TaRIP2 Positively Regulates Wheat Pollen Wall Formation Through MYB80‐Controlled Lipid Metabolism

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 2595-2606, April 2026.
ABSTRACT Male‐sterile genes and mutants are critical for hybrid seed production in monocotyledonous crops. Lipids are essential structural components of male reproductive organs, such as the anther and pollen. Here, we show that the pollen‐preferential gene TaRIP2 is essential for wheat anther development and pollen formation. RT‐qPCR analysis revealed

3‐Methyl‐1‐Butanol Enhances Postharvest Resistance of Red Grapes to Botrytis cinerea by Activating Phenylpropanoid Metabolism and Antioxidant Defences

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 2673-2684, April 2026.
ABSTRACT Grey mould, caused by Botrytis cinerea, is a significant postharvest disease leading to substantial economic losses in the grape industry. This study investigated the regulatory mechanism of 3‐methyl‐1‐butanol (3M1B), a yeast volatile substance, on B. cinerea resistance in red grapes (Vitis vinifera L.).

Auxin‐Induced Nicotine Inhibition Is Mediated by NaARF5 Through the Suppression of NaERF1‐Like Expression and Interaction With NaERF1‐Like in Nicotiana attenuata

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 2642-2656, April 2026.
ABSTRACT Nicotine is the most abundant alkaloid produced by Nicotiana species against insect herbivores. Although it has been known for decades that auxin can strongly inhibit nicotine biosynthesis, the underlying mechanisms have remained unclear.

Forward genetic screening of mutants of the wild diploid ancestor Nicotiana sylvestris identifies aspartate oxidase 2 as a key gene for nicotine biosynthesis in cultivated allotetraploid tobacco (Nicotiana tabacum)

open access: yesThe Plant Journal, Volume 126, Issue 1, April 2026.
SUMMARY Tobacco (Nicotiana tabacum) is one of the most important commercial crops. It is an allotetraploid with two subgenomes derived from two wild diploid species: the maternal ancestor Nicotiana sylvestris and the paternal ancestor Nicotiana tomentosiformis.

Identification of symbiotic nitrogen fixation‐modulating factors in alfalfa and mechanism elucidation of MsHHO3

open access: yesThe Plant Journal, Volume 126, Issue 1, April 2026.
SUMMARY Symbiotic nitrogen fixation (SNF), a unique nitrogen acquisition mechanism formed through the interaction between leguminous plants and rhizobia, plays a critical role in reducing dependence on chemical fertilizers. However, in alfalfa (Medicago sativa L.), the mechanisms underlying nitrate‐responsive SNF remain poorly understood. In this study,
