1. Anatomical Assessment of Root Formation and Tuberization in Cassava (Manihot esculenta Crantz)

Abstract:
... Formation of storage root organs in cassava (Manihot esculenta) is poorly understood, but considered to occur when a subset of fibrous roots receive unknown signals to undergo secondary thickening. Large amounts of secondary xylem parenchyma are then produced in which starch is synthesized and stored. Anatomical studies were undertaken to examine rhizogenesis from greenhouse-grown cassava stem cut ...

Bayesian theory; Saccharum; biosynthesis; cell walls; correlation; culms; developmental stages; ethanol production; genes; genotype; internodes; lignin; lignocellulose; pith; sugarcane; transcription (genetics); transcription factors
Abstract:
... Cell wall recalcitrance, which is conferred in part by lignin, is the main bottleneck in lignocellulosic ethanol production. Transcription factors (TFs) have been suggested as targets to reduce or modify lignin. Here we analysed the expression profile of nine sugarcane TFs, their relationships with genes of the monolignol biosynthesis pathway, and their effects on lignin content and composition. O ...

Abstract:
... Seed dormancy is an important trait during the domestication of major crops. Dormant seeds are unable to germinate under conditions normally suitable for non-dormant seeds. Quantitative trait loci (QTLs) and genes affecting seed dormancy in sorghum remain largely unknown. To identify the genomic regions controlling seed dormancy in sorghum, we produced two F₂ segregating populations from two cross ...

4. MicroRNA Networks in Plant-Microorganism Interactions

Author:

Subject:
abiotic stress; beneficial microorganisms; biochemical pathways; disease resistance; gene expression; genes; microRNA; plant diseases and disorders; plant pathogens; tropics
Abstract:
... MicroRNA constitutes an important class of small RNAs that negative regulates post-transcriptionally protein-coding genes. MiRNA-guided gene regulation has been reported as essential for developmental processes and for plant proper responses to biotic and abiotic stresses. When plants are exposed to microorganisms, they resort to various strategies to either establish a beneficial association, or ...

5. Physiological and Biochemical Changes During Heat Stress Induced Browning of Detached Backhousia myrtifolia (Cinnamon Myrtle) Tissues

Abstract:
... Postharvest discolouration is found in leaf and floral tissues of Backhousia myrtifolia (Cinnamon myrtle). Towards discerning the biochemical mechanisms, heat-induced browning was investigated. Differential browning behaviour was observed for green versus yellowed leaves. Initial pre-treatment chlorophyll contents (Chl a and b) and chlorophyll fluorescence (CF) were measured for both coloured leav ...
