  • Key message
    • The suppressed telomere clustering in homologous pairing aberration in rice meiosis 1 (pair1) zygo1 and rice completion of meiotic recombination (Oscom1) zygo1 double mutants, together with the altered localization of OsSAD1 (a SUN protein associated with the nuclear envelope) in zygo1 showed that ZYGO1 has a significant function in bouquet formation
    • Therefore, we propose that ZYGO1 mediates bouquet formation to efficiently promote homolog pairing, synapsis, and CO formation in rice meiosis
    • Furthermore, crossover (CO) formation was disturbed, and foci of Human enhancer of invasion 10 (HEI10) were restricted to the partially-synapsed chromosome regions, indicating that CO reduction might be caused by the failure of full-length chromosome alignment in zygo1

    • Virus-induced gene silencing of a ZN homolog in Nicotiana benthamiana causes leaf variegation with sporadic green/yellow sectors, indicating that ZN is essential for chloroplast biogenesis during early leaf development
    • Together, we propose that ZN is required for protecting developing chloroplasts, especially during the assembly of thylakoid protein complexes, from incidental light after darkness

  • Information
  • Publication
  • Genbank accession number
  • Key message
    • We previously identified a salt and drought stress-responsive TFIIIA-type zinc finger protein gene ZFP252 from rice
    • We found that overexpression of ZFP252 in rice increased the amount of free proline and soluble sugars, elevated the expression of stress defense genes and enhanced rice tolerance to salt and drought stresses, as compared with ZFP252 antisense and non-transgenic plants
    • Our findings suggest that ZFP252 plays an important role in rice response to salt and drought stresses and is useful in engineering crop plants with enhanced tolerance to salt and drought stresses
    • Overexpression of a TFIIIA-type zinc finger protein gene ZFP252 enhances drought and salt tolerance in rice (Oryza sativa L.)
    • These results indicated that the RZF71 may play an important role in rice responses to salt and osmotic stresses as a transcription factor
    • The semi-quantitative RT-PCR assay showed RZF71 was strongly induced by high-salinity and 20% PEG6000 treatments, but not regulated by low temperature and ABA (abscisic acid) treatments
    • The expression profiling showed that RZF71 was constitutively expressed in roots, culms, leaves, and flowering spikes
    • A rice zinc-finger protein gene, RZF71, encoding the C2H2-type zinc-finger transcription factor was isolated from rice

  • Information
  • Publication
  • Genbank accession number
  • Key message
    • Overproduction of ZFP245 enhanced the activities of reactive oxygen species-scavenging enzymes under stress conditions and increased the tolerance of rice seedlings to oxidative stress
    • However, ZFP245 was not regulated by high salt or abscisic acid treatment
    • The semi-quantitative-RT-PCR assay revealed ZFP245 was strongly induced after 6 h exposure to cold and drought stresses, and then reduced to the baseline
    • Taken together, ZFP245, as the first identified C2H2-type zinc finger protein involved in stress response in monocots probably plays a role as a transcription regulator in plant cold and drought responses through an ABA-independent pathway
    • A C2H2-type zinc finger protein gene ZFP245 was cloned by RT-PCR approach from cold treated rice seedlings
    • Our data suggest that ZFP245 may contribute to the tolerance of rice plants to cold and drought stresses by regulating proline levels and reactive oxygen species-scavenging activities, and therefore may be useful for developing transgenic crops with enhanced tolerance to abiotic stress
    • ZFP245 is a cold- and drought-responsive gene that encodes a zinc finger protein in rice
    • Transgenic rice plants overexpressing ZFP245 were generated and found to display high tolerance to cold and drought stresses
    • Increased tolerance of rice to cold, drought and oxidative stresses mediated by the overexpression of a gene that encodes the zinc finger protein ZFP245
    • Tissue expression analysis showed that ZFP245 was constitutively expressed in various rice tissues including roots, stems, leaves and spikes

