Genome-wide identification of the papaya-like cysteine protease family in poplar and determination of the functional role of PeRD19A in conferring salt tolerance.

Papain-like cysteine proteases (PLCPs) are a large class of proteolytic enzymes involved in plant growth and development as well as plant responses to biological and abiotic stresses. However, there is no detailed characterization of PLCPs genes in poplar. In this study, a genome-wide analysis of the poplar PtrPLCPs family revealed 47 PtrPLCPs, which were classified into nine subfamilies according to their phylogeny: RD21, CEP, XCP, XBCP3, SAG12, RD19 (5), ALP, CTB, and the lost THI subgroups.

Environmental risk assessment of the surface sediments based on trace elements analysis from the largest freshwater lake in the southern slope of the Himalaya, Nepal.

Freshwater ecosystems, including high-altitude lakes, can be affected by trace metal pollution derived from a mix of natural sources and anthropogenic activities. These pollutants often collect in surface sediments, with notable concentrations in the deeper areas of lakes. To evaluate the environmental risk associated with metal contaminated sediment in Rara Lake, southern Himalaya, surface sediment samples were systematically collected in November 2018, with a subsequent specific emphasis on determinations of trace element concentrations.

Genome-Wide Identification and Expression Profiles of Nuclear Factor Y A Transcription Factors in Blueberry Under Abiotic Stress.

Nuclear Factor Y A (NF-YA) transcription factors are widely involved in multiple plant biological processes, such as embryogenesis, abscisic acid signaling, and abiotic stress response. This study presents a comprehensive genome-wide identification and expression profiling of NF-YA transcription factors in blueberry (), an important economic crop with good adaptability, under abiotic stress conditions. Given the economic significance and health benefits of blueberries, understanding their responses to environmental stresses, such as salt, drought, and temperature extremes, is crucial.

Lucanus qizhihaoi, a new stag beetle from Wuyishan National Park of Fujian, China (Coleoptera: Lucanidae: Lucaninae).

A new stag beetle species is described from Wuyishan National Park of Fujian, China, Lucanus qizhihaoi Lin, Su, Xin & Song, new species, which represents the easternmost distribution record of the L. boileaui group, previously known only from southwestern China and northern Indochina Peninsula. Evidences are found on morphological characters, the mitochondrial marker COI and significant geographic isolation to clearly distinguished the new species from its closest relative, L.

Comparative analysis of chloroplast genomes and phylogenetic relationships in the endemic Chinese bamboo (Bambusoideae).

Introduction: Wen is a small yet taxonomically challenging genus within the Arundinarieae tribe. Recent molecular studies have suggested it may not be monophyletic. However, limited species sampling and insufficient molecular marker information have resulted in poorly resolved phylogenetic relationships within this genus.

Saline-alkali stress affects the accumulation of proanthocyanidins and sesquiterpenoids via the MYB5-ANR/TPS31 cascades in the rose petals.

Rose () petals are rich in diverse secondary metabolites, which have important physiological functions as well as great economic values. Currently, it remains unclear how saline and/or alkaline stress(es) influence the accumulation of secondary metabolites in rose. In this study, we analyzed the transcriptome and metabolite profiles of rose petals under aline-alkali stress and uncovered the induction mechanism underlying major metabolites.

Comparison of quality characteristics of reconstituted glutinous rice flour and sweet dumplings with various beans.

This study blended five types of beans-florid kidney bean, red adzuki bean, chickpea, black bean, and white kidney bean-with glutinous rice flour (GRF) to create a synergistic heat-moisture treatment (HMT). We investigated the effects of this combination on the digestibility of the glutinous rice mixture and the quality of sweet dumplings. The inclusion of beans, along with HMT, altered the granular morphology, adhesive qualities, thermal characteristics, crystallinity, and protein secondary structure of the blended powders compared to GRF.

Transcription Factor and Protein Regulatory Network of in Response to Pine Wilt Nematode Infection.

Pine wilt disease, caused by , is a highly destructive and contagious forest affliction. Often termed the "cancer" of pine trees, it severely impacts the growth of Masson pine (). Previous studies have demonstrated that ectopic expression of the gene from in notably enhances resistance to pine wilt nematode infection.

Impact of invasive alien plants on the resident floral diversity in Koshi Tappu Wildlife Reserve, Nepal.

Invasive alien plant species (IAPS) pose a serious threat to overall plant biodiversity across the globe. Nepal's national parks and protected areas are not devoid of the impact of IAPS. Unfortunately, there is a substantial gap in knowledge regarding the extent and impact of invasion in protected areas of Nepal.

Application of for the control of gray mold caused by in blueberry and mechanisms of action: inducing phenylpropanoid pathway metabolism.

Background: a blueberry gray mold, is one of the main diseases affecting postharvest storage, causing significant losses. Several studies have shown that can prevent the growth of plant pathogens by producing various antibacterial substances, and can induce plant resistance. However, research on the biological management of post-harvest gray mold in blueberries using remains unclear.

Phylogeography of the ambrosia beetle Euwallacea interjectus (Coleoptera: Curculionidae: Scolytinae): an emerging poplar pest and its Fusarium mutualists from poplar plantations in China.

Native to Asia, Euwallacea interjectus (Blandford) (Coleoptera: Curculionidae: Scolytinae) is a destructive and invasive pest of live trees, and now it has been found in the United States and Argentina. In recent years, this pest appeared in high densities in poplar monocultures from Eastern China (Jiangsu and Shanghai) and Argentina and caused significant poplar mortality. However, the origin of the pests related to tree damage and the Fusarium mutualists from some poplar zones in China remained unclear.

Understanding the impacts of street greening patterns and wind directions on the dispersion of fine particles.

Inappropriate planting patterns can increase pollutant concentrations and threaten human health. This study examined three greening patterns (trees, trees + hedges, and hedges) using the ENVI-met model to evaluate the different effects of various planting patterns on PM dispersion within an idealized 3D street canyon under three typical wind directions. Results showed that street greenbelts alter the PM concentration field within canyons, and the horizontal and vertical distribution characteristics of PM under different wind directions were significantly different.

Effects of functional composition on plant competitors, stress-tolerators, ruderals ecological strategies in forest communities across different climatic zones.

Ecological strategies identified by plant functional traits are valuable descriptors for understanding species, populations, communities, and ecosystems in response to environmental conditions. Ecological strategies, in conjunction with the functional structure of plant communities, serve as crucial tools for investigating complex relationships among the environment, vegetation, and ecosystem functions. However, it remains unclear whether the functional structure (specifically, community-weighted mean [CWM] traits) accurately reflects the optimal ecological strategies in forest communities.
