Homeotic mutants, that is, mutants with a normal organ in a place where an organ of another
type is typically found, were first recognized in plants. The earliest descriptions of mutants in …

Although seeds have been the subject of extensive studies for many years, their seed coats
are just beginning to be examined from the perspective of molecular genetics and control of …

Abnormal high temperature (HT) caused by global warming threatens plant survival and
food security, but the effects of HT on plant organ identity are elusive. Here, we show that …

Abstract APETALA2 (AP2) plays a central role in the establishment of the floral meristem, the
specification of floral organ identity, and the regulation of floral homeotic gene expression in …

We identified Arabidopsis thaliana sterility mutants by screening T-DNA and EMS-
mutagenized lines and characterized several male-sterile mutants with defects specific for …

APETALA2 (AP2) plays an important role in the control of Arabidopsis flower and seed
development and encodes a putative transcription factor that is distinguished by a novel …

To understand better the role of genes in controlling ovule development, a female-sterile
mutant, aintegumenta (ant), was isolated from Arabidopsis. In ovules of this mutant …

DREB transcription factors play key roles in plant stress signalling transduction pathway,
they can specifically bind to DRE/CRT element (G/ACCGAC) and activate the expression of …

Ovules play a central role in plant reproduction, generating the female gametophyte within
sporophytic integuments. When fertilized, the integuments differentiate into the seed coat …

Flowers are the most complex structures of plants. Studies of Arabidopsis thaliana, which
has typical eudicot flowers, have been fundamental in advancing the structural and …
