Abstract:
... Yellow seed trait is a desirable characteristic with potential for increasing seed quality and commercial value in rapeseed, and anthocyanin and proanthocyanidins (PAs) are major seed-coat pigments. Few transcription factors involved in the regulation of anthocyanin and PAs biosynthesis have been characterized in rapeseed. In this study, we identified a transcription factor gene BnbHLH92a (BnaA06T ...

Abstract:
... Climate change can affect tree recruitment altering post-dispersal seed fates and impairing seedling development, and these effects will be stronger at man-disturbed areas than beneath forest canopies. Seed biomass, however, positively influences tree recruitment processes and its relevance increases with environmental harshness. Therefore, this seed trait may become critical for forest regenerati ...

Abstract:
... The landing position of rapeseed distributed from a centralised seed metering system directly affects seeding quality. However, the mechanisms involved in interaction between seeds and tubes are unclear. This study examined parts of the seeding process that are unmeasurable based on DEM simulation and used bench tests to determine seed distribution uniformity. The effects of the type and diameter ...

Abstract:
... Cytosine base editors (CBEs) are great additions to the expanding genome editing toolbox. To improve C‐to‐T base editing in plants, we first compared seven cytidine deaminases in the BE3‐like configuration in rice. We found A3A/Y130F‐CBE_V01 resulted in the highest C‐to‐T base editing efficiency in both rice and Arabidopsis. Furthermore, we demonstrated this A3A/Y130F cytidine deaminase could be u ...

Abstract:
... Pumpkin seeds are used globally for snacks, bakery, and oil due to their nutritional and medicinal properties. The seeds of pumpkin have 35–45% oil, rich in health-enhancing fatty acids especially linoleic (52.7%), oleic (28.3%), and palmitic (12.7%). However, the presence of thick leathery seed coat (hull) limits the use due to decortication process required for further use. A mutant carrying thi ...

Abstract:
... Coexisting plant species often share the same animal mutualists and enemies. The selection preference of an animal on a focal individual is not only directly affected by the focal individual’s intrinsic traits, but also indirectly affected by conspecific or interspecific neighbouring individuals. Many studies often show inconsistent neighbour effects by comparison of the results between the presen ...

Abstract:
... Seeds play a major role in plant species persistence and expansion, and therefore they are essential when modeling species dynamics. However, homogeneity in seed traits is generally assumed, underestimating intraspecific trait variability across the geographic space, which might bias species success models. The aim of this study was to evaluate the existence and consequences of interpopulation var ...

Abstract:
... Seed dispersal is a key process affecting the structure, composition and spatial dynamics of plant populations. Numerous plant species in the tropics rely upon animals to disperse their seeds. Humans have altered mammalian movements, which will likely affect seed dispersal distances (SDD). Altered SDD may have a range of consequences for plant communities including reduced seedling recruitment and ...

Although dispersal is critical to plant life history, the relationships between seed traits and dispersal success in animal-dispersed plants remain unclear due to complex interactions among the effects of seed traits, habitat structure, and disperser behavior. We propose that in plants dispersed by scatter-hoarding granivores, seed trait evolution may have been driven by selective pressures that a ...

Abstract:
... Phytic acid is a ubiquitous compound that chelates the micronutrients in food and hinder their absorption. Hence, breeding for low phytate content for producing stable low phytic acid (lpa) hybrids is essential. Phytic acid content in maize grains has been found to vary across environments and its stable expression has yet to be explored. In a view of this, forty inbreds were screened with two che ...
