Initial growth of Megathyrsus maximus cv. Massai grass biostimulated with Burkholderia pyrrocinia at different sowing depths

Acta Scientiarum: Animal Sciences
Sowing depth affects both germination and emergence of seeds. Thus, inoculation with Burkholderia pyrrocinia, a biostimulant, may have positive effects on grass establishment. The aim was to evaluate the effects of inoculation with B.

Sociabilidade de espécies nativas da Mata Atlântica com a exótica invasora Megathyrsus maximus (Jacq.) B.K.Simon & S.W.L.Jacobs

Revista Brasileira de Meio Ambiente, 2021
O processo de invasão biológica ocorre quando uma espécie exótica é introduzida em um ecossistema ao qual não pertence, se adapta e passa a provocar mudanças no mesmo, passando a se chamar de espécie exótica invasora.

Structural and productive responses of signalgrass and its association with leaf area index and light interception under silvopastoral or monoculture systems

Agrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Silvopastoral systems (SPSs) have emerged as one of the most prominent alternatives for grassland recovery. We evaluated the structural and productive responses of signalgrass [Urochloa decumbens (Stapf.) R. D. Webster] and its association with leaf area index (LAI) and light interception (LI) measured with different equipment across different

Species delimitation and molecular dating of southern African Tetramesa (Hymenoptera: Eurytomidae): An understudied microhymenopteran group

Austral Entomology, Volume 64, Issue 2, May 2025.
Abstract The genus Tetramesa Walker (Hymenoptera: Eurytomidae) comprises over 200 species of herbivorous wasps that feed exclusively on grasses. Recent field surveys in South Africa for grass biological control programs have uncovered a large diversity of potential Tetramesa on African grasses.

Islanded Islands: Dual Isolation Drive Distinctive and Threatened Floras of Neotropical Maritime Inselbergs

Journal of Vegetation Science, Volume 36, Issue 3, May/June 2025.
ABSTRACT Questions Inselbergs, isolated rock outcrops, support unique plant communities. Maritime inselbergs (MIs) experience transient isolation due to maritime fluctuations, creating harsh survival conditions. This study is the first to investigate the plant communities' patterns on MIs, comparing them with those on continental inselbergs (CIs).

Ferramentas moleculares no melhoramento genético de Megathyrsus maximus para o semiárido: uma revisão

Research, Society and Development, 2020
A necessidade de ter alimentos à disposição do rebanho, ao longo do ano, gera esforços para desenvolver métodos e técnicas para adaptar forrageiras tropicais a regiões com déficit hídrico. Nessa perspectiva, o objetivo desta investigação foi realizar uma revisão de literatura sobre gramíneas forrageiras da espécie Megathyrsus maximus e ferramentas ...

Effect of Fibrolytic Enzymes and Regrowth Ages on Fermentation Profile and Nutrient Composition of Mombasa Grass and Elephant Grass Silages

Grass and Forage Science, Volume 80, Issue 2, April-June 2025.
ABSTRACT Two experiments were carried out to evaluate whether the addition of cellulase and/or xylanase enzymes interacts with regrowth age (RA) in mombasa grass (Megathyrsus maximus) and elephant grass cv. BRS Capiaçu (Cenchrus purpureus) to alter nutritive composition and fermentation profile. Mombasa and elephant grass plots were mowed and harvested

Yield and Stability of Three Tropical Forage Grasses Cultivated as Pure or Mixed Stands

Grass and Forage Science, Volume 80, Issue 2, April-June 2025.
ABSTRACT Multispecific pastures are considered more sustainable to animal production than monocultures. However, studies on mixtures of tropical grasses are underexplored. We aimed to assess whether a mixture of three contrasting growth strategies of perennial tropical forage grasses could outperform their respective monocultures in terms of forage ...

Genetic engineering of RuBisCO by multiplex CRISPR editing small subunits in rice

Plant Biotechnology Journal, Volume 23, Issue 3, Page 731-749, March 2025.
Summary Ribulose‐1,5‐bisphosphate carboxylase/oxygenase (RuBisCO) is required for photosynthetic carbon assimilation, as it catalyses the conversion of inorganic carbon into organic carbon. Despite its importance, RuBisCO is inefficient; it has a low catalytic rate and poor substrate specificity. Improving the catalytic performance of RuBisCO is one of
