An APSES Transcription Factor Xbp1 Is Required for Sclerotial Development, Appressoria Formation, and Pathogenicity in .

Sclerotinia diseases are important plant fungal diseases that, causes huge economic worldwide losses every year. is the main pathogen that results in mulberry sclerotia diseases. Sclerotia and appressoria play important roles in long-term pathogen survival and in host infection during life and disease cycles.

The C-terminal tail of the plant endosomal-type NHXs plays a key role in its function and stability.

Typically, Na/H antiporters (NHXs) possess a conserved N-terminus for cation binding and exchange and a hydrophilic C-terminus for regulating the antiporter activity. Plant endosomal-type NHXs play important roles in protein trafficking, as well as K and vesicle pH homeostasis, however the role of the C-terminal tail remains unclear. Here, the function of MnNHX6, an endosomal-type NHX in mulberry, was investigated using heterologous expression in yeast.

A meta-analysis of transcriptomic profiles reveals molecular pathways response to cadmium stress of Gramineae.

As a non-essential heavy metal, cadmium (Cd) is toxic to plants. In the last 15 years, over 70 transcriptome studies have been published to decipher the molecular response mechanism against Cd stress in different plants. To extract generalization results from transcriptomic data across different plants and obtain some hub genes that respond to Cd stress, we carried out a meta-analysis of 32 published datasets.

New Insights into the Structure-Function Relationship of the Endosomal-Type Na, K/H Antiporter NHX6 from Mulberry ().

The endosomal-type Na, K/H antiporters (NHXs) play important roles in K, vesicle pH homeostasis, and protein trafficking in plant. However, the structure governing ion transport mechanism and the key residues related to the structure-function of the endosomal-type NHXs remain unclear. Here, the structure-function relationship of the only endosomal-type NHX from mulberry, MnNHX6, was investigated by homology modeling, mutagenesis, and localization analyses in yeast.

Ectopic Expression of Mulberry G-Proteins Alters Drought and Salt Stress Tolerance in Tobacco.

Heterotrimeric guanine-nucleotide-binding proteins (G-proteins) play key roles in responses to various abiotic stress responses and tolerance in plants. However, the detailed mechanisms behind these roles remain unclear. Mulberry ( L.

Genome-Wide Identification and Characterization of Four Gene Families Putatively Involved in Cadmium Uptake, Translocation and Sequestration in Mulberry.

The zinc-regulated transporters, iron-regulated transporter-like proteins (ZIPs), the natural resistance and macrophage proteins (NRAMP), the heavy metal ATPases (HMAs) and the metal tolerance or transporter proteins (MTPs) families are involved in cadmium (Cd) uptake, translocation and sequestration in plants. Mulberry ( L.), one of the most ecologically and economically important (as a food plant for silkworm production) genera of perennial trees, exhibits excellent potential for remediating Cd-contaminated soils.

Plant G-protein β subunits positively regulate drought tolerance by elevating detoxification of ROS.

Heterotrimeric guanine-nucleotide-binding proteins (G-proteins) consist of α, β and γ subunits and play important roles in response and tolerance to abiotic stresses in plants, but the function of the heterotrimeric G-protein β subunit in response to drought remains unclear. In the present study, the AGB1 mutants (agb1-2-1 and agb1-3-2) were more sensitive to drought than the wild-type. The overexpression of mulberry (Morus alba L.

Molecular characterization and expression analysis of the mulberry Na(+)/H(+) exchanger gene family.

Na(+)/H(+) exchangers (NHXs) have important roles in cellular pH, and Na(+) and K(+) homeostasis in plants. Mulberry is not only an important traditional economic woody plant known for its leaves, which are the exclusive food source of the silkworm Bombyx mori, but it can also adapt to many different adverse conditions, including saline environments. However, little is known about the NHXs in this important perennial tree.

Mulberry Transcription Factor MnDREB4A Confers Tolerance to Multiple Abiotic Stresses in Transgenic Tobacco.

The dehydration responsive element binding (DREB) transcription factors have been reported to be involved in stress responses. Most studies have focused on DREB genes in subgroups A-1 and A-2 in herbaceous plants, but there have been few reports on the functions of DREBs from the A-3-A-6 subgroups and in woody plants. Moreover, mulberry trees are ecologically and economically important perennial woody plants, but there has been little research on its stress physiology, biochemistry and molecular biology.
