The response of vegetation to climate change has implications for the carbon cycle and global climate. It is frequently assumed that a species responds uniformly across its range to climate change. However, ecotypes − locally adapted populations within a species − display differences in traits that may affect their gross primary productivity ( To determine if ecotypes are important for understanding the response of ecosystem productivity to climate we measured and modeled growing season Transplanted northern ecotypes displayed home‐site advantage in The results demonstrate that ecotypic differentiation can impact the morphology and function of vegetation with implications for carbon cycling. Moreover they suggest that ecotypic control of

Summary GPP ) and response to climate change.GPP in reciprocally transplanted and experimentally warmed ecotypes of the abundant Arctic sedgeEriophorum vaginatum .GPP that was associated with differences in leaf area index. Southern ecotypes exhibited a greater response inGPP when transplanted.GPP may limit the response of ecosystem productivity to climate change. This investigation shows that ecotypes play a substantial role in determiningGPP and its response to climate. These results have implications for understanding annual to decadal carbon cycling where ecotypes could influence ecosystem function and vegetation feedbacks to climate change. -
Summary Actin filament assembly in plants is a dynamic process, requiring the activity of more than 75 actin‐binding proteins. Central to the regulation of filament assembly and stability is the activity of a conserved family of actin‐depolymerizing factors (
ADF s), whose primarily function is to regulate the severing and depolymerization of actin filaments. In recent years, the activity ofADF proteins has been linked to a variety of cellular processes, including those associated with response to stress. Herein, a wheat gene,ADF Ta was identified and characterized.ADF 4,Ta encodes a 139‐amino‐acid protein containing five F‐actin‐binding sites and two G‐actin‐binding sites, and interacts with wheat (ADF 4Triticum aestivum ) Actin1 (TaACT 1),in planta . Following treatment of wheat, separately, with jasmonic acid, abscisic acid or with the avirulent race,CYR 23, of the stripe rust pathogenPuccinia striiformis f. sp.tritici , we observed a rapid induction in accumulation ofTa ADF 4mRNA . Interestingly, accumulation ofTa ADF 4mRNA was diminished in response to inoculation with a virulent race,CYR 31. Silencing ofTa resulted in enhanced susceptibility toADF 4CYR 23, demonstrating a role forTa in defense signaling. Using a pharmacological‐based approach, coupled with an analysis of host response to pathogen infection, we observed that treatment of plants with the actin‐modifying agent latrunculin B enhanced resistance toADF 4CYR 23, including increased production of reactive oxygen species and enhancement of localized hypersensitive cell death. Taken together, these data support the hypothesis thatTa ADF 4 positively modulates plant immunity in wheat via the modulation of actin cytoskeletal organization. -
Premise Despite myriad examples of local adaptation, the phenotypes and genetic variants underlying such adaptive differentiation are seldom known. Recent work on freezing tolerance and local adaptation in ecotypes of
Arabidopsis thaliana from Italy and Sweden provides an essential foundation for uncovering the genotype–phenotype–fitness map for an adaptive response to a key environmental stress.Methods We examined the consequences of a naturally occurring loss‐of‐function (
LOF ) mutation in an Italian allele of the gene that encodes the transcription factor which underlies a major freezing‐tolerance locus. We used four lines with a Swedish genetic background, each containing aCBF 2,LOF allele. Two lines had introgression segments containing the ItalianCBF 2 allele, and two contained deletions created usingCBF 2CRISPR ‐Cas9. We used a growth chamber experiment to quantify freezing tolerance and gene expression before and after cold acclimation.Results Freezing tolerance was lower in the Italian (11%) compared to the Swedish (72%) ecotype, and all four experimental
CBF 2LOF lines had reduced freezing tolerance compared to the Swedish ecotype. Differential expression analyses identified 10 genes for which allCBF 2LOF lines, and theIT ecotype had similar patterns of reduced cold responsive expression compared to theSW ecotype.Conclusions We identified 10 genes that are at least partially regulated by
that may contribute to the differences in cold‐acclimated freezing tolerance between the Italian and Swedish ecotypes. These results provide novel insight into the molecular and physiological mechanisms connecting a naturally occurring sequence polymorphism to an adaptive response to freezing conditions.CBF 2 -
We synthesized Mo(
NC 6F5)(CHCM e2Ph)(TPPO )(PP hMe2)Cl (TPPO = 2,3,5,6‐tetraphenylphenoxide), Mo(NC 6F5)(CHCM e2Ph)(TTBTO )(PP hMe2)Cl (TTBTO = 2,6‐di(3′,5′‐di‐tert ‐butylphenyl)phenoxide), and Mo(NC 6F5)(CHCM e2Ph)(TPPO )(PP hMe2)(CF 3Pyr) (CF 3Pyr = 3,4‐bistrifluoromethylpyrrolide), in order to evaluate them as catalysts for the homocoupling of 3‐methyl‐1‐butene. They were compared with Mo(NC 6F5)(CHCM e2Ph)(HMTO )(PP hMe2)Cl (HMTO = 2,6‐dimesitylphenoxide), Mo(NC 6F5)(CHCM e2Ph)(HIPTO )(PP hMe2)Cl (HIPTO = 2,6‐di(2′,4′,6′‐triisopropylphenyl)phenoxide), and several other Mo and Ru catalysts. In the best cases turnover numbers (TON s) of 400 – 700 were observed for the homocoupling of 3‐methyl‐1‐butene in a closed vessel (ethylene not removed). -
Summary Alfalfa (
Medicago sativa L.) is a perennial flowering plant in the legume family that is widely cultivated as a forage crop for its high yield, forage quality and related agricultural and economic benefits. Alfalfa is a photoperiod sensitive long‐day (LD) plant that can accomplish its vegetative and reproductive phases in a short period of time. However, rapid flowering can compromise forage biomass yield and quality. Here, we attempted to delay flowering in alfalfa using multiplex CRISPR/Cas9‐mediated mutagenesis ofFLOWERING LOCUS Ta1 (MsFTa1 ), a key floral integrator and activator gene. Four guide RNAs (gRNAs) were designed and clustered in a polycistronic tRNA–gRNA system and introduced into alfalfa byAgrobacterium ‐mediated transformation. Ninety‐six putative mutant lines were identified by gene sequencing and characterized for delayed flowering time and related desirable agronomic traits. Phenotype assessment of flowering time under LD conditions identified 22 independent mutant lines with delayed flowering compared to the control. Six independentMsfta1 lines containing mutations in all four copies ofMsFTa1 accumulated significantly higher forage biomass yield, with increases of up to 78% in fresh weight and 76% in dry weight compared to controls. Depending on the harvesting schemes, many of these lines also had reduced lignin, acid detergent fibre (ADF) and neutral detergent fibre (NDF) content and significantly higher crude protein (CP) and mineral contents compared to control plants, especially in the stems. These CRISPR/Cas9‐editedMsfta1 mutants could be introduced in alfalfa breeding programmes to generate elite transgene‐free alfalfa cultivars with improved forage biomass yield and quality.
