Abstract:
... In most terrestrial arthropods, cuticular hydrocarbons (CHCs) function to assist in desiccation tolerance and chemical communications. However, few studies have clarified whether CHC profiles change among developmental stages or among different morphs in non‐social insects. In the present study, we evaluated how CHC profiles change in accordance with polyphenism in the host‐alternating aphid Proci ...

Abstract:
... There is a gap in the conceptual framework linking genes to phenotypes (G2P) for non-model organisms, as most non-model organisms do not yet have genomic resources readily available. To address this, researchers often perform literature reviews to understand G2P linkages by curating a list of likely gene candidates, hinging upon other studies already conducted in closely related systems. Sifting t ...

Abstract:
... Wood density is one of the main functional traits affecting demographic rates of tropical trees. However, little is known about how this translates into abundance of trees in local assemblages. I hypothesized that: (1) higher wood density would generally result in better adaptation to prevailing environmental conditions in seasonally dry semideciduous forests, which would translate into numerical ...

Abstract:
... Drought limits the pear yield and quality. The birch-leaf pear (Pyrus betulifolia Bunge) is one of the most frequently used pear rootstocks. Identifying genes involved in drought resistance of P. betulifolia would suggest candidate genes for molecular breeding. We used single-molecule long-read sequencing technology to investigate the transcriptome of birch-leaf pear under drought stress. As a res ...

Abstract:
... Drought is the leading environmental threat affecting crop productivity, and plants have evolved a series of mechanisms to adapt to drought stress. The FT-interacting proteins (FTIPs) and phosphatidylethanolamine-binding proteins (PEBPs) play key roles in developmental processes, whereas their roles in the regulation of stress response are still largely unknown. Here, we report that OsFTIP1 negati ...

However, it is currently unknown if and how Si affects different wheat landraces, especially with respect to their innate Si accumulation properties. In this study, significant and consistent differences in Si accumulation between landraces were identifi ...

Abstract:
... Droughts in humid regions may have more severe consequences owing to a lack of drought-resistant measures and awareness. The Yunnan Province, in the humid southwestern part of China, experienced an extreme drought from 2009 to 2010. However, few studies have systematically explored agricultural droughts in this region. Based on revised global multi-source microwave-based SM products, the European ...

Abstract:
... Cryopreservation is a key method of preservation of biological material for both medical treatments and conservation of endangered species. In order to avoid cellular damage, cryopreservation relies on the addition of a suitable cryoprotective agent (CPA). However, the toxicity of CPAs is a serious concern and often requires rapid removal on thawing which is time consuming and expensive.The princi ...

Despite that CRKs control important aspects of plant development, only few proteins have functionally been characterized. In this work, we analyzed the function of CRK33 by characterizing two insertional lines. The stomatal density and stomat ...
