Recombination suppression in plant adaptation and speciation

New Phytologist, EarlyView.
Summary Recombination suppression is increasingly recognized as an important facilitator of genomic divergence and speciation, especially under ongoing gene flow. In plants, however, the broader evolutionary consequences and the mechanisms by which recombination suppression arises and spreads are still incompletely understood, reflecting the inherent ...

Arabidopsis acclimation to daily environmental fluctuations converts a defense response regulator into a susceptibility factor toward Sclerotinia

New Phytologist, EarlyView.
Summary Acclimation enables plants to adjust to immediate environmental fluctuations and is therefore key to the resilience of plant disease resistance in a time of climate change. Here, we report on the acclimation of Arabidopsis thaliana quantitative immune responses against the fungal pathogen Sclerotinia sclerotiorum to daily environmental ...

Performance of Indigenous and Introduced Slender Wheatgrass in Alaska, and Presumed Evidence of Ecotypic Evolution [PDF]

, 1991
Objectives of this study were to evaluate forage and seed production, winter hardiness, and stand longevity of several collections of native Alaskan slender wheatgrass (Agropyron trachycaulum (Link) Malte), and to compare their performance with ...

Mitochondrial β‐carbonic anhydrase is a conserved metabolic rheostat for branched‐chain amino acid catabolism and metabolic flexibility

New Phytologist, EarlyView.
Summary Carbonic anhydrases (CAs) are ubiquitous metalloenzymes that catalyze the reversible hydration of CO2, enabling fundamental processes in organisms across all domains of life. Among all CAs, the role of mitochondrial βCA remains poorly understood. Here, we identify a mitochondrial βCA, βCA6, as a key regulator of branched‐chain amino acid (BCAA)

Local adaptation of two cryptic species, Lasthenia californica and Lasthenia gracilis, to distinct regions within a serpentine outcrop [PDF]

, 2013
Intraspecific variation providing tolerance to specific edaphic conditions may contribute to population differentiation, speciation, and species coexistence.

Cold hardiness dynamics predict budbreak and associated low‐temperature threats in grapevine

New Phytologist, EarlyView.
Summary Dormant buds of temperate woody perennial plants must attain cold hardiness to survive winters and timely lose it in spring to break bud while avoiding damage from low temperatures and late frosts. Therefore, we asked: Can a cold hardiness model be used to predict budbreak?

An atlas of plant selenium metabolism

New Phytologist, EarlyView.
Summary Selenium (Se) is not only a rare and toxic element but also an essential micronutrient for humans and animals that is often in short supply. Terrestrial plants do not require Se, but it can have growth‐promoting or negative effects, depending on the exposure level.

Guard cell photorespiration controls stomata behavior and development

New Phytologist, EarlyView.
Summary Photorespiration is traditionally viewed as a limitation to photosynthetic efficiency. However, it is mandatory for safeguarding the Calvin–Benson–Bassham cycle from inhibitory byproducts through Rubisco‐mediated oxidative misfire and is tightly integrated with primary metabolism.

Rare Natural SNP Activates SHOOT APICAL MERISTEM ENLARGER1 to Increase Branch Number and Silique Number on the Main Inflorescence in Brassica napus

Plant Biotechnology Journal, EarlyView.
ABSTRACT Brassica napus is the second most important oil crop worldwide. Number of primary branches (Branch number, BN) and silique number on the main inflorescence (SMI) are key yield‐related quantitative traits. Here, we cloned a major QTL, qDB.A09, which simultaneously influences BN and SMI.

Harnessing Bulk‐Segregant Mapping to Identify Trait‐Associated Genes in the Allopolyploid Model Plant Nicotiana benthamiana

Plant Biotechnology Journal, EarlyView.
ABSTRACT Forward genetics has been instrumental in identifying genes underlying desirable traits, yet its application to polyploid plants, many of which are key agricultural crops, remains challenging due to their genomic complexity. Therefore, we developed BenthMap, a bulk segregant analysis platform for high‐throughput trait mapping and gene ...
