We describe three new species of Dixella Dyar & Shannon: Dixella moultoni sp. nov., Dixella jailtoi sp. nov., and Dixella spinosa sp. nov., and record Dixella limai (Santos, 1940) and Dixella trinitensis (Lane, 1943) from the state of Santa Catarina, Brazil. The new species can be distinguished by coloration of the thorax and morphology of the male and female terminalia (except Dixella jailtoi, the female of which is unknown). This represents the first record of Dixidae for Santa Catarina, as well as for the Southern Region of Brazil. An identification key as well as distribution map for these species are provided.

Genomic DNA methylation patterns play a crucial role in the developmental processes of plants and mammals. In this study, we aimed to investigate the significant effects of epigenetic mechanisms on the development of soybean seedlings and metabolic pathways. Our analyses show that 5-azaC-treatment affects radicle development from two Days After Imbibition (DAI), as well as both shoot and root development.

In plant tissue culture, differences in endogenous levels of species-specific plant growth regulators (PGRs) may explain differences in regenerative capacity. In the case of polyamines (PAs), their dynamics and distribution may vary between species, genotypes, tissues, and developmental pathways, such as sexual reproduction and apomixis. In this study, for the first time, we aimed to assess the impact of varying endogenous PAs levels in seeds from distinct reproductive modes in Miconia spp.

Article Synopsis
- Sex segregation in plant propagation raises production costs, making in vitro clonal techniques particularly useful for hermaphroditic plants.
- The study analyzed the proteome of calli from zygotic embryos treated with a plant growth hormone to understand key proteins involved in callus formation over 21 days.
- Results showed distinct patterns in protein accumulation, with certain proteins related to seed maturation decreasing while others tied to metabolism and hormone response increased, highlighting their roles in establishing embryogenic competence.
