During the evolution of angiosperm flowers, some floral traits may undergo certain changes in order to participate in screening. The stamens and pistils of Delphinium caeruleum are covered by two “door-like” staminodes, the evolutionary f...
Nectar-robbing insects, which are frequently described as cheaters in plant–pollinator mutualisms, may affect plant reproductive fitness by obtaining nectar rewards without providing pollination services. The negative effects of nectar robbing...
Canna glauca, an ornamental plant widely cultivated in aquatic habitats, is notable for its long florescence and showy flowers. The flower of this species is distinguished by its petaloid staminodes, which comprise the majority of the overall floral...
Angiosperms include many taxa with dimorphic unisexual reproductive structures. These are well studied in some grasses, with maize as a key model, but other wind-pollinated lineages in Poales remain less explored. Within Poales, the family Restionace...
Cacao genotypes propagation through plant tissue culture represents a strategic approach for establishing a core collection of elite plants to be used as a donor material source, necessary for increasing new planting areas of cacao. This study aimed...
To date, in vitro somatic embryogenesis is the only option for the mass vegetative propagation of cocoa. The somatic embryogenesis of Indonesian cocoa clones SUL1 and SUL2 was investigated, focusing on primary and cyclic secondary embryogenesis. The...
The development of an ideal model plant located at a key phylogenetic node is critically important to advance functional and regulatory studies of key regulatory genes in the evolutionary developmental (evo-devo) biology field. In this study, we sele...
The vast majority of highly valuable species of the Leguminosae in temperate latitudes belong to the Inverted Repeat-Lacking Clade (IRLC). Despite having a generally conserved monosymmetric floral morphology, members of this group are remarkable with...
Limestone karst habitats in tropical Asia support specialized and geographically restricted plant diversity, yet many areas remain incompletely explored. During botanical surveys of limestone habitats in northeastern Thailand, a distinctive, yellow-f...
Litsea cubeba (Lour.) Pers., a popular essential oil plant, is a dioecious species with degenerative sexual organs in both male and female individuals. Yet, the mechanism of degenerative organs development in male and female flowers is poorly underst...
Alpinia plants are widely cherished for their vibrant and captivating flowers. The unique feature of this genus lies in their labellum, a specialized floral structure resulting from the fusion of two non-fertile staminodes. However, the intricate pro...
Botanical exploration of northeastern Thailand has revealed substantial undocumented diversity within Typhonium (Araceae). Here, T. boonkerdii Chatan & Promprom is described and illustrated as a new geophytic species from Mukdahan Province. The t...
Typhonium is one of the most species-rich genera of Araceae in tropical Asia, with north-eastern Thailand representing an important but still incompletely documented area of diversity. During botanical surveys in northeastern Thailand, an unusual pop...
Zingiber isanense and Z. baumii were originally distinguished by characters of uncertain stability across natural populations. We reassessed their relationship through field observations, herbarium and protologue comparisons, and phenetic analyses of...
