One of the most striking features of the plant root hair cell tissue specimen is its microscopic structure. Under the microscope, the intricate network of root hairs and their associated cells becomes apparent, highlighting the specialized adaptations that enable these cells to effectively absorb water...
little or no cuticle (offering minimum resistance for oxygen diffusion) and dense cytoplasm studded with mitochondria at Ule tip of the root hairs, are some of the special ultrastructural adaptations of root hairs which offer an indication that at least one of their main functions involves ...
Programmed Cell Death PRD: Partial Root zone Drying PERKs: Proline-rich Extensin-like Receptor Kinases PIP: Plasma membrane Intrinsic Protein PM: Plasma Membrane PRX: Peroxiredoxins PTI: Pattern-Triggered Immunity RALF34: Rapid Alkalinization Factor RBOHD and F: Respiratory Burst Oxidase...
(Galway et al.1994) form a protein complex and enhance the expression ofGLABLA2(GL2) which functions as a negative regulator of root hair formation (Masucci et al.1996; Di Cristina et al.1996). Lack of GL2 function causes ectopic root hair formation from non-hair cell files. Interestingly...
1). The LP stress promoted lateral root development and root hair elongation26, and the increase in root surface area should facilitate better nutrient uptake from the soil27. Previously, it was claimed that phosphorus-efficient varieties improved phosphorus uptake by increasing the number and size ...
Roots are one of the earliest adaptations that enabled plants to colonize land (Kenrick & Crane, 1997). They perform essential functions necessary for the survival and development of plants, such as anchoring them to a substrate, providing mechanical support, storingphotoassimilates, and absorbing ...
3. Root system development Root development can be divided in two main stages: a) embryonic development (ED) and b) post-embryonic development (PED). During the ED, through a suite of highly regulated and reproducible stages, the fertilized egg cell rises into an embryo. In the embryo, ...
Since the top part of soils is often richer in phosphorus, adaptations of root architecture that increase root density in the upper parts of the soil favor phosphorus-uptake efficiency. This is achieved by a shallower growth angle of axial roots, leading to a greater length of roots in the ...
Environmental stresses as major threats to global food security in the twenty-first century and improving biomass production and seed yield per area of crop plants become very critical. Plants are sessile organisms that cannot escape from environmental c
(such as nitrogen fixing bacteria and mycorrhizal fungi) to aid them in their quest for nutrients. Finally, some key biotic and abiotic constraints on root development and function in the soil environment are examined and some of the adaptations roots have evolved to counter such stresses ...
