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

Cytoskeleton, Volume 83, Issue 6, Page 337-353, June 2026.
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.

In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

Cytoskeleton, Volume 83, Issue 6, Page 394-406, June 2026.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Elsholtzia yajiangensis (Lamiaceae), a New Species From Sichuan, China

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Adds to the understanding of species diversity in the taxonomically challenging genus Elsholtzia, particularly in the biodiversity hotspot of the Hengduan Mountains. Demonstrates the utility of combining shallow whole‐genome sequencing and morphometrics in resolving species boundaries in closely related shrubby taxa.

Taxonomic Updates of Thismia pseudomelanomitra (Thismiaceae) Reveal an Old Acquaintance From the Ecuadorian Amazon

Feddes Repertorium, Volume 137, Issue 2, June 2026.
ABSTRACT The Amazon Basin is home to the world's greatest terrestrial biodiversity, but many plant groups remain poorly studied. One example is the mycoheterotrophic genus Thismia (Thismiaceae), which is notable for its highly specialized floral morphology and ephemeral life cycles, making it difficult to detect in the field and limiting its ...

A New Species of Myriopus (Heliotropiaceae) From Brazil

Feddes Repertorium, Volume 137, Issue 2, June 2026.
ABSTRACT A new species of Myriopus (Heliotropiaceae), Myriopus chrysocalyx J.I.M. Melo & L.G. Sá, hitherto recorded for the Brazilian Northeastern is described and illustrated. Myriopus chrysocalyx can be readily recognized by its branches strigose to villous, and, mainly, for presenting leaf blade chartaceous to subfleshy, congested inflorescences, a ...

Boron deficiency responses in maize (Zea mays L.) roots

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 3, Page 315-329, June 2026.
Abstract Background Boron (B) is an essential micronutrient for plants. Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize (Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet.

Borax Promotes Fertility of Brassica napus Better Than Other Boron Species at Suboptimal Supply

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 3, Page 362-375, June 2026.
ABSTRACT Background Continuous and sufficient boron (B) supply is essential for achieving maximum yield in Brassica napus. Increasing incidences of environmental water limitation are linked to reduced plant B availability and increased B deficiencies.

Variation in pollen limitation among reproductive modules points to likely resource reallocation in the alpine plant Veratrum grandiflorum

Nordic Journal of Botany, Volume 2026, Issue 6, June 2026.
Pollen limitation, a decrease in seed production due to insufficient pollen receipt, may influence plant demography and the evolution of sexual systems. Its empirical estimation of pollen supplementation of some of the flowers on an individual is well known to be prone to overestimation due to potential resource reallocation among the individual's ...

Adaptive floral traits that impact stigma pollen load and seed production in Penstemon digitalis (Plantaginaceae)

Nordic Journal of Botany, Volume 2026, Issue 6, June 2026.
Penstemon digitalis is an early spring‐flowering species of the northwest Missouri prairie community, a period often characterized by low and unpredictable bee visitation. We conducted an experimental field study to evaluate how pollinator‐mediated pollen transfer and floral longevity interact to influence pollen acquisition and seed production.
