The present survey of leaf-blade trichomes Mendoncia used SEM and light microscopy to investigate the diversity trichome types in Neotropical Paleotropical species genus. eglandular are filiform, uniseriate, with asymmetric epidermal cells arranged radially around trichome, these may be short or elongated, oriented two groups. These cells, when covered epicuticular wax, forming smooth thick pla...

Cell differentiation is generally tightly coordinated with the cell cycle, typically resulting in a nondividing cell with a unique differentiated morphology. The unicellular trichomes of Arabidopsis are a well-established model for the study of plant cell differentiation. Here, we describe a new genetic locus, SIAMESE (SIM), required for coordinating cell division and cell differentiation durin...

Selective sensation of sound by the plant Arabidopsis thaliana may enable timely upregulation defensive compounds to protect against caterpillars plant’s primary insect herbivore. Vibration leaf trichomes has been shown occur over frequency ranges that are appropriate for responding these caterpillars, but distribution trichome shapes and sizes a means range sounds could possibly be transduced....

As often reminded to the readers in articles or reviews which deal with plant adaptation to their environment, higher plants are sessile organisms, a life habit which does not allow them to escape danger or to move to avoid adverse conditions. This environmental pressure has led to a myriad of adaptations, which are reflected in the vast diversity of plant habitats, morphologies, life cycles an...

In Arabidopsis, trichome formation is regulated by the interplay of R3 MYBs and several others transcription factors including the WD40-repeat protein TRANSPARENT TESTA GLABRA1 (TTG1), the R2R3 MYB transcription factor GLABRA1 (GL1), the bHLH transcription factor GLABRA3 (GL3) or ENHANCER OF GLABRA3 (EGL3), and the homeodomain protein GLABRA2 (GL2). R3 MYBs including TRICHOMELESS1 (TCL1), TCL2,...

Each cotton fiber is a single-celled seed trichome or hair, and over 20,000 fibers may develop semi-synchronously on each seed. The molecular basis for seed hair development is unknown but is likely to share many similarities with leaf trichome development in Arabidopsis. Leaf trichome initiation in Arabidopsis thaliana is activated by GLABROUS1 (GL1) that is negatively regulated by TRIPTYCHON ...
