Influence of Drying Methods on the Phenolic Content and Antioxidant Properties of Crocus sativus L. Tepals and Leaves By‐Products From Meknes (Morocco)

Chemistry &Biodiversity, EarlyView.
ABSTRACT In recent years, much research has focused on the valorization of Crocus sativus by‐products as sources of bioactive compounds. This study was designed to investigate the impact of two different drying methods, freeze‐drying and air‐drying, on the phenolic content and antioxidant activity of leaves and tepals by‐products from C.

PIP1 and PIP2 aquaporins are differentially expressed during tobacco anther and stigma development.

Journal of Experimental Botany, 2004
Several processes during sexual reproduction in higher plants involve the movement of water between cells or tissues, such as occurs during dehiscence of the anther and hydration of the pollen grain after it is deposited on a stigma.

Reproductive success through high pollinator visitation rates despite self incompatibility in an endangered wallflower [PDF]

, 2016
PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

Stigma behavior in Mimulus aurantiacus (Scrophulariaceae).

American-Eurasian journal of botany, 1999
The bilobed stigma of many species in the order Scrophulariales closes in response to touch by an animal pollinator. In hummingbird-pollinated bush monkey flower, Mimulus aurantiacus (Scrophulariaceae), closure is rapid, occurring within seconds of ...

Garcinia kusumae (Clusiaceae): A New Species From Assam, India

Feddes Repertorium, EarlyView.
ABSTRACT A new species, Garcinia kusumae (Clusiaceae), is described and illustrated from Assam, India. Detailed comparisons with morphologically similar species are provided to support its novelty. This discovery contributes to the underexplored diversity of Garcinia in Northeast India and highlights the importance of continued botanical exploration in

Description of pistillate flowers and conservation status of two species of Mollinedia (Monimiaceae, Laurales) from the Brazilian Atlantic forest

Nordic Journal of Botany, EarlyView.
Mollinedia is one of the richest genera of Monimiaceae, with approximately 60 species. In Brazil, 46 species of the genus occur, most of them in the Atlantic Forest. Mollinedia dolichotricha and Mollinedia ruschii are species endemic to the Atlantic Forest and described in the last decade.

Stigma closure and re-opening in Oroxylum indicum (Bignoniaceae): Causes and consequences.

American-Eurasian journal of botany, 2010
The study of plant responses to touch, particularly the responses of leaves, stems, and roots, has a long history. By contrast, floral responses are relatively unexplored.

Reproductive systems of Hohenbergia Schult. & Schult.f. (Bromelioideae: Bromeliaceae) endemic to the Atlantic forest

Nordic Journal of Botany, EarlyView.
Many species of the Bromeliaceae are under threat due to the fragmentation and anthropogenic pressure affecting the Atlantic Forest highlight the need to conservation efforts. The genus Hohenbergia deserves special attention in this context, as the Hohenbergia stellata complex includes endemic species that rely on diverse reproductive strategies, which
