Root-knot nematodes (RKNs) of the genus Meloidogyne pose the most significant threats to global food security due to their destructive nature as plant-parasitic nematodes. Although significant attention has been devoted to investigating the gene transcription profiling of RKNs, our understanding of the translational landscape of RKNs remains limited. In this study, we elucidated the translational landscape of Meloidogyne incognita through the integration of translatome, transcriptome and quantitative proteome analyses.

Carbon catabolite repression (CCR) and de-repression (CCDR) are critical for fungal development and pathogenicity, yet the underlying regulatory mechanisms remain poorly understood in pathogenic fungi. Here, we identify a serine/threonine protein phosphatase catalytic subunit, Pp4c, as essential for growth, conidiation, virulence, and the utilization of carbohydrates and lipids in Magnaporthe oryzae. We demonstrate that the protein phosphatase 4 complex (Pp4c and Smek1 subunits), the AMP-activated protein kinase (AMPK) Snf1, and the transcriptional regulators CreA (repressor) and Crf1 (activator) collaboratively regulate the utilization of non-preferred carbon sources.

The gradual increase in the consumption of mineral nitrogen is leading to heightened levels of harmful air pollutants, particularly NO emissions from the agriculture sector. A potential solution to address the issues arising from the excessive use of urea in wheat is the substitution of conventional urea with nano urea. This study aimed to quantify the effects of nano urea, both independently and in conjunction with prilled urea, under various agroclimatic and sowing conditions in India.

Informing and engaging all actors in the land sector, including land-owners and managers, researchers, policy-makers and citizens, on the most effective sustainable land-based solutions and behavioural changes is a key strategy for achieving climate change adaptation and mitigation targets at the global as well as at EU and local level. One requisite to support actors in the land sector is to provide them publicly available, reliable and ready-to-use information related to the implementation of Land-based Adaptation and Mitigation Solutions (LAMS). Here we introduce a LAMS catalogue, a collection of meaningful quantitative and qualitative information on 60 solutions characterised according to a set of specifications (e.

The environmental impact of insecticides used as ectoparasitic treatments for companion animals is not well understood, since they are not subject to detailed environmental risk assessment. Many of these treatments include active ingredients such as fipronil and imidacloprid that are banned from agricultural use in the EU. These treatments are applied topically and can remain on the animal's fur for an extended period of time.

Compared to outdoor mango cultivation in the tropics, greenhouse cultivation in temperate regions is less reported due to its short history and small scale. Here, we evaluated for the first time the taste-focused quality of greenhouse-grown mangoes (Irwin) by GC-MS metabolic profiling and sensory evaluation for over three years (2021-2023). The relative standard deviation in sensory evaluation scores was approximately 15 % each year.

The ecology of watersheds plays an important role in regulating regional climate and human activities. The sediment-soil system in the middle and lower reaches of the Yellow River Basin (Henan section) was explored. The spatial distribution characteristics of heavy metals (HMs) showed that tributaries, which are affected by anthropogenic activities, contain higher concentrations of HMs than the main channel.

Can spatial self-organization inhibit evolutionary adaptation?

The Swiss Institute for Dryland Environmental and Energy Research, BIDR, Ben-Gurion University of the Negev, Midreshet Ben-Gurion 8499000, Israel.

Plants often respond to drier climates by slow evolutionary adaptations from fast-growing to stress-tolerant species. These evolutionary adaptations increase the plants' resilience to droughts but involve productivity losses that bear on agriculture and food security. Plants also respond by spatial self-organization, through fast vegetation patterning involving differential plant mortality and increased water availability to the surviving plants.

Vascular calcification(VC) significantly increases the risk of cardiovascular events, leading to thickening of the myocardium and arteries, coronary heart disease, heart failure, and potentially triggering myocardial infarction and sudden cardiac death. Although VC is a reversible process, there are currently no methods or medications in clinical practice that can completely reverse or cure it. The current treatment strategies primarily focus on slowing the progression of VC and exploring new diagnostic and therapeutic approaches, making the identification of early diagnostic markers for VC particularly important.

Metamorphic proteins switch reversibly between distinctly different folds often with different functions under physiological conditions. Here, the kinetics and thermodynamics of the fold-switching at different temperatures in a metamorphic protein, KaiB, involved in cyanobacterial circadian clock, reveal that enthalpy-driven the fold-switching to form fold-switched KaiB (fsKaiB) and the fsKaiB and ground-state KaiB (gsKaiB) are more dominantly at lower and higher temperatures, respectively. Thermodynamic analysis indicates that conformational and solvent entropy have opposing effects on KaiB's fold-switching.

Microbubble-assisted starch modification (MASM) using different gases (N, CO and air) was employed to assess the effects of hydrodynamic cavitation (HC) on various botanical starches, including potato, wheat, corn and rice. SEM showed that N- and CO- microbubbles created more pronounced holes and cracks on the starch surfaces than air-microbubbles. The hydrodynamic cavitation-assisted microbubble (HCAM) treatment significantly reduced the amorphous and crystalline structures in potato and wheat starches, with less impact observed in corn and rice.
