Molecular identification and expression patterns of sweet cherry HIPPs and functional analysis of PavHIPP16 in cold stress.

The HIPP proteins are involved in low-temperature stress, the growth of sweet cherry, and may be potential targets for genetic improvement. PavHIPP16 improved cold resistance in Arabidopsis. In response to abiotic stressors, the heavy metal-associated isoprenylated plant protein (HIPP) proteins play a crucial regulatory role.

Overexpression of PavHIPP16 from Prunus avium enhances cold stress tolerance in transgenic tobacco.

Background: The heavy metal-associated isoprenylated plant protein (HIPP) is an important regulatory element in response to abiotic stresses, especially playing a key role in low-temperature response.

Results: This study investigated the potential function of PavHIPP16 up-regulated in sweet cherry under cold stress by heterologous overexpression in tobacco. The results showed that the overexpression (OE) lines' growth state was better than wild type (WT), and the germination rate, root length, and fresh weight of OE lines were significantly higher than those of WT.

Chinese cherry CpMYB44-CpSPDS2 module regulates spermidine content and florescence in tobacco.

The flower bud differentiation plays a crucial role in cherry yield and quality. In a preliminary study, we revealed the promotion of spermidine (Spd) in bud differentiation and quality. However, the molecular mechanism underlying Spd regulating cherry bud differentiation remains unclear.

Molecular characterization and evolutionary relationships of DOFs in four cherry species and functional analysis in sweet cherry.

The DOF (DNA binding with one finger) has multiple functions in plants. However, it has received little attention in the research field of cherries. In this study, the evolutionary relationship and molecular characterization of DOF in four cherry species were analyzed, revealing its expression pattern in sweet cherry.

Genome-wide analysis of C2H2 zinc finger family and their response to abiotic stresses in apple.

C2H2-type zinc finger proteins are one of the most widely studied families in plants and play important roles in abiotic stress responses. In the present study, the physicochemical properties, chromosomal locations, evolutionary relationships, and gene structures of 54 C2H2 zinc finger protein (ZFP) family members were analyzed in apple. The MdC2H2-ZFP genes were phylogenetically clustered into seven subfamilies distributed in different densities on 16 chromosomes.

Functional analysis of sweet cherry PavbHLH106 in the regulation of cold stress.

Sweet cherry PavbHLH106 was up-regulated under cold induction and overexpressed to enhance the cold resistance in tobacco by mediating the scavenging of ROS through increasing of antioxidant enzyme activity. Sweet cherry (Prunus avium L.) is an economically important fruit.
