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.

Structure of nectaries of Malus sylvestris (L.) Mill.
Acta Agrobotanica, 2012 The structure of floral nectary of Malus sylvestris was examined using light and scanning electron microscopy. Nectaries in M. sylvestris flowers were situated on the adaxial surface of the receptacle, between the style and the base of filaments.

Calyx and epicalyx morphology in Indian Hibiscus (Malvaceae) and its taxonomic importance
Nordic Journal of Botany, EarlyView.Hibisceae is one of the largest tribes in Malvaceae, having a diverse floral morphology. The genus Hibiscus shows a wide range of evolutionary patterns in calyx and epicalyx morphology. Genera like Abelmoschus, Azanza, Gossypium, Hibiscus,and Thespesia are separated on the basis of calyx and epicalyx morphology, meaning that the calyx and epicalyx have

Floral biological investigations of apple cultivars in relation to fire blight
International Journal of Horticultural Science, 2004 Floral activity was studied in two apple cultivars: an Erwinia-tolerant (Treedorn') and a sensitive one (`Sampion'). Since more types of protogyny occur in apples, the period of stigma activity is different.

Morphological Diversity and Relationships in the A-Genome Cottons, Gossypium arboreum and G. herbaceum [PDF]
, 1994 The Asiatic or A-genome cottons, Gossypium arboreum L. and G. herbaceum L., are potentially important genetic resources for cotton breeding programs. The National Plant Germplasm System (NPGS) contains approximately 400 accessions of these species, but ...

PLANTS, PEOPLE, PLANET, EarlyView.The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

PLANTS, PEOPLE, PLANET, EarlyView.Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.
