Article Synopsis
- * Researchers identified 20 phospholipase D (PLD) genes in the pear and classified them into five subfamilies, revealing their diverse evolutionary backgrounds.
- * The study found that the gene PbrPLD2 plays a crucial role in enhancing drought tolerance, making it a key target for improving resilience in pears and other fruit crops through breeding practices.
Drought poses significant challenges to agricultural production, ecological stability and global food security. While wild pear trees exhibit strong drought resistance, cultivated varieties show weaker drought tolerance. This study aims to elucidate the molecular mechanisms underlying pear trees' response to drought stress.

- Stone cells are special cells in pears that help make them crunchy and are important for their quality and value.
- Scientists studied a specific group of genes (PbPDCB) in pears that might affect how these stone cells develop and found 25 of them.
- By changing the expression of one of these genes, PbPDCB16, they noticed that more of a substance called callose and less lignin (which makes cells stronger) resulted, affecting how the cells communicate with each other.
Pear anthracnose caused by Colletotrichum fructicola is one of the main fungal diseases in all pear-producing areas. The degradation of ubiquitinated proteins by the 26S proteasome is a regulatory mechanism of eukaryotes. E3 ubiquitin ligase is substrate specific and is one of the most diversified and abundant enzymes in the regulation mechanism of plant ubiquitination.

- Glucose is important for fruit development and helps in making lignin, a substance that gives strength to plants, especially in pears, but its exact role isn't well understood.
- Researchers studied pear calli (plant tissue) treated with glucose and found that it increased lignin levels and changed many genes related to lignin production.
- A specific gene called PbPFP was identified as helping to boost lignin production when glucose is present, suggesting it plays a key role in how glucose affects lignin in pears.
Light environment is an indispensable factor that regulates multitudinous developmental processes during the whole life cycle of plants, including fruit development. Stone cells which negatively influence pear fruit quality because of their strongly lignified cell wall are also affected by light, however, how light qualities influence lignin biosynthesis in pear remains unclear. Here, the calli of European pear (Pyrus communis L.
