PbBPC4 involved in a xylem-deficient dwarf phenotype in pear by directly regulating the expression of PbXND1 J. Plant Physiol. (IF 4.3) Pub Date : 2023-11-13 Di Wang, Bingqing Qie, Azheng Wang, Minmin Wang, Pingyuan Dai, Lijuan Xiao, Rui Zhai, Chengquan Yang, Zhigang Wang, Lingfei Xu
Dwarfing is an important agronomic trait in fruit breeding. At present, dwarf cultivars or dwarfing rootstocks are used for high-density planting. Although some dwarf rootstocks have been used in the cultivation of pear (Pyrus bretschneideri Rehd), the breeding of dwarf pear rootstocks or cultivars is still sorely lacking. A previous study reported that PbXND1 results in a xylem-dwarf phenotype in

Functions of sucrose and trehalose 6-phosphate in controlling plant development J. Plant Physiol. (IF 4.3) Pub Date : 2023-11-17 Moritz Göbel, Franziska Fichtner
Plants exhibit enormous plasticity in regulating their architecture to be able to adapt to a constantly changing environment and carry out vital functions such as photosynthesis, anchoring, and nutrient uptake. Phytohormones play a role in regulating these responses, but sugar signalling mechanisms are also crucial. Sucrose is not only an important source of carbon and energy fuelling plant growth

Pour some sugar on me: The diverse functions of phenylpropanoid glycosylation J. Plant Physiol. (IF 4.3) Pub Date : 2023-11-11 Arthur de Barros Rates, Igor Cesarino
The phenylpropanoid metabolism is the source of a vast array of specialized metabolites that play diverse functions in plant growth and development and contribute to all aspects of plant interactions with their surrounding environment. These compounds protect plants from damaging ultraviolet radiation and reactive oxygen species, provide mechanical support for the plants to stand upright, and mediate

The seven rice vacuolar sorting receptors localize to prevacuolar compartments J. Plant Physiol. (IF 4.3) Pub Date : 2023-11-10 Lei Yang, Liwen Jiang
Vacuolar sorting is critically important in plants as it regulates the mobilization of proteins and plays a major role in important agricultural traits like yield and seed protein content. Vacuolar sorting receptors (VSRs) are integral membrane proteins that mediate protein trafficking from the Golgi apparatus to the vacuole via the intermediate membrane-bound prevacuolar compartment (PVC)/multivesicular

Preparation of leaf protoplasts from Populus (Populus × xiaohei T. S. Hwang et Liang) and establishment of transient expression system J. Plant Physiol. (IF 4.3) Pub Date : 2023-11-03 Chengjun Yang, Ruiqiang Yu, Jinbo Li, Kai Wang, Guanjun Liu
Poplar, as a typical woody plant, is an ideal raw material for the production of lignocellulose biofuel. However, the longer life cycle is not conducive to the rapid identification of poplar genes. At present, protoplasts have been used for gene function identification and high-throughput analysis in many model plants. In this paper, a simplified and efficient protoplast isolation and transient expression
