Somatic embryogenesis is a useful tool for plant propagation and consists of a good model for embryo development studies. During somatic embryogenesis, some morphological and biochemical changes occur in response to alterations in gene expression patterns. The somatic embryogenesis receptor kinase (SERK) gene is an important element related to this process. In this work we have focused on the function of SERK in Theobroma cacao. Our main questions were whether this gene exists in this plant with another arrangement; if it is functional and, in a positive case, in which tissues it acts. We have found only one copy of SERK that is functional and analyzed its expression in a series of tissues. The phylogenetic tree showed that the available sequences of SERK are highly conserved and a considerable number of species contain different sequences of SERK, confirming it as a gene family with variant repeats.

The invasion of jumping worms, a small group of pheretimoid earthworm species from Asia, has increasingly become an ecological, environmental and conservation issue in forest ecosystems and urban suburban landscapes around the world. Their presence is often noticed due to their high abundance, distinctive ??jumping?? behavior, and prominent granular casts on the soil surface. Although they are known to affect soil carbon dynamics and nutrient availability, no single paper has summarized their profound impacts on soil biodiversity, plant community, and animals of all trophic groups that rely on soil and the leaf litter layer for habitat, food, and shelter. In this study, we summarize the biology, invasion, and ecological impacts of invasive jumping worms across North America. We highlight potential impacts of this second wave of earthworm invasion, contrast them with the preceding European earthworm invasion in temperate forests in North America, and identify annual life cycle, reproductive and cocoon survival strategies, casting behavior and co-invasion dynamics as the key factors that contribute to their successful invasion and distinct ecological impacts. We then suggest potential management and control strategies for practitioners and policy makers, underscore the importance of coordinated community science projects in tracking the spread, and identify knowledge gaps that need to be addressed to understand and control the invasion. |
