Genome‐wide association and haplotype analyses reveal genetic architecture of seed dormancy in grain sorghum with implications for preharvest sprouting tolerance

open access: yesThe Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Preharvest sprouting (PHS), triggered primarily by wet or humid conditions at maturity and further influenced by temperature, causes premature grain germination in sorghum (Sorghum bicolor (L.) Moench), reducing yield and grain quality. To elucidate the genetic architecture of seed dormancy and germination responses related to PHS tolerance ...

Callose (β-1,3 glucan) is essential for Arabidopsis pollen wall patterning, but not tube growth [PDF]

open access: yes, 2005
Background: Callose (β-1,3 glucan) separates developing pollen grains, preventing their underlying walls (exine) from fusing. The pollen tubes that transport sperm to female gametes also contain callose, both in their walls as well as in the plugs that ...

The tasiR‐ARF pathway in plants: origin, functions, and interplay of miR‐390, tasiRNAs and ARF3

open access: yesPlant Biology, Volume 28, Issue 2, Page 328-344, March 2026.
Trans‐acting small interfering RNAs that silence a subset of Auxin Response Factors are crucial for plant growth, developmental timing, proper organ patterning, and coping with stress. Abstract Trans‐acting small interfering RNA (tasiRNAs) are a special type of endogenous small RNAs (sRNAs) found only in plants.

Begonia chunxiuensis, a new species of Begonia sect. Platycentrum (Begoniaceae) from Guangxi, China

open access: yesNordic Journal of Botany, Volume 2026, Issue 2, February 2026.
Begonia chunxiuensis, a new species from Guangxi of China, is described and illustrated. It is morphologically similar to B. sinovietnamica and B. aurora, but differs from them by its narrowly triangular stipules, leaf blade that is adaxially green, dark green to viridian, pinkish‐white to white villous, but abaxially light green with red veins, red to

A new species of Drimia Jacq. ex Willd. (Asparagaceae) from Nellai wildlife sanctuary, Western Ghats, India

open access: yesNordic Journal of Botany, Volume 2026, Issue 2, February 2026.
The new species Drimia courtallensis from the Nellai Wildlife Sanctuary of Tamil Nadu, India is described and illustrated. It is similar to Drimia razii,in its necked bulb, hysteranthous nature, lax inflorescence and diurnal flowers on moderately short pedicels but it can be distinguished by its broader linear‐lanceolate leaves (230–420 × 6–15 mm ...

Pollen–Pistil Interaction During Distant Hybridization in Plants

open access: yesAgronomy
A combination of high potential productivity and ecological stability is essential for current cultivars, which is achievable by breeding. Interspecific/intergeneric hybridization remains a key approach to producing new high-yielding and resistant ...

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna

open access: yesBiological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...
