Jasmonate biosynthesis regulates key events in barley vegetative and reproductive development

open access: yesNew Phytologist, EarlyView.
Generation and general phenotypes of hvaoc mutants. Summary Cereal grain is a global food staple. Filial tissues in grain, such as the embryo and endosperm, grow embedded in the maternal ovule and surrounding ovary wall. Maternal tissues provide nutrition and protection but are progressively reduced and degraded as filial tissues expand, driving grain ...

Easy Access to γ-Iodo-gem-Diborylated-Cyclopentanes and Bicyclic Cyclopropanes [PDF]

open access: yes
A formal atom transfer radical [3+2] annulation (ATRAn) reaction between different homoallyl radical precursors and 1,1-diborylethene was developed. It provides a rapid access to polysubstituted cyclopentanes containing a gem-diboronic ester moiety.

Hydroxamic Acids as HDAC Inhibitor Drug Leads for Malaria

open access: yesMedicinal Research Reviews, Volume 46, Issue 6, Page 1477-1498, November 2026.
ABSTRACT Malaria is a global health threat, with an estimated 282 million cases and 610,000 malaria‐associated deaths reported in 2024. Most mortality is due to infection by Plasmodium falciparum parasites, with the highest burden occurring in Sub‐Saharan Africa.

FORMATION OF HIGHLY SUBSTITUTED CYCLOPENTANES FROM RADICAL AND ANIONIC MICHAEL CYCLIZATIONS OF ALPHA-IODO-GAMMA-LACTONES AND ALPHA-IODO-DELTA-LACTONES

open access: yes, 1994
α-Iodo-δ- and -γ-hexonlactones with α,β-unsaturated esters developed from C-6 undergo both tributyltin hydride-induced radical and base catalysed anionic Michael cyclisations to form bicyclic lactones with very highly substituted homochiral cyclopentanes.
