Abstract:
... Background: Tethered cut-to-length and cable yarding systems with tethered falling equipment are increasingly used to harvest trees from slopes exceeding 30–60% more safely and at reduced financial cost than less mechanized harvest systems. Existing studies of harvest equipment typically isolate one or two pieces of equipment in a harvest system and often occur on sites with slopes below 50% and t ...

Abstract:
... Fog harvesting has been reckoned to be one of the most facile and economical approaches to alleviating the ever-increasing global water scarcity. Janus membranes, especially metallic ones, outperform other fog collectors in terms of fog harvesting efficiencies, and they are the selection for sustainable water production as passive devices. However, there is a lack of metallic Janus membranes with ...

Abstract:
... Invasive alien species (IAS) are both present and progressively invading environments worldwide causing an array of negative ecological, social, and economic impacts. Control through consumption, or the harvesting of invasives specifically for eating, appears to be a viable option in managing a number of problem species. However, while a handful of control through consumption initiatives have prov ...

Abstract:
... Development of water-stable metal–organic frameworks (MOFs) for promising visible-light-driven photocatalytic water splitting is highly desirable but still challenging. Here we report a novel p-type nickel-based MOF single crystal (Ni-TBAPy-SC) and its exfoliated nanobelts (Ni-TBAPy-NB) that can bear a wide range of pH environment in aqueous solution. Both experimental and theoretical results indi ...

Abstract:
... In land plants, both efficient light capture and photoprotective dissipation of chlorophyll excited states in excess require proper assembly of Photosystem II supercomplexes PSII-LHCs. These include a dimeric core moiety and a peripheral antenna system made of trimeric LHCII proteins connected to the core through monomeric LHC subunits. Regulation of light harvesting involves re-organization of th ...

Abstract:
... The Lycophyte Selaginella martensii efficiently acclimates to diverse light environments, from deep shade to full sunlight. The plant does not modulate the abundance of the Light Harvesting Complex II, mostly found as a free trimer, and does not alter the maximum capacity of thermal dissipation (NPQ). Nevertheless, the photoprotection is expected to be modulatable upon long‐term light acclimation ...

Abstract:
... ‘Huabai 1’ is a new albino tea germplasm, with high amino acids in its albinism period, however, the albino mechanism remains unknown. To understand the albinism mechanism of ‘Huabai 1’, molecular-level studies were carried out to reveal the functions of CsLHCII and CsSGR in albinism. In this study, transmission electron microscopy (TEM) observations revealed that albino leaves of ‘Huabai 1’ are m ...

Abstract:
... Confusion around the terms “legumes” and “pulses” has been a long-standing problem among consumers, health professionals, and researchers in the United States. The Food and Agricultural Organization defines pulses as legumes that are harvested solely as dry grain and include beans, peas, chickpeas, and lentils. For the first time ever, the 2020–2025 Dietary Guidelines for Americans recognized and ...

Abstract:
... There is a growing need of sustainable solutions for balancing agricultural production with the reduction of its environmental impacts. The rapid increase in sugarcane cultivation and the progressive conversion of pre-harvest burning (BH) to green harvest (GH) have brought into debate the contribution of agricultural sector to the greenhouse gas (GHG) mitigation. This study focused on the estimate ...
... The RIQ gene can optimize the structure of light-harvesting complex II by regulating the degree of granum stacking, and ultimately participates in plant light stress responses. The GmRIQ2 gene contributes to plant photoprotection and may be involved in negative regulation of yield. To understand the regulatory mechanisms of GmRIQ2 expression, we isolated the GmRIQ2 promoter (PGmRIQ2) from the KenF ...

Abstract:
... In plant chloroplasts, photosystem II (PSII) complexes, together with light‐harvesting complex II (LHCII), form various PSII‐LHCII supercomplexes (SCs). This process likely involves immunophilins, but the underlying regulatory mechanisms are unclear. Here, by comparing Arabidopsis thaliana mutants lacking the chloroplast lumen‐localized immunophilin CYCLOPHILIN28 (CYP28) to wild‐type and transgeni ...

Abstract:
... Arthrospira platensis is a kind of filament cyanobacteria, which is mainly helical with a few linear. The shape of the filaments, such as the length and the pitch, may change with the changes in the environment. Natural Arthrospira platensis FACHB793 is linear, although it has become helical due to a mutation introduced in the process of cultivation. To study the molecular mechanism responsible fo ...
