Mind maps for eliciting and assessing plant awareness: A preliminary study on pre‐service teachers
PLANTS, PEOPLE, PLANET, EarlyView.Teachers play an indispensable role in promoting citizens' plant awareness. To this end, they need adequate plant knowledge –including classification–, experience in out‐of‐classroom settings, and enthusiasm for plants. With the aim of improving pre‐service teachers' plant awareness, we designed and implemented a didactic sequence including several ...

5 Petal and Stamen Development
, 1998 Analyses of petal and stamen development are beginning to illuminate the molecular genetic processes that are required to elaborate these organ types. Floral homeotic genes are required to specify certain organ identities, and these functions also are required throughout organogenesis.

"Carpelloid stamens" in Lotus sp.
Acta Societatis Botanicorum Poloniae, 2014 The anatomy and cytology of flower buds in which one or two stamens underwent modifications of various degree, termed in the teratological terminology "carpelloid stamens" were analysed in <em>Lotus</em>. It is presumed that these disturbances were due to the hybrid character of the studied plants.

Loss of YABBY2-Like Gene Expression May Underlie the Evolution of the Laminar Style in Canna and Contribute to Floral Morphological Diversity in the Zingiberales. [PDF]
, 2015 The Zingiberales is an order of tropical monocots that exhibits diverse floral morphologies. The evolution of petaloid, laminar stamens, staminodes, and styles contributes to this diversity.

PLANTS, PEOPLE, PLANET, EarlyView.Understanding plant reproductive strategies is vital for conserving endangered species. This study reveals a novel self‐pollination mechanism in the diminutive orchid Stigmatodactylus sikokianus, facilitated by the movement of a finger‐like appendage beneath the stigma.

Small Structures, EarlyView.MXene oxide–based translucent bilayered coatings on wood exhibit excellent fire resistance, rapid fire response (≈2.9 s), long alarm duration (>300 s), and over 30 cycles of fire‐alarm capability even after 1 year outdoors. The coatings feature tunable transparency, good mechanical properties, and provide a novel strategy for fire‐retardant MXene ...

Cytological characterization and allelism testing of anther developmental mutants identified in a screen of maize male sterile lines. [PDF]
, 2013 Proper regulation of anther differentiation is crucial for producing functional pollen, and defects in or absence of any anther cell type result in male sterility.
