Doil Choi and colleagues report the genome sequence of hot pepper, Capsicum annuum, as well resequencing two cultivated peppers a wild species, chinense. Comparative genomic analysis across Solanaceae provides insights into expansion, pungency, ripening disease resistance in peppers. Hot pepper (Capsicum annuum), one oldest domesticated crops Americas, is most widely grown spice crop world. We whole-genome sequencing assembly (Mexican landrace annuum cv. CM334) at 186.6× coverage. also de...
Significance Eukaryotic algae, which play a fundamental role in global CO 2 fixation, enhance the performance of carbon-fixing enzyme Rubisco by placing it into an organelle called pyrenoid. Despite ubiquitous presence and biogeochemical importance this organelle, how assembles to form pyrenoid remains long-standing mystery. Our discovery abundant repeat protein that binds represents critical advance our understanding biogenesis. The sequence suggests elegant models explain structural...
A phase-separated, liquid-like organelle called the pyrenoid mediates CO
If the highly efficient C 4 photosynthesis pathway could be transferred to crops with 3 there yield gains of up 50%. It has been proposed that multiple metabolic and developmental modifications associated are underpinned by relatively few master regulators have allowed evolution more than 60 times in flowering plants. Here we identify a component one such regulator consists pair cis -elements located coding sequence genes preferentially expressed bundle sheath cells leaves. These motifs...
MicroRNAs (miRNAs) are a class of non-coding RNAs approximately 21 nt in length which play important roles regulating gene expression plants. Although many miRNA studies have focused on few model plants, miRNAs and their target genes remain largely unknown hot pepper (Capsicum annuum), one the most crops cultivated worldwide. Here, we employed high-throughput sequencing technology to identify extensively from 10 different libraries, including leaf, stem, root, flower, six developmental stage...
This study established the heat levels for several high-heat chile pepper ( Capsicum chinense ) varieties (Trinidad Moruga Scorpion, Bhut Jolokia, Trinidad Douglah Chocolate, and 7-pot Jonah) to determine which variety has highest average measured level relatedness of peppers using molecular analysis. In replicated trials with appropriate controls at Las Cruces, NM, results show two ‘Trinidad Scorpion’ plants reached more than million Scoville units (SHU). is first confirmation fruit...
Engineering C4 photosynthesis into C3 crops could substantially increase their yield by alleviating photorespiratory losses. This objective is challenging because the pathway involves complex modifications to biochemistry, cell biology, and anatomy of leaves. Forward genetics has provided limited insight mechanistic basis these properties, there have been no reports significant quantitative intraspecific variation attributes that would allow trait mapping. Here, we show accessions species...
C4 photosynthesis has evolved by repurposing enzymes found in C3 plants. Compared with the ancestral state, accumulation of cycle proteins is enhanced. We used de-etiolation C4Gynandropsis gynandra and C3Arabidopsis thaliana to understand this process. gene expression chloroplast biogenesis G. were tightly coordinated. Although genes showed similar induction patterns, gynandra, more strongly induced than orthologs from A. thaliana. In vivo binding TGA homeodomain as well light-responsive...
A novel disease resistance inhibitor gene (inhibitor of P. capsici [Ipcr]), found in the chile pepper (Capsicum annuum) variety ‘New Mexico Capsicum Accession 10399’ (NMCA10399), inhibits to Phytophthora but not other species Phytophthora. When a highly capsici-resistant was hybridized with NMCA10399, resultant F 1 populations, when screened, were completely susceptible for root rot and foliar blight syndromes, despite dominance inheritance pepper. The 2 population displayed 3:13...
Reducing photorespiration in C3 crops could significantly increase rates of photosynthesis and yield. One method to achieve this would be integrate C4 into species. This objective is challenging as it involves engineering incompletely understood traits leaves, including complex changes their biochemistry, cell biology, anatomy. Quantitative genetics selective breeding offer underexplored routes identify regulators these processes. We first review examples natural intraspecific variation well...
Abstract A sustainable food supply is vital for addressing the challenges of a growing global population and climate change. Gynandropsis gynandra , nutritious C 4 orphan crop native to Africa Asia, thrives in low-input agricultural systems, making it valuable candidate future security. This also serves as model studying photosynthesis. However, research on its genetic improvement limited. In this study, two mapping populations from diverse parental lines were used identify Quantitative...

ABSTRACT C 4 photosynthesis has evolved independently in over sixty lineages and so doing repurposed existing enzymes to drive a carbon pump that limits the RuBisCO oxygenation reaction. In all cases, gene expression is modified such proteins accumulate levels matching those of photosynthetic apparatus. To better understand this rewiring we undertook RNA- DNaseI-SEQ on de-etiolating seedlings Gynandropsis gynandra , which sister 3 Arabidopsis. Changes chloroplast ultrastructure were...
