Improving poplar productivity across a wide spectrum of nitrogen conditions is a primary objective in poplar breeding. In this research, we engineered transgenic poplars to overexpress the () gene. The results showed that these transgenic plantlets significantly outperformed the wild-type control in terms of growth under both nitrogen-poor and nitrogen-rich conditions, exhibiting increased biomass, height, and root development.

Leaf nitrogen allocation plays a crucial role in determining both photosynthetic function and structural development of plants. However, the effects of drought, salt stress, and their combination on leaf nitrogen allocation, and how these affect mesophyll conductance ( ) and photosynthesis, remain poorly understood. In this study, we first investigated variations in photosynthetic characteristics and leaf nitrogen allocation, and analyzed the relationship between and leaf nitrogen allocation ratios in under drought, salt and combined drought-salt stress.

Background: The recurrence patterns of different types of pathologic regression of the primary tumor and lymph nodes in patients with esophageal squamous cell carcinoma (ESCC) after neoadjuvant chemoradiotherapy (NCRT) are little known, especially in ypT0N+ patients.

Methods: We included 582 patients with ESCC who had esophagectomy after NCRT or neoadjuvant radiotherapy (NRT) from 3 institutions. The patients were divided into 4 groups: ypT0N0, ypT0N+, ypT+N0, and ypT+N+ according to the type of pathological regression of the primary tumor and lymph nodes.

Background: Non-structural carbohydrates (NSCs) are key substances for metabolic processes in plants, providing energy for growth, development, and responses to environmental stress. Pruning mother bamboo in a clump can significantly affect the NSCs allocation of new shoots, thereby affecting their growth. Moso bamboo (Phyllostachys edulis) is an important economic bamboo species with a highest planting area in China.

Leaf nitrogen content (LNC) is a crucial indicator for assessing the nitrogen status of forest trees. The LNC retrieval can be achieved with the inversion of the PROSPECT-PRO model. However, the LNC retrieval from the commonly used leaf bidirectional reflectance factor (BRF) spectra remains challenging arising from the confounding effects of mesophyll structure, specular reflection, and other chemicals such as water.

Cadmium (Cd) is a toxic heavy metal that poses a serious threat to crop safety and human health. Aspartate aminotransferase (AspAT) is a prime enzyme engaged in amino acid metabolism, contributing essential metabolic substances for plant growth and acclimatization to various stresses. In this study, we identified a novel AspAT9 gene with high responsiveness to Cd stress from poplar 'Nanlin895' and subsequently transformed it into Arabidopsis.

Browning presents a significant challenge in the culture of economically important woody plants, primarily due to high levels of lignification and the accumulation of secondary metabolites. This phenomenon hampers the development of efficient regeneration and genetic transformation systems across diverse species. This review examines the internal and external factors contributing to browning, including genetic attributes, tree genotypes, physiological state of explants, explant surface sterilization, medium composition, and overall culture conditions.

Article Synopsis
  • In plants, hetACCase is crucial for starting fatty acid synthesis by producing malonyl-CoA, with its activity tightly regulated depending on the plant's needs.
  • A coexpression analysis in Arabidopsis identified the gene REGULATOR OF FATTY ACID SYNTHESIS 1 (RFS1), which interacts with CARBOXYLTRANSFERASE INTERACTOR 1 (CTI1) and plays a role in regulating hetACCase.
  • Knockout experiments showed that loss of RFS genes increases hetACCase activity and fatty acid content in plants, suggesting a potential strategy for breeding plants with higher oil yields.

Flavonols are important secondary metabolites that enable plants to resist environmental stresses. Although MYB regulation of flavonol biosynthesis has been well studied, the long non-coding RNA (lncRNA)-MYB networks involved in regulating flavonol biosynthesis remain unknown. Ginkgo biloba is rich in flavonols, which are the most important medicinal components.

, usually referred to as a "living fossil," is widely planted in many countries because of its medicinal value and beautiful appearance. Owing to ginkgo's high resistance to drought stress, ginkgo seedlings can even survive withholding water for several days without exhibiting leaf wilting and desiccation. To assess the physiological and transcriptomic mechanisms involved in the drought stress and re-watering responses of , ginkgo seedlings were subjected to drought treatment for 15 d (D_15 d) and 22 d (D_22 d) until they had severely wilted, followed by re-watering for 3 d (D_Re3 d) to restore normal growth.

To develop an optimized controlled-release system based on temperature-sensitive poly(N-isopropylacrylamide) (PNIPAAm) nanofibers, we prepared three types of temperature-controlled preservative films. These films were composed of PNIPAAm, polyvinyl alcohol (PVA), polylactic acid (PLA), and lemon essential oil (LEO), and were fabricated using uniaxial, coaxial, and layered spinning techniques. The nanofiber films obtained by layered spinning exhibited a sandwich structure, demonstrating superior physical barrier properties, mechanical strength, and thermal resistance.

Old trees are remarkable for their ability to endure for centuries or even millennia, acting as recordkeepers of historical climate and custodians of genetic diversity. The secret to their longevity has long been a subject of fascination. Despite the challenges associated with studying old trees, such as massive size, slow growth rate, long lifespan and often remote habitat, accumulating studies have investigated the mechanisms underlying tree aging and longevity over the past decade.

Tertiary lymphoid structures (TLSs) were associated with survival in esophageal squamous cell carcinoma (ESCC) undergoing surgery alone (SA). However, their clinical relevance in neoadjuvant therapies remains less known.
