Genomic methylation patterns in pre-meiotic gynoecia of wild-type and RdDM mutants of Arabidopsis

Frontiers in Plant Science, 2023
IntroductionAlthough DNA methylation patterns are generally considered to be faithfully inherited in Arabidopsis thaliana (Arabidopsis), there is evidence of reprogramming during both male and female gametogenesis.

Eriope barrinhae (Lamiaceae, Hyptidinae), a new montane species from northern Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
In northern Minas Gerais, in the Monte Azul region, the Pico da Formosa mountain remains poorly explored botanically despite recent discoveries of new taxa. During fieldwork at the summit of this mountain, we discovered a distinctive population of Eriope that differs from all known species by a unique combination of morphological characters.

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

Towards an integrated molecular understanding of plant hormones

Journal of Integrative Plant Biology, EarlyView.
This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

Auxin regulation involved in gynoecium morphogenesis of papaya flowers [PDF]

Horticulture Research, 2019
AbstractThe morphogenesis of gynoecium is crucial for propagation and productivity of fruit crops. For trioecious papaya (Carica papaya), highly differentiated morphology of gynoecium in flowers of different sex types is controlled by gene networks and influenced by environmental factors, but the regulatory mechanism in gynoecium morphogenesis is ...

Orchid genome evolution and trait innovation

Journal of Integrative Plant Biology, EarlyView.
Orchids became one of the world's most diverse plant groups through genome‐driven innovations, unique relationships with fungi and pollinators, and remarkable adaptability. This review explains the origins of orchids and the evolution of their distinctive life forms, flowers, and ecological strategies and highlights promising directions for future ...

The multifaceted regulatory network of microRNA396: Orchestrating plant plasticity through coordinating development and various stresses

Journal of Integrative Plant Biology, EarlyView.
This review examines the character and function of the microRNA miR396, which helps plants balance growth, reproduction, regeneration, and survival under various stresses, highlighting recent progress and evidence that this pathway shapes crop yield, pest and disease resistance, and tissue regeneration, making it a promising target for precision crop ...

Refining generic limits in Hyacinthinae (Asparagaceae, Scilloideae): Conflict and concordance between morphology and phylogenomics

Journal of Systematics and Evolution, EarlyView.
Using Angiosperms353 and plastid genome skimming approaches, the generic limits of Hyacinthinae were explored using DNA sequences to better understand their evolution. Floral morphology, a traditional generic delimiter, conflicts with the molecular groupings in many cases, but bulb morphology and cytogenetics define similar groups to DNA.

Trimerous magnoliid flowers with a unique set of floral and pollen traits from the Late Cretaceous of Southern Bohemia (Czech Republic)

New Phytologist, EarlyView.
Morphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...
