The inheritance of sex in an abnormal (Carpellodic) wall-flower

open access: yes, 1928
In wall-flower (Cheiranthus cheiri, L.) a curious floral abnormality has long been known. The plant is quite normal until it blooms. In the flower, however, while the sepals are normal the petals are reduced to narrow strips equal in length to the sepals

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

open access: yesAdvanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Interaction between greenhouse grown chrysanthemum and Frankliniella occidentalis [PDF]

open access: yes, 2006
Growers of floricultural crops are still dependent on chemical insecticides because of low consumer tolerance to damaged produce. More knowledge of natural interactions between insects and their host plants would allow insect pests to be controlled in a ...

Homeotic genes controlling flower development in Antirrhinum [PDF]

open access: yes, 1991
In order to study genes controlling flower development, we have carried out an extensive transposon-mutagenesis experiment in Antirrhinum majus. More than 15 independent homeotic mutations were obtained, allowing three categories of genes to be defined ...

Wavy‐Interlocked Stretchable Triboelectric Nanogenerators Enhanced by Liquid Metal Microflowers for Self‐Powered Wearable Motion Monitoring

open access: yesAdvanced Science, EarlyView.
Schematic showing a stretchable triboelectric nanogenerator based on interlocked wavy architectures that uses EGaIn microflower‐embedded PVDF‐TrFE and Nylon‐6 nanofiber membranes. The multi‐petaled, electron‐rich EGaIn microflowers enhance interfacial polarization and capacitance, while the interlocked wavy architecture enlarges the effective contact ...

Determination of internal controls for quantitative gene expression of Spodoptera litura under microbial pesticide stress

open access: yesScientific Reports
Quantitative real-time polymerase chain reaction (qRT-PCR) has become a commonly used method for the quantification of gene expression. However, accurate qRT-PCR analysis requires a valid internal reference for data normalization.

Construction of a Nocturnal Low-Temperature Tolerance Index for Strawberry and Its Correlation with Yield

open access: yesHorticulturae
Strawberry is widely cultivated due to its short growth cycle, high yield, and significant profits. In high-latitude cold regions, the planting area of overwintering strawberry has expanded rapidly in recent years.

Flowers of the field

open access: yes
A keen collector and sketcher of plant specimens from an early age, the author, educator and clergyman Charles Alexander Johns (1811–74) gained recognition for his popular books on British plants, trees, birds and countryside walks. The Forest Trees of Britain (1847–9), one of several works originally published by the Society for Promoting Christian ...

Organoid Brain‐Machine‐Interface Devices for Central Nervous System Repair

open access: yesAdvanced Science, EarlyView.
We envision organoid brain‐machine‐interface (Organoid‐BMI) devices as new biohybrid bidirectional communication pathways to connect the human CNS and the external world for personalized CNS repair and regeneration. ABSTRACT Central nervous system (CNS) repair and regeneration suffer from tremendous clinical challenges due to current limitations in ...
