Plant synthetic biology-based strategies for biofortification: (A) Overview of the vitamin B1 de novo biosynthesis pathway in plants. (B) The strategy of overexpression of endogenous biosynthetic genes. (C) The strategy of introduction of heterologous biosynthetic pathways. (D) The strategy of expression of nutrient-specific transporters. (E) The “suicide” catalytic mechanism of THI1 in higher plants and other eukaryotes, in which its cysteine residue is irreversibly consumed, resulting in enzyme inactivation after a single turnover. (F) The strategy of optimization of transcriptional regulation via transcription factor or promoter engineering. (G) The strategy of protein (directed) evolution.

Cover of the June 2025 issue (Volume 67, Issue 6) of the Journal of Integrative Plant Biology. The cover features a bright orange citrus fruit, cut in half transversely to reveal stylized representations of meiosis in each segment. White citrus flowers surround the fruit, and strands of DNA with notations indicating deletions run between the two halves. Cover designed by Yan-Jie Fan, Wen-Wu Guo and Xiao-Meng Wu.

Diagram of the plant shoot-root system, illustrating findings of a recent study, that fungi use Nudix effectors to disrupt plant phosphate sensing by breaking down inositol pyrophosphate signals, worsening disease (the exact mechanism remains unclear). The diagram also poses the question, "Do these effectors affect shoot-root communication and plant nutrition-immunity crosstalk?"

Pollen hydration, germination, and tube growth are vital processes that involve complex signaling pathways. Here, Kim et al report that OsPRK1/2/3-mediated #ROS signaling is required for #pollen tube #germination in #rice

The rice pollen-specific receptor-like kinases OsPRK1, OsPRK2, and OsPRK3 play a crucial role in reactive oxygen species (ROS)-mediated pollen hydration and germination. This diagram illustrates how triple mutants display male sterility due to decreased ROS levels and impaired pollen hydration, and their germination phenotype can be partially restored by exogenous application of H2O2.

Diagram of a cell cross-section focused on component interactions between the cytoplasm, nucleus, and amyloplast. Annotations indicate that overexpression of IbNAC22 improves starch and amylose contents, IbNAC22 directly activates the expression of IbGBSSI, a key gene for amylose biosynthesis but suppresses the expression of IbSBEI, a key gene for amylopectin biosynthesis. IbNAC22 directly interacts with IbNF-YA10, while overexpression of IbNF-YA10 significantly improves starch and amylose contents.
