Reducing nitrogen (N) application is crucial in addressing the low N utilization efficiency (NUE) and the risks of environmental pollution in wheat production. Improving low N (LN) tolerance in wheat can help balance the conflict between wheat growth and reduced N fertilization. Hydroponic experiments were conducted using Yangmai158 (LN-tolerant) and Zaoyangmai (LN-sensitive) cultivars to study whether LN priming (LNP) in the 3-leaf stage can improve the photosynthetic capacity of wheat seedlings under N-deficit stress at the 5-leaf stage.

Article Synopsis
  • - Psoriasis is a chronic skin condition linked to immune system dysfunction and oxidative stress, with the neonatal Fc receptor (FcRn) playing a potential role in its severity according to clinical analyses.
  • - In a mouse model of psoriasis, researchers found lower levels of FcRn in affected skin, and the ferroptosis pathway was activated, suggesting that FcRn may influence this process through the STAT3/SLC7A11 signaling pathway.
  • - Experiments indicated that depleting FcRn increased psoriatic lesions and ferroptosis, while inhibiting this process or activating FcRn improved symptoms, pointing to possible new treatments for psoriasis.

The genetic diversity in tetraploid wheat provides a genetic pool for improving wheat productivity and environmental resilience. The tetraploid wheat had strong N uptake, translocation, and assimilation capacity under N deficit stress, thus alleviating growth inhibition and plant N loss to maintain healthy development and adapt to environments with low N inputs. Tetraploid wheat with a rich genetic variability provides an indispensable genetic pool for improving wheat yield.

Although tetraploid wheat has rich genetic variability for cultivar improvement, its physiological mechanisms associated with photosynthetic productivity and resilience under nitrogen (N) deficit stress have not been investigated. In this study, we selected emmer wheat (Kronos, tetraploid), Yangmai 25 (YM25, hexaploid), and Chinese Spring (CS, hexaploid) as materials and investigated the differences in net photosynthetic rate (Pn), carboxylation capacity, electron transfer capacity, photosynthetic product output, and photosynthetic N allocation under normal N (CK) and low N (LN) through hydroponic experiments. Tetraploid emmer wheat (Kronos) had a stronger photosynthetic capacity than hexaploid wheat (YM25, CS) under low N stress, which mainly associated with the higher degree of PSII opening, electron transfer rate, Rubisco content and activity, ATP/ADP ratio, Rubisco activase (Rca) activity and Rubisco activation state, and more leaves N allocation to the photosynthetic apparatus, especially the proportion of N allocation to carboxylation under low N stress.

The use of slow-release fertilizers and seed-fertilizers cause localized high-ammonium (NH ) environments in agricultural fields, adversely affecting wheat growth and development and delaying its yield. Thus, it is important to investigate the physiological responses of wheat and its tolerance to NH stress to improve the adaptation of wheat to high NH environments. In this study, the physiological mechanisms of ammonium tolerance in wheat () were investigated in depth by comparative analysis of two cultivars: NH -tolerant Xumai25 and NH -sensitive Yangmai20.

Efficacy of clinical chemotherapeutic agents depends not only on direct cytostatic and cytotoxic effects but also involves in eliciting (re)activation of tumour immune effects. One way to provoke long-lasting antitumour immunity is coined as immunogenic cell death (ICD), exploiting the host immune system against tumour cells as a "second hit". Although metal-based antitumour complexes hold promise as potential chemotherapeutic agents, ruthenium (Ru)-based ICD inducers remain sparse.

The endogenous stimulating molecule melatonin (N-acetyl-5-methoxytryptamine, MT) has an important function in mitigating the impact of multiple abiotic stressors. However, the ameliorating effect of MT on chromium (Cr) stress and its mechanisms remains unclear. Therefore, the present study aimed to clarify the mitigating effect of exogenous MT (0 μM and 100 μM) on wheat seedlings under Cr (0 μM and 50 μM) stress stemming from the growth and physiological characteristics, phytochelatin (PC) biosynthesis, Cr subcellular distribution, and antioxidant system of the plants in these treatments.

Shoot branching is inhibited by a low red/far-red ratio (R/FR). Prior studies have shown that the R/FR suppressed branching by promotes bud abscisic acid (ABA) accumulation directly. Given that wheat tiller buds are wrapped in leaf sheaths and may not respond rapidly to a R/FR, systemic cytokinin (CTK) may be more critical.
