Article Abstract
Orchids comprise one of the largest, most highly evolved angiosperm families, and form an extremely peculiar group of plants. Various orchids are available through traditional breeding and micro-propagation since they are valuable as potted plants and/or cut flowers in horticultural markets. The flowering of orchids is generally influenced by environmental signals such as temperature and endogenous developmental programs controlled by genetic factors as is usual in many flowering plant species. The process of floral transition is connected to the flower developmental programs that include floral meristem maintenance and floral organ specification. Thanks to advances in molecular and genetic technologies, the understanding of the molecular mechanisms underlying orchid floral transition and flower developmental processes have been widened, especially in several commercially important orchids such as , and . In this review, we consolidate recent progress in research on the floral transition and flower development of orchids emphasizing representative genes and genetic networks, and also introduce a few successful cases of manipulation of orchid flowering/flower development through the application of molecular breeding or biotechnology tools.

Flowering is a key trait in most crops and may depend on cold exposure, a process known as vernalization, but the underlying regulatory mechanisms are poorly understood. Taraxacum koksaghyz is a rubber-producing dandelion of the family Asteraceae, which also includes other economically important crops such as chicory and lettuce. Most T.

The coordination of floral developmental stages with the environment is important for reproductive success and the optimization of crop yields. The timing of different developmental stages contributes to final yield potential with optimal adaptation enabling development to proceed without being impacted by seasonal weather events, including frosts or end of season drought. Here we characterise the role of FLOWERING LOCUS T 3 (FT3) in hexaploid bread wheat (Triticum aestivum) during the early stages of floral development.

Chitinases, enzymes responsible for hydrolyzing chitin, a significant component of fungal cell walls, play a crucial role in plant defense mechanisms, growth, symbiotic relationships, and stress resistance. In this study, we identified 27 chitinase genes in chickpeas (CaChi) and classified them into five classes based on phylogenetic analysis. Overall, chitinase genes are clustered on eight chromosomes.

Premise: Transitions from outcrossing to selfing often drive the evolution of floral traits in a predictable way. However, these expectations are not as straightforward for mixed-mating systems. In this study, we examine variation in pollen-collecting hairs, a floral structure involved in secondary pollen presentation within Campanulaceae.

Anthocyanins, crucial water-soluble pigments in plants, determine coloration in floral and fruit tissues, while fulfilling essential physiological roles in terms of plant growth, development, and stress adaptation. The biosynthesis of anthocyanins is transcriptionally regulated by WRKY factors, one of the largest plant-specific transcription factor families. is an East Asian species, prized for its exceptionally persistent butterfly-shaped fruits that undergo pericarp dehiscence, overturning, and a color transition to scarlet red.
