Summary: Theanine, a non-proteinogenic amino acid abundant in tea plants, gives tea infusion its unique taste and anti-stress effects. The content of theanine in tea is closely correlated with its quality. However, the regulation of theanine decrease in late spring is still unknown. Through genetic screening, a yeast mutant, gdh2, was found to be hypersensitive to theanine and accumulated more of it, indicating a potential role of CsGDH2.1 in theanine accumulation in tea plants. CsGDH2.1 was found to be expressed in the mitochondria and highly expressed in young tissues of tea plants. CsGDH2.1 was also observed to regulate theanine accumulation in new shoots in late spring through glutamate catabolism.

Summary: The research investigated the uptake, accumulation, and translocation of perchlorate in a tea plant-hydroponic solution system, revealing that the concentration of perchlorate in tea tissues increased with exposure level and time. Results showed that after being transplanted to a perchlorate-free solution, mature leaves had significantly reduced perchlorate levels, while new shoots and solutions had increased levels. The study also found that the major reservoir of perchlorate in roots and leaves were the cell-soluble fractions, explaining the translocation within the tea plant-hydroponic solution system.

Summary: Salt stress has distinct effects on the root xylem development of Arabidopsis seedlings, leading to the formation of protoxylem gaps. The extent of protoxylem gaps positively correlates with salt tolerance. Reduced gibberellin signaling and the involvement of various genes are required for the formation of protoxylem gaps. These findings provide important insights into the acclimation of plants to high salt conditions.

Summary: The appropriate acidic environment promotes the differentiation of adventitious roots in tea plants. In this study, it was found that pH 4.5 was the most suitable condition for the differentiation of adventitious roots. Several genes related to adventitious root differentiation showed differential expression at pH 4.5 compared to pH 7.0, and the expression levels of these genes were regulated by auxin and brassinosteroid. Additionally, auxin and brassinolide were found to affect the differentiation of adventitious roots.

Summary: The study reveals that NAA can promote the formation of AR in tea cuttings and has a synergistic effect with endogenous hormones. The level of the most important endogenous AR inductor, IAA, is reduced in response to NAA treatment. Comparative transcriptome analysis identifies DEGs potentially involved in NAA-mediated AR formation in tea stem cuttings. Weighted gene co-expression network analysis identifies several hub genes that may play important roles in AR formation in tea cuttings.

Summary: This study investigated the root foraging strategies of tea plants under soil potassium heterogeneity. It found that the low-K tolerant genotype 1511 showed better acclimation to K heterogeneity than the low-K intolerant genotype 1601. The adaptation of 1511 was attributed to a smart root foraging strategy, including the development of more roots (especially fine roots) in the K-enriched side, secretion of more organic acids in the low-K side to activate soil K, and cellulose decomposition promoting root proliferation. This research provides practical insights into the adaptation strategies of clonal woody plants to soil nutrient availability.

Summary: This study characterized the open chromatin regions (OCRs) in rice pistils and anthers using transposase-accessible chromatin sequencing. The results showed that there were more OCRs in pistils than in anthers, and these OCRs were enriched in gene transcription start sites and tightly associated with gene expression. Transcription factor binding motifs were also found to be enriched at these OCRs, validating their role in gene regulation. Additionally, the study found that the open chromatin of pistils and anthers responded differently to low temperature.

Summary: This study investigated the effect of moderate soil drying on maize production and water use efficiency. The results showed that compared to well-watered conditions, moderate soil drying increased kernel yield, reduced irrigation water consumption, and improved irrigation water use efficiency. Additionally, moderate soil drying enhanced physiological performances, such as the activity of superoxide dismutase and photosynthetic rate, and increased the contents of hormones related to kernel development. These findings suggest that moderate soil drying can achieve the dual goal of increasing food production and saving water in maize cultivation.

Summary: Salt stress is a major constraint to plant growth and production. Abscisic acid (ABA) has been shown to play a crucial role in plants under salt stress, and trehalose (Tre) has emerged as an effective osmolyte for inducing salt tolerance. However, the mechanism of interaction between ABA and Tre in rice seedlings under salt stress remains unclear. This study found that exogenous Tre significantly improved salt tolerance in rice seedlings by enhancing the activity of antioxidant enzymes. The expression of the OsNCED3 gene was induced by salt stress. Overexpression of OsNCED3 enhanced salt tolerance, while knockout of OsNCED3 reduced salt tolerance in rice seedlings. Metabolite analysis showed that Tre content was increased in OsNCED3-overexpressing seedlings and decreased in nced3 mutants. The application of both ABA and Tre improved salt tolerance in nced3 mutants compared to wild-type seedlings. The OsTPP3 gene was found to be induced by both ABA and salt treatments. Overexpression of OsTPP3 enhanced salt tolerance, while knockout of OsTPP3 reduced salt tolerance in rice seedlings. Additionally, Tre content was higher in OsTPP3-overexpressing seedlings and lower in tpp3 mutant seedlings compared to wild-type plants. Exogenous Tre application also enhanced salt tolerance in tpp3 mutant plants. Overall, these results demonstrate that salt-induced ABA activates the expression of OsTPP3, leading to an increase in Tre content and improvement in salt tolerance in rice seedlings.
