“…The date palm (Phoenix dactylifera L.) is a major emblematic food crop of oasis agroecosystems in arid North African and Southwest Asian regions. There are currently over 100 million date palm trees worldwide (Khan et al 2020). Date palms are of major cultural importance and a primary income source in many countries (Hadrami and Al-Khayri 2012), especially in the main producing countries: Egypt, Iran and Saudi Arabia (FAO data, 2021).…”

In arid regions, excessive water use threatens agricultural sustainability and overall livelihoods. It is essential to minimize water consumption to address these issues. Date palm (Phoenix dactylifera L.) is an emblematic crop of arid regions and a major water consumer. Tailoring current irrigation systems into new, water-efficient systems could help cope with the water consumption of this crop. Microbial communities associated with plants are essential for agricultural sustainability and could improve the water use efficiency in regions threatened by water scarcity. These communities should thus be seriously taken into account when adapting agrosystems to the current global change setting. However, no information is presently available on the effects of these modifications on date palm microbial communities. This study highlights the impact of different soil water systems (flooding and drip irrigation, natural conditions and abandoned farms) on date palm root fungal communities at different soil depths. The findings revealed that the soil water systems had a marked impact on fungal communities and that drip irrigation reduced the fungal diversity but increased the abundance of arbuscular mycorrhizal fungi. We showed that these effects were similar at all sampling depths. Finally, as the root architecture is a major determinant of water uptake, we reveal different behaviors of the root architecture under these different soil water systems to 160 cm depth. The findings of this study give new insights into the date palm root architecture and associated fungal communities, particularly in the context of the water availability crisis, which drives the adaptation of agricultural systems.

“…It is presently regarded as the most important agricultural crop [28]. There are 100 million date palm trees in the world [29]. It is well-known for its signi cant nutrients, dietary ber, and natural antioxidants and sources of rich bioactive compounds that are useful in the treatment of neurological diseases and cancer [30].…”

Dates have various minerals and health advantages, however, its major RNA interference (RNAi) genes are not yet studied, though these gene families play a vital role in controlling other protein coding genes. Therefore, we designed this in silico study to explore major RNAi genes highlighting their phylogenetic groups, domains, structures, locations, molecular functions, regulatory factors of date palm. Initially, a BLASTP search on date palm genome governed by the Arabidopsis thaliana RNAi genes (query sequences) predicted 4 DCLs, 7 AGOs, and 3 RDRs genes as key RNAi genes families of date palm. Domain analysis revealed the Helicase_C, Dicer_dimer, PAZ, RNase III, and Piwi domains of projected RNAi genes that are associated with the gene silencing pathways. The majority of expected RNAi was found in the nucleus, which is important site of gene silencing actions. The gene ontology (GO) enrichment analysis revealed some important molecular functions (MFs) and biological processes (BPs) including RNA interference that were related to the predicted RNAi genes which directly involved in the gene silencing mechanism. Gene regulatory network (GRN) analysis identified some important transcription factors including PAZ, and SNF2 involved in RNAi techniques and micro RNAs (miRNAs) including Pda-MIR156b, Pda-MIR396a, Pda-MIR166a, Pda-MIR167d, Pda-MIR395e, Pda-MIR529a associated with biotic/abiotic stress tolerance and developments, as transcriptional and post-transcriptional regulators of RNAi genes. The cis-acting regulatory element analysis suggested some vital cis-acting elements (as-1, ABRE, MBS, MYB, MYC, Box-4, G-box, I-box, STRE) that linked with the predicted RNAi as different abiotic stresses. Therefore, the findings of this study would be useful resources for further research to improve the date palm production.

“…As one of the largest economies in recent years, the wood composite industries particularly the wood‐based panel have brought forward a new impetus. [ 1 ] Wood product industries widely use the aldehydes adhesives (including phenol‐formaldehyde (PF), urea‐formaldehyde (UF), and melamine formaldehyde adhesives) in the manufacturing process. Among them, the phenolic resin adhesive is most widely used due to the advantages of high adhesive strength, good water resistance, and good heat resistance.…”

Replacing petroleum-based chemicals with biomass-based alternatives is becoming more and more important for the development of a low-carbon economy around the world. The latest life cycle assessment displayed that partially replacing phenol with biobased lignin in the process of synthesizing phenolic resin adhesives used in wood panels industry can remarkably reduce carbon emissions and negative environmental impact. The macromolecular structure of lignin is similar to that of phenolic resin and the basic structure unit is similar to that of the phenol, thus endowing it with the potential to substitute phenol and reduce the release of formaldehyde in the preparation process of phenolic resin. Importantly, the lignin-based adhesive exhibits improved performance and reduced cost compared with the petroleum-based adhesive due to the reduced adding amount of petroleum-based volatile components. However, the intrinsic large steric hindrance, structural heterogeneity, and low activity of the natural lignin limit its further application in the adhesive. Many researchers have developed the activation methods such as physical modification, chemical modification, and biological modification to overcome these issues. The different modification of the lignin and their application in the adhesive area are mainly summarized here. Besides, the modification methods and the curing mechanism are also discussed.
