cell death (PCD) has been observed in various developmental processes
in plants such as tracheary element differentiation, root cap shedding,
androgenesis, leaf senescence, aerenchyma formation etc. PCD also
appears to play an important role in leaf development in species with
perforated leaves, although almost nothing is known about this process.
Therefore, I am interested in looking at whether cell death pattern
during formation of perforations is a form of PCD or not. In my study
Monstera obliqua and Aponogeton madagascariensis
have been selected as model systems. |

Julie Kang PhD student Research interestMy research focuses on the role of cell cycling during
vascular development in shoots and leaves of Arabidopsis. Using a cyclin1At::GUS construct, I
have been able to characterize the spatial and temporal patterns of cell
cycling in adult wild type leaves.
This pattern correlates almost exactly to that of the ATHB-8::GUS
construct, which is an early marker of procambial strand formation. ATHB-8::GUS was also used as a
marker to determine shoot vascular architecture in wild type plants during
vegetative and early and late flowering stages of development. I am currently studying two mutants to
determine how suppression of cell cycling affects the radial and longitudinal
vascular pattern in leaves of Arabidopsis. |

Riyadh Muhaidat PhD student; homepage Research interestMy PhD research interests focus on pieces of the
structure- function relationship in interesting taxa of C4 dicots
in which the syndrome has independently evolved. In contrast to grasses
in which the syndrome has evolved in three main biochemical subtypes
(NADP-ME; NAD-ME; PEP-CK), only two (NADP-ME and NAD-ME) have been
identified in dicotyledonous species of examined so far. I am characterizing
the biochemistry of selected groups of C4 dicots that have not yet
been well studied. In addition, I am searching for anatomical criteria
that distinguish the subtypes from each other and/or to subtype C4
dicot species based on anatomical screens, hence the chloroplasts
have a centripetal position in both subtypes. Convergence of Kranz
anatomy between C4 species of Haloxylon (Chenopodiaceae) and
Calligonum (Polygonaceae) is my current research question underway. |

Athena McKown
PhD student Research interestI
am currently investigating the development and evolution of vein pattern in
C4 dicots. The development of venation in leaves has many implications on
evolution. Currently, the mechanisms by which C4 species have altered their
vein pattern to allow C4 biochemistry to function from the C3 progenitor
pattern is unknown. I am using Flaveria (Asteraceae) as my model
organism, as this genus possesses species that are classified as strict C3
and C4, as well as intermediate species; C3-C4 and C4-like. |

undergraduate
student; homepage Research interestI
am an undergraduate student and working on a 4th year research
project focusing on heteroblastic variation in leaf vein pattern in Arabidopsis.
I am comparing the development of vein density in juvenile, adult rosette and
cauline leaves using a genetic marker for early expression of procambium
(ATHB-8) in wild-type Arabidopsis and also comparing vein pattern in a
number of Arabidopsis mutants. I am interested in vein pattern plasticity
to altered light quantity and quality, and in the relationship between leaf
shape and vein pattern. |

Ada Wong undergraduate student Research interestI am a 4th year botany undergraduate student
and working as a lab assistant in the Dengler lab. This summer, I
completed a 4th year research project titled “The convergence
of Kranz anatomy in photosynthetic stems of Haloxlyon
(Chenopodiaceae) and Calligonum
(Polygonaceae) species.” This work is related to the PhD project of
Riyadh Muhaidat. |
