Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status

open access: yesNordic Journal of Botany, EarlyView.
Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

Genetic Diversity and Phylogenetic Analyses of Turkish Cotton (Gossypium hirsutum L.) Lines using ISSR Markers and Chloroplast trnL-F Regions

open access: yesJournal of Natural Fibers, 2022
In this study, genetic diversity and phylogenetic relationships of 22 cotton (Gossypium hirsutum L.) lines widely cultivated in Turkey were investigated. For this purpose, 20 ISSR primers were used, and five of which generated amplification products. The

Rediscovery of Passiflora clypeophylla (subgenus Decaloba): a highly threatened and narrow endemic species found within a karstic canyon in Guatemala

open access: yesNordic Journal of Botany, EarlyView.
Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a

The Contributions of Neotropical Tree Families to the Structure of Common Amazon Forest-Types

open access: yesInternational Journal of Plant Biology, 2023
In order to investigate how familial biodiversity structures forests in the critically important Amazon, I combined past plot samplings to investigate the contributions of tree families in those samplings to the structure of common Amazon forest types. I

Calyx and epicalyx morphology in Indian Hibiscus (Malvaceae) and its taxonomic importance

open access: yesNordic 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

Cytochemical localization of H2O2 in pigment glands of cotton (Gossypium hirsutum L.)

open access: yesJournal of Integrative Agriculture, 2016
Programmed cell death (PCD) plays a critical role in the development of plant pigment glands, while H2O2, which is a kind of reactive oxygen species (ROS) produced by the aerobic metabolism of cells, acts as an important signal in this process.

Leveraging machine learning and citizen science data to describe flowering phenology across South Africa

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Recent shifts in flowering times are an index of, and a response to, human driven climate change. However, most information on these flowering changes is heavily skewed to the northern hemisphere. This imbalance limits our understanding of how climate change is affecting ecosystems, including the mismatches of flowering times between species, increased

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.
