A cytochrome P450 gene, GmSUR2a, confers submergence tolerance and improves yield in soybean by modulating auxin homeostasis

Journal of Integrative Plant Biology, EarlyView.
The key cytochrome P450 gene GmSUR2a enables soybeans to withstand destructive submergence stress. By lowering the level of the plant hormone indole‐3‐acetic acid, this gene improves soybean survival and increases field yield. It offers an important tool for breeding stress‑resilient soybeans, securing food production against extreme weather conditions.

Auxin response and PIN‐mediated transport in chlorophyte algae

Journal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Phytophthora nicotianae var. nicotianae on tomatoes

Around 1960 some disorders which initially were considered to be of a physiological nature were found in tomato plants grown in glasshouses in the Netherlands. One complex of symptoms was a brown rot of the lateral roots and the tap root, often followed by decomposition of the stem base tissue and death of the plant.

Natural variation in the promoter of OsPDX1.2 enhances vitamin B6 accumulation and cold tolerance in rice

Journal of Integrative Plant Biology, EarlyView.
Allelic variation in the promoter of the pyridoxal phosphate synthase OsPDX1.2 caused variation in the ACE‐box cis‐elements, resulting in differing OsPDX1.2 expression due to differences in binding affinity between the OsbZIP18 transcriptipn factor and the ACE‐box, contributing to variation in vitamin B6 levels and cold tolerance among rice varieties ...

El polen de especies del género Nicotiana (Solanaceae) presentes en Chile: Evaluación de la utilidad de sus caracteres morfológicos como biomarcadores en estudios arqueológicos

Boletín de la Sociedad Argentina de Botánica, 2016
Diversas sociedades americanas prehispánicas han utilizado el tabaco (Nicotiana spp.) en contextos sagrados, medicinales o recreativos. Las especies de Nicotiana contienen nicotina, alcaloide que es ingerido al fumar, masticar o inhalar la planta. El uso

Expression of the PR-b1" gene in the roots of two Nicotiana species and their amphidiploid hybrid infected with virulent and avirulent races of Chalara elegans

, 1993
The expression levels of PR-b1'' gene coding for PR-b1'' protein (a PR-I group protein) were investigated in the roots of two Nicotiana species and their amphidiploid hybrid in response to infection by virulent (84-1) or avirulent (85-26) races of black ...

RING E3 ligase SNIPER8 functions redundantly with three close homologs to regulate the turnover of transcriptional co‐repressor TPR1

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis E3 ligase SNIPER8 negatively regulates immunity by promoting ubiquitination and proteasomal degradation of the transcriptional corepressor TOPLESS‐RELATED1, limiting excessive immune responses, maintaining immune homeostasis, and balancing defense activation and normal plant growth.

PtoHY5 integrates photoperiodic signals with the ABA pathway to coordinate growth cessation and dormancy in Populus

Journal of Integrative Plant Biology, EarlyView.
In Populus, short days deactivate the growth‐promoting protein PtoHY5, turning off a growth accelerator and activating an abscisic acid‐driven brake. This directly couples growth cessation with dormancy, underscoring the role of abscisic acid in synchronizing these transitions for winter survival.
