Genome-Wide Identification and Characterization of Annexin Gene Family in Vitis vinifera and Functional Analysis of VvANN8 Under Salt Stress.

Grapes are economically significant fruit trees cultivated globally, but they are often affected by various abiotic stresses. Plant annexins are a class of calcium-dependent phospholipid-binding proteins that play crucial roles in regulating plant growth, development, and stress responses. However, the functions of grape annexins (VvANNs) remain relatively poorly understood.

MdDSK2a-Like-MdMTA Module Functions in Apple Cold Response via Regulating ROS Detoxification and Cell Wall Deposition.

N-methyladenosine (mA) is the most abundant internal RNA modification in eukaryotic cells. Although the importance of its roles in mRNA metabolism, plant development, and stress responses has been well documented, regulation of its machinery is largely unknown in plants. Here, it is reported that MdMTA positively regulates cold tolerance.

Genome-Wide Identification of the Gene Family in Kiwifruit () and Functional Validation of in Response to Drought Stress.

DNA-binding one zinc finger (DOF) transcription factors are crucial plant-specific regulators involved in growth, development, signal transduction, and abiotic stress response generation. However, the genome-wide identification and characterization of genes and their regulatory elements in kiwifruit () has not been thoroughly investigated. In this study, we screened the kiwifruit genome database and identified 42 genes ( to ).

MdMTA-mediated m A modification enhances drought tolerance by promoting mRNA stability and translation efficiency of genes involved in lignin deposition and oxidative stress.

Although the N -methyladenosine (m A) modification is the most prevalent RNA modification in eukaryotes, the global m A modification landscape and its molecular regulatory mechanism in response to drought stress remain unclear. Transcriptome-wide m A methylome profiling revealed that m A is mainly enriched in the coding sequence and 3' untranslated region in response to drought stress in apple, by recognizing the plant-specific sequence motif UGUAH (H=A, U or C). We identified a catalytically active component of the m A methyltransferase complex, MdMTA.

Cold shock protein 3 plays a negative role in apple drought tolerance by regulating oxidative stress response.

As RNA chaperones, cold shock proteins (CSPs) are essential for cold adaptation. Although the functions of CSPs in cold response have been demonstrated in several species, the roles of CSPs in response to drought are largely unknown. Here, we demonstrated that MdCSP3, a downstream target gene of MdMYB88 and MdMYB124, contributes to drought tolerance in apple (Malus × domestica).

A multifaceted module of BRI1 ETHYLMETHANE SULFONATE SUPRESSOR1 (BES1)-MYB88 in growth and stress tolerance of apple.

The R2R3 transcription factor MdMYB88 has previously been reported to function in biotic and abiotic stress responses. Here, we identify BRI1 ETHYLMETHANE SULFONATE SUPRESSOR1 (MdBES1), a vital component of brassinosteroid (BR) signaling in apple (Malus × domestica) that directly binds to the MdMYB88 promoter, regulating the expression of MdMYB88 in a dynamic and multifaceted mode. MdBES1 positively regulated expression of MdMYB88 under cold stress and pathogen attack, but negatively regulated its expression under control and drought conditions.

FISH-based mitotic and meiotic diakinesis karyotypes of Morus notabilis reveal a chromosomal fusion-fission cycle between mitotic and meiotic phases.

Mulberry (Morus spp.), in family Moraceae, is a plant with important economic value. Many polyploid levels of mulberry have been determined.
