(Submitter supplied) As a major plant abiotic stress, drought stress suppresses crop yield performance severely. However, the trade-off between crop drought tolerance and yield performance becomes a great challenge in drought-resistant crop breeding. Several phytohormones have been reported to participate in plant drought response, including gibberellin (GA), which also plays an important role in plant growth and development. more...

(Submitter supplied) Zebra leaf is a special phenotype of variegated leaf in monocotyledonous plant. Here, we characterized a mutant zebra10 (zb10) in maize, which displays defective chloroplast development in white section of leaves at the seedling stage and pale-white kernels. Map based cloning revealed that ZB10 encodes plastid terminal oxidase (ZmPTOX) which is localized in chloroplasts. ZmPTOX protein is highest expressed in leaves and also highly expressed in endosperm. more...

(Submitter supplied) High temperature is increasingly becoming one of the prominent environmental factors affecting the growth and development of maize (Zea mays L.). Therefore, it is critical to identify key genes and pathways related to heat stress (HS) tolerance in maize. Here, we identified a heat-resistant (Z58D) and heat-sensitive (AF171) maize inbred lines at seedling stage. Transcriptomic analysis identified 3,006 differentially expressed genes (DEGs) in AF171 and 4,273 DEGs in Z58D under HS treatments, respectively. more...

(Submitter supplied) Fertile pollen is critical for the survival, fitness and dispersal of flowering plants, and directly contributes to crop productivity. Extensive mutational screening studies have been carried out to dissect the genetic regulatory network determining pollen fertility, but we still lack fundamental knowledge about whether and how pollen fertility is controlled in natural populations. We used a genome-wide association study (GWAS) to show that ZmGEN1A and ZmMSH7, two DNA repair-related genes, confer natural variation in maize pollen fertility. more...

(Submitter supplied) The biochemistry of C4 photosynthesis relies on a specific suite of leaf functional properties, often referred to as Kranz anatomy, where there is increased vein density and the proportion of bundle sheath cells surrounding the veins compared to C3 photosynthesizing species. From a suite of putative Kranz anatomy regulators, TML was identified. Loss of function tml mutations lead to the development of large lateral veins in positions normally occupied by smaller intermediate veins in both C3 and C4 species tested. more...

(Submitter supplied) P1 is the major QTL for maysin and chlorogenic acid accumulation in silk. Both compounds were important for plant defenses. Silk is an important reproductive organ that is critical for good seed setting in corn ear and needs to be protected against various stresses, therefore, metabolics compounds (ex: phenolics) were highly enriched in silk. Here we characterize transcriptome changes in maize protoplast, and natural variants of P1 silks, and pericards to characterize the regulatory landscape. more...
