ZYGOTENE 1 (ZYGO1) was found in rice to participate in the construction of chromosomal morphology in the even-wire period

During the subtranslation splitting even-line period, chromosomes are curled together so that all chromosome telomeres congregate on the inside of the nuclear membrane, forming a specific telomere bouquet structure.
form of this chromosome, which plays an important role in the process of heogenic chromosomal pairing and subsequent subtranstation division as a highly conservative minus splitting event.
recent years, a number of important factors involved in telomere bouquet formation have been isolated between yeast and mammals, but these factors are not conservative among different species.
, the molecular mechanism of the formation of even-line chromosomes in plants is not clear.
, Cheng Zhuguang of the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences, discovered a new factor ZYGOTENE 1 (ZYGO1) in rice involved in the construction of even-wire chromosome morphology.
zygo1 mutants, even-wire chromosomes cannot be aggregated, scattered throughout the nucleuter, and telomere bouquets cannot be formed.
therefore, the appearance of the even period is not observed throughout the subtrament split period, which is represented as a mutant without an even period.
ZYGO1 mutation affects the polarization of OsSAD1 in the nuclear membrane, and is built by chromosomal morphology controlled by ZYGO1, independent of a series of important events such as DSB formation and repair.
the chromosomal morphology of the even-line period cannot be completed correctly, it has an effect on subsequent congener chromosome pairing, association and exchange.
ZYGO1 encodes a new F-box protein, which is interoperable through its F-box domain and OSK1 protein, indicating that ZYGO1, as a component of the SCF complex, regulates the morphology of even-wire chromosomes.
research has laid the foundation for the in-depth disclosure of the molecular mechanism of the chromosomal form of the minus split even-line period.
the study was published online in the journal Plant Cell.
research work has been funded by the Ministry of Science and Technology, the National Natural Science Foundation of China, etc.
