The plant vascular system, and specifically the phloem, plays a pivotal role in allocation of fixed carbon to developing sink organs. Although the processes involved in loading and unloading of sugars and amino acids are well characterized, little information is available regarding the nature of other metabolites in the sieve tube system (
Seed development largely depends on the long‐distance transport of sucrose from photosynthetically active source leaves to seed sinks. This source‐to‐sink carbon allocation occurs in the phloem and requires the loading of sucrose into the leaf phloem and, at the sink end, its import into the growing embryo. Both tasks are achieved through the function of

Summary STS ) at specific sites along the pathway. Here, we elucidate spatial features of metabolite composition mapped with phloem enzymes along the cucurbitSTS . Phloem sap (PS ) was collected from the loading (source), unloading (apical sink region) and shoot–root junction regions of cucumber, watermelon and pumpkin. OurPS analyses revealed significant differences in the metabolic and proteomic profiles both along the source–sink pathway and between theSTS s of these three cucurbits. In addition, metabolite profiles established forPS and vascular tissue indicated the presence of distinct compositions, consistent with the operation of theSTS as a unique symplasmic domain. In this regard, at various locations along theSTS we could map metabolites and their related enzymes to specific metabolic pathways. These findings are discussed with regard to the function of theSTS as a unique and highly complex metabolic space within the plant vascular system. -
Abstract Wetlands play an important role in regulating the atmospheric carbon dioxide (
CO 2) concentrations and thus affecting the climate. However, there is still lack of quantitative evaluation of such a role across different wetland types, especially at the global scale. Here, we conducted a meta‐analysis to compare ecosystemCO 2fluxes among various types of wetlands using a global database compiled from the literature. This database consists of 143 site‐years of eddy covariance data from 22 inland wetland and 21 coastal wetland sites across the globe. Coastal wetlands had higher annual gross primary productivity (GPP ), ecosystem respiration (R e), and net ecosystem productivity (NEP ) than inland wetlands. On a per unit area basis, coastal wetlands provided largeCO 2sinks, while inland wetlands provided smallCO 2sinks or were nearlyCO 2neutral. The annualCO 2sink strength was 93.15 and 208.37 g C m−2for inland and coastal wetlands, respectively. AnnualCO 2fluxes were mainly regulated by mean annual temperature (MAT ) and mean annual precipitation (MAP ). For coastal and inland wetlands combined,MAT andMAP explained 71%, 54%, and 57% of the variations inGPP ,R e, andNEP , respectively. TheCO 2fluxes of wetlands were also related to leaf area index (LAI ). TheCO 2fluxes also varied with water table depth (WTD ), although the effects ofWTD were not statistically significant.NEP was jointly determined byGPP andR efor both inland and coastal wetlands. However, theNEP /R eandNEP /GPP ratios exhibited little variability for inland wetlands and decreased for coastal wetlands with increasing latitude. The contrasting ofCO 2fluxes between inland and coastal wetlands globally can improve our understanding of the roles of wetlands in the global C cycle. Our results also have implications for informing wetland management and climate change policymaking, for example, the efforts being made by international organizations and enterprises to restore coastal wetlands for enhancing blue carbon sinks. -
Summary The altered carbon assimilation pathway of crassulacean acid metabolism (
CAM ) photosynthesis results in an up to 80% higher water‐use efficiency than C3photosynthesis in plants making it a potentially useful pathway for engineering crop plants with improved drought tolerance. Here we surveyed detailed temporal (diel time course) and spatial (across a leaf gradient) gene and microRNA (miRNA ) expression patterns in the obligateCAM plant pineapple [Ananas comosus (L.) Merr.]. The high‐resolution transcriptome atlas allowed us to distinguish betweenCAM ‐related and non‐CAM gene copies. A differential gene co‐expression network across green and white leaf diel datasets identified genes with circadian oscillation,CAM ‐related functions, and source‐sink relations. Gene co‐expression clusters containingCAM pathway genes are enriched with clock‐associatedcis ‐elements, suggesting circadian regulation ofCAM . About 20% of pineapple microRNA s have diel expression patterns, with several that target keyCAM ‐related genes. Expression and physiology data provide a model forCAM ‐specific carbohydrate flux and long‐distance hexose transport. Together these resources provide a list of candidate genes for targeted engineering ofCAM into C3photosynthesis crop species. -
Summary Despite well established roles of micro
RNA s in plant development, few aspects have been addressed to understand their effects in seeds especially on lipid metabolism. In this study, we showed that overexpressing microRNA 167A (miR167OE ) in camelina (Camelina sativa ) under a seed‐specific promoter changed fatty acid composition and increased seed size. Specifically, the miR167OE seeds had a lower α‐linolenic acid with a concomitantly higher linoleic acid content than the wild‐type. This decreased level of fatty acid desaturation corresponded to a decreased transcriptional expression of the camelina fatty acid desaturase3 (Cs ) in developing seeds. MiR167 targeted the transcription factor auxin response factor (CsFAD 3ARF 8) in camelina, as had been reported previously in Arabidopsis. Chromatin immunoprecipitation experiments combined with transcriptome analysis indicated that CsARF 8 bound to promoters of camelina andbZIP 67 genes. These transcription factors directly or through theABI 3ABI 3‐bZIP 12 pathway regulateCs expression and affect α‐linolenic acid accumulation. In addition, to decipher the miR167A‐CsFAD 3ARF 8 mediated transcriptional cascade forCs suppression, transcriptome analysis was conducted to implicate mechanisms that regulate seed size in camelina. Expression levels of many genes were altered in miR167FAD 3OE , including orthologs that have previously been identified to affect seed size in other plants. Most notably, genes for seed coat development such as suberin and lignin biosynthesis were down‐regulated. This study provides valuable insights into the regulatory mechanism of fatty acid metabolism and seed size determination, and suggests possible approaches to improve these important traits in camelina. -
Abstract In habitats where resource availability declines during the growing season
, selection may favor early‐flowering individuals. Under such ephemerally favorable conditions, late‐blooming species (and individuals) may be particularly vulnerable to resource limitation of seed production. In California, a region prone to seasonal drought, members of the annual genusClarkia are among the last to flower in the spring. We compared pollen limitation (PL ) of seed set and outcrossing rates between early‐ and late‐flowering individuals in two mixed‐matingClarkia taxa to detect whether flowering time is associated with changes in seed set due to resource depletion,PL , or increased selfing. In 2008–2010, we hand‐pollinated one flower on a total of 1855 individual plants either Early (near the onset of flowering) or Late (near the end of flowering) in the flowering season and compared seed set to adjacent, open‐pollinated flowers on the same stem. To assess the contribution of pollen quality to reproduction, we first (2008) used allozymes to estimate outcrossing rates of seeds produced by Early and Late open‐pollinated flowers. Second (2009), we conducted an anther‐removal experiment to estimate self‐pollen deposition. Seed set inClarkia unguiculata was not pollen‐limited.Clarkia xantiana ssp. xantiana was pollen‐limited in 2008 and 2010, but not 2009.PL did not differ between Early and Late treatments. In both taxa, seed set of Early flowers was greater than Late flowers, but not due toPL in the latter. Reproduction was generally pollinator‐dependent. Most pollen deposition was xenogamous, and outcrossing rates were >0.7 – and similar between Early and Late periods. These results suggest that pollen receipt and pollen quality remain seasonally consistent. By contrast, the resources necessary to provision seeds decline, reducing the fitness benefits associated with resource allocation to ovules.
