Seed priming with ascorbic acid and spermidine regulated auxin biosynthesis to promote root growth of rice under drought stress.
Front Plant Sci
December 2024
National Key Laboratory of Crop Genetic Improvement, College of Plant Science and Technology, Huazhong Agricultural University, Wuhan, China.
Introduction: Drought stress severely hampers seedling growth and root architecture, resulting in yield penalties. Seed priming is a promising approach to tolerate drought stress for stand establishment and root development.
Methods: Here, various seed priming treatments, .
OsPAD1, encoding a non-specific lipid transfer protein, is required for rice pollen aperture formation.

Article Synopsis
- - Plant lipid transfer proteins (LTPs) are crucial for moving lipids between membranes, impacting pollen wall development, including the pollen aperture structure.
- - The study focuses on a rice mutant called pollen aperture defect 1 (Ospad1), which shows male sterility due to abnormal pollen grain development linked to a non-specific LTP that fails to properly bind lipids.
- - Researchers found that OsPAD1 interacts with a gene involved in pollen development, providing new insights into how LTPs function in forming pollen apertures, which could have broader implications for other cereal crops.
RNA modifications in plant adaptation to abiotic stresses.

Epitranscriptomic chemical modifications of RNAs have emerged as potent regulatory mechanisms in the plant stress adaptation process. Currently, over 170 distinct chemical modifications have been identified in mRNAs, tRNAs, rRNAs, microRNAs (miRNAs), and long-noncoding RNAs (lncRNAs). The genetic and molecular studies have identified the genes responsible for adding and removing chemical modifications on RNA molecules, known as "writers" and "erasers," respectively.

Red yeast rice, traditionally used in Asian cuisine and increasingly marketed as a dietary supplement for cholesterol management, has recently been linked to kidney dysfunction in Japan. In late 2023 to early 2024, multiple cases involving specific Beni-koji (red yeast rice) tablets from three different Beni-koji preparations, prompted a safety reevaluation. Although citrinin, a known nephrotoxin of red yeast rice, was not produced by the implicated strains, new safety concerns emerged.

Conventional approaches like Agrobacterium-mediated transformation, viral transduction, biolistic particle bombardment, and polyethylene glycol (PEG)-facilitated delivery methods have been optimized for transporting specific genes to various plant cells. These conventional approaches in genetically modified crops are dependent on several factors like plant types, cell types, and genotype requirements, as well as numerous disadvantages such as time-consuming, untargeted distribution of genes, and high cost of cultivation. Therefore, it is suggested to develop novel techniques for the transportation of genes in crop plants using tailored nanoparticles (NPs) of manipulative and controlled high-performance features synthesized using green and chemical routes.
