Saussurea × media (Asteraceae), a new natural hybrid between S. parviflora and S. controversa
Nordic Journal of Botany, EarlyView.Saussurea × media Yusupovsky and E.Pjak (Asteraceae), a new nothospecies from the Altai‐Sayan Mountains, is described and illustrated. In this study, we sequenced the internal transcribed spacer of nuclear ribosomal DNA and the chloroplast intergenic spacers rsp16‐trnQ and ycf4‐cemA to verify the hypothesis of hybridization between Saussurea parviflora

Immunohistochemistry of Gibberellins in Rice Anthers
Bioscience, Biotechnology, and Biochemistry, 1995 A new immunohistochemical method for analyzing the localization of gibberellins was developed and applied to rice anthers. This method uses 1,3-diisopropylcarbodiimide gas fixation to prevent the drift of gibberellins during the fixation procedure. Spikelets before anthesis were frozen in liquid nitrogen and lyophilized.

Nordic Journal of Botany, EarlyView.The circumscription of the Paleotropical dioecious and species‐rich genus Timonius Rumph. ex DC. nom. cons.has long been based on a restricted combination of morphological features, namely valvate corolla aestivation and drupes bearing multiple, free, single‐seeded pyrenes. Previous studies, focused on different taxonomic problems in tribe Guettardeae,

Understanding the role of gibberellin signalling in wheat anther development during heat stress [PDF]
, 2016 High temperature (HT) stress during wheat male reproductive development causes irreversible damage to the anther tapetum layer and the developing microspores it supports, resulting in reduced yield.

Bupleurum oslaense, a new species of Apiaceae from Uttarakhand, Western Himalaya, India
Nordic Journal of Botany, EarlyView.Bupleurum oslaense sp. nov., a new member of the family Apiaceae, is described and illustrated based on the collections from Uttarakhand, India. The species shows close affinity to the Chinese element Bupleurum petiolulatum, but can be readily distinguished by its stout habit, higher number of rays, markedly larger bracts, and greater number of flowers

Nordic Journal of Botany, EarlyView.During a biosystematics study of the Iranian species of the genus Elymus in 2022–2024 a new species for the genus Elymus L. was found in the Arasbaran region of northwest Iran. The new species is morphologically close to Elymus repens and Elymus elongatiformis but differs in terms of inflorescence shape, shape and size of glumes, and characteristics of

Novelties in Dimerostemma (Asteraceae, Heliantheae) from Rio Grande do Sul, Brazil
Nordic Journal of Botany, EarlyView.Revisiting the Dimerostemma collection in Rio Grande do Sul, the southernmost state of Brazil, one new species of Dimerostemma is described and another is resurrected. Although previously synonymized under Dimerostemma arnottii, Dimerostemma oppositifolium is here resurrected based on its distinct opposite leaves, linear to lanceolate leaf limbs, and ...
