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 ...

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.

New Phytologist, EarlyView.Cuscuta reflexa infection sites. Summary Cuscuta species are holoparasitic plants that penetrate host stems with haustoria, connect to the vasculature and exhaust water, nutrients and carbohydrates. Parasite seedlings possess only limited maternal reserves and the development of a vascular connection takes several days.

Early evolutionary history of the seed. [PDF]
Biol Rev Camb Philos SocABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

New Phytologist, EarlyView.Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

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 ...

Pollen longevity and viability dataset: an integrated resource for plant research and conservation
New Phytologist, EarlyView.The most common methods to estimate pollen viability. Summary Pollen viability and longevity are key traits in plant reproduction, with implications for gene flow, crop breeding, and ex situ plant conservation. However, published data on these traits remain dispersed across disciplines, languages, and methods, limiting their accessibility and reuse ...

A Novel AP2/ERF Transcription Factor Controls Trichome Initiation and Fruit Development in Cucumber
Plant Biotechnology Journal, EarlyView.ABSTRACT Trichomes, the hair‐like outgrowths of the plant epidermis, are critical for defence, reproduction and development. However, the underlying molecular mechanisms governing their initiation remain elusive. Here, we identified CsGL2, an AP2/ERF transcription factor, as a key integrator controlling trichome initiation and fruit development in ...

Natural Variation in GmSL20 Improves Seed Size and Quality in Soybean
Plant Biotechnology Journal, EarlyView.ABSTRACT Seed size plays an important role in determining crop yield, yet the genetic mechanisms underlying the regulation of this agronomic trait remain incompletely understood in soybean. Here, we perform a genome‐wide association study mapping with seed length variations and identify a major quantitative trait locus (QTL) on chromosome 20, named ...
