Autopolyploidization‐Induced Chromatin Remodeling Regulates Leaf Size Variation in Brassica rapa

open access: yesAdvanced Science, EarlyView.
This study demonstrates that monoploid, diploid, and autotetraploid Brassica rapa lines derived from the same genome exhibit distinct leaf morphology. Ploidy changes remodel chromatin accessibility and histone modifications to regulate gene expression, while key transcription factors BrGRF13 and BrARF11 control leaf size and polarity, driving ...

Multimodal cadmium resistance and its regulatory networking in Pseudomonas aeruginosa strain CD3

open access: yesScientific Reports
Cadmium, a toxic heavy metal, poses significant global concern. A strain of the genus Pseudomonas, CD3, demonstrating significant cadmium resistance (up to 3 mM CdCl2.H2O) was identified from a pool of 26 cadmium-resistant bacteria isolated from cadmium ...

An Anatomically Preserved Cone-like Flower from the Lower Cretaceous of China

open access: yesLife, 2023
Although diverse fossil angiosperms (including their reproductive organs) have been reported from the Early Cretaceous, few of them are well-documented due to poor preservation and limited technologies available to apply. For example, paraffin sectioning,

Gene duplication and an accelerated evolutionary rate in 11S globulin genes are associated with higher protein synthesis in dicots as compared to monocots [PDF]

open access: yes, 2012
Background: Seed storage proteins are a major source of dietary protein, and the content of such proteins determines both the quantity and quality of crop yield.

A Trypsin‐Like Serine Protease ZmNAL1a Fine‐Tunes Maize Floral Transition and Flowering Time

open access: yesAdvanced Science, EarlyView.
This study identifies a trypsin‐like serine protease, ZmNAL1a, that moves from leaves to the shoot apical meristem. ZmNAL1a promotes the floral transition by degrading TOPLESS‐like corepressor REL2, which thereby enhances the expression of key flowering genes through elevating histone acetylation and relieving REL2–ZmEREBP147‐mediated transcriptional ...

Self-pollination by sliding pollen in Caulokaempferia coenobialis (Zingiberaceae) [PDF]

open access: yes, 2005
Caulokaempferia coenobialis (Zingiberaceae) forms dense populations on steep cliffs in shady, humid monsoon forests in south China. It produces few consecutively opening bright yellow flowers that are 3 cm long and oriented parallel to the ground.

Reference‐Guided Chromosome‐by‐Chromosome de novo Assembly at Scale Using Low‐Coverage High‐Fidelity Long‐Reads with HiFiCCL

open access: yesAdvanced Science, EarlyView.
HiFiCCL, as the first assembly framework specifically designed for low‐coverage high‐fidelity reads, improves the assembly quality of existing assemblers and also enhances downstream applications such as large structural variant (SV) detection (>10 000 bp), synteny analysis, pangenome graph construction, and graph‐based individual‐specific germline SVs

Coordination of Foliar and Wood Anatomical Traits Contributes to Tropical Tree Distributions and Productivity along the Malay-Thai Peninsula [PDF]

open access: yes, 2009
Drought is a critical factor in plant species distributions. Much research points to its relevance even in moist tropical regions. Recent studies have begun to elucidate mechanisms underlying the distributions of tropical tree species with respect to ...

Breaking Down Lignin: A Macromolecule's Path to the Nanoscale

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This section highlights lignin's critical role as a sustainable, multifunctional precursor for nanomaterial design. Its unique structure and abundance enable the creation of lignin‐based, lignin‐derived, and hybrid nanomaterials with tunable properties. Emphasis is placed on lignin's potential to drive innovation in nanotechnology, offering ecofriendly
