Abstract:

Plant protoplasts are significant for plant cell culture, somatic cell fusion, genetics, and breeding studies. In addition, in vitro plant regeneration has great importance for developmental biology, manifesting potential applications in agriculture and biotechnology. In this regard, we present a well-established protocol regarding protoplast isolation, cell culture and protoplast fusion of Jasminum spp. In particular, different tissues of Jasminum samab L. and Jasminum mesnyi were employed for protoplast isolation, and stem explants provided a high callus induction rate in a short period of t

Abstract:

Plant-associated microbiomes have been suggested as pivotal for the growth and health of natural vegetation and agronomic plants. In this sense, plant-associated microbiomes harbor a huge diversity of microorganisms (such as bacteria and fungi) which can modulate the plant host response against pathogens and changing environmental conditions through a complex network of genetic, biochemical, physical, and metabolomics interactions. Advances on next-generation omic technologies have opened the possibility to unravel this complex microbial diversity and their interactive networks as never descri

Abstract:

Abstract The downside risk of crop production affects the entire supply chain of the agricultural industry nationally and globally. This also has a profound impact on food security, and thus livelihoods, in many parts of the world. The advent of high temporal, spatial and spectral resolution remote sensing platforms, specifically during the last 5 years, and the advancement in software pipelines and cloud computing have resulted in the collating, analysing and application of ‘BIG DATA’ systems, especially in agriculture. Furthermore, the application of traditional and novel computational and m

Abstract:

In April 2014, Phytophthora ramorum (Werres, De Cock & Man in't Veld) was recovered from symptomatic foliage of cherry laurel (Prunus laurocerasus) at an ornamental plant nursery in Washington State. Cherry laurel, also known as English laurel, is widely propagated in WA because it is commonly used in landscaping. It is invasive in forests near the urban/wildland interface in the western US and in Europe (Rusterholz et al. 2018). Given its popularity as an ornamental species, the potential of this host to spread P. ramorum is of regulatory concern due to possible long distance spread to ot
