous genes associated with biotic and abiotic stress,hormone responses,plastids,reactive oxygen,secondary,and cell wall metabolism.Collectively,the data provide important clues for understanding TAC1 function and show that alteration of TAC1 expression may have broad applicability to agricultural and ornamental tree industries. | Courtney A.Hollender Jessica M.Waite Amy Tabb Doug Raines Srinivasan Chinnithambi Chris Dardick | 2018 | Horticulture Research2018，5，1： | 2 |
