“…WRKY27 is gibberellins-responsive transcription factor (Gu et al 2019). Here and for the rst time we have reported its possible association with SFW and seed germination as gibberellins are intrinsic factors involved in the germination process (Stejskalová et al 2015). Protein kinase APK1B, the other SFW-associated gene, is required for ABA signaling during germination (Fujii et al 2007;He et al 2011).…”

Background Genome-wide association study (GWAS) has become an accepted and powerful method for understanding the associations between phenotypes and genotypes. In agricultural production, uniform and rapid germination is an important prerequisite in crop production. Here, a rice (Oryza sativa L.) GWAS with 33,934 SNPs (MAF > 0.05) for eight germination traits including germination percentage (GP), shoot (SL) and root length (RL), root (RFW) and shoot fresh weight (SFW), root (RDW) and shoot (SDW) dry weight, and number of days to germinate (NDG) was performed to define genomic regions influencing seed germination. Results Loci (43) with 70 significant germination-associated markers were detected across all rice chromosomes. Some of novel candidate associated genes were: LOC_Os01g26210 (OsWAK6) co-located with qGR-1 that is seed vigor QTL, LOC_Os07g23944 (GH31) with an α-glucosidases /starch lyase activity; id7000519 marker that corresponds to a gene cluster containing glutathione S-transferase and glucan endo-1,3-β-glucosidase co-located with qAG3 germination-related marker, LOC_Os06g47640 (calmodulin-related calcium sensor protein 29) involved in the inhibition of ABA during seed germination, and id4006430 marker that corresponds to a gene cluster containing three GH17 hydrolytic enzyme that are co-located with qHD4 and qGI1 markers. Conclusion The germination process is an initial and important step in the production of agricultural products, especially for rice, which is a crop plant that is grown in flooded lands. Here, the genetic diversity of rice genotypes was put under scrutiny for germination. Our GWAS results identified several likely candidate genes for germination traits that will greatly contribute to our understanding of the genetic complexity underlying the corresponding traits. The associated genes with the germination traits can be generally classified as hydrolytic enzymes and regulatory proteins that can directly or indirectly influence germination.

“…The effect of gibberellic acid (GA 3 ), a well-known phytohormone that regulates plant growth, has been rarely studied in industrial hemp, though it has been well studied in other crops [18,20,[41][42][43][44].…”

“…Seed germination and early seedling growth depend on several factors, including varieties with different seed sizes [10][11][12], seed sources [13][14][15] and seed origins [16,17]. They also respond differently to pre-treatments with chemicals, such as plant growth regulators [18][19][20], seed disinfectants [21][22][23][24][25][26][27][28] and cold temperatures [29][30][31][32][33].…”

Seed germination and seedling growth are two essential early determinants of subsequent crop yield and quality. A high germination percentage of industrial hemp (Cannabis sativa L.) seed is required to import into Australia. The viability of hemp seed can decline rapidly depending on storage and other factors; hence, the quality of imported seed is not always reliable. Here, we aimed to investigate germination and early seedling growth responses of 14 industrial hemp varieties after being imported from various countries. Germination trials were conducted with 100 seeds of 14 varieties using a soil-less Petri dish assay and a compost growth medium under glasshouse conditions. We also assessed the effect of seed pre-treatments such as gibberellic acid (500 and 1000 mg·L−1), chlorine dioxide (500 and 1000 mg·L−1) and cold temperature (4 °C for 72 h) using 300 seeds of each of the three selected varieties in compost growth medium. Hemp varieties imported from China had higher germination and better seedling growth indices than those imported from Europe. All seed pre-treatments were associated with a decreasing trend in germination, but a positive effect on early growth responses was observed. Our findings indicate that the hemp variety Han FNQ performed better than many other varieties did regarding seed germination and seedling growth. Hemp seeds sanitising with 500 mg·L−1 of chlorine dioxide might improve the germination and early growth of seedlings.

“…Seeds from each mother tree were germinated separately by placing eight seeds into a 90 mm diameter petri dish on top of two filter papers. Filter papers were soaked with a 200 mg/L of gibberellic acid potassium salt solution [30] and dishes were incubated in a closed box for one month within a 4°C fridge. For three mothertrees, and additional 16 seeds were germinated in the same way.…”

Illegal logging is one of the largest illicit trades in the world, with high profits and generally low risks of detection and prosecution. Timber identification presents problems for law enforcement as traditionally used forensic methods such as wood anatomy and dendrochronology are often unable to confidently match wood evidence to the remains of illegally felled trees. Here we have developed and validated a set of genetic markers for individualisation in bigleaf maple (Acer macrophyllum), a high value timber species often felled illegally in the USA. Using 128 single nucleotide polymorphisms and three insertion/deletion markers developed through massively parallel sequencing, 394 individuals were genotyped on the MassARRAY® iPLEX™ platform (Agena Bio-science™, San Diego, USA) to produce a population reference database for the species. We demonstrate that the resulting DNA assay is reliable, species specific, effective at low DNA concentrations (< 1 ng/μL) and suitable for application to timber samples. The P ID for the most common profile, calculated using an overall dataset level F ST -correction factor, was 1.785 × 10 −25 and P ID-SIB across all individuals (treated as a single population) was 2.496 × 10 -22 . The further development of forensic identification assays for timber species has the potential to deliver robust tools for improved detection and prosecution of illegal logging crimes as well as for the verification of legality in reputable supply chains.
