The results revealed 36 and 31 species in arid and …

Systematics Value Of Micromorphological And Palynological Characters In Stenocephalum Sch.Bip. (Vernonieae, Asteraceae), Maria Betiana Angulo, Laura Chalup, Massimiliano Dematteis

Turkish Journal of Botany

Micromorphological and palynological characters of all Stenocephalum Sch.Bip. species (Vernonieae, Asteraceae) were analyzed to evaluate their reliability as taxonomic markers at generic level and discussed in relation to other genera of the subtribe Lepidaploinae. Characters such as pubescence of corollas and cypselae showed glandular and nonglandular trichomes allowing differentiation among related species. Apical appendages without glandular trichomes, caudate anthers, and carpopodium structure are common characteristics among Stenocephalum species. With the exceptions of S. megapotamicum and S. tragiaefolium, almost all species of the genus showed style bases without basal nodes for the first time. Crystals on the fruits wall were also …

Currently, MW holds 331 type specimens of 285 taxa described from Anatolia-19 holotypes, 47 isotypes, 48 isolectotypes, and 203 syntypes.

The Effects Of Mycorrhizal Inoculant And Micronutrients On Early Plant Establshment During A Tallgrass Prairie Reconstruction, Christopher L. Barber

Dissertations and Theses @ UNI

Symbiotic relationships between mycorrhizal fungi and land plants are one of the most widespread examples of symbiosis on Earth yet there is still much to discover about their ecological impacts.

Prairie reconstructions are often done on highly disturbed sites such as reclaimed cropland, turf grass, and road rights-of-way. Disturbed soils often lack adequate quantities of both mycorrhizal fungi and micronutrients. I hypothesized that inoculated seeds with mycorrhizal spores or micronutrient seed treatments will aid in the early establishment of a tallgrass prairie.

To test this hypothesis four treatments (T1 control, T2 mycorrhizal, T3 micronutrient, and T4 mycorrhizal and micronutrient) were …

Mac3a And Mac3b, Two Core Subunits Of The Mos4-Associated Complex, Positively Influence Mirna Biogenesis, Shengjun Li, Kan Liu, Bangjun Zhou, Mu Li, Shuxin Zhang, Lirong Zeng, Chi Zhang, Bin Yu

Center for Plant Science Innovation: Faculty Publications

MAC3A and MAC3B are conserved U-box containing proteins in eukaryotes. They are subunits of the MOS4-associated complex (MAC) that plays essential roles in plant immunity and development in Arabidopsis. However, their functional mechanisms remain elusive. Here we show that Arabidopsis thaliana MAC3A and MAC3B act redundantly in microRNA (miRNA) biogenesis. Lack of both MAC3A and MAC3B in the mac3b mac3b double mutant reduces the accumulation of miRNAs, causing elevated transcript levels of miRNA targets. mac3a mac3b also decreases the levels of primary miRNA transcripts (pri-miRNAs). However, MAC3A and MAC3B do not affect the promoter activity of genes encoding miRNAs ( …

Regulation Of Local Auxin Metabolism During Soybean Nodule Development, Suresh Damodaran

Electronic Theses and Dissertations

Legume-rhizobia symbiosis leads to the development of secondary root organs called nodules. Rhizobia bacteria housed inside nodules assimilate atmospheric nitrogen and convert them into plant usable forms thereby reducing the need for fertilizer application in crop legumes like soybean. Nodule development is a coordinated process orchestrated by multiple plant hormones. In soybean, the auxin responsive gene expression was detected in nodule primordia and in the periphery of mature nodules, primarily in nodule vasculature. Auxin hypersensitivity reduces nodule formation in soybean and also polar auxin transport inhibition at the site of nodule development is not crucial for determinate nodule formation. Therefore, …

Map-Based Cloning And Molecular Characterization Of The Seed Dormancy 10 Locus In Rice (Oryza Sativa L.), Wirat Pipatpongpinyo

Electronic Theses and Dissertations

Seed dormancy is a key adaptive trait of both ecological and agricultural importance. Although many quantitative trait loci (QTL) have been associated with seed dormancy in cereal crops or model plants, a majority of them remain unknown for molecular identities and functions. Cereal crops and wild/weedy relatives usually have weak and strong seed dormancy, respectively, such as Asian cultivated rice vs. weedy rice (Oryza sativa L.). Previous research identified a set of seed dormancy QTL, including qSD10, in single plant-derived BC₁F₂ and BC₁F₃ populations from the backcross between the weedy rice line SS18-2 …

Application Of Acoustic Emission And Machine Learning To Detect Codling Moth Infested Apples, Mengxing Li, Nader Ekramirad, Ahmed Rady, Akinbode A. Adedeji

Biosystems and Agricultural Engineering Faculty Publications

Incidence of codling moth (CM) (Cydia pomonella L.) infestation in apples has been a major concern in North America for decades. CM larvae bore deep into the fruit, making it unmarketable. An effective noninvasive method to detect larvae-infested apples is necessary to ensure that apples are CM-free in post-harvest processing. In this study, a novel approach using an acoustic emission (AE) system and subsequent machine learning methods was applied to classify larvae-infested apples from intact apples. 'GoldRush‘ apples were infested with CM neonates and stored at the same conditions as intact apples. The AE system was used to collect …

Turkish Journal of Botany

Oxytropis glandulosa Turcz. (Fabaceae) is a rare perennial plant endemic to Buryatia (Russia). We sequenced three intergenic spacers (the psbA−trnH, trnL−trnF, and trnS−trnG) of chloroplast DNA (cpDNA) in specimens of four populations from two geographic regions (Barguzin and Yeravna depressions) within this species range. The levels of haplotype and nucleotide diversity varied in the range of 0.133−0.911 and 0.0002−0.0059, respectively. The highest values of these parameters are characteristic of populations located in the Barguzin depression. Variable sites detected within the intergenic spacers allowed the identification of eleven haplotypes; nine of them were found in the populations from the Barguzin depression …