  • Information
  • Publication
  • Genbank accession number

  • Key message
    • Here we report a novel A20/AN1-type zinc finger protein ZFP185 involved in GA and ABA signaling in the regulation of growth and stress response
    • Our study suggests that ZFP185 regulates plant growth and stress responses by affecting GA and ABA biosynthesis in rice
    • Moreover, it was found that ZFP185, unlike previously known A20/AN1-type zinc finger genes, increases sensitivity to drought, cold, and salt stresses, implying the negative role of ZFP185 in stress tolerance
    • Besides GA, overexpression of ZFP185 decreased ABA content and expression of several ABA biosynthesis-related genes
    • The application of exogenous GA3 can fully rescue the semi-dwarfism phenotype of ZFP185 overexpressing plants, suggesting the negative role of ZFP185 in GA biosynthesis
    • ZFP185 was localized in the cytoplasm and lacked transcriptional activation potential

  • Information
  • Publication
  • Genbank accession number
  • Key message
    • Overexpression of ZFP182 significantly enhanced multiple abiotic stress tolerances, including salt, cold and drought tolerances in transgenic rice
    • The expression analysis showed that ZFP182 gene was constitutively expressed in leaves, culms, roots and spikes at the adult rice plants, and markedly induced in the seedlings by cold (4 degrees C), 150 mM NaCl and 0
    • Nipponbare) C(2) H(2) -type ZFP ZFP182 in ABA-induced antioxidant defense and the relationship between ZFP182 and two rice MAPKs, OsMPK1 and OsMPK5 in ABA signaling were investigated
    • These results indicate that ZFP182 is required for ABA-induced antioxidant defense and the expression of ZFP182 is regulated by rice MAPKs in ABA signaling
    • The C2H2-type zinc finger protein ZFP182 is involved in abscisic acid-induced antioxidant defense in rice
    • Expression of ZFP182 in transgenic tobacco and overexpression in rice increased plant tolerance to salt stress
    • These results demonstrated that ZFP182 might be involved in plant responses to salt stress
    • ABA treatment induced the increases in the expression of ZFP182, OsMPK1 and OsMPK5, and the activities of superoxide dismutase (SOD) and ascorbate peroxidase (APX) in rice leaves
    • Besides, OsMPK1 and OsMPK5 were shown to be required for the up-regulation in the expression of ZFP182 in ABA signaling, but ZFP182 did not mediate the ABA-induced up-regulation in the expression of OsMPK1 and OsMPK5

    • The ZFP179 transgenic rice exhibited significantly increased tolerance to oxidative stress, the reactive oxygen species (ROS)-scavenging ability, and expression levels of a number of stress-related genes, including OsDREB2A, OsP5CS OsProT, and OsLea3 under salt stress
    • Our studies suggest that ZFP179 plays a crucial role in the plant response to salt stress, and is useful in developing transgenic crops with enhanced tolerance to salt stress
    • The real-time RT-PCR analysis showed that ZFP179 was highly expressed in immature spikes, and markedly induced in the seedlings by NaCl, PEG 6000, and ABA treatments
    • Through microarray analysis, a salt-responsive zinc finger protein gene ZFP179 was identified and subsequently cloned from rice seedlings
    • Overexpression of ZFP179 in rice increased salt tolerance and the transgenic seedlings showed hypersensitivity to exogenous ABA

  • Publication
  • Genbank accession number
  • Key message
    • These results suggested that ZFP177 might play crucial but differential roles in plant responses to various abiotic stresses
    • Through microarray analysis, it was found that four genes (ZFP177, ZFP181, ZFP176, ZFP173), two genes (ZFP181 and ZFP176) and one gene (ZFP157) were significantly induced by cold, drought and H(2)O(2) treatments, respectively
    • Overexpression of ZFP177 in tobacco conferred tolerance of transgenic plants to both low and high temperature stresses, but increased sensitivity to salt and drought stresses
    • Further expression analysis showed that ZFP177 was responsive to both cold and heat stresses, but down-regulated by salt
    • Expression analysis of rice A20/AN1-type zinc finger genes and characterization of ZFP177 that contributes to temperature stress tolerance
